I wished there was a 1600w 120v server PSU instead of having to spend $320 on the EVGA.
Run 2 miners on 3 of the 1300 G2 would be less expen$ive.
As long as you don't mix PS on the same hash board, it should work - I ran 3x S5 (or 2x S5 and my SP20) on 2 1300s (or 2 Seasonic X1250) without issues, just make sure to power things up in the right order.
