Just wanted to ask but do the power supply cables used for testing matter? I didn't see Patrick swap out the cables for the ones that are included with the EVGA power supply. Are they interchangeable with the Gigabyte ones? Thanks!
@@MegumiKato. Modular power supply cables are not typically interchangeable, and even if you can plug them into different PSUs, you shouldn't. You can actually damage your components if you try to do that. I know some people who have killed some SSDs doing this. I'm assuming that Patrick prepped their testing equipment with EVGA cables prior to filming to save time.
@@konga382 Indeed, that is the exact reason why I asked. It was a single cut wherein Steve brought in a brand new EVGA power supply with Patrick in the middle of swapping out the fuse in the test equipment. I did not see the cables being swapped out from the testing equipment and I was just curious about it since I had the impression that they just got a brand new, yet to be unboxed unit, for testing.
I'd like to see the same tests run on a Corsair RM-750x, just cause it seems to be a PSU that a lot of people have, and I think many would like to see how it behaves in these situations. Perhaps you could do a "grab bag" style video (or most likely series) where you bring in some of the most popular power supplies, and put them through your OPP cycle, just to showcase how various non-explosive PSUs handle overloads.
PLEASE give the camera operator at 4:20 a raise.....they actually increased the shutter speed to match the frequency of the tester's display refresh rate and actually lowered the ISO or increased the F-stop to compensate for the increased exposer. Not many camera operators pay attention to that kind of detail, even on "professional" channels.
He'll let go if the company involved behaves responsibly. Gigabyte did not, so he's ramping up the pressure so that there's no excuses left for Gigabyte.
Gigabyte deserves this 'grilling', especially after they tried to blame their problems on the reviewers testing, rather than just owning their mistake and fixing it...
@@EminemLovesGrapes Because massive companies do not care until most of the public is voicing complaints so smaller infulences have to repeat themselves when they find an issue. Gigabyte has idiots defending them just like Blizzard does, just less because they don't make interactive products.

@@igameidoresearchtoo6511 No, modern GPUs are way more "spiky" with their power consumption. Maybe just for a few ms, but they can go way above their normal power usage.

