I have LC5550 v2.2 and I wondering will it be able to power HD5850 graphic card, I know that requirement for GPU is 500W but I am not quite sure can it output enough power for it,
Thanks
That GPU needs a minimum of 40 amps on 12V line but your PSU has a combined 38 amps, its short of the required minimum, so it won't be able to power it.
