FE 4090 what PSU is required please

[beerglass007]

Hi

Currently have a 3080 10GB and just got a 4090 FE

Have a 58003D CPU and 750 Watt gold SeaSonicPSU, will that run the 4090 FE or do I need another PSU

Thanks

4090 is 450w and can use up to 600w when over locked.
5800x3d can use ~140w

750w PSU is cutting close

In TPU's review of the 4090 FE, the average power consumption was less than 10% higher, so I'd give it a go.

Currently running a MSI 3080 which on their web site is 330 watts. When I run it gaming the total PC is pulling 500 watts, so adding a 4090 which is rated at 440 watts should add another 140 watts making it a total of 640 watts ?

If you don't do any overclocking you might get away with it. A 1000W PSU is very cheap compared to a 4090 though ..

Yes, probably, but I'd try what you have first and then if it doesn't work, pay the extra £30 for the 1000 watt A1000G PCIE5 version. Going from 750 to 850 for £130 seems a bit silly to me.

I'm okay on a gold 850W