To be fair, Gigabyte have made some good PSUs in the past, and I've used other stuff made by them (mostly motherboards) fairly reliably. The big problem here is that they aren't seriously acknowledging the problem these PSUs have. With this sort of corporate attitude, I'd be very hesitant to buy anything Gigabyte right now.
decade old PSUs might win "better than gigabyte" and in those days PSUs were considered part of case purchase and came pre-installed . even they didnt explode this much
@@rodh1404 true, with this new MSI type attitude. it'll be difficult to choose their product going forward. Mayeb some MSI officials moved to Gigabyte and started their cost cutting games
I think some of the first gen Super Nova PSUs from EVGA did actually have some serious problems, but, to my knowledge, EVGA didn't try to pretend that its products were fine, and handled the situation a lot better than how Gigabyte is handling things now.
I've had an EVGA 750 G2 for years (can't even remember how many) through multiple system rebuilds, and plenty of overclocking, it's been rock solid. I'm glad to hear they continue to deliver good stuff.
I have exactly the same model. I bought it because it had a 9.8/10 score from Johny Guru, and was available for a good price, and it had a 10 year warranty. Your power supply is probably still under warranty even now.
850 G2 that i got for free after doing some work for a family friend because they spilled a drink in it. I replaced a capacitor and it's been going strong since.
That’s funny: I was choosing exactly between those two 750W PSU’s in January :) Thanks God I chose the EVGA one! Thanks for such a good investigative videos!
Owner of a 5 year old EVGA Supernova 750w and its put up with every upgrade I've thrown at it to power; all the way up to a Ryzen 2600X and Sapphire Nitro+ Radeon 5700XT, an armload of SSD and HDD totaling about 12 terabytes, 32 gigs of ram, and 7 fans ranging from 140mm to 200mm. If I ever upgrade that power supply it's going to be a EVGA Supernova 1000w because my trust in them is rock solid
I think that sums it up really well. I only use cheap PSUs because I trust that even they were designed by real engineers who did their best so that the PSU fails safely and correctly when (NOT IF with PSUs) something goes wrong. (Never been disappointed by the way, even the ones that failed did so safely and for legit reasons.) That Gigabyte thinks its fine if their fairly expensive by my standards PSU fails destructively and incorrectly as long as it is outside normal use parameters is just incomprehensible to me.
No, no, no, you see, it's a feature of our power supplies. Permanent Over Power Protection, or as we like to call it, POP! for short. This feature alerts the user in a quite audible and visible manner when it's been tripped thus letting the user know that it's time for their regularly scheduled RMA process to begin. ~Gigabyte (probably)
Power supplies don't get the love they deserve. The most important part of any system is relegated to a boring "box of electronics". So kudos to Gigabyte for bringing them into focus.
Great video you guys! I'm personally running a Corsair RM750x psu in my system and had it for about 4 months now and it is great, no issues so far. I've heard of companies like Seasonic, EVGA, and Be Quiet who supposedly make great psu's. I cannot vouche on behalf of those companies but as for Corsair psu's, so far so good. Keep up these great and informative videos @GN
Gotta say, I really enjoy this 'discussion' style of video. It's nice to have Steve talking directly to me, but I've always enjoyed listening to two enthusiasts enthuse together.
I have no interest in a psu atm, but i love the investigative journalism, thank you to all the gn team involved, i watched the full video, and never skipped the ad;) Thank you for going on principal to such lenth to show us the issues
I was ordering a build for a friend, saw a deal on the EVGA 750 GT SuperNova and was wondering if it's good. Came across the title in this video and just smashed the order button :D
EVGA does change their PSU partners like people changing their underwear though. So it's a mixed bag of bad, decent, and good units depending on the model. I think there are like... 10+ different G series 80+ gold PSUs under EVGA now...with the best being G2, G3, and the new G6.
@@GPSaBu yep. G6>G2>G3>GT>G+>G5>GA>GQ>GD G6: good Seasonic unit. G2: good Superflower unit. G3: decent Superflower unit, some had protection issues. Loud at high load. GT: decent HEC unit. G+: FSP built ACRF unit. Inferior to well designed LLC resonant units. G5: FSP built ACRF unit. A good bit worse than tye G+. GA: Andyson built LLC resonant PSU with some problems. GQ: FSP built ACRF unit. Mediocre performance, lacks a MOV. GD: meh. Don't remember who built it. Might be an FSP ACRF unit. Worse than the bronze rated B5.
@@GPSaBu indeed. I got a G3 and it has worked perfectly for years. I went through a phase when I tried overclocking and tripped the opp a few times (which was good). It is still in my rig working just fine.
I would add a bit on the "Seasonic" part is that they have been consistently putting out good PSU's that, whenever independently tested and analyzed, do work well and as advertised or better. Sure, Seasonic can produce a lemon, but based on years upon years of their PSU's building up a good reputation, chances are lower. And if they do indeed make a lemon, it is more plausible they will act on it to keep intact the goodwill they garner from their reputation, as that alone will keep driving them sales for free.
I agree, their reputation is PSUs not a generic brand for bought in back end stuff so they have to look after their name. I have been impressed with the Corsair PSUs but Seasonic would get the nod too. I still have a Dong Fung PSU ( Aywun) that came with a case and it will never be used in anything I build. Any company that tries to brazen out of its failure is not due much respect. Any brand can have failures but it's what they do about it like apologising and replacing it without quibble rather than blaming the messenger or saying flat out it was misused as a first response.
@@RonanLamour HIgh-end Corsair are Seasonic. But the most most people are buying (the average range ones) are Superflower. Also many EVGA units (like the one in the video) are Superflower.
@@kaldo_kaldo Except that there are several ranges at Super Flower and we know that the top of the range of Super Flower is much more reliable than the top of the range Seasonic
The fact that the fuse in the tester didn't blow (reading were still on the display), means your mobo, graphics card, processor and SSD aren't going to damaged by this EVGA PSU. Compare that with the gigabyte PSU, which clearly sent something nasty to the tester as it died.
