PSU for RTX 3080 [Help]

[Waqas409]

Hi,
I need help regarding the Build below.
I have tried different online Calculators, especially the FSP one and they have recommended 650W overall (Screenshot attached below)

is 650W is enough for the build below or 750W or 850W.


Specs:
CPU: Ryzen 5 3600
GPU: Evga RTX 3080 ftw3 ultra
RAM: 32gb (8x4 corsair vengenace lpx 3600mhz)
Motherboard: MSI B450 Tomahawk Max
PSU: <Needed>
Fans: 6x 120mm Fans
Drives: 3x Sata SSDs, 1x 7200 RPM 1TB HDD

650w might be OK, but with the transient spikes of the 30series cards I would recommend a 750w

If you are planning on upgrading to a particularly beastly CPU in the near future, you can go higher if you'd like.

a 750w maybe more for efficiency. But a good 750w is good for that I figure

some people are recommending me 850W not sure why! 
that is why im really confuse between 750W or 850W

650 watts would definitely work but you could get a 750 watt if you plan to upgrade your pc a lot.

Recommended PSU by NVIDIA for the 3080 is 750W so that should be the minimum to go with.

You will always get widely varying recommendations for this kind of question. The answer depends on the quality of the PSU. Nvidia recommends 750W because they are trying to be safe with low quality units. Your GPU has a max TDP of 450W if you crank the sliders. The CPU might do up to 100W.

 

A quality 650W unit seems reasonable to me for that build.

Yeah, as long as you pick a quality unit.

 

Choose something from tier A:
