How much should I spend on a power supply? I am building a rig with 6 1070s and was thinking of buying a EVGA SuperNOVA 1600 P2 80+ PLATINUM. Any advice is appreciated.
I'm running 6 x 1070 and 7 x 1070/1070TI rigs on Corsair HX1200i PSU with no problems.
If you run your cards at around 125w, it would be 6x125=750 + lets say 100w system =850w.
850/1200=70% load on PSU, so there's room for another card.
HX1200i (platinum) should be under $300.
Also, get 1070TIs instead of regular 1070s : )
