I bought a corsair 750w bronze PSU (used!) for my first build in 2011. It's still going strong in my current PC. I know I should have upgraded some time ago, wouldn't like it suddenly failing and ruining something. I'm planning to retire it into a shelve for display, it isn't pretty but we've been through a lot together: moves, girlfriends, my try-hard Overwatch phase, unemployment, it just never quit on me.
Have to appreciate something trusty.
That power supply is motovated
Was it an AX750? The old Corsair AX series was made by Seasonic, I retired mine last year because it was 10 years old. Don't care to let it burn out and modular meant I could cut 80% of the wires out of my case.
Quality power supplies will usually fail inwards and not fry your system.
My computer has a Corsair HX520 that I bought in 2009. I don't know who made it but it has fulfilled its duties.
Never skimp on the psu folks
My braindead friend did now he have to buy another one.
@@Ninja40K that's why I never skimp out.. always a brand name and always more the recommended 👌.. never had any issues doing that
Never ever. I bought an ax1200 6 years ago, and i will only replace it with something better.
@@lk5388 smart man 😀
I've been using the same one since 2012 lol 3 builds later still going 10600k/3060ti ftw
This dude's always working hard to bring us straight tech knowledge
You should always put a piece of paper with the model info into the bag of unused cables for your modular power supply. That way you can verify that you're only using the proper cables later on. Don't mix and match modular cables.
Gonna be doing my first build soon, this is great advice. Thank you!
good advice!
I just kept the psu box in a tub with my mobo box, full of spare bits😅
Or if you want, just leave em in the PSU’s box.
I remember reading Custom PC Magazine (in the UK) in the early/mid 2000's. Cheap PSU's regularly exploded when they were doing PSU lab tests. It was the one component they recommended spending good money on.
Thankfully these days, PSU's seem much more reliable.
Hah, yes... I learnt the hard way by getting a 400w colours psu for £18.02. It's what I could afford at -time- the time.... and yes it fried a PC. The amount of colourful language that ensued would have bought me a new PC 😂.
Yeah these days you're safe with most Gold PSUs. Brands like EVGA, Seasonic, Super Flower, Corsair etc are reliable.
Oh man, anyone remember those completely non-modular Great Wall 500W ATX PSU's that would literally pop and catch fire in SLI rigs that were using too many six pin pigtails?
Exploding power supplies are still a thing. Just look up Gigabytes problem from just a couple years ago.
I had an Enermax explode on me back in the days. Scary times! I never used cheap PSUs. Always from well known manufacturers. These days, I always use Seasonic in every system I build. They never disappointed.
I had to gut the room where my computers are for some electrical issues. So I rewired it with two 20a circuits, and I'm glad I did. But I think "overspending" on a power supply is some of the best money you can spend on a build because a really good power supply can easily last you 10 years, so long as you don't outgrow it's rated power.
-😆 someone releases a new generation of GPU which requires a new PSU format to prevent the card overloading your PSU and burning your house down
@@richardhockey8442 It was because the connector wasn't plugged in all the way. Gamers Nexus proved it
500w raidmax bronze gave me 8 years of usage.. Its still working perfectly fine. Got the 1000w FSP hydro G now
@@richardhockey8442 The irony of all that is that there was no need for the new connector outside NVIDIA needing something smaller for their tiny boards. Two eight pins just don't fit, and can provide the same power, technically more, with 16ga wire.
@@notlNSIGHT But they concluded that it's more difficult to insert than the previous cables. So it was user error, but user error brought on by a design issue.
Just upgraded from a Seasonic 550W semi modular to a Corsair HX750 to support my 3070 and 5800X and couldn't be happier with the performance. Great buy!
Using a good brand late model 850w fully modular Gold PSU on my AMD 5000 series Nvidia RTX 30 Series system. My GPU recommended a 750w PSU so I chose 850w for some headroom, especially with the known RTX 30 Series GPU transient power spikes - which have occurred several times on my system. It's all working out real nice. Thanks for covering this topic, Jay!
Did the same for overclocking
And GPU power recommendations are always really high balling it so my God do you have some headroom in terms of wattage.
@@Jenna_Talia On Nvidia cards in particular ramping up the settings will see momentary (
Nice one man, I have a 4080 and a 5900x on an 850w psu. 4080 pulls 350w and the 5900x pulls 170w. I’ve seen people recommending 1000w psu’s for the 4080 it’s absurd. Even with a 13900k and a 4080 you’d still have 250w of headroom.
@@MushToast_ Thats probably back from the days where past 50% PSU capacity your effeciency basicly droped to 80% or lower. Not so long ago the golden rule was to take your CPU+GPU draw and double it when choosing PSUs to keep it in the most efficient part of the curve.
This is so true. I bought a power supply about 15 years ago, a semi modular Corsair 1000W, and I stil use it today in my main rig. Yes it was very expensive but worth it.
Dude 15 years ago. 1000w. How big is that mf. That PSU was prob in the space race
Same, admittedly 10 and not 15 years ago but 1000w plat still feels like i can build whatever and not worry
Totally agree, never cheaped out on the PSU and never regretted it!
Cybenetics is a good resource for good power supplies, and they report at 115 and 230V for their efficiency and stability measurements. Great resource for more of that technical information on PSUs for comparison, rather than just the efficiency rating of 80+.
