I'm having a hard time deciding between the Antec hcp-850 (with mulitple 12v rails) vs. the Corsair AX850 (with one 12v rail), which I see has won some awards. It's for a video editing work-station. I'll be using one graphics card - Nvidia gtx 560ti or gtx 570. Any thoughts about which is better and why? Thanks.

For a single GPU, you don't need anywhere near that much wattage, but either one is good.
as my buddies said,850w is overkill.but,FYI antec hcp 850 is made by Delta and AX850 is made by seasonic.both are top notch quality,you can't go wrong with delta as they have a really good history but i am partial to seasonic.
