Hooking up new PSU

post #1 of 5
Thread Starter 
Please go easy on me guys as I haven't built a PC for a while and am used to IDE cables.

I have just aquired a 'Coolermaster M700' modular PSU, and spent most of last night hooking it up inside my tower. Everything has gone well so far and is working fine.

Its just that on the PSU side there are two 6 pin PCI E sockets, but only one 6 pin cable to the GPU. I have plugged one into the first vacant socket on my GPU and taken the other from a spare 4 pin using an adapter to become the second required 6 pin. Is this method ok or should I get another 6 pin to 6 pin cable and use the remaining 6 pin socket on the PSU.

Hope this is not too confusing.

I think I understand

So you have a power connector spare on your PSU and on your GTX 470 but no cable to connect them?

I'd get a cable as soon as possible, or it wont be able to run at full power, or you might just get BSOD or something

if you used an adapter that looked like this you are fine. you are not undervolting your GPU. If not please take a pic so we can see what your talking about!

My PSU has 2 dedicated 6 pin sockets. I used a 6 pin to 6 pin cable for one of the sockets on my GPU, leaving one remaining socket to fill. Because the PSU sockets are slim and unique to this unit, I had to use one of the supplied cables and used a PCI Express adapter like the one in Killerxmaniac's photo.

I read that for any PCI express adapter useage, you have to plug two of the 4 pin connectors into the PSU for sufficient power. I have only plugged into one molex socket on my PSU for one of the sockets on the GPU. However the other GPU power socket is connected directly to a dedicated PCI Express socket on the PSU.

I think that I need to get another 6 pin to 6 pin PCIE cable to use the second dedicated PCI E socket on my PSU.
