4 pin to 8 pin adapter OK to use ?

[WT]

I just bought a GTX280 card for my main rig, but had forgotten to check on whether my Fortron Epsilon 600w had the proper power plugs.

Looking online, I realized it didn't have the 8 pin power lead necessary, so I decided to swap the PSU with the newer unit (OCZ GameXstream 600w - identical to the Fortron other than the fact that it offers the 8 pin power lead) from my spare gamer rig.

Now the problem is that the ATX supplementary power leads are much shorter on the OCZ unit, and it will NOT get even close to plugging in. I found I had a 4 pin to 8 pin (8 pin goes to the board) adapter that give me enough length to plug it in.

Is it safe to use that ? One of the 2 CPU leads will obviously not be plugged in, but I am hoping that the adapter is what I need.

I don't see why it wouldn't work. If you have a 4-pin ATX12V lead from the PSU, and were just going to plug it into half of the 8-pin ATX12V socket on the mobo, then there's really no difference, if there's a cable in-between, that I can see.

Thanks Larry. I left the PC off all night in fear of powqering it up before getting any replies. I am also fiercely opposed to ANY adapters or cable extenders, but in this case I see no other alternative other than to buy a PSU with longer cables. My plan was to go with a BFG 800 eventually, so I'll boot it up tonight after popping the GTX card in.

I know there are adapters to take care of the missing 2 pins for the 8 pin PCIe2 power lead, but I would have had to order that one and wait a few days for delivery on it, so I did the best I could with what I had.

Looks like BFG already covered the PSU power lead issues with the adapters already in the box, one for both the 6 pin and the 8 pin leads for the card. I could have saved myself 1.5 hours by not swapping the power supplies out (quality cable management is NOT easy to reverse, my friends), but again, I stress that I did not want a bunch of half assed adapters hanging loose in my case, so what I did was the right and true way to deal with the problem.

Now the only adapter I have is the one to the ATX +12 aux on the board. With the extra 4", I was able to route it under the board tray which was better than it was strung across the board and tucked under the video card. I'll put the new card in and flip the switch tonight and hope for the best.
