‘Exploding’ PC Power Supplies Are ‘Unsellable’

‘Exploding’ PC Power Supplies Are ‘Unsellable’

Following a ton of complaints from disgruntled buyers, Steve Burke and Gamers Nexus have spent the past few months purchasing and testing a couple of models of Gigabyte power supply units, to find out why so many of them are “exploding”.

The two PSUs in question — the GP-P750GM & GP-P850GM — were earlier this year sold by Newegg as part of a forced bundle, where anyone buying select RTX series GPUs had to buy the power supply along with it. A shitty move regardless of what happened next, but what happened next was that people started installing these PSUs and finding that they failed. A lot.

And not just fail, but sometimes fail spectacularly, with reports that a percentage of them were potentially “explosive”, in that they could catastrophically fail at a moment’s notice, producing sparks and sometimes frying any connected hardware along with it.

In an effort to wrangle all those anecdotes into something more scientific, Gamers Nexus have since February been buying up a ton of these units in bulk and testing them out, finding that while the P850 is bad, the P750 is criminally poor, with astronomical failure rates — 50% of those they’d bought! — that ranged from simply arriving dead in the box to blowing up while testing and taking GTX cards with them.

After taking a close look at the PSUs they found that they were questionable in terms of both design and the components used, and that “Gigabyte and Newegg are ultimately dumping an unsellable product on desperate buyers”.

The full video, which shows all the testing done on the units, the findings from said testing and the conclusions as to why these power supplies failed so catastrophically, is below (though note that it runs for around 30 minutes, so clear some time from your schedule before settling in).

  • I bought this for the computer i was building for my mother….errr…..i think im gonna get a new and different PSU.

    • I’ve had legendarily bad experiences with Gigabyte from motherboards spontaneously cooking themselves to fan failures on their GPUs and their refusal or honour their warranty repairs after said problems happened. People should buy from literally anyone else.

      • Ive been pretty lucky with a lot of parts, ive only had one video card death, and one motherboard death in 25+ years, all of which were after many many years of use, so i dont have any brand horror stories beyond maybe the refusal to by intel parts cause ive always hated their stock CPU heatsinks, it helps that i do a fair chunk of research before buying each new setup, except for the most recent one, which has already provided a whoopsie in this article.
        Hard drives however. Ive had more hard drive failures than i could possibly ever count.

  • Gigabyte must have known these PSU’s were dodgy, as such they should be punished for intentionally releasing such products. If Newegg knowingly pushed these dodgy PSU’s on customers wanting a GPU they are just as culpable.
