Ya, I did some research on these, you're right on the power draw.
For reference, these are essentially a pair of black widows in a single case. Each of my widow boards pull about 250 watts at 120v. When I first got mine, I found the fan pulling air from the back of the unit which, in my opinion, seems wrong. One of the first things I did was flip the fan on the chassis, blowing hot air back into my hot aisle the way it was intended. I also found the wire to be rather thin, and I replaced with 14awg with crimped terminals. You're wiring options will vary based on your psu. One thing I learned for sure it's that it's better to power each board separately than using two ends from the same lead coming from the psu, just too much draw. I'm looking at you EVGA.
Those blade center psu, or the ones from quakefiend420, I keep seeing on here would be great for powering these, with replaced wiring into the chassis.
If I had the available power in my mine, I'd pick up a few of these. They are solid miners, even if a bit power hungry. For those that are ltc mining, keep an eye on the pending block reward halving as part of your ROI calculation.
