I already purchased a 550w power supply from Newegg, and just realized it might not be enough.

I am going to be running a(n):
-XFX Radeon HD 6870 1GB (normal clock speed)
-Intel Core i5 2500k (OC'd to 4.5GHz)

Please tell me that's enough, please, please :(  .

550 Watts is plenty for that setup

Which 550 W PSU are you getting from newegg? Not all power supplies are created equal. A 550 W Antec unit will do that just fine, a 550 W linksys unit will die in a fireball.

550 watts could be enough, don't know, you didn't say which 550 watt psu, and it's about more than just the wattage.



Sheesh, I got redirected a couple of dozen times and it's already responded to.

For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

The OCZ ZS Series 550W (OCZ-ZS550W), with its +12 Volt continuous current rating of 38 Amps and with its one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system with a single Radeon HD 6870. There should even be enough reserve capacity to handle the overclocking of the i5-2500K to 4.5 GHz.
