Hi there, i was wondering what size psu i would need for this build;
Nvidia 770
AMD FX8320
4GB Ram
asus m5a97 R2.0
WD 1TB Blue

Thanks in advance

Nothing lower than 500W since those FX chips run hot. An Antec would be a good start, maybe from their HCG series. Modular to have less unused cables in the case.

If you intend on a second graphics card, the 650W would be absolute minimum, and 750W would be better.

230W for the GTX770 no matter what
50W for mobo/HDD/etc (estimate)
95W for 6300 versus 125W for 8320, not a huge difference

230+50+125 is 405W, plus 20% due to inefficiency is 485W
230+50+95 is 375W, plus 20% puts you at 450W

As you can see, not a real benefit / savings. If you have a 500W Platinum then you might be just fine, but really for the same or better price, a 550W Gold or 600W Bronze would be safer.

If you have any remote thoughts of overclocking, add another 10% to 20% to the above.

=========

Edit: to clarify. That 20% extra for inefficiency is the PSU inefficiency. An 80 Bronze needs that 20% buffer so those results are really pushing it if you do use a 500W Bronze. Could run fine for a bit, but I'd anticipate shutdowns when you run games hard on the 8320 chip.
