I need to order another psu for my 2 ants on the way. Would you recommend a single 500w for each or just going with a 850 corsair?
Better efficiency psu will save you some on the power bill if that's a concern for you. For me RM1000 saves roughly $6-7+ at 0.22 kwh in New York ... but its costly to buy. When I'm done with mining, this probably goes into a future desktop rig I'll build or an S2
