I am using 2 Coolermaster V850 to power up 1 Jupiter november batch.
All together is pulling 860-865 watt at the wall.
Waiting for the rest of the jupiters.
DON'T BUY LOWER THAN 1000 WATT PSU
With 855W at the wall a single V850 would be perfectly capable of running a November Jupiter.
I will be powering 3 October and 2 November Jupiter with 2x V850 and 2x EVGA 1300W.
