I wan't to get this: http://www.scan.co.uk/products/650w-psu-xfx-p1-650s-ukb9-85-eff-80-plus-bronze-sli-crossfire-eps-12v-quiet-fan-atx but I'm not sure if it will be enough for:

CPU: 4670k
GPU: Asus 7870
Cooler: 212 EVO
HDD: Caviar Blue 1TB 3.5" 7200RPM
Case: Z11 Plus
Optical drive: LG GH24NS95 DVD/CD Writer
RAM: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600
Motherboard: Z87-G43

that is a really good branded certified PSU (XFX650W)made by SEASONIC (one of the best OEM of all times), is more than enough to power your system

How much power do you think the PC would use? I will OC the GPU a little and I might OC the CPU to about 4GHz.

You can overclock both with that power supply , plenty of power to spare.

as SR-71 Blackbird just said, you have headroom enough to OC your PC with that PSU
