What PSU will I need?

[K_Higgins]

Well I was wondering what psu I would need for my first build. Here are the specs.

• Zalman Z9 Plus
• Phenom x4 955 Black edition
• Corsair XMS3 8gb 1600mhz RAM
• USB wifi stick
• Toshiba 500gb HDD
• Saphire Radeon HD 7770 OC
• Asus AM3+ 760G + SB710 DDR3 ATX motherboard

I was thinking about getting a corsair CX500 V2 psu but not too sure if it will be enough. I would really appreciate any help.

AMD Radeon™ HD 7770 GHz Edition

500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended

You should be fine with a 500W power supply. Card vendors usually allow for plenty of head room with their specifications.
