750W psu enough for my config/planned upgrade?

Hi peeps,

I recently pre-ordered an Nvidia Aorus 3090 Master and I will be using it within the below system - my main concern is that my current PSU is not going to be enough and that I should upgrade to 1000w:

ASUS ROG Z390-F motherboard
16GB Dual Channel HyperX 4000mhz
I7-8700k @ 5.2ghz (stable at 1.385v for the past 2 years, avx-4)
NZXT x62 kraken AIO cooler (4 x fans on it)
3 more corsair ML fans around the case
Some sensible 12v RGB lighting on the case

(current GPU: Strix 1080ti OC - boosted to 2.1ghz clock)

My current psu is a fully modular Corsair 750W - I do not think it can carry the 3090 and my current config - should I upgrade to 1000w? What are your thoughts? Would appreciate any input on this - thanks.

Should be ok if you're running at stock although if you plan to overclock then a stronger psu would be good idea.

Yes I think your PSU will be fine with your i7 and 3090. You don't need a 1000 watt power supply.

Yeah fine at stock. Which Corsair? Not all 750w corsairs are equal.