🙂
Thanks……good site.
@Cybenetics ratings rock. They literally perform thousands of checks to the psus.
As a vivid gamer but with casual knowledge of the CPU components... You and PC Builder have tough me soooooo much and I finally build my second rig all based on your tutelage. I am actually doing informed buys now and workarounds thanks to you. My friend that was out of the country was kinda scared that I did not wait for him as he was supposed to build it for me... well, you saved me 100 euro for the work as I can now do it myself! Thanks!
Another "part" that some people overlook, especially when on a budget, isn't actually an internal component, but the monitor. The monitor is the heart of your setup. Spending less the the PC and getting a better monitor is usually worth it
I don't think That's true for me, I mean if I buy computer that is supposed to go for 4K and 144 Hz I should get a monitor supporting 4K in the right size I need to and have space for. I had a kind of 144hz 1080p bad monitor for many years and did not notice much of an upgrade when going to a really good 1080p 144 HZ monitor.
thinks like cooling depends on how quiet I want my PC to be (and sufficient cooling so it doesn't overheat)
components need to be good enough for the FPS and games you want to play
power supply shouldn't be too cheap so it doesn't make your PC break
The heart is the PSU, the monitor is the face.
after 144hz 1ms your monitor does not matter for competitive gaming, and for single player you only really need 60hz 1440p after that you are basically wasting money
It’s pretty hard to tell the difference between 4k and 1440p and then it’s pretty hard to tell the difference between 1080p and 1440p so u might as well get a 1080p high refresh monitor even for the 4090 but that’s just me 🤷🏽♂️
@@heni63 Were you by chance using TN/VA monitors on either your cheap monitor or more expensive one? (or both)
A more expensive TN panel tends to get you a penel that doesn't necessarily "look" better, but performs better. Additionally, a cheap ips panel, within reasons, tends to always look much better than even a higher end TN panel, and VA too most the time.
But That's a big part of why I recommend that people spend a good amount of money on a monitor, I think very few people should buy TN/VA in 2022. I think they should instead buy a 1440p or higher, 144hz or higher IPS panel with a good response times and input delay. If their gpu can't handle 1440p gaming then native 1080p is often better than downscaled 1080p so they may be better off with 1080p, but a high refresh rate makes even just using the computer outside of gaming much more enjoyable
I've had a custom NZXT build for the last 2 years now with an i9-10850K, 3080, and this NZXT C1000 Gold surprisingly enough. Never heard of it when I ordered back in 2020 but I wanted to make sure I had something rated high enough in case I ever upgraded things. Haven't had any issues with it whatsoever, still running strong!
I'm pretty sure it's just a seasonic focus under the nzxt logo.
@@covante4822 You would be correct.
im really digging those vlog style videos as of late. jayz just talking about topics and generating discussions is very nice.
Europe standard is 230v average today. It used to be 220 here in the late 80's when I graduated as an electrician. Not really sure why they cranked it up, but my gues is it was to get a common avg between countries having 210, 220, 240 etc. But most modern PSU's very seldom have issues with +/- 10% voltage variation. In the old days it could be a major issue for Lightbulbs longevity if you happened to live right next to a tranformer station as they usually cranked up the voltage to get the specified 215-220v at the end of the suply line so you could have up to 250v in some circumstances It typically varies between 220 and 240 dependent where you live today.
The 1st PC I built was in 2014 and all the PC building resources I followed to build it had all suggested to not cheap out on the power supply. I went with a full modular Corsair and was practically just as excited about it as I was with all the other parts I chose. It may not ever be something I boast about but I certainly admire the electronics-engineering that went into quality brand and models of modern day PC power supplies every bit as much as I do graphics cards, MOBO's or CPU's. I am sort of a technology fanboy though and power supplies are no exception.
Yo are not the only one that feels that way bud!
I've been running a Seasonic 850 +Gold for the better part of three years now and it's the one thing in the system that hasn't changed. Fantastic PSUs and really decent prices. And to your comment about Canada Jay, yes we also run 110-120 Volts same as you guys. It would be way to difficult to run something else given how interconnected our countries are on just about everything.
Been running close to the same PSU from Seasonic (X850 gold full modular) since 2013 to now. Its run this computer for almost 10 years no problems.
Good company and PSU. They also make supplies for many other companies out there too, if I didin't have an EVGA one I'd probably go with Seasonic.
110-120 volts? Here in europe the old standard is 230v and 400v is the new standard.
interconnection off different voltage level networks is no problem, works in Europe, the things make it possible are called transformer ^^
I have Seasonic PSU's in every system in the house, and all I've built in the last 5 years. Everything from GX850's, GX1000, TX1000's, daughter's rig, my rig, wife's rig, HDPC rig. I used to be a corsair PSU shill for years until I had two fail (one catastrophically), I've had EVGA fail and have run a few others (GW, NZXT), Seasonic is by far the best I've used, and the one time I had an issue with a new one in a family member's build, it was a bad pin on a PCIe pin, and Seasonic shipped me an entirely new replacement in 5 days telling me to ship back the old when when it was convenient.
I built my PC in march 2020 (got really lucky with the prices and timing lol) and am really thankful for channels like yours . I was going to buy a cheap unbranded ketchup/mustard-cabled psu and decided not to. Ended up buying a BeQuiet PurePower 10, 80+ Silver, pretty solid and haven't had any problems!
