For example, an unspecified HP PSU measured in 2007:
BTW I'm making my measurements with a calibrated Xitron 2503AH (http://www.xitrontech.com/products/general-purpose-power-analyzers/#2503ah) with an external 500A precision shunt for the DC current.
Nice. I am jealous! We may rely on your for accuracy.
Let me know what numbers you find.
@Philipma, be careful when testing to 2500. I have not tested these boards beyond 2kW for an extended period of time. It should be safe, but try not to exceed 130C anywhere on the board.

no worries my tests will use 1 miner for each psu which will pull about 1200-1500 watts at the wall
I just have the
dps1600 1 with your board
dps2000 2 in a j4bberwock 4k board
dps2500 1 not set up waiting for your second board.
basically any of the above will only run 1 s-9
I will over clock and under clock. and take heat measurements plus give my pdu amp readings, but I do not think I will ever exceed 1500 watts at the wall on any of the above psu's
