I managed to get my hands on another gtx 560 and want to run it in SLI but need a new power supply.

I was thinking between either the

corsair tx 650

or

corsair tx 750
http://www.tigerdirect.ca/applications/SearchTools/item...

both say SLI ready and there is a pretty significant difference in price. Would the tx 650 be enough to run to gtx 560 cards?
Thanks

I would go with the 750watt for the 4 PCIe power connectors, the cards need 2 each.

For the same price I think this is better:
XFX ProSeries 750W XXX Edition (Silver) ($127 after MIR)

Better because it's modular, more efficient and has a lower minimum fan speed, so should be quieter most of the time.

You plug the cables that you need in to the psu as well as the hardware. Basically the cables are not fixed to the PSU.