I love a good psu. Finding one with the right cable lengths and right type of cables. The sleeving and how the cables are made can make a huge difference in how easy or difficult it is to cable manage
I bought a NZXT 750w a few years ago and still no issues. I also love how basic it looks. Nothing crazy and does it’s job
when I worked in the computer department at best buy, I heard multiple stories about the store brand psus literally catching on fire, blowing sparks, and generally being a menace to new builders who didn't know better.
Freaking yikes
When I was enlisted I was an IT MOS in the Army and my first duty station was Germany. I knew nothing about 110v VS 220v. In our workshop/work bench area we had these 220-110 converters because the military won't buy Euro-spec PC's, so we had to use Dell computers imported from the states and use 110v. I popped so many PSUs because I would forget to turn the converter on haha. Thankfully we had a good benchstock of spare PSUs from other PCs where the MOBO had failed or some other component or we'd have old broken life-cycled computers that we could gut but hearing Jay talk about 220v brought back some fond memories. Pop!!!
I was quite conscious of getting the right PSU and I was really excited to get the Seasonic PRIME 1300W 80+ Platinum fully modular, 135mm FDB fan w/Hybrid fan control...its quite and a dream.
I like to compare power supplies to brakes: not sexy, not flashy, you install and forget about them for a long time, but when they fail the entire car is screwed (on account of needing the nearest tree or wall to stop).
I have a corsair hx1000 I bought back in 2010 and have upgraded every part and piece but the power supply and its still running strong with good current to this day on a 11900k and a 3080. It been thru about 5 full rebuilds as I upgrade about every 2 years. Amazing psu! Good job Corsair!
I got that exact same PSU, been through several replatforms and currently running a 12600KF and 3080 hydro copper with custom water. Used to run dual 980ti's and 780's before that.
Is this still worth buying today? I was a little nervous because they're fairly old, but it looks like they're still in production and recommended in a lot of places.
I had a Corsair AX760 for a number of years, but it was not enough to handle the power spikes of my 3080Ti and I'd get random system restarts when playing certain games. I replaced it this month with an HX1000i and couldn't be happier, stability is perfect now. Definitely go high on the max wattage, it's more efficient to be closer to 50% draw at peak load anyhow.
@@The23rdGamer Hell no. The HX range has suffered from poor reliability. Obviously most of them are fine, but their failure rate is high relative to others. It is also a very old design. Power supplies designed more recently are far far better. Way better efficiency, way better response times, most are now LLC designs which is what is needed these days. You would be wayyyy better off looking at something like an RMx model from Corsair (very modern design, well made by CWT), EVGA G6 or G7 models, Seasonic Focus, Superflower Ledex models (again the more recent models).
I used a Corsair 1,000w when building my 3090 system 2 years ago. And a year later, when building my son’s 3080ti system, I used a Seasonic platinum 1,000w. My philosophy: The PS is one of the few components of a PC that could feasibly be carried into future builds for over 10+ years, so let’s make sure it has enough power for future systems, and make sure it’s quality. I also like that overpowered power supplies tend to run quiet since they’re under-stressed.
ran a 1200watt gold for years and I don't think the fan ever turned on lol.
The fan doesn't turn on.. and efficiency is less than optimal as well.
@@SupraSav that's simply not true anymore , the efficiency of modern PSUs using DC to DC conversion designs is almost flat , it is no longer a bell curve and hasn't been for around a decade.
A 1000w Platinum PSU is still going to be 98% efficient with a 50 watt load and will remain virtually identically efficient all the way through to 980 watts draw, allowing for the fact it will actively use the fan at some point.. it only drops off efficiency at the extreme low and high usage levels
So a 1000w PSU which never has to run the fan under maximum use loads around 300-500w will be about as efficient as it gets.
The new Phanteks power supplies are surprisingly good. Got a 650w 80+ Gold PSU from them for $60 on NewEgg the other day. Fully modular, hybrid, etc. Their 1000w 80+ Gold is $160.
Also worth mentioning if you upgrade your modular psu change out the cables that comes with the new one. I upgraded my psu and bricked the nice new one by trying to save time and leave my nicely managed cables 😑
I can't believe there isn't a standard for modular PSU cables yet. It's like they want us to blow up our equipment.
yeah lawgiving should enforce connector standards! 😅
@@dukex12 One of Gamers Nexus vids was with the Q/A manager for Corsair power supplies. He said that each brand can enforce pinout standards to all of their P/S component suppliers... but competing brands often do their own thing. It's starting to standardize, but there's a few outliers that insist on their own pinouts.
@@georgeerhard1949 well that's good news. Thanks for the heads up.
I remember when Modular PSUs were new. I got really excited about my PSU when that happened and I could leave so many cables in the box and not bundled inside my case.
Zenith II Extreme has 2x 8-Pin, 1x PCIe 6-Pin for OC, and for multi GPU you are encouraged to also connected the 4-Pin Molex to the bottom of the board as well.
Correction: The C Series Gold power supplies are not digital. They are traditional ones. The E Series line of power supplies from NZXT are the ones that are digital.
