Topic: newbie here in need of help with power requirement (Read 639 times)
Hello, new to all this and want to get all my rigs up. I am starting with 25 5870's and running them on the gd70 msi boards with 1200 watts psu's. I only have 100 amp service at my house and don't want to blow anything so I wired a whole new panel fed off a 60amp from the original box and running 220 instead. My new breaker box has 8 20amp double pole breakers so someday, when I get more dough for cards etc, I can run eight machines. My rigs should pull approx 5 or 6 amps (I think) each, so I ran 20 amp breakers and 12-3 wire for each machine on their own circuit. How many machines can I run like this on 220 before I start pulling too much power from the rest of the house, or is that even possible. I figured running 120 and pulling 10 amps per rig would kill something fast. Any advice on rewiring my psu's to 220, do I just change the plug end or is there more I don't know as they are supposed to autoswitch according to manual. They are INWIN commanders and 1 Corsair ax1200. Thanks for any advice.
