Just bought a kill a watt, am I doing this right?

post #1 of 3
Thread Starter 
Okay, just bought a kill a watt meter. Says my rig is pulling between 115-130w at idle(cpu @ 4ghz 1.26vcore/ GPU at idle clocks 157mhz 300mhz memory core). With CPU doing prime95 small FFTS and GPU doing msi kombustor(furmark) at the same time, it says it's pulling 450w from the wall. At that level of load on the PSU, the earthwatts 500w unit it about 82% efficient. This would mean that my components are using about 369w of total power. Does this seem right to you guys? This would mean, my little earthwatts unit is more than enough for a quad core @ 4ghz and an overclocked 5870 @ 1.21v 1000mhz core 1250mhz memory(both were overclocked during testing).

Also, does the 500w rating mean that the unit can pull 500w from the wall? Or that is can feed my components 500w of power after taking the electricity from the wall and factoring in efficiency?

correct ppl always over estimate PSU needs but its is better to over estimate than under estimate

it means it can supply the pc with 500w full load, it will pull about 600w from the wall factoring in 80%

Great to hear! Thank you for the quick response!
