Choosing Power Supply

[khainfo]

Hi, this is the list:

 

Part List

CPU AMD FX-8350 BOUGHT

Motherboard Gigabyte GA-970A-DS3P $54.99 *

Memory Corsair 8GB BOUGHT

Storage Western Digital 1TB 7200RPM BOUGHT

Video Card Asus Radeon HD 7970 GHz Edition BOUGHT

Case Cooler Master Elite 431 Plus (Black) $14.99 *

Subtotal: $891.43 *

Mail-In Rebates: $60.00 Total: $831.43

Estimated Wattage: 494W

 

 

 

Im planning to buy COOLER MASTER eXtreme Power Plus RS-550-PCAR-E3

Is it enough? I think the GPU need more power than normal 7970. Does this power supply have enough connectors for my system?

ATX12V or ATX? what type of PSU i need?

 

I choose that mobo because it has internal USB3.0 header. But it's 970 chipset, will my system perform at max?

 

I dont want to buy expansive PSU, Chasis etc, because I invested more on GPU and CPU.

 

I don't plan to do crossfire.

Thank you very much for helping me

I would get the XFX Core 650W:http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014 You could get a 550W version of this but  your overclocks will be limited.
