So, Im upgrading my PC and I now just need a good fully-modular PSU.

My basic specs are:

CPU: I7 5820k (Will be overclocking)
GPU: GTX 970 (Also overclocking, will be buying a second in the future for SLI)
RAM: 16GB DDR4

I live in the UK, I am not near a Microcenter and my budget is <£120. I need it to be modular as my build is aimed to be aesthetically pleasing, meaning I will also be swapping out the stock PSU cables included with whatever I get with some white/grey/black ones.

TL;DR: Need PSU for PC. Modular and <£120.
