For that price just buy a server PSU with breakout board. Check the link below...you will get a 1.2kw PSU thats platinum efficiency rated (94% thats about as high as you can get for a PSU) for way cheaper price.

This thing can power 5 apollos in turbo mode.

And they are selling these (slightly less efficient 750 watt version) for dirt cheap...just the breakout board used to cost $35
