4870 amp reqs

[Gk1]

I've decided on getting a 4870 for a new build and want to know what the amp requirements are for it. Also should i go with a single rail or multi rail psu solution

A 4870 needs about 11 amps. I have a preference for single rail PSU's.

The quality of the PSU matters, number of rails does not. You will need a PSU with at least 2 6pin PCI-e connectors.

Thanks i've read about the pci-e connectors but i was just curious about the amps so i would have enough