I'm actually enjoying this series because Stone is so chill as he runs these tests. These are way more entertaining than any electronic testing videos have any right to be.
Lol love the end and this is why this is my favorite review outlet the honesty from all of you at GN. Thanks for showing us both sides of the PSU testing.
I think when this saga is all over we need a playlist for this so we have an easy way to remind companies what happens when they do something like this
Companies really are pretty stupid when they deny things. Everyone knows "drama" attracts multiples more attention than an average positive review. Product passes - people see it, they discuss Test fails - more people see it, more discussions on what the problem can be, but it's still not that bad. Deny the failed test and mounting evidence of a true problem? - that's how you go "viral".
Hey Steve, can you do a video with all the staff members where everyone tells a little bit of background about them? And also what they currently do in GN? I especially want to know about the Patricks, cause I always mix them up.
Hoping to! Haha, it'll likely be on a side channel but we will promote it via the GN Community Page once we do one. Need to get through some backlogged content.
And will Gigabyte learn something or two based on seeing these results? Probably not. (Which is pretty low considering how a Dell OEM unit still manages to pass :/)
Dell has the whole system on their warranty so it makes sense they would try pretty hard to make sure they don't have to take the entire PC. Still, Dell can price it out gigabyte should be able
Just - Thank you for what you do! You are not trying to bring down a company or anything. You are just looking out for every day people! I hope everyone understands that. I think if Gigabyte acknowledges the issue and recalls the PSUs, story is over. This wont not have even reached here if they didn't give out a cocky response to a scientific yet standard testing. Great job !
Really happy with my EVGA PSUs. Have had a 1300 watt supernova G2 for 8 years and still going strong. Just replaced it with a new 1000 watt supernova for a new build just because of age but it is certainly not retired. Glad to see these working how they should and thanks for these videos.
Really appreciate you doing this vid. While it was obvious how the other one failed, it's nice to have context for how a properly functioning PSU works.
18:00 "You know, EVGA you're hurting my channel performance right now with your functioning power supply." I'm dead, lol. I've used the same EVGA Nex750B for 2 builds and have had zero issues with explosions. My name just happens to be a pleasant coincidence.
Oh snap, I actually picked up this PSU for my first ever PC build in December and was worried the video was going to show it failing as well, so glad to see I made a good choice with this one!
@@jtsyo8364 wrong. Some of them were reported to be dead on arrival. I sure as fuck wouldn’t be trusting my expensive ass pc to a power supply that doesn’t perform how it’s supposed too. Accepting this shit from companies is why so many shit companies are still around. If we as customers are going to buy something we shouldn’t expect mediocrity.
How amazing. GN team knew it's gonna be a boring video but they did it because viewers asked for it. Thanks Steve! And thanks for the whole team. Now back to you Steve!
evga is actually cool tho. even when they're 3090s were getting bricked, they immediately replaced any bricked units. super cool of them to do that and it shows how companies should handle issues with their products
@@supervillain3213 not really the games fault when the fan controller things it should run at 230000rpm and burns itself to death. Its a problem reproducible in other games as well btw. New world only made the problem more noticeable due to no framlititer in the loading the screen but its not their fault
I feel like when you were talking about how to buy PSUs in your "Just Buy Seasonic" section was to also mention most PSU brands dont make the PSUs, like EVGA does not make power supplies, that they are made by delta/seasonic/greatwall/fsp or whomever (dont know who makes 750 gt supernova)
GIgabyte does get say into the components used - which obviously has an effect. So yes, the manufacturer (like EVGA) of the power supply does matter even if they don't technically build them. If Gigabyte used Seasonic, for example, and directed Seasonic to use crap components you are going to get a crap power supply. Steve covered this exact topic in the 30 minute gigabyte fail video too.
Excellent educational content! We learned a whole lot about how power supplies are supposed to work, and we learned that Gigabyte deserves the derision they have attracted. Keep up the good work!
I see nothing wrong with the Gigabyte's approach, their application of POPp Permanent Over Power protection, which includes audible and visual indicators, seems to be an effective approach. The ability of the Gigabyte PSU to alert external agencies (fire fighters) when it activates when unattended could be a positive benefit? Perhaps other manufacturers might have already looked into POPping their PSU but found that the negative feedback to the Gigabyte approach was too large an overhead.
When you act like the US government and deny a problem exists, and people's lives/property is at stake, there's a serious problem and they need to be held accountable for their actions.
I love how you guys are dragging gigabyte though the mud again and again and again and again and again and again and again, oh by the way did you mention the gigabyte exploding PSU's ?
I love it - fair warning to all power supply manufacturers: if you ship a crap product there will be no quarter! People get lazy/stupid when they think no one is watching. Gamers Nexus is doing the entire community a huge service with this level of testing/evaluation.
We can see how much of an engineer's heart Patrick Stone has when he calls the power supply "lovely". That's an adjective you don't expect for a power supply
Imagine how salty Gigabyte must be that EVGA beat them to registering the trademark for their GP-P750M namesake... "The other guys might CALL thier PSU a SuperNova, but only Gigabyte brings your the real thing!"
I gotta laugh at how you guys keep poking Gigabyte. This is exactly what happens when you don't own your mistake and instead attack the media that did everything to help you make a good PR and product move. This whole thing should serve as a business case study on how you *don't* respond to an issue in a product. Gigabyte has done everything wrong.
