The XFX power supply, which will not be used since the other died and I had to put it back in the old PC, has markings for either way too, but even upside down the 8 pin and 24 pin leads were still too short to route through the back of the case.
As previously noted, I've ordered the extension cables from newegg (along with the new power supply). I should be set, either way with the new power supply and extension cables.
