Speedrun Gigabyte Power Supply Explosion: Biggest Failure Yet (GP-P750GM)
HTML-код
- Опубликовано: 3 июл 2024
- Gigabyte kept claiming that media testing was over "extended time periods," so we decided to speedrun the explosion of one of its GP-P750GM PSUs to prove a point.
Sponsor: Buy Corsair's 5000D Airflow Case on Amazon (geni.us/cnVP60)
For context, here's how the PSU is supposed to work: • Gigabyte, This is How ...
THERE ARE ZERO CUTS IN THIS VIDEO BEFORE THE PSU FAILS. This is a single-take, one-shot speedrun to challenge Gigabyte's statements that third-party media testing was over "extended" periods of time, as Gigabyte tried to paint testing in the light of being ridiculous. The problem remains the same: Aris of Hardware Busters (Cybenetics) thinks that the MOSFETs are mistimed, and we agree. They're also not particularly good quality, and tend to go boom and hit runaway thermal scenarios (if not design faults first). OPP trips or not, we believe the Gigabyte GP-P750GM is poorly designed. The GP-P850GM has also had similar failures in our testing.

I shall. Once I have the money. I know it's 100% worth the buy!!
Just throwing this out there but would it maybe be prudent to use a PSU from another company in the same wattage/price range go through the exact same testing just to show that a properly built PSU can handle exactly what just killed that Gigabyte one.
@@Ravendarat They did that in the first video covering these power supplies. They covered multiple competing models that all turned off with OPP without exploding
@@faceplants2 Oh perfect, somehow I missed that. Thank You!!
TY for your consumer advocacy.
Gigabyte be like: but the PSU was used for 600 years before you did the single cut
Hate when that happens.
I thought the same thing. GN should have started with a new, in-box PSU to prove that it hadn't been abused before testing.
@@Okusar If it works when they plug it in, it should remain working. Or, OPP should work as intended and shut it down before it explodes.
If it explodes, it's a bad unit regardless
Yeah totally unfair they used a psu that has been used once out of the box before rather than using a brand new unit from the factory.
What? Does he think the normal consumer uses the same psu for more than 2 days?
Inb4 Gigabyte demands that you use a specific PSU from a specific lot that was wiped clean before testing and was fed only the choicest AC wall power from a socket manufactured in...

It would be great to see you guys demonstrate the exact same test conditions with a seasonic or similar psu to show what should happen, that in turn would prove its not your test that’s the problem. Great work guys.
Just that with a good PSU, nothing happens. But a test where nothing happens isn't a proof. That's looking at a murderer when the murderer doesn't murder anyone. That would not prove it isn't a murderer.
@@perwestermark8920???
@@johannespeeters7368 It means just what I'm saying. With a good PSU, the PSU will shut off when it reaches the protection limit. Then it will start again after you remove the overload and cycle power. Rinse and repeat and all you see is still a working PSU.
To make it meaningful, they would need to make a *real* time laps where they continue this cycle hundreds or thousands of times just to show that it works, and stays working.
It's easy to demonstrate broken equipment just because you can capture the failure. But how to capture a non-failure? When is enough enough?
If we were talking about PSU without protection, a good or bad unit could be demonstrated by showing the amount of safety margin. But when the tested PSU have overload protection, you can't. Except to show what happens when the overload protection does *not* work. As in this specific case.
So it's bit like "how to prove you do *not* beat your wife"...
@@perwestermark8920 i think your metaphors need some work but i get that you cant keep doing it but the point is just to show what happens normally and that doesnt need to be done a lot(just like an hour) . Even if its as unimpressive as just shutting off.
@@johannespeeters7368 They have already shown Gigabyte PSU *not* failing. Because not every of the Gigabyte PSU ends up exploding.
Just that at least two have ended with something broken when it reached the overload condition and have then given an explosive failure when restarted at 60% load. I.e. the overload protection circuit itself does not cut off the load in a safe way - something breaks (not always, but often) when the overload circuit trigs.
It behaves a bit like when you cut the power to an inductor without any freewheel diode - the magnetic energy ends up inducing a large voltage that kills the transistor that disconnected the power. So the turn off looks ok - but next turn on will show the result of the zapped transistor.

I really wanna see Steve run the All MOSFETs category now
Damn. You beat me to it. XD

This will now spark a competitive speedrun category and lead to the shortage of these units as everyone tries to get a wr. I am expecting the price of these to skyrocket as times get more and more competitive while the supply drops. Then desperate speedrunners will beg gigabyte "will you please, please, please make more of these?" but the hardcore community will reject anything but the original series and it will lead to leaderboard splitting.
Spark competition, I see what you did there. 😉😉
i was thinking about submitting a run to the "any% ignition" ladder but now im thinking the real competition will be in the max% category where we see how much of the unit can be melted and the timer stops when the flames go out

Insightful: 60% load after successful OPP = plasma arc / soiled underwear / DOA / no RMA. Good to know. Gigabyte crossed off my build-list. Thank you!

A "pre-emptive explosion" is the equivalent of "You can't fire me, I quit!"

I knew that boom was coming with all the headphone warning signs but it still startled me
I was shocked at how load it was too.
Yooo dapz
I was actually in time to turn down the volume. But then the message disappeared and I thought I'd missed it so I turned up the volume again. I think I need new pants too...
They should've added a timer instead of having the message disappear thinking we're in the clear.

I love that this thumbnail FEELS clickbaity but is, in fact, 100% representative of just how bad this issue is. 😂
This is why GN is the best testing channel, if there's an issue, they put in a fuckton of effort to prove it and show that the companies are truly BSing us.
(also hi badseed love your videos)
It's reverse clickbait. It baits you in and completely delivers.
Oh man, you're a fan of GN too? BadSeed + TechJesus collab when? xD
sometimes things are that representative :D
I xp'ed that some years ago with a 500w psu. Loud bang and it tripped the circuit breaker. This was night time, so sitting in complete blackness and smelling burnt electronics was not fun.
Seeing him put his hand directly on the power supply while the headphone warning was on screen is the tensest I've felt watching this channel.
This video is a titan-class power move, holy shit. Mad props to you guys for giving Gigabyte a massive slap to the face that they very much deserve.
shout-out to the camera guy at 3:15 who probably went "i've got to fix my shutter speed ASAP" and did so flawlessly 👍
or the zero flinch from the explosion. just a couple smooth steps back.
: D this guys is nut. Running 750w psu at more than 1050w! Of cause will explode lah omg ? Which means we can set opp at 5000w & see then. See whether msi psu will explode on 5000w opp then 😁🤔🤔.......,,,,
@@roxy_xcxc6869 i don't think gigabyte understands why they actually need "protection" with overpower protection
@@roxy_xcxc6869 the point is that if i did the same test on a seasonic PSU, it would shut down safely every single time.
@@roxy_xcxc6869 The PSU is supposed to shut itself off before damage occurs. If the PSU stays at high enough load to cause damage before hitting OPP, that's Gigabyte's fault for shipping the PSU with such configuration.
At no point do I recall GN modifying OPP; OPP was set by Gigabyte. GN was only simulating a high load at the power output.
Up next from Gigabyte: "questionable media outlet improperly tested our high quality PSU by not installing it atop the insulation pads. As explained by the verge pc guy."
Tweezers (zipties) were not used in the test and the fan was not suffocated, verge pc tester at gigabyte headquarters clearly demonstrates this is a completely incorrect usage scenario
The verge guy would probably think the power supply is a battery
@@DatGamingKid1 "some pc batteries can be expensive, but I bought this 10 million watt battery from Amazon for $5, you can choose what you use though'
Just hammer it in there.
You make them sound like the Chinese Communist Party...
Steve: "this video is brought to you by Corsair"
Gigabyte: "Heeeeyyyy"
"It's almost like gigabyte uses DC Electronic load testers in it's factory", that would explain why there have been so many DOA power supplies, gigabyte have already conducted "repeatly" the OPP trip tests "for an extended period" using a "DC electronic load"
Exactly. The blatant stubbornness in their reply to GN is astounding for such a large company that previously had a good rep. They are just shooting themselves in the foot.
@@addictedtoRS They didn't have a good rep though, even going back decades. The name Gigabyte represents poor QC and failing products.
