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

Its just amazing how Gigabyte have carved a big space in the PSU market only to have all that go away due to cheaply built PSU from a questionable OEM, they should have just rebranded a Seasonic or a CWT platform like most do, its safe and a company like Gigabyte can afford that ten time over

Wow.. their comment on how the testing doesn't reflect real world usage pretty much guaranteed I will never own another Gigabyte product. I was just looking at one of their boards.. it is now out of my cart.

The only course of action here really would've been a full unequivocal product recall.

They had reputable boards during AM3+ but after that I dont trust them.

Not to mention look at all the revisions their boards go through

Every company thinks they can compete in the PS market until they try and fail.

It takes a special one to release a statement like this though.

I have an eligible GP-P850GM still in shrink ramp from when I got it with a newegg combo in 2020. I guess i'll do the replacement, I didn't want to use it for anything because the reviews on these units was so bad, I guess the replacement should be better?

I love it how they stress this part first:
for extended lengths of time repeatedly close to the 120% to 150% OPP trigger point

So it makes it seem like it's user/reviewer's fault that they went kaboom after surviving the OPP test and then they decide to lower OPP to 110-120%.

It's the same psu with essentially a microcode replacement. They aren't actually changing any hardware, just how early it triggers the protection.

I'd still not trust it personally until there was a hardware fix.

This is called damage control.
Too bad for them it's too late.

Gotta love that corporate damage control gibberish. They made a poor quality product and now try to shift the blame on reviewers and users. The whole point of the protections is for the product to never exceed safe limits, not to "maybe not to exceed them by too much sometimes, kind of...".

It is sad to see this kind of response from them. Time to avoid gigabyte products for long period. If mobo and gpu will be below 30% then I'll rethink. PSU should be avoided for next 5 years.

I wouldn't think they are any better they just adjusted the shut off range so they are still garbage as they were exploding within their rated range.

The main problem is all these garbage supply units flood the market and great companies like PC Power and Cooling go out of business trying to provide a quality product.

There needs to be a forced recall.

Oh... That's very interesting non-apology.
Especially the "casting doubt over the quality of our products" part... which kinda suggests that their stance is still the same - not a quality issue but a perception issue :banghead:

I think that Intel, AMD and Nvidia also guilty. Because make design of products with much more power consumption and bad very big peaks and PSUs with little older design which is enough for older PC hardware is not enough for requirements of new models of PC hardware. I don't wish to think how older model PSUs will work with Intel Alder Lake or with AMD CPUs with ZEN4 architecture if rumors of how be it's consumption is true. There is problem with consumption of modern parts when overclock...Has big difference between consumption of OC of parts to 2014 when has gap to "play" OC without too big problems and parts after 2014 which when load is big work very close to limit. After this limit when OC consumption growing exponentially.
