We get this question A LOT. Here's a guide we like to give people when suggesting a PSU for people who don't want to run the brand new APW3++ (which also supports 110v now):
Normally, we'd recommend the EVGA SuperNova 1050 GS, but they're out of stock almost everywhere. The EVGA 210-GQ-1000-V1 is a good substitute though.
- Obviously, your PSU must have at least nine 6-pin PCIe connectors. Yes, the 8-pin (6+2) connectors work too.
- Always plan to use 80% or less of the total available power when using a consumer-grade PSU. If you need 800W, then purchase a PSU capable of 1000W or higher.
- Only use PSUs that have a single 12v rail. Mining devices require very high amperage and cheaper PSUs can't provide the full amount over all of their connections. PSUs with a single 12v rail can supply their full output through any of their 6-pin PCIe connectors.
- Only use PSUs that have Gold or better efficiency ratings. Efficiency matters a lot in the long run unless you have free power.
- Don't forget that consumer-grade PSUs do not "turn on" without jumping the right pins on the 24-pin ATX connector. Here's a quick how-to. I prefer to use a PSU tester instead for aesthetic reasons.
- Always be aware of your circuit's maximum amperage as well as how many amps are being used on the circuit in total. Remember, Watts = Volts * Amps, so 800W / 110v =7.27a.

Seems interesting. Are you an specialist in this field?
