Ok so I posted this setup about a month ago but I changed a couple things. Just wanted to get everyone's opinion. My biggest concern is the PSU. Will it be able to power everything there? Also will it be able to handle any small additions later on? Oh and will I have to buy anything else to help with temp?
Case - NZXT LEXA BlackLine
Motherboard - MSI K9A2 Platinum
PSU - OCZ Fatal1ty 550W
CPU - AMD Phenom 9950 BLACK EDITION
RAM - OCZ SLI-Ready Edition 4GB
Hard Drive - Samsung HD642JJ 640GB
Optical Drive - LG Black 6X Blu-ray/HD Model GGC-H20L
Graphics Card - BFG Tech GeForce 8800GTS (G92) Already have this by the way
Thanks for the help guys