Someone please get that man a GPIB interface (or equivalent) for that tester! Using a stopwatch for this kind of test has been obsolete back in the '80s. Also, if the variac fuses are getting damaged when they blow you should look into using the opaque fuses filled with sand. The sand extinguishes the arc so they can interrupt a lot more current safely.
I have an EVGA SuperNova NEX750B. I've had it for about 4 years now and it's been awesome. Definitely not the most expensive PSU but it hasn't made me question its reliability.
I'm so glad that i "settled" for the EVGA SuperNova 850W GA psu when I upgraded my PC about 6 weeks ago!!! Thank you very much for your continued honest work in reviewing products unbiased!
I really like Patrick Stone's presence and interaction/chemistry between Steve and him. He's the 'Anthony' _(from LTT)_ of Gamers Nexus, heh. I mean this in a very positive way _(love seeing Anthony's videos)._ His past really shows, the teaching aspect. That formality and structured way of speaking comes through. Really love it.
Anthony has a much better voice (dude can sound like a trailer announcer with very little effort), but Stone is really good at making in-depth technical stuff like this sound genuinely interesting.
I've used at least 10 of the EVGA 750 GA Supernova 80+ Gold in builds I've done for customers and no issues at all. EVGA is easily one of the best power supplies on the market.
@Ethereal Audio I would go with the EVGA all day, myself. Not saying there's anything wrong with Cooler Master, just personally prefer EVGA since I've never had an issue with their product.
GN is my go to honest and upfront review channel. The effort u guys put into gathering data and showcasing it in a comprehensive manner is a huge attraction for me and the reason why I watch ur channel. Any possibility to run a PSU review on the corsair sf750? Planning a build here using it hence ur honest thoughts would be great on it.
the "just buy Seasonic" point was for the vast majority of consumers who are not going to plough through 20 PSU reviews, research what makes a good PSU and what doesn't, and just want something that works. If you're going to roll the dice on a brand/manufacturer, you're far better off with a reputable OEM like Seasonic/Superflower/FSP etc.... than companies that just rebadge PSUs
@@siripfreely Anecdotal evidence obviously but I’m having to rma a 750w platinum corsair psu due to horrible coil whine any time the gpu gets loaded up. I’ve torn out the 750w evga out of my old system which works perfectly. Plus the fact that the corsair unit has bloody caps in the modular cables means I’m gonna push for a refund instead of replacement. This is a brand new psu too so I guess I’m just unlucky. Saying that I’ve had a seasonic unit that failed within its 5 year warranty also.
One thing about Seasonic is that, unlike Corsair, you generally don’t hear people saying “those are fine but don’t get ** model”. Seems that even the lower end Seasonic models are not particularly bad at least.
Seasonic warranty is really good. I bought an Amazon Warehouse used/returned power supply and it was faulty. I don't live in USA and shipping back the faulty one would cost a lot. Seasonic sent me a new one direct to my country and paid the shipping cost, without requiring me to send in the faulty one. The only requirement being I remove and cut up the label with the serial number, remove the warranty sticker, and send them a photo of it. The whole process was pain free. They did not ask me a set of stupid questions or try to insinuate that I am doing something wrong.
That's... a lot of testing, they just started with PSUs. We'll get there eventually, but I wouldn't count on it for this year. A good thing is that PSUs stick around for longer periods than other PC components, so their testing will keep being relevant for a longer time
OK, so I have a question. I remember PSUs having a better performance curve (more efficient) when running at 240V, vs running at 120v. After seeing little RMA reports in Europe for those Gigabyte PSUs, my question is, how do they perform on 240v? have you guys checked them?
For a pure power perspective, as you increase the voltage used, the more efficient your system will be. This can be seen in industrial power lines that run at 10 kVolts. Current is the bigger issue as more current correlates to more voltage loss. Say we have a 1000 W power supply. One at 120 V, the other at 240 V. Also let's throw in 10 kV for fun. Let's assume 2 ohms of resistance. P = V * I. V = I * R. P = I^2 * R. This is for total power (S), not counting imaginary or Real power here, though it is Real since not using capacitance or inductance at all. 120 V: 1000 W / 120 V = 8.33 A. 8.33 A * 2 = 16.66 Vloss. 16.66 Vloss * 8.33 A = 138.78 Wloss. 240 V: 1000 W / 240 V = 4.17 A. 4.17 A * 2 = 8.33 Vloss. 8.33 Vloss * 8.33 A = 69.39 Wloss. 10 kV: 1000 W / 10 kV = 0.1 A. 0.1 A * 2 = 0.2 Vloss. 0.2 Vloss * 0.1 A = 0.02 Wloss. As you can see, we lost 69.39 Wloss for the 120 V rail...while 10 kV was basically nothing. That's why powerline are so high. Of course this is an extremely simple example. A real power supply will have to account for capacitance and inductance, smoothing out the PWM signal from the controller IC and ripple, using a feedback loop to cut out current transients, accounting for power loss in the switching mosfets, and much more fun things. I encountered some of that in my university capstone with a power supply company. Also answered here: www.quora.com/Why-is-a-device-with-a-higher-voltage-and-a-lower-current-more-efficient btw fun fact, DC power lines would be more efficient once a certain amount of power line miles have been crossed.
These two videos have been amazing, thanks for the effort. I haven't seen a PSU fail like the gigabyte in over 20 years, how they could claim it was anywhere near acceptable is crazy. Curious, outside of the Gigabyte model (sorry, couldn't help the extra dig at it), have you ever run OPP testing on an otherwise reliable unit repeatedly to locate a terminal failure point, if it has one?
Since Johnny Guru i have not seen anyone put the level of detail in with oscilliscope graphs and frequency analysis, etc that he did. He was the best, and that was how i chose my next few PSU's was based on his data. Its all about the data...
We decided to cut off testing around the 30-minute mark since it was still running without issue at that point, whereas we could kill 2-3 GBT PSUs in that same time. For those of you asking what's supposed to happen, hopefully this helps! Feel free to leave more requests below!

