Buying new CPU. Is my PSU strong enough?

[Rixxz2]

Title explains it. I'm thinking about buying this CPU:

[b]AMD Phenom II X2 550 Black Edition 3.1GHz[/b]

And my PSU is a 500w from Antec.

So, does it have enough cream to power these components without exploding?

CPU: AMD Phenom II X2 550 Black Edition 3.1GHz

GPU: Ati HD 4770

3 gb ram

A harddrive

A dvd rom drive

Yes

CPUs often go down in power usage every generation, unlike GPUs. I don't think you'll have any trouble.
