I don't have a Kill-a-Watt on hand, but its rated for ~650W at 66gh/s, so I'm guessing somewhere around 750W with the current overclock.

Sorry, only accepting offers starting at BTC25 for this auction.

ASICMiner Erupter Blades are going for 4.6BTC for 10-11GH/s currently, so this is quite competitively priced.
