Hi there,

I have a Corsair VS650W PSU which has 2x 6 pin PCI-E power cables that are currently taken up by my Radeon HD 7950 card.

I want to add a second Radeon 7950 card to the system, however I do not have any PCI-e power cables and wanted to use splitters.

So can I use a splitter on each of the current power cables to power up the cards? Will this cause any problems?

PSU will definitely support it as I checked the load before buying however I did not check the cables.

I'm thinking of buying 2 of the following:

If you use molex to PCI-e adapters you should be fine, not sure about spliters though.

Yes, you can use splitter but i'd recommend only two 7950 because each one of them uses a max of 225w

I could supposedly use molex adapters but then I would need 4 available molex adapters for an extra 2 pci-e pwoer cable, and I do not have that many molex available.

My main concern is with the cable degrading or melting if I put a splitter on each of the current power cables. Is there any risk of that?

Any good quality splitters recommended?

I've now purchased the splitters and will report back on how I get on.

I wonder if anyone had done such a thing previously and with what result?
