Radeon 6870 and Antec GreenWatts Green 430D 430 Watts

I'm having a new PC, however, I am kinda worry about the PSU if there will be any problems.

Here's my stuffs.

2. ASUS M5A78L-M LX AMD Socket AM3+ Motherboard - Micro ATX, Socket AM3/AM3+, AMD 760G Chipset, 1866MHz DDR3 (O.C.), Radeon HD 3000 Graphics, SATA 3.0 Gb/s, RAID, 8-CH Audio, Gigabit LAN
3. Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power
4. SAPPHIRE 100314-3L Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card
5. SAMSUNG CD/DVD Burner Black SATA Model SH-222AB - OEM
6. Seagate Barracuda 7200.12 ST3500413AS 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
7. Crucial Ballistix sport 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model BL2KIT25664BA1339

Do you guys think there will be any problem? I am probably gonna use this pc for gaming (starcraft 2, bf3, diablo3, SWTOR, etc.) and would be running in them for several hours a day. Please suggest. Thank you.

    That power supply will be enough for a single 6870, you only need to go higher if you intend to Crossfire down the road or if you want a little more headroom for overclocking. Everything looks fine, that machine will be able to deliver good gaming performance. It probably won't be able to max out BF3 at 1080p, but it will perform quite well in all but the most demanding titles. Even with the most demanding games you will still be able to get high settings, just not ultra/very high settings.
