Earth, for now
Just watching a video now about this PSU and I have seen it on sale at a UK competitor and thought that it is best to link it here....


the high failure rate is concerning, GN bought ten of them and 50% failed catastrophically, one possibly causing a GPU to also be damaged.

"Gigabyte's GP-P750GM & GP-P850GM" both of these units are noted to be problematic.

Avoid this unit.

Techpowerup pretty much slated it in their review as their test unit blew up when checking the over current protection. Gigabyte didn't even ask them to return their unit so they could examine it to see what went wrong. These should be recalled and redesigned using quality components instead of cheaping out on important components. Ditching MEIC as a OEM would be a good move too.
 
I saw this and wondered what the reply going forward might be from Gigabyte. You can buy them still in the UK. But just under £100 I think I'll pass....
 
They are listed, the 750w one, at £59.99. Still whatever the price they are best avoided. Not everyone will be aware of the potential problem tho.

They were listed on the hot uk deal site today but the thread seems to have gotten locked after people pointed out they weren't even just slightly bad, but fireworks bad.

Modern times: TPU write proper review with actual written text back in December. It gets little attention. Some loud youtuber makes a video and it is all over the place. Okay so they did actually go out and buy a bunch to see how bad they were but still.

Old-fashioned me.
 
Sadly I have the 850watt version of this in my PC.

Can anyone recommend a replacement.

I'm looking at the 2020 (possibly 2019) version of the Corsair RM850.

My system specs -

Ryzen 5900x
RGB 32GB
RTX 3070
4 Old Fashioned Spinners
2 Sata SSD's
2 NVMEs
Soundblaster AE5
Elgato Stream PCIE

5 case fans (inc AIO)

I built this PC almost a year ago and have upgraded the CPU/GPU after getting lucky a couple of times. My original 750 watt which was about 5 years old was replaced with the P850GM just before Xmas, it couldn't handle the 3070 & 5900x at full chat when playing Anno 1800 and would soft reset the machine when assets loaded in.


Many Thanks

Perhaps this could be a consideration, with ten years warranty....

My basket at Overclockers UK:
Total: £144.49 (includes shipping: £10.50)​
​

seems reasonable and rated as a Tier A PSU.
 
Forcing psu + gpu bundles and insisting on entire psu + gpu bundle returns if any problems sounded like some sketchy anti-consumer BS to shift this garbage.

Frustratingly I can't remember who made the original design but it looks very similar to the design Superflower (not their original work) used to make their original basic consumer PSUs but with [even] cheaper components.

EDIT: I might even be getting mixed up with who it was using that design - it has been quite a long time.

The GP-P850GM says it uses Japanese caps on the box. I'm not sure whether to keep it for a lower spec machine or to throw it in the E-waste at work.

Only as bulk/primary cap which is one of the less critical parts.
Rest are from Chinese garbage bag.
Along with most of power semiconductors.
 
Gigabyte has replied https://www.gigabyte.com/us/Press/News/1930


They are saying they have adjusted some of the protection settings and are offering a replacement service so you can send your old one back for a replacement (assuming you still want this junk in your pc)


Unfortunately, they won't back down on the failure rate, saying that gamers nexus only exploded the psu's because they used load equipment... right that's why high quality psu have no issue in reviews and then they stated the psu's have always been good for normal usage... right that's why user reviews on new egg are horrendous
