[SOLVED] PSU for SFF Ryzen & 3080 Build

[tom_taylor97]

Hi,

Planning out my new pc build and trying to build small form factor but I'm a bit unsure about my power supply choice.
I have used various PSU calculators which all gave different results.
The parts I have been looking at are;

Jonsbo A4
Ryzen 4 processor. 3700X/3800X equivalent
Gigabyte Aorus Pro X570 Mini ITX
Corsair Vengeance (3600)
ADATA XPG SX8200 Pro 1TB
RTX 3080
Corsair SF 750W
EK-AIO 240 D-RGB

My issue is that from what I can see, SFX power supplies only go up to 750W. I know that Nvidia reccomend a 750W psu but I was hoping to OC my processor while possibly undervolting the 3080 if I were able to maintain clock speeds.
Do you think overclocking this build with a 750W psu would be too much? or is there an 850W SFF psu that I have missed?

Many Thanks!
Tom

Silverstone has an 800W titanium model (tier B) but the Corsair SF 750W is probably the better of the two (tier A).