@@trevc yep can confirm, i had a gigabyte motherboard 19 years ago it failed after couple of months of use, all i did was play call of duty 1 and battlefield 1942, unsure what it was but whatever happened it fried, i still remember the smell i was only 13 at the time so i had nfi lol ever since then never touched that brand again.
@@trevc eh. they weren't perfect but they weren't exactly ECS - who is still around and making garbage. Anecdotes mean both very little (to others) and a whole ton (to yourself, if it's your anecdote) but I always held them a rung higher than e.g. Zotac or MSI (baffles me that they're popular now - they were _garbage_ when I got into this hobby) but just a hair under ASUS. "ASRock tier" or "ASUS's board was out of stock/too expensive/missing a feature" tier. And there were "better" companies that are either no longer around, or no longer making consumer, gamer, or US market hardware: e.g. DFI, EPoX, SOYO.
I think I've had more Gigabyte video cards than any other manufacturer, except for XFX in recent years. No issues with a single one of them. Bought a lot of three used ones with one DOA that I realized had clearly been used for mining after receiving it - two of them had the _wrong_ vBIOS on them, wrong DRAM type. They RMA'd it no questions asked...although I did manage to reflash the proper factory vBIOS on it first by sticking it in a machine with a working GPU. Feel _significantly_ less guilty about that now after learning how slimy they are.
My Gigabyte Z68 board is to date the only motherboard I've ever had fail on me, after ~5 years of running it overclocked, and I don't fault it entirely since the HX620 that was running it went kaboom a few months before that. After seeing this, I am now wondering if the _motherboard_ took the PSU out pre-emptively, lol. Replaced it with a beat up ASUS Z77 board and realized what I was missing. I had tons of BIOS and POST issues with the Gigabyte board from day one, overclocked or not. I dialed the same exact overclock into the replacement board and then _went even higher_ and its rock solid. Long live Ivy Bridge. Ivy Bridge is dead.
@@noxide23use 5600 with gigabyte s2h and x570 gaming X all fine
A part of me hopes Gigabyte keeps denying the need for a general recall, so that GN will keep making savage PSU video's.
And so that a more formal recall may be in order. I love when companies are forced into doing the right thing, rather than being able to deny, deny, deny and then let up at the last second and call themselves the good guy.
I have been watching videos recently, by two guys who have lived there for more than a decade, about China. Culturally Taiwan is part of China. The problem is, they just psychologically can't assign blame or take responsibility, unless forced. This is the same with Thermaltake's bad case designs. Nobody is allowed to say that there is a problem. The guy who designed this thing, and possibly the guy who hired him, is already gone.
If gigabyte keeps denying GN should take a bunch of the same PSUs and make them race each other to death.

Next Gigabyte press release: “Media outfits promoted an unintended use of our high quality power supply, which is orienting it in vertical fashion.”
The classic Apple method of "You're holding it wrong". It wouldn't surprise me at all if they did this.
"We take these problems extremely seriously. Thus, we have concluded that all of our buyers are in extreme need of education on avoiding tripping the high OPP of the PSU."
You mean like in a lot of modern PC cases? 🤔😅
They'll say that running the PSU at over 50% is bad
"plus... the members of this media outfit had their tongue in the wrong position in their mouth. That can make the PSU explode. Yeah you can make a lot of things explode. PLUS... if you hold one toe up while pushing the other toe down, you can also make the PSU explode"
I had my PSU (seasonic 750 titanium) going in short circuit protection under certain loads because (after weeks of trying figuring it out blaming bios settings, LLC voltages, usb devices etc... The pc just turned off sometimes after hours, sometimes never, often while alt tabbing with many things open like discord, game, overlays etc...) a naked metal inductor of the vrm was touching one screw of the monoblock... It saved all the pc at least 10 times before I could figure it out the real problem.
Then there are PSU like this.
I wanted to say when seeing this video: Seasonic is the Bentley of Power Supplies! I'm unwilling to use anything else.
Safety glasses are highly recommended in working with exploding stuff. Otherwise, damn good job guys. Thanks for everything.
Some say that the fireworks that lit up the sky on the evening of the Fourth of July were actually a series of Gigabyte PSUs exploding simultaneously.

