GIGABYTE is aware of certain media outfits casting doubt over the quality of Power Supply models GP-P850GM and GP-P750GM. GIGABYTE takes pride in the design and quality of our products and as such, takes reports of this manner extremely seriously and therefore would like to address the reported potential issues as follows:

For desktop PC systems, there can occasionally be instances where the peak wattage can exceed the intended usage range. During such instances, the GIGABYTE GP-P850GM / GP-P750GM model power supplies include the industry standard built-in safety feature "Over Power Protection" (OPP). The OPP safety feature is designed to shut down the unit when the power load exceeds the wattage the unit was designed to operate within. The OPP was set to 120% to 150%, 1020 W~1300 W for GP-P850GM, and 900 W~1125 W for the GP-P750GM.
GIGABYTE, appreciates and takes into consideration any feedback and suggestions from our media partners and PC hardware professionals. We were made aware by third parties of concerns regarding potential issues of the GP-P850GM and GP-P750GM tripping at high wattages when tested via DC Electronic Load equipment for extended lengths of time repeatedly close to the 120% to 150% OPP trigger point. This level of extended testing could severely reduce the lifespan of the product and components of the GP-P850GM and GP-P750GM.

To address these potential issues raised by third parties, specifically, those discovered during their testing via DC Electronic Load equipment for extended lengths of time repeatedly close to the 120% to 150% OPP trigger point. GIGABYTE has made adjustments and lowered the OPP on GP-P850GM and GP-P750GM to the below values.
  • GP-P850GM- Adjusted OPP trigger point range from 120% ~ 150% to 110% ~ 120%
    • Before: 1020 W ~ 1300 W
    • After: 950 W ~ 1050 W
  • GP-P750GM- Adjusted OPP trigger point range from 120% ~ 150% to 110% ~ 120%
    • Before: 900 W ~ 1125 W
    • After: 825 W ~ 925 W
GIGABYTE highly values the confidence and trust all our customers have in our product quality and after sale services. GIGABYTE would like to stress the potential issues that were reported, only seemed to occur after very long time periods of extreme load testing via DC Electronic load equipment and would not be typical of any real world usage.

GIGABYTE GP-P850GM and GP-P750GM PSU's included industry standard power protection designs OCP, OTP, OVP, OPP, UVP, and SCP.

Safety certification from various countries to ensure safe and stable operation of your system.

To offer customers complete peace of mind, any serial number not listed in Appendix 1 are the amended OPP settings as listed in point 3.
Despite the fact that both before & after OPP adjustment versions are reliable for real world usage, we still offer owners of the GP-P850GM or GP-P750GM products included in the serial number range listed in Appendix 1 can apply for the GP-P850GM and GP-P750GM return and exchange service.
  • Model name:GP-P850GM: S/N From SN20343G031011 to SN20513G022635
  • Model name:GP-P750GM; S/N From SN20243G001301 to SN20453G025430

Bork BorkYou only buy Seasonic or Corsair PSUs. Nothing more nothing less.

If you somehow want a faulty product then always go with EVGA.
The system I have being built will have this EVGA PSU:
EVGA SuperNOVA 1600 T2, 80+ TITANIUM 1600W, Fully Modular, 10 Year Warranty

It was also reviewed here on TPU:
EVGA SuperNOVA 1600 T2 Review
It can't be worse than any of the other PSUs out there, and based on its specs, I would rather this one than Corsair's.

I have always found Gigabyte PSU's unreliable. This just confirms it even further.

I'd enjoy this comment if my psu and vid card weren't made by evga

Companies are allowed to respond however they like so I’ll grant them that respect but as consumers ALL OF US need to remember this when Gigabyte releases another PSU lineup next year by not buying their unacceptable quality product

MarsM4NActually it's pretty wise to choose a "overprovisioned" PSU with around 1/3 more watts that you actually need.
Most top tier PSU’s already do this. I have pulled 965w from an old TX-850 fairly routinely.. probably why it doesn’t work very well anymore :D

mamaSort of is... new boards have new power stages and components.
Sure, but that's simply board redesign/optimizations that were released with these (for example the MSI Tomahawk X570 vs X570S). The chipset itself remains a X570, nothing changed there.

Just buy a PSU only if you can find a detailed review about it, that's all that matters. All of these companies have made it sure that it is impossible to tell whether or not something is of good quality or if you are overpaying for a brand name.

Corsair has also crappy units which are sold purely with its known brand. Seasonic is a known high quality OEM though and I agree with that as I also have a Seasonic unit.

Personally I'd never buy a PSU just because of the brand/manufacturer. Corsair doesn't manufacture their PSUs themselves.

