https://pcpartpicker.com/user/sorrensmith/saved/1tVJ

This was my first $500 gaming rig I built myself and am looking to upgrade 

 

 

i5-3570k + XIGMATEK Dark Knight Night Hawk Edition/ with an overclock to 4.5Ghz 

Would Im using a 550w psu and wondering if i will need to upgrade that if i want to upgrade the cpu

no cpu's don't consume that much power even at 4.5 ghz. if you have 2 gpu's then use get bigger. (that's what she said.)

IMPORTANT UPDATE YOUR BIOS BEFORE YOU UPGRADE.
