If you use a Kill A Watt as recommended, then plug only your PSU into it and then multiply the reading you get by .90 to estimate 90% efficiency. Or, .85 for 85% efficiency for Bronze. The result will be an estimation of how much power your computer is pulling from the PSU.

It's a computer!

The XFX550W will be fine i had one its a great PSU i had at the time a 3570 @ 5.0GHz and a 7970 @ 1200 core not a single problem with that in games, for benchmarking maybe you will push it close but for 24/7 use i doubt you reach 450w

As everyone else has already stated, a good 550W PSU will be enough for a GTX 780 SC with mild overclocks.
