Converting 8 pin pci-e plug ti 6 pin

[dannybgoode]

Hi All

I have a Thermaltake Toughpower 700w - hard wired, not modular (unfortunately).

It has a 6 pin and an 8 pin pci-e plug but my 4870 is 2 x 6 pin. I have an old power supply that has a 6 pin plug on it also and being a bit handy with a soldering iron I am looking at a quick swap over.

My question is, on the 8 pin plug there are 3 x 12v and 5 x ground and on the 6 pin just 3 of each. Do i need to do anything with the 2 grounds left over on the 8 pin (eg attach them to a couple of the other grounds) or can they just be taped up.

Thanks all for your time.

If there is adequate clearance to the side of the 6pin socket on the 4870, you can simply plug the 8pin plug into the 6pin socket. Pins 1-3 & 5-7 of a 8pin plug match the pinout of a 6pin plug.

Going the soldering route, taping up the unused ground wires or soldering them to adjacent ground pins will work.

Thanks for your help - having already cut the plug off its the soldering route!!
