just saw the deal on the corsair psu: https://www.ozbargain.com.au/node/594979
I found out no one posted this one yet, this is EVGA GA 750W Gold rated full modular PSU. 149 only, usually 180 - 199.
I have been using both brands for many years, usually I would go for Corsair because they are cheaper. (not anymore)
back in 2015-18 a SuperNova G3 is usually 10-30 bucks dearer than the Corsair equivillent.
but in the past year or so EVGA have lowered price on the PSUs, my latest build, after doing few research, I went for EVGA G5 1000W + RTX3090
(still only 17 - 19 FPS go absoultely max setting @4k with cyberpunk 2077)
I was going for RTX3080 + 750W GA PSU from EVGA, and during my price ressearch I found this deal, they are not on staticice yet.
so if you looking at a 750w psu, this could be a good choice.
