notice: this does NOT affect GP-APGM/Aorus PGM units. This is the same OEM, but different components and main design has been used here.
GP-PGM
GP-APGM
Summary
Gigabyte's recently announced unit has an issue, where the OPP is set too high, causing the main FETs to explode because of it being unable to handle the load. There is no public statement from Gigabyte and I didn't reach out to them about this, but have reached out to Aristeidis Mpitziopoulos, better known as Aris about what exactly happened. All info provided is from his video and review below.

My thoughts
I think Gigabyte's response to this is unacceptable and very worrying. They've been offered the sample back, they've had a request to send a second unit to let the reviewer test it out and declined both of these. This is a serious issue where there isn't even a statement given. All that's been done is a couple unit put into testing by R&D where they didn't find anything. I honestly want Gigabyte to call back all the units, change the FETs to a higher quality level and supply the new designs to the affected consumers. This is a serious issue that has very likely been caused by cheaping out on main components, as GP-APGM didn't show this.
Further information
The OCP is set at around 130%
The main fets are 2x Jilin Sino-Microelectronics JCS18N50FH (500 V, 11 A @ 100 °C, Rds (on): 0.27 ohm)
The failure happened after the unit succesfully shut down on OPP/OCP, where it was turned on again after 5 minutes.
The issue is likely caused by cheap main FETs, a too high set OPP/OCP, a design error or a combination of these.
It does not affect the similarly named GP-APGM or any other Gigabyte units from what is currently known
