Very high current power supply (2012)

Blade Chassis power supplies are cheap used, very efficient, and will do nearly 200A at 12V from 240V input.

Search HP 500242-001.

I'll second that, I believe people use them for RC chargers sometimes. I used the HP DPS 600PB for trying to drive a number of peltiers. I think mine only did less than 50A, will look into the model you mentioned.

I assume none of the blade PSUs also output 5VDC?

If you can pick up a DS850-5 it'll give you 12v @ 70A and 5v @ 4A. It'll have noisy fans that run constantly, though.

Most applications of such a power supply (like blade servers) would have a bunch of secondary SMPSes generating lower voltages from the 12v rail.

I have 5 at home, exactly from a Blade Center.

Any idea what I can do with them?
