Both Corsair SFX-L noise levels doesn't look good. Compare it to a Rog Loki 850w which has an A noise rating(Which is better than the SF750!)

I'm currently using a corsair SF750 to power my 4090 undervolted to .875 2550hz 100% PL. Power consumption is at 235w max for GPU. Only losing 5-8fps on Witcher 3 with everything maxed and rtx on.

I don't think you'd need a 1000w unless you plan to overclock, underclocking to .95 2750hz 100% PL +1500 Memory clock already performs better than stock settings with a max power consumption of 320w. I tried benchmarking at stock and reaching 400w and PSU is still holding, though I'm using a 5800x3d with -30 PBO2.

I'll probably upgrade to a 1000w PSU if I decide to get the 7 series x3d.

edit: stress testing was done in Haven benchmark.

Timespy gave me:
300w for 0.875 2550hz 100%PL
360w for .95 2750hz 100%PL +1500 memory
