Information about the distinctions between G5, G6, and GR EVGA power supplies.
Hi I was planning on getting an EVGA 750 or 650 power supply, but on amazon I see that there’s 3 options: G5, G6, and GT. I notice the GT is cheaper but is there a big difference between the three? Also which one is the best of the three
These models represent a range of ages. The G5 was released in 2019, G6 in 2021, and GT in 2022. EVGA does not manufacture its own PSUs, so each model uses a different OEM. The G5 uses FSB as its OEM, G6 uses SeaSonic, and GT uses HEC. Among these, the G6 and GT are considered the top choices, though in 2025 it might not be practical to opt for ATX 2.5 PSUs instead of an ATX 3/3.1 PSU.
For a 650 or 750 wattage, you should consider a PSU that matches your power needs and efficiency requirements.
You might also purchase the suitable adapter cable. As long as the PSU can manage transients, everything is fine.
The main reason to steer clear of EVGA at the moment could be the absence of warranty assistance. They haven't fully stopped working yet. However, eventually they won't be able to help you with replacements.
Well, yes, having six wires work together to handle 675W indicates they need to be larger. (9 amps per wire). Triple 8-pin configurations used nine wires for the same task. Many premium PSUs also employed 16-gauge wiring, which could reach up to 972W at maximum, or about 780W with an 80% safety margin. Even a more modest 60W (5A) per wire would provide around 540W. This aligns more closely with the design goals of the 6-pin and 8-pin 18-gauge models. That's why reviewing PSU specifications matters—don't rely solely on them.