Anything wrong with the AresGame ones? I got one running in an older sidebuild, 500W one, and its been fine for now. Its only a 4690k/gtx680, so not being stressed too much.

@@igameidoresearchtoo6511 No, modern GPUs are way more "spiky" with their power consumption. Maybe just for a few ms, but they can go way above their normal power usage.

Makes me think you need a "Well, it's better than Gigabyte" award for you power supply tests. :D
Lol "better than Gigabyte" means nothing, even a bad PSU which doesn't explode is better than Gigabyte :D
Well that reward would be on 99.99999% of all power supplies.
To be fair, Gigabyte have made some good PSUs in the past, and I've used other stuff made by them (mostly motherboards) fairly reliably. The big problem here is that they aren't seriously acknowledging the problem these PSUs have. With this sort of corporate attitude, I'd be very hesitant to buy anything Gigabyte right now.
decade old PSUs might win "better than gigabyte" and in those days PSUs were considered part of case purchase and came pre-installed . even they didnt explode this much

Gigabyte: EVGA had some False Advertisement with the “Super Nova” PSU
i'm dyiNG
@@Zi7ar21 See you on the other side
“Some PSU sellers”
That's all right. They can just brand it "The Lightning".
I think some of the first gen Super Nova PSUs from EVGA did actually have some serious problems, but, to my knowledge, EVGA didn't try to pretend that its products were fine, and handled the situation a lot better than how Gigabyte is handling things now.
I've had an EVGA 750 G2 for years (can't even remember how many) through multiple system rebuilds, and plenty of overclocking, it's been rock solid. I'm glad to hear they continue to deliver good stuff.
I have exactly the same model. I bought it because it had a 9.8/10 score from Johny Guru, and was available for a good price, and it had a 10 year warranty. Your power supply is probably still under warranty even now.
I have a EVGA 750 G5 Supernova. It's not as old as the G2 but I've had no issues thus far, a year and a half into its lifespan
Same. Been using for 8 years and recently replaced my gpu with a 3080. Still rock solid.
I just got a 1600 T2, looking forward to getting many years of good use out of it.

