Modern pc Power Supply's is ATX12V.
You need old (very old, and in this case definitely used) Power Supply's for AT computers . 250 watt have near 25A , 5 v line.

Interesting and cheap solution. The problem is that the miners use 24pin ATX connectors and those old connectors are 20 pin I think.
I think these old PS's are pretty loud though (this will be in the living room.)
Still a good solution, thx.

I'm pretty sure the 20 pin plugs will snap right into the 24 pin connectors. The only thing the extra four pins add is one more wire with 12v, one with 5v, one with 3.3v, and one ground. It is my understanding that all of the different power and ground wires share a common source. This makes me think the additional wires were just added to cover the extra amp requirements for different branches as the systems started requiring larger power supplies. ie....After derating 18 gauge wire for temperature it might only be acceptable to carry an eight or nine amp load. If you need to supply 15 amps you would either need to increase the wire gauge or use a second run of 18 gauge wire.

I'm sure someone more knowledgeable can step in and correct any errors.