So does Seasonic.
Bork BorkIf you somehow want a faulty product then always go with EVGA.
EVGA does have some good PSUs, they just don't care about sending review samples much. As we shouldn't care about buying their PSUs that there are no reviews on (which is like 80% of their current lineup).
Corsair doesn't manufacture their PSUs themselves.
Doesn't matter in the slightest. Corsair for one cares about the quality of PSUs they sell and they actually have a team of competent engineers to evaluate their products before letting it in the market (in contrast with say, Gigabyte as proven by all this shitstorm). They also send out review samples for all their new lineups, including budget, in contrast with Seasonic. Go try to find some reviews on Seasonic S12III, Core GC\GM\GX, and B12 BC \ G12 GC. So if anything, it's Seasonic who's guilty of trying to sell their products solely based on the brand recognition and marketing.
And no, i'm not a Corsair shill, i'm just saying that brand doesn't matter as long as the product is good, which you should determine based on reviews, not the brand.

Buying crappy PSUs is not the same thing as buying PSUs from a crappy brand. I stand corrected.

Lots of expensive PSUs (even Platinum/Titanium rated ones) suffer from coilwhine and the first one that comes to mind is shut up!, Dark Pro series was it?

Afaik corsair made their name in the psu business rebadging Seasonic psu. Currently I think they handle the design in house and send it to a generic manufacturer, but haven't read anything too bad and my rm750 is performing well and has 10years warranty so i'm not worried.

As allways, any manufacturer can do shitty products, even seasonic (the recent hi power sfx they did, it was like 1000w or something, and it sucked)

EVGA have more or less about a hundred PSU models, built by many OEMs, the primary series Supernova G2,3, P2, T2 are great quality built by Superflower, the rest have inconsistent quality from each, not bad or anything, just average

Seasonic doesn't have SFX(-L) units more powerful than 650W, and what they do have is actually pretty decent, SFF units aren't exactly their Achilles heel. It's more about their more known units, i.e Focus and Prime, both of which had or have problems with transient-heavy GPUs, sounds like some inherent design flaw in the protection circuit. Hopefully, a new platform would solve that (they seem to be kinda beta-testing it on EVGA for now). But they also have S12III with no OCP at all, and units with almost zero review coverage - Core and B12/G12 series. Brand loyalty is never a good thing but at this point you would have better chances of getting a definitely good PSU if you go for Corsair than Seasonic, for better or for worse. And Corsair PSUs are mostly made by CWT today, which are making PSUs for a variety of other brands, often very good units too. But the key to a good PSU is not only a good OEM, but also a company which cares about their products, whether they make them themselves or outsource.

Well you certainly sounded like one here. ( see bolded and italicized part) But you are right about the rest. Every brand has had their share of crap products, and their share of really good ones, that still doesnt mean one brand is better than another, most everyones opinion is based on their own experiences with a unit. Those that still work on the "geek squad", see failure rates more often. All reviews have some fault or other, and someone will always voice their disagreement.

Bork BorkI'm sorry for your loss.
As Hand Banana would quip, "You think you could back that up?" If not, I don't think I have much to worry about with the particular model I went with. It was hard to get that PSU because a lot of cryptocurrency miners were buying them up & actually preferred them over the Corsair 1600-watt equivalent ones(wasn't a quality issue, but something with the connection options if running multiple graphics cards. I recall reading something about this in the reviews at pcpartpicker.com).
I haven't spent too much time researching power supplies, but I do know that if there were quality/reliability problems with the EVGA model I picked, my builder would've discussed it with me and given me better options. Some EVGA PSUs are cheap & have questionable reliability, just as any other brand, but this is not true when it comes to "all" EVGA PSUs.

The G2/P2/T2 series use a modified Super Flower Leadex (1st generation) platform. I use a 1300 G2 on my system, it was reviewed by Aris here on TPU in 2013, and has always been a solid power supply. Quoting him, "you could probably start a truck with this unit", and he'd be right. There's no reason to worry, the 1600 T2 is one of the most powerful and reliable power supplies on the market, and I imagine that it would have costed you a small fortune in the mining age. The only "issue" with it is the extremely high inrush current, something that my unit also suffers from. But that's ultra high capacity analog power supplies for you :D

As long as it doesn't explode, burn the house down, fry any of my components, and is reliable, I'm happy with it. Both the Corsair AX1600i & EVGA SuperNOVA 1600 T2 seem to be on par with each other. They both have their pluses and minuses. The one thing that I don't like about the Corsair is the need to install additional software(i.e. Corsair Link), but I guess its necessary for those needing the extra control/tweaking.

Installing Link/iCUE isn't necessary, though I don't see why you wouldn't, one of the strengths of the AXi series is that they have real-time consumption and efficiency monitoring, per cable/connector (HXi has only overall statistics as it's an analog design), and the 1600 T2 is in practice a bit less efficient than the 1500i (again, inefficiencies of a traditional analog design), the 1600i is better than both (state of the art digital design using GaN FETs, it's unique and has the highest efficiency out of every single power supply out there at the moment), but i'd probably be lying if I told you that you would notice in every day use. The 1600 T2 is solid, congrats for even being able to obtain one nowadays.

Though, we've gone OT here at this point. :toast:
