What power supply do I need

[Backtothere]

My build: http://uk.pcpartpicker.com/user/Backtothere/saved/39nR

I'm adding liquid cooling later when I can afford a basic one

If you plan on overclocking, get a better board.

Anyway, for single graphics card get a quality 550w unit like the XFX Core.

For dual graphics look at 650/750W.

With any of theese PSU's you can overclock all your system.

My full suggestion for a single card system that is capable of decent overclocking if you add some cooling.
Also added some faster RAM at the same price.

What about the Gigabyte GA-Z87X-D3H, what do you mean by "Better" motherboard
I'm using single graphics

For overclocking you want higher quality boards for more stability.
When it comes to Gigabyte I don't suggest anything under the "UD" designated boards like the UD3/UD4/UD5.

What board would you suggest then that doesn't cost a truck load
And when you say 550w is that considering the overclocking and a mid power watercooler

 

[Novuake]

550w includes that, yes.

The board I originally suggested.

This is also decent actually for a little less.
