Looking for some last minute advice / approval

So, I have already pretty much figured out what I wanted from my PC, which comes to $699 after rebates, which fit my budget perfectly. This is my very first attempt at building a gaming PC and, I think everything is compatible and what not, but it would be awesome if someone could skim over the parts below and let me know for sure before I go ahead and buy everything. One major concern id like to have addressed is if my specific PSU has enough juice to fire up the sapphire 6870 and the processor safely. I don't plan on any Overclocking either. So, here is the parts:

COOLER MASTER Elite 431 Plus

Intel Core i3-2120 Sandy Bridge 3.3GHz LGA 1155 65W Dual-Core

CORSAIR Builder Series CX500 V2 500W ATX12V v2.3 80 PLUS

SAPPHIRE Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP

ASUS P8H61-M LE/CSM (REV 3.0) LGA 1155 Intel H61 Micro ATX Intel Motherboard

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

Western Digital Caviar Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5"

ASUS 24X DVD Burner
