Gigabyte amends its "explosive" PSUs, puts out official statement

Gigabyte earlier today released an official statement regarding its GP-P850GM and GP-P750GM power supply unit (PSU) models that have been in the news. These PSUs have been found by reviewers like TechPowerUp and Gamers Nexus (GN) to be "explosive" during heavy load stress testing. It was also reported that the P850M and P750M would often be bundled with high-end graphics cards, which are generally quite power-hungry, during the Newegg Shuffle drawing system.

In its statement, Gigabyte has said that it is "aware of certain media outfits casting doubt over the quality of Power Supply models GP-P850GM and GP-P750GM" but has also remarked that it "appreciates and takes into consideration any feedback and suggestions" from such sources.

In response to the heavy load testing that PSUs have to endure during third-party reviews, the company has stated that such "level of extended testing could severely reduce the lifespan of the product and components of the GP-P850GM and GP-P750GM". As such, Gigabyte has now lowered the Over Power Protection (OPP) trigger values in these two PSU variants to 110% ~ 120%, whereas previously they had been set to 120% ~ 150%.

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: 1020W ~ 1300W

    After: 950W ~ 1050W

  • GP-P750GM- Adjusted OPP trigger point range from 120% ~ 150% to 110% ~ 120%
    Before: 900W ~ 1125W

    After: 825W ~ 925W

Gigabyte has also provided a range of serial numbers (S/N) for the two PSU models which are eligible for its Return and Exchange service. Units outside of these S/N have the new OPP setting in place.
