BSODs on Radeon 7950 when it goes into power save

[nsafreak]

The title of the thread pretty much says it all, what I'm trying to determine is whether I have a bad card or if it's my PSUs PCIe feeds that are causing the problem. Essentially if the card goes into a power save mode (I have it normally set to 15 minutes of inactivity) shortly thereafter the display driver will crash, not be able to reset and then BSOD. I currently have the 13.4 drivers installed but I have tried the 13.9s and 13.11 drivers as well with the same results. So I'm trying to determine if I should go out and replace the PSU or if that's a waste of time and I should just contact Gigabyte for a RMA. The card stays well within temperature specifications when playing any game be it BF3 or Hearthstone I don't think I've seen it go above 59 degrees Celsius under a full load. So that makes me hesitate to think that it's the GPU and think it's the PSU instead. The PSU for reference is a Corsair CX500. So what do you folks think, is it worth my time to replace the PSU or should I just start the RMA process with Gigabyte? The card is less than 6 months old and has not been overclocked at all. If it helps at all here's the whocrashed analysis:

these bugs might be bios related (and/or chipset). The same problems plague pass-through and virtualization as well. (one vm will reboot and cause the entire esxi server to blow up). It's buggy power management code .
