I'm going to make a computer. It's going to be used to play games from time to time too. With the specs below, what type/size of power supply is needed?

EVGA GeForce GTX 660Ti

Nzxt Technologies Phantom Case

Western Digital Caviar Black 1 TB SATA III 7200 RPM 64 MB Cache Internal Desktop Hard Drive

Intel 330 Series Solid-State Drive 120 GB SATA 6 Gb/s 2.5-Inch

Intel Desktop Motherboard LGA1155 DDR3 1600 ATX BOXDH77KC

Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz

Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155

Thanks

For a system using a single GeForce GTX 660 Ti graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock you are trying to achieve.

Oh thanks! I was looking at the "CORSAIR CX500M 500W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply" which was in that link. Is that one fine?

The Corsair Builder Series CX500 ( SKU# 75-001667 / CP-9020047 ), with its maximum combined +12 Volt continuous current rating of 38 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 660 Ti graphics card.

I would also look at swapping out the Intel board for one by another manufacturer with a Z77 chipset. Asus, ASRock, Gigabyte and Zotac are good ones to look at.

Yeah, I think i should go with Gigabyte instead. The "Gigabyte Intel Z77 LGA 1155 AMD CrossFireX/NVIDIA SLI W/ HDMI,DVI,DispayPort Dual UEFI BIOS ATX Motherboard GA-Z77X-UD3H" looks like something promising.
(Thanks for the help so far!)