Praise the camera man ! I love how he noticed the 7 segments display flickering and quickly adjusted the camera shutter speed for our greatest pleasure. Good quality video as always !
Not that many people even know how to deal with multiplexed displays like that, much less have the camera to compensate for something like that.
I noticed that as well.
For the Emperor!
Kept on the subject while sorting it out, too!

The way Steve smiles at the beginning, his eyes really sparkled like the P750 when it exploded.
I'd love to see a real-time repeat of this test with a comparable known good PSU so we can directly see what the expected behavior is. Loving this kind of in-depth content, keep up the great work :)
... Nothing would happen with a real PSU
I've seen a lot of people say this in the comment but the PSU would just... turn back on like normal. Ideally you'd be able to repeat this test multiple times without failure as OPP should be tripping before the PSU is actually damaged. They even said in the video many of the PSUs were failing when the brought them back up to OPP, not when they were turned on to normal loads.
well your request has been granted.
they did the same thing with a brand new PSU from EVGA, that came straight out of the box.
spoiler: it didn't explode... as you'd expect

I own one of these that is within the serial number range they posted, and I want to sincerely thank you for the head's up on the potential failure probability. It prompted me to replace it before a failure, and might just have saved my components. Both Newegg and Gigabyte have been responsive to my inquiries into the "return and replace" mentioned in the Gigabyte press release. Hopefully I will get a correctly working PSU shortly.

I pulled this same PSU from my daughter's gaming PC this weekend. The Gigabyte PSU was part of the NewEgg shuffle for an RTX 3070. I'm hoping GN's investigation will lead to a recall and a refund.
Doubt. Gigabyte is way too cheap and Chinese HQd to get anything done. Not in a discriminatory way, following in MSIs footsteps (although they are Taiwanese) by never admitting negligence. And their US offices can't do shit right now.
I got one with my gpu from the shuffle as well. Glad I never opened it up. ^^
Same here. Except I saw the issue videos before the psu was deployed. It’s still in the original plastic wrap on a shelf. Not sure if it works or not. Or even what the serial number is. Worst case I make it a bench top psu for hobby electronic projects where I don’t care if I blows up.
Wise choice

I can't imagine what crosses the minds of these companies when they see a GN expose and are just like "Double down! He'll back off!"
Out of touch PR people. Speaking as someone who has worked in fortune 500 companies, the people who decide on the response are generally in their late 40s and 50s and are completely out of touch with the new age mentality. Most old timers in these companies think they can lie their way out of incompetence and the "system" will protect them...because most of the time it does.
"In real-world, no one is going to use their PSU in the way that they have tested. Therefore, all the Newegg and Amazon reviews saying this PSU blows up are false. We will process the returns."
Also Gigabyte: "Serial numbers don't help cus I can't read."

