Which PSU for me: XFX 550 or 650?

[Gfreding]

I'm getting a new PSU, and cannot decide between the XFX 550 and the XFX 650, since the 650 is only 10$ more.

My system:
CPU: i5-3470
GPU: Radeon HD 7950
Mobo: Gigabyte GA-B75M-D3H
RAM: 8 GB Corsair Vengeance 1866 Mhz

Would getting the 650 decrease the load enough to make it last that much longer? Thanks

550 is enough!!!!!

XFX, good choice. I would just spend the extra $10 so you have the option of having extra power if needed.
