I have an old rig and a new rig, the "old" one is using a previous generation AX850 (the ones with the gold writing on the side, not the red), and a new RM 850.
I want to add a second graphics card to the rig with the AX850 in it, but the PSU cables that split up in two 6+2 pins for PCI-e have 12 pin connectors on the PSU end, whereas the same cable on the RM850 has an 8 pin connector on the PSU end, and splits off to 2x 6+2 pin.
They're both Corsair power supplies, and as far as I know they both use a 12 volt rail, but would it be safe to connect the cable from the RM850 to the AX850?