They look badly behaving multi million/billion dollar companies straight in the eyes, kick them in the balls, and then absolutely destroy them when they keep up with their b.s.
the entire industry fears this man
What's even greater is he clearly shows they aren't just putting massive load on one connector.
He's showing they opened up some of these PSUs to figure out the rails and created loads for every single rail in the PSU separately, by connecting all the necessary cables to all rails.
That's dedicated and perfect methodology.
There are a couple of problems with Steve's testing.
(A) Firstly he loaded this PSU for a prolonged time above its rated power. You might think that 2-5 minutes is short time but it actually is very long time in relative terms. These power supplies are not designed to expect a sustained load above their rated value but instead they are only expecting brief spikes. Spikes can be created because of inductors, etc and they only last a few ms. So although during their service life these PSUs may see the power shooting momentarily to 1000W or 1200W they are definitely not designed to see the load remaining there for seconds let alone minutes. That is hundreds of thousands of times longer time than expected.
(B) More importantly when the failure occurred he essentially had a big step-function current (or equivalently power) draw. The load went from 0W to 450W in a microsecond. Such high current slew rates (rate of increase of current) are incredibly damaging to the components of the PSU. In real PCs, both the motherboards and the add-in parts (GPUs, etc) are designed in a way that limit the current slew rate to exactly avoid such step functions which can lead to a catastrophic failure. What Steve and Patrick should have done was to ramp up the current/power in smaller increments or use an inrush current limiter (which can simply be a thermistor) between the load and the power supply.
So yeah Gigabyte is absolutely right on this one. Not saying that there aren't other design issues on Gigabyte's PSUs that can lead to catastrophic failure but Gamers Nexus' methodology (especially the huge current slew rate) is just way too brutal. ATX PC power supplies are simply not designed or validated for such a DC Load Step Response.
I'm waiting for the Blue Origin style infographic showing that his shop doesn't really exist and his stuff is unsafe.
When he put PSU sideways I was thinking of those mines with label "towards your enemy" for direction of the blast :D

Dude, thank you for this video! you stopped me from buying a Gigabyte PSU, now I get why they are priced to be such a good deal!
Finished my first PC build back in March, uses Seasonic for the PSU (after a bit of research on the internet)
And this is why people should do some research rather than choosing 'brand'.
Thank you for making the video, great job as always
So nerve-racking watching this video. Every time Stone put his hand near that power supply I was like, "Noooooooooooo!"
I about had a heart attack when I saw him holding an "exploded" PSU in his hand waving it around, until I realized that was the "fresh" one that is next up for the executioner's block.
And then I stroked out when he went back and ripped open the exploded one in the same take. He's for sure WAAAY smarter than me about this stuff so I'm sure it was really fine, but I didn't see/know whatever happens to super make sure capacitors are grounded out. .... or maybe it was just a "yolo, don't touch the deranged innards" and trusting yourself not to fuck up.
Not the left hand please, please have a habit of touching electronics with the right hand. (Electrocuted pathway)
Especially many times he covered the fan with his hand.

I just replaced my faulty, old PSU. It was triggering some protection (Current, power, thermal idk) every time I loaded a heavy gaming scene, making my entire PC shutdown instantly and restart. Unsure what the problem was, I thought it was my mixed RAM at first, I did a lot of testing and used my PC for a week or 2/3 in this state for work and lighter games. It crashed like two dozen times before I replaced the PSU to find that that was the fix.
Now just imagine I had a PSU with a fault like this. I could've blown my entire PC. It's just insulting to see Gigabyte denying there is a serious problem here.
And btw I almost actually bought a GP-P750GM as replacement, but didn't because it had low user reviews. So thanks reviewers.
“Can I get you to touch this capacitor?” Should be a GamerNexus shirt.

Or: "It's not even over 9000!"
So, because you use an electronic load, would this be considered a Tool-Assisted Speedrun(TAS)?
Nope, as they need a load it is seen as necessary equipment. As you need some sort of controller/mouse/keyboard to speedrun a game.
I mean, sure, since Gigabyte sure seems to be acting like a whole bag of em!
It would've been TAS if they pre-programmed the sequence of actions into their testing device and executed it with a single "start" button.

Might be a dumb question but if that testing machine is drawing power from the psu what does it do with all those Watts? does it just heat up?