Seasonic or SuperFlower only for me, been running a Seasonic GX-750 for 3 years. Always check the OEM of the power supplies your looking into as they mostly don't mention it on the spec, like this NZXT C850 that has Seasonic inside.
Had no idea nzxt were using seasonic units. Got lucky at microcenter they had 750w 80+ gold units from asus for $104, looked it up, they're seasonic
I always over spec on the PSU, mainly to keep the fan from spinning up since you can't control it's speed manually.
Yep, and for coil whine aswell.
Ditto. Keep it silent/low as much as possible.
Yep, better to have 200W overhead you will never use than have your PC shutdown because you got a new hard drive.
Eh, I don't "overspec" it per se. The efficiency decreases as you go bigger
Thanks for making, yet another, brilliant video!
I'm compiling a list of components for my next PC build. The last thing is the power supply. I'm fairly certain I'll be fine with the one I'm thinking of getting, but I'll have to double check. I didn't think about modern CPUs using more power, thus needing more power cabling. It's about ten years since I build my current computer. Back then we pretty much only had to worry about wattage.
This is so true. As some one who's first real bill paying job was IT and his last real PC case and power supply was purchased back in 09. My PSU and case are still gold moving forward with my 2023 pc build.
I actually feel 20 amp receptacles are becoming more common with today's houses new and old as it's better to modernize an older house to all 20 amp receptacles but lights may be on a 15 amp depending on your lighting needs so 20 , but even then 2000w PSU you must have the newest CPU and GPU custom cooled and all your monitors connected to the receptacle to even reach 2000
It depends on where you live. NEC only requires 20A in kitchens, bathrooms, and dining rooms. Some places will install one 20A circuit in living spaces to accommodate AC units
@@xcoregamerskillz this is back in 2015 my brother was installing 20 amp circuits and in his remodeled home
Yea except converting to 20a can involve more than swapping receptacles. It may require a full rewire.
That's part of modernizing a house
If remodeling a home or room or building out a basement, I would never install 15 amp outlets; only 20 amps. It makes no sense to do so.
We need more PSU with internal monitoring via USB. One of my favorite features of all time. I'm still using my old Corsair HX850i, but they seemed to have discontinued the link feature on their newer PSU. Could you ask your Corsair rep about that next time you talk to them?
They actually make them with icue connections through a usb-c connector to an internal connector on the MB on the HX1000i and HX1500i. But they're *expensive*. I'm trying to find a rebate code to get my hands on a hx1000i, but not having much luck.
@@MichelBertrand Oh you are right, that must be fairly new. The old ones used a type of mini-usb. Hopefully they make an 12VHP version soon.
@@MichelBertrand Well they were on sale $220 and $359 at both Amazon and Corsair Black Friday through Cyber Monday week with the HX1500i as low as $340 with the 15% Black Friday coupon code at Corsair which was BF22 and CM22. CM22 is working at this moment for a 10% off either power supply. Note there is a limit of one of each model with the coupon as of this moment, one and one in your cart will work.
@@MichelBertrand CM22 for 10% right now direct from Corsair.
Also got mini usb on my AX1600i.
Nice Video Much Appreciated! Always love going through the process of how parts work and the Car analogies are Work! Hope you have a great trip! Happy Holidays
Great video, building my first gaming PC this Christmases for my kids, and this video was great for getting familiarized with PC's.
An important thing to look for when buying a PSU, is the type of capacitors. Japanese caps are longer lasting, and better quality. This make your PSU more likely to give a smoother dc output, and last longer too.
Yup, got a seasonic TX-700w 80+ titanium fanless. All japanese parts
I'm still running a massive Thermaltake 1200W PSU I bought in 2008 when I built my first custom PC. Way overkill back then, but I was young and naive. I just figured bigger number = more better. It's since powered three different PCs over the last 15 years, and is the only piece of the original build I still have.
15 years is really impressive
I recommend getting a new PSU if you’re going to build another pc and give this one a rest
I also still use my ThermalTake Toughpower 1000W I bought in 2008, was also young and thought that I would be running SLi in the near future, but never did. I am planning on mostly fully upgrading my PC next year, so it will get to retire at that point.
I remember when I bough PC Power & Cooling's first ever 500w power supply. That thing was a beast that required a special backplate as it was almost double the thickness of a normal power supply. Lasted over 12 years.
Jay. Gotta say pal. Instructional videos are amazing. Built my first pc in 2019. Built 6 more since then. Rebuilt mine countless times. I now maintain all my mates PCs. And my family's. I'm not qualified. But everything I learnt was from your videos. Massive thanks big lad. Keep it up. Love the work. Even when you take it back to basics.
I've always liked the Corsair RM850x. I have two of them and they've been rock solid and no issues. Enough power to run multi-gpu systems (I had one running three Firepro W7100's, a 3070ti, and a 1060 6gb in my small mining rig) and my main rig for many years.
Channel Well Technologies makes the RMx line
I've just bought the RM1000x and hoping its decent. I've had no issues with Corsair in the past so hoping its good, but reassuring seeing you mention them!
I like the fact that it's not that long ago that NZXT got shit on for their case catching on fire, some months later they sponsor the influencers once again.
It's been almost a year and a half, lol time flies. They did fix their H1 into the absolute perfect mini itx case. Also, they beefed up their psu's. Plus, they finally fixed their issue with not enough airflow on their cases. NZXT is like EVGA when it comes to their customers. Good brand, but they need to lower their prices a bit.
