I ask this because I've already built my build, and am just lacking graphics. I also am a bit pressed for money.

The GB website (http://www.gigabyte.us/products/product-page.aspx?pid=4121&dl=1#ov) advises: "System power supply requirement: 500W", but I've been recommended this card by someone along with the PSU when I asked for build suggestions a while back. Unsure if the person who rec. me overlooked this, or if the 500W on the website is just there to be safe. I do plan to overclock, but if I don't have to now, I can in the future where I will be able to purchase a PSU with higher wattage. This is just for now.

Here's my build:

CPU: Intel i5 3570k
CPU cooler: Noctua NH-D14
Mobo: GB GA-Z77X-UD4H
RAM: G.Skill Ripjaws 8GB (2x4)
Storage: Samsung 840 Pro 256GB
Storage 2: Western Digital Caviar Black 1TB 3.5" 7200RPM
Case: Thermaltake Chaser MK-1
Optical Drive: LG GH24NS95
PSU: Rosewill Capstone 450W