@@EpicGamingEct Clearly you didn’t see the part where the PSU literally blew up
says the company that DOESN'T SEAL THEIR BOXES
My wife bought a gigabyte P750GM a year ago for a system she built.
This weekend it blew up. We thought maybe dust bunny shorted out something so we ran some air through it visually inspected, didn't see any blown caps or magic blue smoke burn marks.
I found this video today after I tried to test her PSU with a PS tester (no load just voltage check) and hitting the switch resulted in an immediate arc in the PSU.
Put her SSD in an old system of mine so we know they survived, but don't know yet about her GPU, CPU, MB, or RAM. I have a known good PSU (EVGA 850) to test with. Fingers crossed it didn't nuke anything else.
Just the intro alone had me in stitches!!!! Nice one Steve.
Oh Gigabyte is going to nail you for using a variac, they will claim it supplies an in consistant variable voltage that the PSU is not made for and that is the cause for failure they won't say anything about it galvanicly isolating the PSU making it safer..... Watch for it to hit the next press release, they will say anything they can to sidestep this clear bugger up that they made... Just an FYI, A DC electronic load can be a PC a laptop or a DC motor....... A load is a load, wether it be a PC or a damn resistor...... It's a frikken load..... Just own it Gigabyte you messed up.... OH! and testing to OPP boxing it up and giving it to a customer having it DOA.... Nice Gigabyte....
Years ago, I worked in a factory that built large back up power supplies. The test phase of the bigger ones were run at 100% load for eight hours then, iirc, 125% for 4. The entire factory would be in the low 100s (degrees Fahrenheit) that morning. For some clarity, they would run these things starting on a Friday and ending Monday morning around 4am. The worst part was when one would fail a Hi-pot test. That little flare from that 750w power supply is nothing compared to liquified 1/2” bus bars and 3-6” plasma flares. The smell of the other fried components was atrocious.
I guess the point of all that was the testing they did wasn’t considered complete unless the units could put up with the worst the end user could throw at them and then some.
Clearly, this manufacturer has a design/component/quality control/budget issue. It would seem that their language in their reaction would indicate that they know it.
IF they perform any QC to begin with..if
Kind of reminds me of another "Gigabyte-explosion": I used a beQuiet! power supply on my Gigabyte G1 build couple years ago (Z97 G1 + 980ti G1). The caps on the mainboard exploded and the G1 burned to a crisp - will never forget that smell. Once the cooling was removed, I gently blew some air over the nvidia board: some burnt ICs simply dissolved into dust. They just disappeared from the board. The power supply is still kickin' though, as is the mainboard. Replaced the fried crisp 980ti with an RTX OC on second PCIe. That smell though...my my...
@@matthausadamitz2127 Yeah, the stuff you from that can stain your sinuses for about a week. It’s awesome, especially the 3rd time.
This testing to 100% load applies to a lot of things. Even some engineers don't know that critical components can be and in some cases should be tested to 100% load befpre being put to use. Not to just test as a sample. This could be mechanical parts like suspension parts of a racecar, cable ties, welds or joins between different materials for example.
Some people also think testing is somehow always destructive. It isn't. Testing at 100% load is not the load at which the thing should break anyways. It is the maximum which the part should handle without issues. More to the point, everything is designed with a safety margin. Elevator cables for example have a safety factor of 11. That means it needs to be able to handle 11x the maximum design load. Most of the time the safety factor is 2 or 3 for most parts. However things should always work at 100% load and not break. Be that 100% load a weight, amperage, watts, torque, heat or speed.

In a nutshell when both mosfets are conducting at the same time it's a short circuit. One mosfet must turn off so the other can turn on. If both are on at the same time kaboom. A well designed power supply also reads the mosfets temps and if they get too hot the power supply shuts down anyway regardless the OPP. Close to 200ºC is too high
Seems interns have been put in charge of their factories.
@@damionb7946 smells like you don't know what you are talking about
there's many things that could kill mosfets and one of them is cross conduction from having not enough dead time as you said. if the problem was dead time then paralleling mosfets won't help.
@@punktkomma9489 How do you conclude that? It absolutely is possible to run mosfets in parallel. If you want them to run absolutely perfectly in parallel, you'd need to miller plateau match them all. Most applications can handle a few microseconds switch on time difference though.
