Evga Supernova 650 Gm, 80 Plus Gold 650W and 3090

[The_One]

Just putting my watercooled lian li 011 dynamic mini build together and just realised the mini only accepts small form factor psus meaning my 750 wont fit

i need to stick with evga so my cablemods cables fit

will this 650w psu handle my palit watercooled 3090 and a 5600x?

I need to stick to evga and sfx as my cablemods are for evga


Just used this power calculator and it says system will draw a max of 597 watt

650w power supply came today its now all setup just been running some timespy and the division benchmarks never hit the power limit according to msi afterburner. Palit 3090 and 5600x plus water cooling setup

so all good so far

Is the 3090 a 3 x 8 pin or 2 x 8 pin?
I've used a 650W PSU with a 3090 FE and 5600x with zero issues. A 2 x 8 pin PSU can pull 375W maximum while the 5600x pulls 95W, giving you 180W or abouts for everything else. If a 3 x 8 Pin you may need something more powerful as this can pull an additional 150 watt potentially

The palit 3090 OC is 2 x 8 pin
