Corsair SF750 enough for this build?

[steverebo]

Ok so I just bit the bullet and grabbed an rtx 3090, I run an micro ATX build in an O11D mini and my psu is the corsair SF750. Is that enough for my build:

ASUS RTX3090 TUF
Ryzen 5800x (soon to be 5800x3D)
Gigabyte B550 Aorus Pro V2
2 x 8gb crucial ballistix 3600 C16 (will be adding an extra 2 sticks of this)
7 x noctua NF-F12
2 x noctua NF-A14
Soundblaster X3

On a side note my case does allow a second psu

Most definitely will be fine, I can tell you from personal experience the 5800X3D only gets to around a max of 90 watts under full load and in games the majority of the time chills at 60 watts.

The 3090 you may see around 360'ish watts at full bore so 750 is completely fine.

The 5800X3D can get a littler warm though, Not HOT but you will want to make sure your cooler is decent.

Thats perfect cheers, Using an nzxt 280mm AIO with upgraded noctua fans pulling fresh air from outside the side of the case so temps should be OK I think

Im running a 3090ti with an 11900k and under heavy load the total power read on the PSU is barely over 500W.

Yeah. Lower the power target, undervolt it a bit and so on. Should be more than enough.