Thanks God I chose the EVGA one! Thanks for such a good investigative videos!
You dodged a bullet on that one! 😅
Owner of a 5 year old EVGA Supernova 750w and its put up with every upgrade I've thrown at it to power; all the way up to a Ryzen 2600X and Sapphire Nitro+ Radeon 5700XT, an armload of SSD and HDD totaling about 12 terabytes, 32 gigs of ram, and 7 fans ranging from 140mm to 200mm.
If I ever upgrade that power supply it's going to be a EVGA Supernova 1000w because my trust in them is rock solid
"Power supplies that are well designed will not explode" That made me laugh more than it should have.
Can I just say, your cameraman does really good work with focusing on and showing things while you're explaining them.
Gigabyte: What is your opinion of our PSUs with OPP?
Steve and Patrick: We think it would be a good idea.
I think that sums it up really well. I only use cheap PSUs because I trust that even they were designed by real engineers who did their best so that the PSU fails safely and correctly when (NOT IF with PSUs) something goes wrong. (Never been disappointed by the way, even the ones that failed did so safely and for legit reasons.) That Gigabyte thinks its fine if their fairly expensive by my standards PSU fails destructively and incorrectly as long as it is outside normal use parameters is just incomprehensible to me.
No, no, no, you see, it's a feature of our power supplies. Permanent Over Power Protection, or as we like to call it, POP! for short. This feature alerts the user in a quite audible and visible manner when it's been tripped thus letting the user know that it's time for their regularly scheduled RMA process to begin.

You forgot the "We take pride in our power supply design." and "Gigabyte is trusted by millions of customers worldwide."
Power supplies don't get the love they deserve. The most important part of any system is relegated to a boring "box of electronics". So kudos to Gigabyte for bringing them into focus.

Can't agree more, having a good quality PSU is so underrated. The basis of any trouble free and stable system.
Thanks for running a test with a normal power supply. Theory is great, but seeing it work practically makes the point completely clear.
Great video you guys! I'm personally running a Corsair RM750x psu in my system and had it for about 4 months now and it is great, no issues so far. I've heard of companies like Seasonic, EVGA, and Be Quiet who supposedly make great psu's. I cannot vouche on behalf of those companies but as for Corsair psu's, so far so good. Keep up these great and informative videos @GN
Gotta say, I really enjoy this 'discussion' style of video. It's nice to have Steve talking directly to me, but I've always enjoyed listening to two enthusiasts enthuse together.
I have no interest in a psu atm, but i love the investigative journalism, thank you to all the gn team involved, i watched the full video, and never skipped the ad;)
Thank you for going on principal to such lenth to show us the issues
Glad you're still on Gigabyte, glad this story isn't just disappearing
I was ordering a build for a friend, saw a deal on the EVGA 750 GT SuperNova and was wondering if it's good. Came across the title in this video and just smashed the order button :D
Not gonna lie, this makes me feel better about the evga power supply I have in my main rig. It's not the same one, but this is still reassuring
EVGA does change their PSU partners like people changing their underwear though. So it's a mixed bag of bad, decent, and good units depending on the model. I think there are like... 10+ different G series 80+ gold PSUs under EVGA now...with the best being G2, G3, and the new G6.

@@siripfreely How about GM?
I would add a bit on the "Seasonic" part is that they have been consistently putting out good PSU's that, whenever independently tested and analyzed, do work well and as advertised or better. Sure, Seasonic can produce a lemon, but based on years upon years of their PSU's building up a good reputation, chances are lower. And if they do indeed make a lemon, it is more plausible they will act on it to keep intact the goodwill they garner from their reputation, as that alone will keep driving them sales for free.
Not to mention that all Seasonic Prime Series power supplies have a 12-year warranty (some evga too but that's pretty much it)
They have 3 independent psu testing facilities verify performance. On every line.
Corsair and evga both are seasonic
I agree, their reputation is PSUs not a generic brand for bought in back end stuff so they have to look after their name. I have been impressed with the Corsair PSUs but Seasonic would get the nod too. I still have a Dong Fung PSU ( Aywun) that came with a case and it will never be used in anything I build. Any company that tries to brazen out of its failure is not due much respect. Any brand can have failures but it's what they do about it like apologising and replacing it without quibble rather than blaming the messenger or saying flat out it was misused as a first response.
@@RonanLamour HIgh-end Corsair are Seasonic. But the most most people are buying (the average range ones) are Superflower. Also many EVGA units (like the one in the video) are Superflower.
@@kaldo_kaldo Except that there are several ranges at Super Flower and we know that the top of the range of Super Flower is much more reliable than the top of the range Seasonic
The fact that the fuse in the tester didn't blow (reading were still on the display), means your mobo, graphics card, processor and SSD aren't going to damaged by this EVGA PSU. Compare that with the gigabyte PSU, which clearly sent something nasty to the tester as it died.
The explosion in the Gigabyte PSUs is a result of a clean short, so the tester "only" sees a massive spike in current draw. Fuses are good 🙏
As the owner of a EVGA 750w Supernova that's around 5 years old now, this just makes me even happier with my choice

Companies really are pretty stupid when they deny things. Everyone knows "drama" attracts multiples more attention than an average positive review.

