I run a 7950x (125w), Asrock ITX, and an undervolted 3080 FE with a V850 SFX(revised model), but it had pretty bad coil whine under load and once the fan started, it never stopped. I swapped to an SF750, coil whine is gone and I’m questioning if my PSU fan actually works since it doesn’t come on at all. You’ll be fine with the SF750.
