Unless my knowledge is extremely outdated, it's never a good idea to rest any component on the OUTSIDE of an anti-static bag. You'd be better to lay it on a cardboard box.

You would think they would be keyed to prevent this, but they're not. At least, they weren't when the PCIe was 6-pin and the CPU one was 4-pin; haven't checked whether this is still the case on systems with more pins on the PCIe and ATX power connectors.
Anyhow, this has the effect of grounding out one of your +12V rails, which can result in exactly the symptoms the OP is describing.
It's a long shot, but definitely worth mentioning.