Test fails - more people see it, more discussions on what the problem can be, but it's still not that bad.
Deny the failed test and mounting evidence of a true problem? - that's how you go "viral".
Some say that "any publicity is good publicity"

Probably not. (Which is pretty low considering how a Dell OEM unit still manages to pass :/)
Do you want some guarantees with that?
Dell has the whole system on their warranty so it makes sense they would try pretty hard to make sure they don't have to take the entire PC. Still, Dell can price it out gigabyte should be able
Wasn't the Dell PSU a re-fitted server part? Aka a part you REALLY don't want to blow.
Would love to see a post mortem on the failed supplies to show exactly what types of components failed and the possible reasons they did fail.
they did that in their first video though.
Just - Thank you for what you do! You are not trying to bring down a company or anything. You are just looking out for every day people! I hope everyone understands that. I think if Gigabyte acknowledges the issue and recalls the PSUs, story is over. This wont not have even reached here if they didn't give out a cocky response to a scientific yet standard testing. Great job !
Really happy with my EVGA PSUs. Have had a 1300 watt supernova G2 for 8 years and still going strong. Just replaced it with a new 1000 watt supernova for a new build just because of age but it is certainly not retired. Glad to see these working how they should and thanks for these videos.
Really appreciate you doing this vid. While it was obvious how the other one failed, it's nice to have context for how a properly functioning PSU works.

I guess Permanent OPP is a pretty good name for Gigabytes "feature": If it doesn't like your power consumption, it will go POPP!
I feel like when you were talking about how to buy PSUs in your "Just Buy Seasonic" section was to also mention most PSU brands dont make the PSUs, like EVGA does not make power supplies, that they are made by delta/seasonic/greatwall/fsp or whomever (dont know who makes 750 gt supernova)
GIgabyte does get say into the components used - which obviously has an effect. So yes, the manufacturer (like EVGA) of the power supply does matter even if they don't technically build them. If Gigabyte used Seasonic, for example, and directed Seasonic to use crap components you are going to get a crap power supply.
Steve covered this exact topic in the 30 minute gigabyte fail video too.
Excellent educational content! We learned a whole lot about how power supplies are supposed to work, and we learned that Gigabyte deserves the derision they have attracted. Keep up the good work!
In a fab that I worked at, there was always a spec limit and a control limit within that spec limit. We always stayed within that control limit.

Hi!
Just to say, I have an EVGA 650 GQ in my PC since 2018 and it still works fine !
Even it experienced multiple bad shutdowns (power outages)
I see nothing wrong with the Gigabyte's approach, their application of POPp Permanent Over Power protection, which includes audible and visual indicators, seems to be an effective approach. The ability of the Gigabyte PSU to alert external agencies (fire fighters) when it activates when unattended could be a positive benefit? Perhaps other manufacturers might have already looked into POPping their PSU but found that the negative feedback to the Gigabyte approach was too large an overhead.

Imagine how salty Gigabyte must be that EVGA beat them to registering the trademark for their GP-P750M namesake... "The other guys might CALL thier PSU a SuperNova, but only Gigabyte brings your the real thing!"
I gotta laugh at how you guys keep poking Gigabyte. This is exactly what happens when you don't own your mistake and instead attack the media that did everything to help you make a good PR and product move.
This whole thing should serve as a business case study on how you *don't* respond to an issue in a product. Gigabyte has done everything wrong.
Someone please get that man a GPIB interface (or equivalent) for that tester! Using a stopwatch for this kind of test has been obsolete back in the '80s.
Also, if the variac fuses are getting damaged when they blow you should look into using the opaque fuses filled with sand. The sand extinguishes the arc so they can interrupt a lot more current safely.

