Hi, my power supply has 2 12V rails with 21 amps each.
I believe this equates to around 250W for each rail.
This is apparently barely enough for 2 new Radeon R9
280X... I want to buy a Radeon R9280X now and buy
another one for crossfire in the future. What I want to
know is if I could maybe reduce the power output by
underclocking the 2 cards. Also, I have an i5 4670k and
a samsung 840 ssd. On the power supply:
3.3V -> 24A
5V -> 32A
12V1 -> 21A
12V2 -> 22A
Thanks!
