Sapphire 4870x2 fitting question

[mcrustk2]

Hi.

I have literally just fitted my 4870x2.

I have a nrew 750watt Corsair PSU with PSI-E cables.

The 4870x2 has two sockets for cables, do I use 2 PCI-E cables? or does it need just one?

Use them both, it needs it.

Even the single core 4870 needs two
