Gigabyte releases a statement on failing (and exploding) power supply models

A hot potato: After reports from customers and hardware reviewers that two models of Gigabyte's desktop PC power supplies were failing, damaging other PC components, and even exploding, Gigabyte is making some adjustments however those may only fix one of the PSUs' reported issues. Gigabyte is also offering a return and exchange program.

If you have a GP-P850GM or GP-P750GM PSU, according to the appendix at the bottom of Gigabyte's statement, they're allowing returns and exchanges for serial numbers SN20343G031011 to SN20513G022635 for the P850GM, and serial numbers SN20243G001301 to SN20453G025430 for the P750GM.

Hardware reviewer Gamers Nexus tested several of these PSUs and 50 percent of the P850GMs and P750GMs failed in an "explosive capacity." One of them suffered a "catastrophic" failure, while under 60 percent load. They blew three load-testing fuses, and fried an RTX 3080.

YouTube channel Hardware Busters also reported an exploding P750GM. Similar reports have come from customers leaving reviews on stores like Newegg. The P850GM and P750GM have 39 percent and 53 percent one-egg reviews on Newegg respectively, with reviewers indicating problems including PSU failure and damage to other parts.

Gigabyte's statement released last week acknowledged these issues, primarily the failure of the Over Power Protection (OPP) system which is meant to shut down the PSU if the wattage exceeds the limit it was designed for. Gigabyte set that limit at 120 percent to 150 percent of the advertised wattage -- 1020W to 1300W for P850GM, and 900W to 1125W for the P750GM.

"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," the statement reads. "This level of extended testing could severely reduce the lifespan of the product and components."

Gigabyte has now set a new limit of 110 percent to 120 percent of the advertised wattage. That's 950W to 1050W for the P850GM, and 825W to 925W for the P750GM.

This alone however doesn't address all the issues reviewers and customers pointed out. Many Newegg customers have reported their PSUs dead on arrival. A lot of them didn't even buy the PSUs independently, but ended up with them because Newegg bundled them with Nvidia's new RTX 3000 series graphics cards, which have been plagued by supply shortages since they came out late last year. Some customers could only get their hands on an RTX 3000 by buying it with one of these PSUs as part of a bundle.

While Gigabyte is scum and I would never buy their products again if I can help it, I think retailers like Newegg should also share part of the responsibility here because for whatever reason or pressured, they willingly sent defective products and ones that are potentially dangerous and would make them liable since for a consumer Newegg is the one that basically gave em away with the bundle.

Oh and yes this peak, empty, corporate non-apology that basically reads "We're sorry we got caught and Tech Jesus confirmed it publicly" because that's the only thing they regret.

Ι have owned 3 faulty Gigabyte GPUs a 8800 GTX, a GTX 580 SOC, and (finally) a GTX 780 TI GHz Ed.

All high-end models, top of the line.

I never bought a Gigabyte product since the 780TI and will never do so again.

Will note reasons GIGABYTE cited to refuse RMA:

1st card artifacted 2 months out of warranty so no RMA, 2nd card had defective fans & Gigabyte said they don't manufacture the fans so they have no responsibility arising thereof, 3rd card was all over the internet b/c wasn't stable at advertised clocks on box and website, Gigabyte said no RMA b/c the card works fine with an underclock.

Gigabyte, you never win with Gigabyte if you are a customer.

Right back at ya, Gigabyte.

The only conclusion I'm able to draw here is, Gigabyte should stick to what they do best, and that's motherboards. and leave PSUs to those who do them best. Which includes, (IMO) Antec, Delta, and Seasonic.

I've never had a bit of trouble with Antec's "Earthwatts" series, which includes the "D" suffix models, built by Delta.

FWIW though, I've never seen any maker's supplies get a 5 star rating at Newegg. It's often said,"A**holes and opinions, everybody has one of each", and it would seem that manifests itself rather abundantly in PSU reviews..

It's bad enough that Newegg dumps extra product on GPU buyers, but to do it with defective parts is reprehensible.

Retailers have sunk to new lows with the current crop of graphics cards.

Use small claims/credit card company to sort that out.

Thing is, there is a story like yours for every manufacturer of PC components. They can all be as bad as each other.

I'm just confused how you went back a second and then a third time with soooo many options available.

Glad to hear you say that about the mobos because I just bought an Aorus X570 Ultra about a month ago. Seems to be ok. the audio seems to have some glitches though.

They don't manufacture the fans??? The don't manufacture the chips on the card either but they should honor the warranty if the card fails. That doesn't sound right.

Wow, they shafted you on the fans because they don't manufacture them, that's a new low...

Not when the junky extra PSU can net them a further GPU sale , as the older one is brought down by a thing called Gigabyte (OPP). These PSU's are probably not even made by GB but subcontracted out, probably to a cheap tired Chinese Supplier
