Hello to evybody!
I currently own
XFX R9 280x card
AMD 955
AsRock 970 extreme 3
PSU is a LC6650GP3 , and I think is currently not handling the setup because I get sudden and complete shutdowns and the "Kernel power error 41" in the windows log while gaming (curiosly running 3D mark, or Passmark is fine..)
I think the cause is one of the +12V rails being over saturated and OCP kicking in, probably by the GPU.
The PSU specs are
+12V1 25A
+12V2 27A
max. combined 550W
total (with 3 and 5V) 650W
I measured the total power consumption from the outlet with a thinamajig I own and it peaks at about 330W while gaming. And that is the total from the plug so, including efficiency, the psu is outputting no more than 300W. That is way below the 550W of the 12V rails combined declared, let alone less than the 650W total.
(But even supposing ALL the power is sucked by the GPU a 27A rail should hold it!)
Cables are not colour coded for the diffrent 12V rails so I have no way of knowing which cables are which rail without tearing the thing apart. LC Power is not responding to my email (yet). Is there another way to find out?
Am I doing something wrong? Missing something?