The NZXT power supplies are built by Seasonic. The same manufacterer that every company including corsair, EVGA, etc. all based their power supplies off of. There really isnt anyone better than seasonic when it comes to the power supply market. The close second would be EVGA.
@@Cloakedsphere At that price point they just *must* be better than anyone else...
God, I hate that word….influencers.
@@XiLock_Alotx agree, he's a RUclipsr, i choose whether i believe him or not, he's not trying to influence anyone, lets say, Educators instead?
EVGA SuperNova 750W gold PSUs were dirt cheap at microcenter, so I grabbed one. It works great on my 12700k + 3070 Ti machine.
Running an 8 year old BeQuiet PSU.
Haven't had an issue so far and honestly I'm impressed it still keeps working and working.
Hey Jay, it is hard to comment all videos you have, but I’ll give some words here: your videos are amazing!
You really explain things is a tech-business focus so you have helped me a lot to select the right components for my new setup.
Thank you so much for all the work and research you have put together on every video. I wish your approach of explaining things was spread out over the internet, since sometimes we don’t care a lot about very specific tech comparisons, but more along the line of the benefits that making the right decision bring.
Again, thanks for everything you have worked in your channel and keep it up!
"It will probably be the last component in your system that you upgrade." So true, the last thing I had to replace was my old EVGA 1000W PSU, and not because it stopped working, but because the fan started failing and I rather not push it with a faulty fan, other than that, having a good quality PSU is a must have, and, assuming things won't change much in the future, PSU cables rarely change, at least it didn't for the longest time until now.
Replacing that fan is probably possible, you know?
@@MoireFly Sure you can but it's generally not recommended for people to open PSUs unless they're experienced and know what they're doing. And even then you shouldn't replace a PSU fan with just any old fan as you really need one with the as close to the same specifications of startup voltage, RPM and airflow characteristics as the original fan as possible to ensure it adequately cools the components. For most people the best advice would be not to replace the fan themselves, and even if someone is capable of doing it depending on the age of the PSU they may just be better off to buy a new PSU anyway.
@@Sevicify This, I had intentions of doing so, but where I live it's hard already to find replacement parts and reading about how the fan should be as close to the original as possible; I decided it was best to get a new one, besides, that PSU served me well for 8 years.
13:28 Tbh, the safest way to do it, is to flip the switch and then click the power button for the pc to drain residual power. Reason for that, is the psu's ground cable remains plugged in, which grounds the system even when off, which helps prevent ESD damage.
Still running the Corsair TX 650 I bought in 2010, mostly powering an i52500k. It's been through maybe a dozen big power cuts, hundreds of micro-cuts, and apart from the occasional noise from the fan, is still just fine. Will definitely be changing it for my next build though.
This is a long comment that you might feel is worth reading. I have some suggestions for PSUs. Before building my new over-the-wall gamer PC, I looked at every part going into the build. I made a list of the watts that each would draw. I also added my printer and sound system, as woofers draw many watts of power, etc. These may be connected to the same outlet through a power strip. I was amazed at how many watts the finished build would need. A lot. I increased the total system wattage by 20%. This step decided the PSU watt output I would need and would prevent me from 'overtasking" the PSU. This resulted in me buying a 1200-watt instead of a 1000-watt PSU. I did this because I figured that future components would draw even more watts. A wall outlet is usually connected to other outlets meaning they are all on the same power line. If you are running other electrical devices, such as a vacuum cleaner, at the same time as your PC, you might overload the circuit and trip that breaker. This is an unintentional PC power-off condition. To prevent this, I installed a 20 amp-rated wall outlet, on its own dedicated line, in my gamer room. Another, and cheaper way, to prevent this is to install childproof plugs into all other outlets connected on the same line. This procedure will remind you to NOT use those outlets for other devices. Thank you for reading, and I hope this was helpful.
Hadn't thought of marking the plugs on that phase in some way to keep other high power appliances away from the pc. Great idea!
I went overboard for my 2600K with a a Corsair AX1200 ... my reasoning was to buy a power supply which could supply much more than ever required, meaning it was never running flat out ... still running perfectly over a decade later :)
You do know that running a system that uses a super low wattage (low compared to the PSU), is just as bad as using one that pulls near the maximum the PSU can supply... right? Look up the PSU efficiency curve for your PSU, you'll see what I mean... Best rule of thumb to maximize your PSU's longevity is to estimate the wattage your system requires (easily done with PC Part Picker), and then add 50%. That's the PSU you want.
@@matthewwalker5265correct. Ideal is matching something closer to 50% of the psu capacity - if you think you’ll upgrade to higher use then maybe 40% and grow into 50-60%
@@matthewwalker5265 the difference in efficiency at lower wattage is really minimal and makes even less difference because the wattage is so low
I have a similar power supply: AX1200i which powered at the time a brand spankin new 4930k. The system is long gone, but I still have the PSU. Reckon I could use it for a new system? (After my PC died I switched to laptop for college and stuff, but now I'm done with that I really want to switch back to PC)
On my first build around 2009 or 10, may be, I bought a 750w psu. It survived 3 upgrade. The main reason why I replaced last year on my most recent upgrade was because the fans were now noisy at full load and with the gpu I got it would probably run near full load. Currently, it’s being used on my work pc, were the psu fan doesn’t need to ramp up. So it’s been 12-13yrs and it’s still working(somewhat). Definitely worth every penny.
