calculation power consumption of my pc...

[bubhead]

Hello, I have a 420watt psu.. It is rated to pull 115v/10a from the wall..

How do I figure how much it is actually pulling?

I have figured my components to only be using 65% of the 420watts.. Im thinking take 115 x 10 = 1150watts x .65 = 747.5 watts..

is this correct? if not how do i figure this?

thanks for any help..

It dont think it is actually pulling that much from the wall at all..

Use a clamp that tells you how much it draws from the wall

Where do i get, how much does it cost?

otherwise i think im going to make one out of an old power cord and a 1ohm10watt resistor, and use my volt meter..
