I just bought a ASUS M4A785TD-V EVO Motherboard running an AMD Phenom x4 965 BE and XFX HD6870, i don't plan on overclocking these really, but yeah. The PSU I was looking at was a XFX Pro 450W - http://www.cclonline.com/product/55411/P1-450S-XXB9/Power-Supplies/XFX-Pro-450W-Power-Supply-Unit-Core-Edition-/PSU0202/ because i'm trying to stick to a tight budget, I was looking at a bundle deal with the Coolermaster GX650w, but it's got some pretty crummy reviews, But anyways, I was looking for something around the £40 mark, would this be enough? Thanks.
