actually - not great at folding. http://www.crazy-logic.co.uk/archives/795 yeah it'll do a WU in 2 hours but....
ppd/powerthe M600 server blade 23000/8.64kWh = 2662 points/kWh,the QC Core 2 Quad 6500/2.62kWh = 2480 points/kWh,the QC with 750Ti 38000/3.6kWh = 10500 points/kWh.
urm.... fully loaded, lots. Each blade is 360W and the fans on with 4 blades funning full pelt is ~800W
it has 6 PSU slots, each can be 2.3kW or 2.7kW i think, and i've got 4 installed. You can run all 16 blades off 3 PSU's. But the chassis has some power budgeting functions so if you loose PSU's you can do funky stuff like kill blades in a set order or reduce the power allocation to the blades i think.
I have one - but this needs a 1m deep rack, which i don't have. hey - i put it on its own wheel board not to scratch it
i actually use it to head my workshop from 6 to 22 deg (Deg C) with 3-4 blades running for an hour full pelt folding.
yeah i have it hooked upto a 32a circuit, but I calculate around 7-8KW on full load.
