I have built a dozen computers in my life and always used a ATX PSU, Never a Server PSU. I never been around a server yet. Iam just a PC gamer/Miner.

Anyway's i have a few questions?

First What is a good Server PS? I want one for X7 RX 570's, Would a 1200W Server PSU be enough?

Also, on these Server PSU's Do i need to run 220V to get above 1000W output ? What is the Amp limit on 110V ? I know my circuit breaker is 15A for 110V. So does this mean i can run only one 1200W=12A on this circuit breaker ? " Leaving 3A's for other stuff like TV,Fans,Lights,ETC

Finally which breakout board is recommended and Pico ATX adaptor?

I want to run everything off the server PSU, Also my CPU needs a 8-pin CPU plug, All i seen on the ATX pico Adaptors was a 4 pin Cpu, Would i just need a 4pin to 8pin cpu adaptor ?
