Yes I'm using USD
Even the spread, you would run 5 less riser cards and the 675 Watts is going to save you >$2.50CAD/day ($912/year)
Plus you will save on the cost of the power supplies, not needing as large of wattage nor will you need 2 circuits. The two 850s will run on a single 20 amp safely
I can power 8 1070s, 8 risers, cpu, mobo, and ssd with two 850w g2 evga?
How should I safely power the risers? Split it all evenly?
I have 6 pin risers coming that come with 6pin - sata adapters.
Power the risers via the sata ports on the psu's?
