Wow, sorry. I was just giving an average efficiency.

So then here are the new numbers:

925 at 88% efficiency is 814W.

727W at 88% efficiency is 639.76W.

The peripherals along with the I7 950 at 4.34GHz give it some higher output than what the OP has, so the OP will be fine... it won't be that high for him, and I doubt he'll stress the system remotely close to that. These readings represent an approximation to the maximum threshold a system might give out at any one time for whatever reason.

Was the Kill A Watt only reading from the PSU's power cable too?

Yes. I can also re-run the tests on Tuesday. The cards are now with an I7 2600k system with a different PSU and latest drivers.

You have a lot of attitude for people that are calm and responding perfectly fine.

Click the link in my signature. I got a guy to run 3 480's heavily overclock with high voltage and with furmark, he pulled just over 1KW.

I think something is wrong on your end.
