Hi ninjacoins,
it depends if the Vega is 56 or 64, the rigs are mixed with random number of each - each rig has 7x vega and HP DPS-1200FB server power supply, and power consumption at the plug is 1270-1350W.

I just ordered PLATINUM server power supplies that I got for great price on ebay, i hope I will drop the consumption by 100W on each rig by replacing all PSU, I calculated I will return the price of power supply in 90 days and have spare power supplies if something goes wrong, I will update here on monday when they arrive
