A cheap power supply is not safe even if you do not overclock.

If you never plan to upgrade the video card, a 400CX would be enough.
Corsair 400CX (30 amp 12 volt rail)

I do not recommend the 450:
Corsair 450VX (33 amp 12 volt rail)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It doesn't have enough usable power compared to the 400CX

With nearly any single video card, I recommend the Corsair 550VX (41 amp 12 volt rail)

I have a 750 watt Corsair, but unless you are planning to upgrade video cards later, both of the PSU's are massive overkill. A good 550 is more than you need.

But of the two PSU's that you listed - Corsair by all means.
