Question about the power supplies
I have a whole bunch of 300w power supplies extra at work
I was thinking I use 1 300w power supply per blade
So for my 1 antminers, I would use 4 of these power supplies?
What's the current draw per blade?
So I check they have enough power on the 12v line
Don't really care about power efficiency as our lease agreement at work includes unlimited power

No.
I had been provided some no-name thermaltake 600w for each blade... 5 of them have burnt out so far. Please don't skimp on the PSU. Why would you spend 2k+ on a miner and not the extra $20 bucks to get a quality psu?
