Got a new card (XFX R9 270x 2gb) and a new PSU (630w) which can go up to 730w. When I try to use this card my computer boots for a split, maybe one second, the fans just begin to start spinning, then shuts off completely. When the computer shuts off, my motherboard (EVGA 122-ck-nf68-a1) has an solid orange light that comes on. At this point I can't power on even for that split second again, I have to switch the PSU off and on to get the computer to boot for that split second. I tried using another rig with an older mobo and weaker PSU(550w), same thing happens only I get a squeal of power and no fans spinning. Some of my thoughts on what might be happening. The same thing was happening with my older PSU (600w) as well, which is the least likely issue. I also thought it might also be the amount of power coming through the pcie slot might be insufficient, looked into EVGA power boost. What else might be causing this?
Notes: PC boots fine with XFX HD 5770 1gb. And the other rig with its (gtx 260 896mb). The other rig that I tried the card in has this motherboard: ASRock A780FullDisplayPort. The HD 5770 worked fine with my 600w PSU as well.
