i switched out my corsair hx850 with a new corsair ax850. ( the ax is a smaller psus and fits better in a silverstone ft03.

well teh ax850 psu gets much warmer the then hx850 and my GPU's gtx580's in sli run about 10c-15c hotter now. All i did was a PSU swamp.

Is this ax850x a bad psu? i cant imagine a psu makes gpu's run hotter.
 
Of course it gets hotter. The fan doesn't run most of the time. The PSU is designed that way.
 
Probably the same reason. The extra heat from the PSU is heating up everything else in your case.

Yep. The radiated heat from the hot PSU plus, depending on your case's air flow design, the additional loss of airflow from one less exhaust fan running or running slower will usually affect internal case temperatures. A PSU is an oft underestimated/overlooked component of internal thermal management.

thing is the PSU isnt really super hot to really make both my 580gtx temps go up 10c-15c

I think you may also be remembering wrong. It's very unlikely that your temperatures have risen by such a large amount. Or perhaps you left a fan or two disconnected inside your case.

everythign is the same. im just wondering if these 2 gtx580's are really putting a load on this PSU at full load
 
I think it's because the fans on the HX were drawing out the hot air from the case.. whereas the AX's fans don't spin most of the time. It's like removing a fan.