I think besides psu, monitor is close second on the most neglected part. Specially for first time builders.
I'm running a 750w bronze thermaltake PSU that I got back in 2011. The power switch on the back of it got jammed at one point but popping it out again and it still works like it did back then. It's been the one component that's been in every one of my PCs
The absolute "highest" for a desktop I seem to be able to get as far as I can tell in the Netherlands is the Silverstone HELA 2050 Platinum (2050w). 2nd highest are a lot more brands at 1600w.
Exactly the same here in the UK.
i never cheap out on that one cause it's a crucial part
That's pretty much the same car analogy I use. Love car analogies. No matter how much or how little someone knows about cars, they usually understand what I'm saying if I use a car analogy.
I just upgraded from a Corsair HX750 that I’d been using for a decade to a Corsair HX1200. The 750 was still running perfectly fine and whisper quiet, but figured since I was upgrading the case, MB and CPU, I may as well upgrade the PSU as well. Now I’m prepared for any behemoth GPU that may come along.
You think you are but you're not.
Another advantage a good supply has that you didn't mention is when the cheap supply 'pretty much' runs OK, but the system has random crashes you can't track down the cause of, until swapping the power supply for a better one cures the crashes (ask me how I know this...).
How do you know this?
(Followed some bracketed instructions)
Another commonly missed piece is to ensure air flow to the bottom of the case for the power supply. I have found that the large carpet sliders work out nicely giving a side benefit of easy case movement for the vacuum. Wood boards also work, but at the expense of potential splinters and toe hazard.
Small rolling moving dollys work too
If I think it’s going to be used on carpet I tend to just install it upside down. Yeah it’s pulling hot air from the inside but that’s better than no air.
5:50 European here. I remember those voltage toggles too, back in the day. However, a classmate of mine wasn't as well informed and one day in class let his curiosity get the better of him and flipped one while the PC was on. Fortunately it didn't cause any major fire or anything, but it did let out the magic smoke, and it was a quick practical lesson about electricity.
Where are days of Christmas vids??? This was always my favorite time of year on this channel
That thumbnail made me think this was some extra long PSU or sth😂
I thought it was a mouse pad
I bought a msi a1000g just because it has a 12v connector and it was only $200. I could've got the one without the 12v plug but I don't want to have to buy another one for a little while (hopefully). Also I was very surprised at how small it was, it's literally the same size as my evga 650w g5
"only" $200 - ugh, lol
"only $200" lol, yeah what a bargain!
I bought a Corsair 650W fully modular 80+ Gold PSU in 2017, and it's one of only 3 parts in my system I haven't upgraded. Plus it's still under warranty since Corsair even back then had 10 year peace of mind warranties.
back in 2014 i bought a 750w xfx fully modular psu with active PFC and 80 plus gold certified, i'm still rocking it to this day, back in the day i had a gtx 970, xfx took care of it beautifully, it's still going strong in my young brother's build, and now my xfx psu is powering my new 3070, awesome psu! too bad xfx doesn't make them anymore.
Interesting timing on this video, just as I’m considering an upgrade from 750W
honestly its more worth it to go for an 850w, especially if you want to upgrade your cpu and gpu in the future. I bought a gigabyte P850GM for $79 and other 750w psus are around the same price so it just made sense to spend 5 bucks more and have a better psu. Either way, I hope the upgrade goes well. Have a good day!
750w will safely handle anything below a 4080 and 4090 on an i7 level tdp cpu just about. Don't go crazy. My 3080ti and i7 12700k with mild overclocks or with the i7 turbo'd are under ~590w total draw
@@quantumforce4791 the PGM isn't a good PSU, even though Gigabyte re-released a "proper/fixed" unit, they're still not good, and if you have an old unit, good luck, because it's explosive... literally.
I'd much rather a 750W Revolution D.F/NZXT C *Gold* (Bronze Version has horrible coil whine)/RMX/TXM/GF1 PE/Superflow Leadex III Power Supply over an 850W PGM or 1500W crappy Aresgame PSU. Wattage does *not* define a Power Supply's performance and safety.
Keeping it simple, it's the PSU's protections (OCP OVP OTP to name a few) and if they are set to something safe that the PSU can handle or not that mainly define safety. Voltage Ripple plays a huge role as well... etc...
Not gonna explain more, but I recommend you return the PGM and buy a better Power Supply while you still can.
Just got 1000watt and you'll be good for 10 years
In today's day and age, get an 850w min. Anyone running a 3080ti + and a modern high core count should have that 850 at least. Might as well get a 1000 if you're shopping
PSU is the best part to buy even on a tight budget. Heck I just ordered a Thermaltake GF1 750W psu to replace/upgrade my stock ibuypower pre built psu which is having some issues here and there. So ya PSU is the biggest investment. :)
Good choice 👍
@Blueberry thanks. :)
Not sure how you qualify a fast depreciating asset as an investment
kermit sips tea.
This current rig of mine was originally 'overspecced' regarding the PSU, with a 750W Gold EVGA for a i7-6700k + GTX 970.
