A pair of Gigabyte PSUs appear prone to harmful failure
Multiple reports suggest Gigabyte's GP-P750GM and GP-P850GM power supplies could be at high risk of serious misfunction or nonstarter. In some cases, these PSUs have even been going away verboten with a actual bang.
The event was firstborn noted past well-known PSU commentator Aristeidis Bitziopoulos in his survey for TechPowerUp in late 2020. In this review, he concludes that "Contrary to the Aorus PSU blood line, which was amazingly good, this combined is a disappointment…. For starters, my sample died during the over force evaluation, which is a great shame. The primary switching FETs blew risen with a pi of a bang."
He also explains the government issue further in this Computer hardware Busters video.
An exploding PSU is about as bad as it gets. However, the sample size is besides as small American Samoa it could possibly be here, so further testing is required to trace anything more or less a firm conclusion.
With that in mind, Bitzopoulos well-tried two farther 850W samples. Some of which acted as they should without computer error. He also tells me he asked around at distributors and constitute that, at least in Europe, these models don't have unusually high RMA rates.
From this, it would be easy to sham the 850W model is a bit less prone to surrender the ghost (which May be geographic) and that perhaps the 750W simulate was a poor sample. However, that's far from the end of this story.
For one, there are other oddities or points of concern with the Gigabyte General practitioner-P750-GM that Bitzopoulos outlines in his review. These include a high OPP protection threshold, poor timbre FETs, unknown caps, a squabby EPS cable, and an falsely advertised lover.
But that's still a far cry from exploding. It's instead further probe from another source which appears Sir Thomas More troubling.
Following further reports from viewers regarding failure rates of Gigabyte GP-P750GM and GP-P850GM power supplies, Gamers Nexus also investigated the issue. It reports that 5 of the 10 units it tested failed "in an explosive electrical capacity," which you butt clearly catch an exercise of in its video. The surviving PSUs passed testing without issue, which also includes one power add in an endurance test for an entire month.
Clear not every GP-P750GM and GP-P850GM unit of measurement is immediately imperfect, just those that are could have disastrous consequences.
Gamers Nexus says the PSU issue IT's experienced could stem from an issue with either OCP, OTP, Beaver State OPP. These are circuits responsible for the shutdown of the PSU when certain values are greater than the PSU is reinforced to handle, such as high underway or temperature. From its testing, these PSUs are able to run at a high treasure before shutting dispirited this agency, and in close to cases exceed these limits ahead turn soured.
Bitzopoulos tells me he believes that the return at last comes down to invalid project.
"I strongly think that this is just a bad designing, the FETs are non driven correctly and although in quick pre-checks and normal conditions the PSU can be ok, there are cases (non merely under stress) where they betray. The timing of the FETs is non decline and this is due to a bad logic gate driver or a bad implementation."
He too say it's plausibly an easy-enough fix once identified, and expects the OEM producing this PSU for Gigabyte, MEIC, to execute a mute muddle to address the cut, if it hasn't through with so already.
That still leaves existing General practitioner-P750GM and GP-P850GM power supplies, which appear prone to higher failure rates than is the norm, at outsize. These PSUs feature been shipped aboard graphics cards As a part of Newegg Shuffle bundles, likewise, and that could make for quite a few currently in use up aboard the latest GPU silicon.
Gigabyte is at the least aware of the issue, though we've not detected of any further investigation along its part just yet. Bitzopoulos informed an R&ere;D supervisor after testing, who told him that of the five samples Gigabyte tested, all five passed OPP tests. And that appears to have been the end of that.
We'll deman ratification from G to be surely of the full extent of this issue, so I've reached out for an official answer and bequeath update this clause if I hear anything back.
For now, my advice to those with this PSU installed would be to switch over information technology out for another. It's not an ideal solution but information technology's simply non worth losing your graphics batting order or opposite components to a faulty PSU, especially while kit is so precious and prices soh high.