@@siripfreely Anecdotal evidence obviously but I’m having to rma a 750w platinum corsair psu due to horrible coil whine any time the gpu gets loaded up. I’ve torn out the 750w evga out of my old system which works perfectly. Plus the fact that the corsair unit has bloody caps in the modular cables means I’m gonna push for a refund instead of replacement. This is a brand new psu too so I guess I’m just unlucky. Saying that I’ve had a seasonic unit that failed within its 5 year warranty also.
One thing about Seasonic is that, unlike Corsair, you generally don’t hear people saying “those are fine but don’t get ** model”. Seems that even the lower end Seasonic models are not particularly bad at least.
"Yeah our power supplies POPPed. Here at Gigabyte, Permanent OverPower Protection isn't just some empty acronym."
Seasonic warranty is really good. I bought an Amazon Warehouse used/returned power supply and it was faulty. I don't live in USA and shipping back the faulty one would cost a lot. Seasonic sent me a new one direct to my country and paid the shipping cost, without requiring me to send in the faulty one. The only requirement being I remove and cut up the label with the serial number, remove the warranty sticker, and send them a photo of it. The whole process was pain free. They did not ask me a set of stupid questions or try to insinuate that I am doing something wrong.
Thats how you guarantee your future brand, customer, reputation.
Given your testing methodology, I would like to see a round-up of GN's recommended PSU for a given price point close to Black Friday.
That's... a lot of testing, they just started with PSUs. We'll get there eventually, but I wouldn't count on it for this year. A good thing is that PSUs stick around for longer periods than other PC components, so their testing will keep being relevant for a longer time
Seconded!
Thanks Steve! Appreciate GN for taking the time to do this comparison. Arguably pointless but I'd like to see gigabyte call out the testing again :)
OK, so I have a question.
I remember PSUs having a better performance curve (more efficient) when running at 240V, vs running at 120v.
After seeing little RMA reports in Europe for those Gigabyte PSUs, my question is, how do they perform on 240v? have you guys checked them?
Maybe they arent sold here so often (i haven't checked)
I believe those PSUs mainly sell on newegg bundled with graphics cards, and newegg doesn't ship to most european countries
For a pure power perspective, as you increase the voltage used, the more efficient your system will be. This can be seen in industrial power lines that run at 10 kVolts. Current is the bigger issue as more current correlates to more voltage loss.
Say we have a 1000 W power supply. One at 120 V, the other at 240 V. Also let's throw in 10 kV for fun. Let's assume 2 ohms of resistance.
P = V * I. V = I * R. P = I^2 * R. This is for total power (S), not counting imaginary or Real power here, though it is Real since not using capacitance or inductance at all.
120 V: 1000 W / 120 V = 8.33 A. 8.33 A * 2 = 16.66 Vloss. 16.66 Vloss * 8.33 A = 138.78 Wloss.
240 V: 1000 W / 240 V = 4.17 A. 4.17 A * 2 = 8.33 Vloss. 8.33 Vloss * 8.33 A = 69.39 Wloss.
10 kV: 1000 W / 10 kV = 0.1 A. 0.1 A * 2 = 0.2 Vloss. 0.2 Vloss * 0.1 A = 0.02 Wloss.
As you can see, we lost 69.39 Wloss for the 120 V rail...while 10 kV was basically nothing. That's why powerline are so high. Of course this is an extremely simple example. A real power supply will have to account for capacitance and inductance, smoothing out the PWM signal from the controller IC and ripple, using a feedback loop to cut out current transients, accounting for power loss in the switching mosfets, and much more fun things. I encountered some of that in my university capstone with a power supply company.

btw fun fact, DC power lines would be more efficient once a certain amount of power line miles have been crossed.
@@SuperSSSSooonniicccc putting 2ohms of resistance to get 69 Wloss.
NICE
These two videos have been amazing, thanks for the effort.
I haven't seen a PSU fail like the gigabyte in over 20 years, how they could claim it was anywhere near acceptable is crazy.
Curious, outside of the Gigabyte model (sorry, couldn't help the extra dig at it), have you ever run OPP testing on an otherwise reliable unit repeatedly to locate a terminal failure point, if it has one?
Since Johnny Guru i have not seen anyone put the level of detail in with oscilliscope graphs and frequency analysis, etc that he did. He was the best, and that was how i chose my next few PSU's was based on his data. Its all about the data...
We expect there will be more tech journalists like you GN guys, with healthy mentality and great logic. Amen.
