hi,

 

I have a Corsair RMx Series RM750x will it do fine for AORUS GeForce RTX™ 3080 XTREME + intel i9 12900k? + Cooler Master ML360 Illusion Addressable RGB AIO CPU Cooler?

 

+ some extra case fans on top

Should be fine. If you would experience shutdowns then either power limit the GPU or then think about getting a 850W PSU.

I ran my system (see signature) with a ROG STRIX 3090, with a Corsair HX 750w for 2-3 months before getting the HXi 1200w. 

I do believe 750W for your build will be enough but I would still get a 850W

If the GPU is not OC'ed, and you leave your 12900K stock, and makes sure that your motherboard doesn't default to unlocking power and turbo aswell, then I believe you are fine. You will not exceed 750 watts.

Yeah, I think the 12900K uses like 120/150 watts at stock but when it is unlocked and stuff, it can pull 250 watts easily, if I remember correctly.
