I think it can handle it, but for the sake of future-proofing, you could go for the 600, maybe even 620/650, depends on the price. If you ever decide to upgrade the card or do some overclocking, you don't have to worry about the PSU suffering a meltdown.
Like I said, I run 520 and it's fine, your CPU would use about 30W more. I've pushed my CPU to 3.4GHz a few times and it still ran fine, voltages stable, though the PSU started putting out quite a bit more heat under load (hence my concern about upgrading).
