All 3 rails combined cannot exceed 385W, this gives a combined amp of 32A. Like I said, not just adding the amps on each rail.
Yes, yes, but still the amps noted on each rail can not be exceeded, if they are- the PSU will shut down. This W fooling-around is typical for PSU companies, trying to make their PSUs look more powerful than they are.
Although you may be able to deliver 32 amps on a rail without damagin anything, the PSU will (should) shut down, as the protective circuit for that rail allows ony 18 or so amps. Anything above that is considered short circuit. And I'm off to bed, hope I've been helpful.
EDIT: Anyway, as I said, on the 18A and 16A rails, a 6850 should be well fed. Just don't wire it to the 8A and you should be fine.Edited by ronnin426850 - 2/20/11 at 3:39pm
