Hey guys so I have the following parts sitting in my closet ready to rock. Just waiting on my custom PSU cables from pslate.

Sliger SV590
Intel i9 12900K
Asus Strix Z690 ITX
Crucial 4800 32GB DDR5
Samsung 1TB 980 Pro
Samsung 2TB 970 Evo
Asus RTX3080 TUF
EK AIO 360 Basic with x3 Noctua fans
Corsair 750W SFX Platinum PSU

I am a little concerned after reading online that this PSU might not be enough for my system. What do you guys think?

750W will just be enough. Tight depending upon overclocks of the CPU and GPU. Running stock should be no problem.

I'm running my 12700K rig with RTX 3080 just fine on my 750w PSU. I game all the time and it's no problem.

Yes unless you overclock everything then it might get close. Personally, I would get a 850w so that it's never getting close especailly as the psu ages and potentially gets weaker.

It might be tight depending on the PSU, but that PSU should handle it no problem. From what I've seen, that PSU could probably be rated higher than 750W anyway. I ran a 5950x and a 3080 on a Silverstone 700W Plat with no issues.

I'm using a quality 10yr old 750W with my 3090 + 10700K build and its fine.
But if I were to get a new PSU it would be 850W with a 10yr warranty at minimum, good way to save money in the long run and get the best quality power delivery.
ie Seasonic Prime Titanium.
