A user on LinusTechTips told me to avoid the G3 due to protection issues, so I went to read some reviews and indeed there are issues.
The EVGA G3 suffers from protection issues, specifically its OTP and OPP.
Quote from Aris:
The PSU shuts down with 77.82A on its +12V rail. We suspect that this is not because of over-current protection on this rail, but due to under-voltage protection. In our opinion, this PSU's over-power protection is set too high; it should kick in at around 120-125% of the maximum-rated capacity to keep the +12V rail within spec. Over-temperature protection has a pretty high triggering point, too. This is something we've encountered in plenty of semi-passive PSUs.
OTP is set very high in our opinion, since we had to apply a huge thermal load on the secondary side to trigger it. The bulk cap's external casing nearly melted during our OTP evaluation.
We didn't get any OCP results because our unit died during the OPP test, meaning either that this particular sample had a problem or OPP is set very high. Note that we conduct these tests at normal ambient temperatures, below 30°C.
OTP is set very high, as we also noted in our 850 G3 review. This is a 50°C-rated PSU, so it is normal to have a high OTP triggering point, but we'd be more comfortable if it was closer to 130°C.
This is from three different retail units. This doesn’t look good for the G3. It may be time to start recommending against this unit.
