Those are all models of different ages. The G5 came out in 2019, G6 in 2021, and GT in 2022. EVGA also doesn't make their own PSUs so each model has a different OEM. G5 OEM is FSB, G6 is SeaSonic, and GT is HEC. Of those the G6 and GT are the overall best, however, in 2025 it doesn't make sense to get ATX 2.5 PSUs instead of an ATX 3/3.1 PSU.

r/EVGA on Reddit: Do not buy the EVGA 1000-G6 Supernova Power Supply
January 26, 2022 -

This "Compact" power supply paired with a 12700k and 3080 graphics card gets extremely hot and has a ridiculous 0-100 fluctuating fan curve making it unbearably annoying to hear while playing any game or doing intensive GPU tasks.

At first I thought the product I received was defective so I sent it to EVGA for RMA (20$ shipping) after which they sent a different one right back but said the original "passed testing". So I try the new one in my build and have the same exact issue. I send them videos of the fan revving up and out down as well.

At this point I had also ordered an EVGA 1000-P3 which is not "compact" but uses the same modular cables to test in my build. It has absolute no heat or noise issues and performs completely fine, ruling out my case, airflow, or anything in my build being an issue.

EVGA offered me another RMA but I'm guessing that would just be a waste of 20$ to ship. I submitted more feedback on my product performance comparison above and received the following reply - https://imgur.com/VF2wtWX

I'm essentially posting here as a warning to anyone buying this power supply. I would absolutely not recommend it to anyone looking for 1000w capability, it is a defective product and unless you enjoy extreme heat and noise please do not purchase it if you have a high end CPU and graphics card. I'll be keeping the 1000-G6 as a backup/spare as it is completely not usable from my point of view unless I wear noise cancelling headphones. It's a little hard to capture but here's a video of the issue - https://www.dropbox.com/s/sqj5lhklkx7cs7v/20211226_220617.mp4?dl=0

Difference 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 More on forums.tomshardware.com

EVGA Power Supply GQ vs G6, what's the difference?
just on surface its only difference you can see in modular cables. but deep dive it will show you that its completly different unit. EVGA g6 is bassically seasonic focus GX upgraded platform with better parts made by seasonic while GQ is by FSP company on some not that well known platform. EVGA g6 is desinged with LCC while GQ is ARCF. not going into too much details here, LCC desing is better one evga g6 offers 10 year warranty, EVGA GQ offers 5 year warranty evga g6 is A tier unit, considered as one of the best on market while EVGA GQ is B tier unit and some other details which i dont believe will be relavant here. you bassically ordered mercedes alongside psu units, but ended up getting KIA or similar brand car. its not necceseary bad but u wanted mercedes, end of story. now can that cause problems? i cant say for sure but if i were you i would definently send it back and get as you requested for!

EVGA Supernova 650W G6 or G7

I went with a 1000w G6 earlier this month to go with my 3080ti, no complaints so far. With the way GPUs and cpus are heading, 1000w isn't a bad idea to have some future headroom.