Yet it ended up being fine, and allowed me to effortlessly swap in an RX6800, and now, ~7 years after original assembly, an r5 5600.
Certainly a very nice realisation when I was looking for a GPU upgrade.
The only downside is that the extra cables were lost at some point, when the box with stuff went 'somewhere'.
Was fun getting a SATA SSD daisy chained with the hard drive.
HUGE THANK YOU FOR THIS!!! I watched this video just in time....well...slightly late but not too late.
I was so busy concentrating on calculating my PSU needs for my build, Gold rating and ARGB capability, I never even thought to see if the ports were compatible with my motherboard and GPU...I just assumed it was standard....they were not! I had ordered a Thermaltake, which I now got refunded and returned, but the big thing was I had cablemod custom cables ordered....and you only have 24 hours to cancel the order!!!
Got the cancelation in in 20 hour mark!!! So now I'm going with the NZXT C750.....wish it came with RGB, but they have no models for that. More important it has 2 8pin CPU and 2 8pin PCIe ports.
NZXT seems to be out of stock in a lot of products, but found one on Amazon which I just ordered. THANK YOU AGAIN!
Not related but I would love to see a video showing how different monitor setups, monitor size, number of displays and resolutions effect gpu load👍
its only the resolution and number of monitors that effect gpu not the size of a monitor
the only part that can brick an entire system, never cheap out on psu
Scary I was thinking of what new psu I was thinking of getting and this video popped up, 😳 thanks for the vid Jay
The J2C iFixit ad should win an award!, I've seen it 100 times and it still cracks me up.
PSU's definitely don't get the love they deserve, I remember building one of my first PCs and the PSU was always an afterthought, I recall looking at £15 500W PSUs (the ones that last 6 months before giving up), it wasn't until I'd been metaphorically burned that I started looking into it much more and 80 Plus Bronze become my standard go to. As I started being able to afford higher quality stuff my PSUs went up in rating and wattage. My current setups use a budget Corsair 750W Bronze with a Focus Plus Gold 850W in my overclocked 8600K rig, which is hugely overkill but it'll be a super simple transplant into a future 13th Gen Intel or new Ryzen update.
1000W PSUs are around $210 here in the UK so I'll need to start saving before upgrading as the PSU price increase means that even my Focus Plus Gold is selling for more than I bought it for 4 years ago.
My current power supply (750w Fatality) is at least 10 years old. It has been through multiple upgrades, but it still works great. I'm planning on getting a replacement for it when it does eventually either die or need to be updated. Luckily (??) I cannot afford current-gen hardware, so it still works pretty well, but I dream of eventual upgrades that will draw more power...
When it dies, you better hope it doesn't take out other components with itself. My uncle's 2010 build nearly went up in flames in 2017 from a leaking cap in the PSU. I seriously recommend upgrading your PSU ASAP so it doesn't blow up. That unit seems to be decent compared to many other units from 2013. I'd say older PSUs can get a good 7-8 years of life on average; despite it being a good unit, I still recommend upgrading it now.
I've never had one die on my quite that badly, but maybe I'm just lucky. Typically, they simply refuse to power back on
Hoping my 850W is enough for my 7950X and (upcoming) 7900XTX. Was looking for 1000W but the deals were wayyyy better with the 850.
It's a Seasonic prime GX so hopefully it's got good capacitors for gpu transient spikes.
got evga gold rated 1300 watt for $170 in amazon pre black friday sale for the new gen ddr5 set up.
850 watts is plenty and you can likely get away with just 750 watts. Component makers will over-estimate the wattage requirements just to be extra safe people aren't gonna have random crashes or shutdowns due to power starvation. Use a Kill-A-Watt meter or something like that to measure your total system draw from the wall and you'll see that your system consumes way less than you thought it did.
@@DesuVR Except that's false, due to spikes in wattage in new generation hardware you should generally get 50-100 Watts more than the recommended Wattage, also for extra components.
@@flintfrommother3gaming good power supplies will handle spikes and exceed their rated power without trippin OCP. My asus thor 850w can handle 1200w for a few milliseconds during a spike
That's plenty, especially for the reference 7900 XTX but yeah those transients could pose an issue with AIB cards if they push it with 3x8 pins. However, that's what the reviews are for - to help purchasing decisions lol.
Back when I first built my PC in late 2015 I used an EVGA 650w Supernova. I remember over-specing it because I planned to go SLI (but never did). I finally replaced it in 2022 because, after upgrading to a 3070, it would pop the AFCI breakers in my apartment for some reason. It's still going strong, though, I have it in my server now and plan to replace it when it dies.
i bought a 1300w g2 evga back in 2014-2015 and was running sli at the time. serves me well. have no issues and its still running like a champ. tho might soon have to upgrade it for the new connectors and such.
A lot of mainland Europe is 220V/230V using the 16A Type F schuko plug design with a max draw of 3680W, whereas in the UK is 230V/240V using the 3 pin 13A fused plugs which is where the confusion comes from as both is used in Europe. The max wattage we can pull in the UK from a single wall socket is 2990W on 13A at 230V.
Great info, Jay, thanks a lot!
Few things I didn't know. Now I do thanks to you 👍
Been watching your videos everyday, im new to PCs and ive learned so much watching your content and i LOVE it keep it up boss!
