is EVGA's 650W Gq good enough for a ryzen 2600x and an rtx 2080 build ?
and is a 750w an overkill ?

650w is good. 750w is good, depending on sales either can be cheaper. As in cost, not quality. The $30 worth of insurance difference between a $80 good psu and a $50 POS is small pittance vrs the $1000+ you are about to drop on a nice pc.

NO, I wouldn't use that PSU with a high end GPU.

Better to get a higher tiered unit like:

Seasonic Focus Plus
EVGA G2
Corsair RMX

650W is fine, 750W is also fine.
I second this post. I will also add this: go for a 750 watt PSU or higher, even though 650 watts is enough.

Minimum proscribed recommended size for a 2080 is 550w.

A 2080 will pull 250-260w.
The 2600x will pull 100w
The rest of the pc will be lucky to pull 100w.
And that's maxed out, everything running at peak, 450w. Even with a massive OC (not really feasible on the 2600x, it's already cranked) of 100 extra watts is only enough to max out a 550w psu. And gaming loads on a psu end up @ 60-70% draw. Mostly you'll be in the 350w-375w range.

A good 550w is plenty, if a little tight, a good 650w is good, if a little much, 750w is over the top and higher than that is totally unnecessary.

Hey there… What would you consider the major differences between the Evga G3 You suggested, and the GQ the OP was considering?

I am shopping PSUs, as well, but I don’t think my usage will be nearly as high as the OP ‘s.

I think for the GQ series, EVGA teamed up with FSP to produce these units, which are slightly one step below the G2 series. So, I assume the G3 might also be better than the GQ model. I think there are four GQ PSUs, and all are 80 Plus Gold certified, and use only Japanese capacitors.

Apart from that, there isn't too much of a difference between make and build quality of the G2/3 and GQ units, IMO.
