Gigabyte Responds to Exploding PSU Allegations!

Over the last couple of weeks, there have been a number of accusations from various media outlets that the Gigabyte GP-P850GM & GP-P750GM power supplies have something of a bit of a design flaw, namely, that they’d basically been blowing up while under load! However, it was somewhat unclear whether this was a relatively isolated incident or a legitimate failure in the product. Following a report via Videocardz, Gigabyte has officially responded to the news, and, by and large, they’ve confirmed it to be (probably) entirely true!

Gigabyte (Basically) Confirms Faulty Power Supplies

The short version is that while Gigabyte hasn’t acknowledged any particular fault per se with their GP-P850GM & GP-P750GM PSUs, they have acknowledged that the built-in limits on the overpower protection (OPP) are likely a bit too high. For those of you unaware, OPP is (in its simplest terms) protection built into pretty much all modern power supplies that should, at least in theory, shut them down if the PSU is being asked to draw too many watts and/or is running excessively hot.

In response to this, Gigabyte has confirmed that the power supplies have now been revised to the following specifications:

“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

Voluntary Recall!

If you have recently purchased a GP-P850GM & GP-P750GM, while in theory, it should run perfectly fine as long as you’ve got your maths correct in terms of how much power your components draw, Gigabyte is still offering consumers the option to have their model replaced. This applies specifically to those under the following serial numbers:

  • Model name:GP-P850GM – S/N From SN20343G031011 to SN20513G022635
  • Model name:GP-P750GM – S/N From SN20243G001301 to SN20453G025430

For more information, presuming you have a GP-P850GM/GP-P750GM PSU under the above serial numbers and wish to have it replaced with the revised design, you should contact Gigabyte technical support, which you can check out via the link here!
