Should be plenty, assuming it's of decent build quality.
Corsair subcontracts its PSUs to other manufacturers and I don't know who makes that particular Corsair model. Corsair sometimes uses good manufacturers like Seasonic and sometimes uses middle of the road outfits like Channel Well and Flextronics.
A quick Google says that card uses a max of 108 watts--I don't know if that's accurate.
I have an i5-2500 CPU system with 3 hard drives and no video card---it never uses over 150 watts when pounded hard, including the monitor.
So, if 108 watts is accurate for the video card, you probably would never use above 300 or so. In which case a good 500 watt PSU would be fine.
