Choice between 2 psu's for SLI

CAMILOGOD · Nov 9, 2012

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-details.asp?EdpNo=7195038&CatId=2533

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.

CAMILOGOD :

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.
