Will my Kingwin 550-watt 80+ Gold PSU be abled to handle an AMD X6 1100, and two 6870's, and 16GB RAM? I have one SSD, one HDD, and one opty drive...looking to expand on my current new build...from the looks of it, it will work as per some charts I have seen...I am just trying to make sure as I have seen a lot of the machines on here running 800-watt and above...

A reference version of the Radeon HD 6870 has a Maximum board power of 151 Watts (i.e. 12.6 Amps from +12V rail).

Two Radeon HD 6870 in CrossFireX mode would draw a maximum of 25.2 Amps from the +12V rails.

The Kingwin Lazer Gold Series LZG-550 is able to deliver 45 Amps on its single +12 Volt rail.

You have enough DC output capacity on the +12 Volt rail to handle it.
