Just how accurate are power supply calculators

post #1 of 3
Thread Starter 
It seems most people claim that a PSU can handle more than all of those power supply calculators show.

Accurate to the extent they are the worse case scenario for 100% usage.

pretty accurate

i tested my e5200 rig with gtx 460 and 2 hdd's in (no accessories).

I got
-299W from the antec PSU calculator under full load
-Measured 286W from the wall when running 3DMark for 20 or so minutes.

Id call that within margin of error
