New PC Won't Boot To Bios, no picture.

[ANPeck]

I have bought some brand new parts, theres no incompatibility as far as im aware of, but it doesnt even boot, not even to bios, it doesnt show any indication of a picture, the graphics card I know works as I used it in another for a short time.

Parts are as follows:
Corsair VS450
AMD FX-6300
ASUS M5A78L-M/USB3 Motherboard
G.Skill Ripjaws X 2400mhz

Thanks in advance.
