Power supply wattage show how much it can output, not consume. So if your power supply is not 80 PLUS Titanium, you not overload it
Good video! I actually had my first power related issue this week, couldn't boot despite having a 500W PSU and all the parts being under that requirement. New GPU? Fixed the issue! GPU worked in another pc with a power wattage PSU. Crazy times! Great video though, really glad someone other than me put their parts at risk to find out what happens 😁
isnt that so frustrating when all the parts work on different systems but not together!?
I've just run into this issue. Replaced a GTX 960 with a RTX 3060TI OC and when I ran a benchmark test on it, the PC shut down with a 630w PSU, which is a little over 12 years old at this point (go Raidmax! ;) ).
I tried reducing the GPU clock speed, but it didn't help. Headed out to pick up a Corsair 750w. Hopefully, that fixes it. Thanks for the demo!! :)
Same for me, finally replacing my 600W Raidmax with an 850W Corsair! That little green cobra did its job for 8 years.
Reading this is making me sad ... I have a Ryzen 7 7800x3d and I'm replacing my RX 6800 with a RTX 4080 and was hoping I didn't have to replace my PSU, but looks like I'm going to need to. 750 watts currently
@@KitsuneCieli would go for at least 850 or 1000 watts pairing a 7800X3D with an RTX 4080. It leaves more headroom for future upgrades. There are good 1000W PSU’s under $150, I found one from be quiet!
@@Datsun7705 going with a 1000w PSU, since I decided on the RX 7900 XTX since I picked on up for around 850 after tax.
@@Datsun7705 didn't really fell like changing, since one im lazy and 2 just bought it xd
Thanks! Super helpful just wanted to make sure I'm not gonna fry my computer when I put my new parts in if the PSU is not quite enough. Didn't know about the power supply calculators either, really helpful information!
i'm just now arguing with a guy that insists it's a waste to buy "more than you need" and says that it's okay to load your psu to the brink while GAMING. the guy isn't even thinking about full load, he says you should just see what your pc uses during game and buy a tight fit for that.
ugh.
i mean, you still shouldn't buy a 1000W PSU for an r3 and 1050ti. just calc needed power on any PSU calculator and add 50-75W more to this
Bomb has been planted..... 😂
😂
Fun video,
Any power supply worth its salt shoud shut down well before it burns or causes damage to any components.
As it has been for years dont trust the psu label theres alot of cheep power supplies with ocp turnd off or set way to high as well as dangerous levels of ripple and voltage over/undershoot.
The best place to find info on psus quick and easy would be the latest psu tier list thread on ltt fourms.
Yes. This is by no means a comprehensive buyers guide, just an experiment one what happens if you way over do it. I have definitely had my fair share of high wattage power supplies that simply didn't hold up.
psu is actually alot interesting to me, and that's why i search for videos like this one, Thank you for the explanation video
But you didn't actually exceed the power supply's rated power draw. If you took 660 W from the wall and the psu efficiency is 85% it means its actual output was 660*0.85=561 W. It was running fine and well below maximum.
Rated psu power is the output power! Depending on efficiency the psu will pull more from the wall.
I'm running a 5700x3d and 5700 xt with 64gb ram and a few SSDs and HDDs. Powered by a 450w corsair PSU.
some games pull 425W consistently, and every now and then the pc shuts down without warning. When I run prime95 and furmark it hits 550W while the CPU and GPU are both undervolted. I'm sure it could reach 600w at stock voltage. It crashes after about 30 seconds at 550W.
New PSU is being ordered lol.
would have been nice to see a power supply tester and see whether the voltages remained a) the same, b) within spec
I just blew up my hp psu server 1200w and i have no idea why it can happen. I'm surely check all the component (mining rig) doesn't surpass 1200w because it's only 3xRX5700 (maybe the whole system just draw 500-600 watt). My question is..are psu server with breakoutboard dont have any safety feature like atx?and what kind of mistake that make psu end up exploding like a firecracker if its not caused by overload?
Sorry for my bad english btw
And keep up the good content like this 👌
My PSU blew because i forgot to switch it from 110V to 250V lmao
I bought a 450w for a i5 3470 and planning to add a gpu, but then I remembered that the psu bought has no pcie cables I should have picked a 500w for future upgrades. Lol
Also don't buy sketchy psu
@@HoodedStatue oh, so the 1500w psu for 25$ on wish isn't okay, you say?
