Hey guys, I'm currently in the process of buiilding a new gaming computer and I had a quick question about the power supply I plan on using. Will my OCZ Fatal1ty 550W power supply be able to run :

MSI Z77A-G45 Intel ATX Motherboard

Core i5-3570K Ivy Bridge 3.4GHz Quad-Core

SAPPHIRE 100352-2L Radeon HD 7950 3GB 384-bit GDDR5?
 
I would say go with at least a 650 watt corsair TX650. Gives you some headroom just in case for upgrading later.
 
Thanks for the help! So a 650w PSU would give me headroom for upgrading in the future, but my current PSU will in fact support my set up. Correct?
