Default PSU For My Gaming Rig

This is my first attempt to build a computer and I just need a little guidance. Heres the specs.......

Gigabyte GA-785GMT-USB3 mobo
Apevia X-Qpack 2 Cube Case
8gb DDR3 1600 Dual Channel Memory
Phenom II x4 965 Black Edition CPU
Sapphire Vapor X Radeon HD 5770
Seagate Barracuda 750gb SATA Drive

After that im just gonna get a cheap burner and card reader. I dont think the 500W PSU in the case will be enough but my mobo takes ATX 24 pin or
ATX 12V 2x4. Does it matter which type of psu I use and should 750W be enough headroom. Thanks for any feedback.

Your PC should run with a minimun of a 450 watt power supply and if you plan on possibly adding another 5770 then a 650 watt power supply is the minimun. These wattage numbers are really just a general number to be considered because not every 450 watt power supply is the same. Most of the better Brand Name Manufacturers will exceed specifications when rating their products while most of the Generic/Cheap Manufacturers will manipulate their actual numbers to barely meet a rating the product does not deserve.

This would be an Excellent Upgrade for your PC with a single ATI 5770.

This will work with (2) cards.

If you just want more power then this has more than enough

I'll add the hx line of corsair too, is a good option. Theyre just modular and multi rail.