@Jan if I want to be lit on fire, Yes
Good video. Any power supply if in an overload condition would go into an over current condition and due to the circuit of the power supply should shut down automatically. These are factored in the design.
So two days in a row my PC restarted on its own. 2 times it happened while playing MW3 warzone. Once was on the desk top when I opened Steam. System is a 5800X3D, GPU is a 6950Xt. PSU is an 850W gold. Something is going on but I dont know what. I monitor the Temps and the temps all appear to be pretty Low… any thoughts? 850w “should” be enough for the system… but maybe its not?
Thank you for this video, I just saw this behavior with my system, I can confidently say my psu is insufficient
If you shorted out the power supply, would it just explode or catch on fire?
ive shorted my power supply it will just turn off for a couple of minutes and turn on again if its a good psu,if its bad boom boom
I have a question...
I upgraded my GPU and I can play for hour or so and then suddenly game crashes and PC reboots...
Is that PSU??
Blows the powersupply internal fuse.
Oh, now i know, why the us had rolling blackouts recently..... ;)
NIce testbench and WOW, the adapters are madness! :D
Haha yes I may have had something to do with those blackouts
As the time of writing this comment there is a strong storm here in the Philippines
@@HoodedStatue im sorry for that, germany had insane weather in the last 2 weeks, flooding whole districts and such. Hope you're all okay over there.
need 1000w power...make sure to buy 1800w for safe use in the long term
AMD A8-9600 RADEON R7, 10 COMPUTE CORES 4C+6G 3.10 GHz running windows 11 - 2x 1gb hard drive + 1 gb ssd + 2 cd rom is my 600w supply enough ?
Did you see a dip in performance ?
Hey! i wanted to get a GTX 1070 and i have a 300 watt psu and on neweggs psu calculator thing it says it goes over 300 watts by just 1 watt...so i wanted to know if my computer would be fine with that.
For the GTX cards I'd try to get a 450/500W. I have a 500w EVGA Bronze 80+ and I have had 0 power issues on my 1070 Ti / AMD Ryzen 5 2600 65W
For everyone wondering, NO DONT, i have problems now because of 300w. I'm using 1070 with i5 7400 and it's just shutdown under load. 1070 while clocking at 1900mz uses just too much power... According to some sites, this setup can use up to 380watt...
i have gtx 1660 super .. its enough 500w powersuplly or not
So in otherwords i should be good only starting the windows to test my rx 6900 xt with 600w to see if it works
The lights in my room started to flicker and my psu started buzzing
That's just the gamer energy absorbing into your body for max gaming performance, you're the chosen one.
I hope ur still responding. Today i plugged in a 20pin PSU in my oem 14 pin mobo. pins aligned but no post and pop. psu fried
>Me after running my i7-4770cpu with a 3060 at 4k on dead island 2 ultra settings with a similar setup and smelling the stickers on my power supply melting before it just turns off
Bottleneck..
Please for the love of god DO NOT cheap out on your power supply guys! power supply or PSU is the MOST important part of your PC! a cheap PSU doesnt care that you have a 4090 or intel i12. it will destroy it!! when shopping for power supply check reviews find out if a specific psu is reliable or not if psu costs close to $200 take it your paying for insurance. if your really unsure what to get ask a store to help you find the right one dont just connect a $50 one you found on wish! steer clear of that!
where i live u can get one 80+ bronze :)) or silver :)) with that money.
I used a 450w supply, pairing with a 1080ti and 860k.
Hiw
Hi, My PC recently wont boot up. After switching on, it immediately switches off automatically.. 6 month old build.
Psu Rm850w corsair
Cpu i9 12900K
Mobo Rog Z690 maximus hero
Gpu RTX 3080 ti Oc
Could it be my PSU ? Or something else.. every component is 6 months old
Are you sure you have enough power for that build?
@@stonalisa3729 all sorted, at the time I was not using surge protectors. And the motherboard got an over current or something..
i have gtx 1660 super .. its enough 500w powersuplly or not
i have 690watt gpu with 850 80gold psu, it is safe?
I'm trying to figure out the same thing(not same amount tho). You got the answer?
hey can i use a antec vp 450p plus 80+ white psu (V3000A200H-18) with rx6600
CPU Ryzen 4350g
