Mostly RX 480/580 8GB cards. Asus STRIX, Sapphire Nitro+ and MSI Gaming X. Also a Saphire Pulse RX 580 4 GB and a Nitro+ RX 570 4GB with a EVGA 1600 W T2 for the motherboard, all 13 risers and 4 cards VGA power on a 120V 20A outlet together with a EVGA P2 1000 W + G2 850 W for the rest of the cards on a 15A circuit. All the cards have a Polaris Bios Editor v1.62 'one click timing patch' Bios mod and I get the best result with the Sapphire Nitro+ RX 580's 30-30.5 MH/s ETH 875 MH/s DCR dual mining.

You are running 2475w at the wall
and have 3450w worth of psu's.

If I were to run 13 570's can I get away with 3 850w? Or 1 1000w and 2 850w?
