Can I use a PCI-e 6 pin on a CPU 4 pin socket?

I just switched the PSU on my server which has two 4 pin CPU power sockets, My power supply only has one but I have a 4 pin molex to 6 pin PCI-e that fits into it (although the little shapes on the ends are not all right, one of them should be a square but is the other shape, it still fits though.) I was wondering if I could use the 6 pin PCI in the 4 pin cpu slot, would that work?


EDIT: bought a molex to P4 adapter. No need for this anymore.

It should work, but if and only if (waving arms frantically here) you have a 6-pin to 4-pin adapter. Don't plug directly into the socket, even if it fits - you'll be firing the wrong voltages down the wrong lines, which could kill your motherboard.
