Was using a direct pass through wattage meter from the wall. I do believe someone had mentioned the device previously in this thread, a kill-a-watt, meter.

edit: the 90% load was during stress testing using kombuster and prime 95.

Did you multiply the reading by .90 for estimating 90% efficiency?

I am probably going to sound like a noob for probably doing this wrong, but what i did was i multiplied 700 by .8 for my 80% mark, and when i got a reading of about 620w i divided by 700 to get around that 90% mark.
This was stress testing with just the cpu overclocked and gpus at a stock core of 1200 and stock memory. I wanted much more headroom for down the road. more hard drives and higher OC on the gpus, and potentially another graphics card. hence why i went with 1050W.

Yeah, you did it very wrong. The PSU's efficiency has nothing to do with its output capacity.

Please Pm me with the proper way of calculating power output vs efficiency, I'm always eager to learn the proper way of doing thing with computers. I know a lot about hardware having worked with computers for 6 years but i am still learning. I am not so bold as to say i know how to do everything either.
I thank you in advance for the information.

If I PM you, then no one else will be able to benefit from it.

 

Efficiency: if the PSU claims to be 80% efficient, then multiply wall meter readings by .80 to estimate how how much power the computer is pulling from the PSU. If it claims 85% efficiency, then multiply by .85, and so on.

 

There's nothing more to it than that.

bah! just go all out and get another 1200w so you can watch the lights flicker across three neighbouring states