I built my first system 10 months ago and used an EVGA 750 gold. So far it’s been great. Currently running a 4070ti and a 5800x3d, and it’s been holding up quite well.
Thanks for covering this vital component, often taken for granted but never willing to concede its importance.
Gone are the days where PCMag or someone else thoroughly covered the "lowly PS". Their tests from 10+ years ago showed all sorts of data, none of which is available in today's reviews. I suppose the manufacturer might furnish such upon request, but even that is unlikely.
For several years systems required less power than previous versions, but that day too is gone. With top CPUs in the 250+ watt range, GPUs in the 600+ watt range (each), and who knows what else will become far more power hungry, it is no surprise that 1000+ watt PS will become typical. That juice has to come from somewhere, and there's no substitute for the PS to furnish it.
I recall your recommendations regarding how much margin one should allow for a build, and in some I disagreed for one reason. Good PS will provide quite good to best efficiency in the middle third - i.e. 33% to 67% of rated wattage - of their range. For reasons of better warranties, better ripple, adequate margin regardless of expected future additions, and just like having something I can expect to depend on for a long time, I stay in that middle third.
Somehow this reminds me of the age-old question regarding "which camera should I buy". The pros always answered "buy the best glass you can afford".
Again, thanks.
Missed the chance about ATX 3.0. I think now is a good time to warn people about waiting to buy PSU's since there's just so few with the 16 pin gpu connector and the ones that are out there are still super expensive!
It might be useful to address UPS differences and the fact that hungrier systems now may be pulling more than a UPS is rated or able to supply. Along with the benefits of power conditioning that they can bring etc. Another overlooked but actually kinda important component.
Eaton 5px , Ion 16, apc smart, no need to get double conversion unless you into 5kva plus . As they switch less than 6ms and psu must cope with upto 20ms dropout
I bought an EVGA T2 1000W Titanium like 9 years ago. Still using it on my 3rd build now with a 13900K and 4090. Probably my best PC component investment.
Sage advice. Back in the mid 90's when I built my first computer I didn't place much importance on the PSU. Not long after I finished the build I was playing Microsoft Indy Car racing and the PSU started smoking and the entire system shut down. Not only did it shut down but it destroyed every component in there. I basically had to start over from scratch. SCSI drives and controllers were expensive. Lol. Ever since then I don't cheap out on power supplies.
I love that we're discussing power and the electrical receptacle behind Jay has no trim plate on it. Safety first!
my current PSU is a 11 year old 1100 watt PSU.. got the thing on sale on newegg back in the day.. even then was like $150 but was a great investment.. it has gone through legit 4 PC builds in its 5th build now and just keeps on going. run it through a PSU tester every so often and checks out everytime.. go big on the PSU will save you money in the long run.. aside note my PSU has something called active phase control or something like that and may be the big factor into why my PSU has last so long.. remember the psu I had before getting it legit blew up thus why I got this one
I bought my EVGA 1000w platinum PSU in 2015, has a ten year warranty. I know I should get a new one soon but this thing has been kicking butt the whole time I've had it. Glad EVGA is still around to at least sell PSU's cause they are one company I know I can trust.
Probably a Superflower Ledex model. Slightly out of date as not LLC, but other than that they are legendary for build quality and reliablity.
My first Sandy Bridge build in 2012-the Core i5-2500k, Sapphire Radeon HD 7970 (believe it or not, blower-style, lol), 8GB Kingston HyperX Blue 1600Mhz DDR3 RAM, and a Asus P8Z68 V-Pro/Gen3 Modo, all coupled with an NZXT 850W PSU, and it went like all hell for a solid 5 years!
I am currently using a Pc Power and Cooling Silencer 750 watt 60 amp 12v rail supply that I purchased back in 2007!! Its running a ryzen 5600x , 16gb of 3600mhz ram, 6700XT, 1tb nvme, and 2 2tb western digital blacks.And 6 120 mm fans. Its never skipped a beat in all these years.. I take it apart and blow it out once in awhile, and look for bulging caps, and test the rails with my multimeter, its always dead nuts on.
This might be the most densely packed video, information wise, Ive seen in a while. Good job guys!
dude i fix it ads by Jay and his crew is just amazing! im on repeat on the ad section LMAO
I look you out for parts bro. Thank you for making it your grind.
I lived in the Philippines for almost 5 years (2016-2021) and it was disturbing how it was hard to get a decent power supply there. Only the really premium shops had them, at that they still offered some crap PSUs. I still saw the AT standard for sale, complete with daisy chain power plug for the monitor. Most there won't believe me when I tell them it's not worth it to cheap out on that one component, especially how the 240v system there fluctuates as much as it does.
And.....to this day the 9900k I built there with an SFX Seasonic PSU still runs till this day, even after bringing that machine back stateside.
I bought a Corsair AX860i, I think during the SeaSonic times, and that thing's still going strong today with a 5600x and a 3070, been the PSU I've used since 2012 or so, I love that thing. After 11 years, thinking this year is the year I buy a new case and new PSU.
That Corsair 1200W Platinum I bought for my 4790k is still running well. My 5700X arrives to finish my replacement build tomorrow. The LAST thing I ever worry about is my PSU. Not been so confident on that part for twenty years.
