Which PSU should I get?

[Raphalation]

I'm looking to buy a PSU of around 600w for my budget gaming build (below) I'm unsure what to really look for having very little knowledge of power supplies.
Here is a list of the PSU's I was looking at. http://uk.pcpartpicker.com/parts/power-supply/#sort=a8&w=700,600,500&p=1,2&qq=1
I wouldn't fancy spending more than around £70 as i am on quite a tight budget
I also plan on overclocking the fx 6300 sometime in the future which I know needs more power. I also don't think I will be using multiple graphics cards.
Thanks for any help!

This is my core build I plan on making:

the XFX P1-650S-NLB9 isn't modular does that matter?

 

[siddharthmukul007]

yes that is the one

zalman z11 has good internal space and great cable management, doesn't matter much.

last question, is the one you suggested the same as XFX P1-650X-XXB9, except that it isn't modular? In which case I would go with the XFX P1-650X-XXB9 which is basically the same price

 

[siddharthmukul007]

seasonic itself is the oem of xfx....so basically you get the same psu. only brand, service and price differs

 

[Raphalation]

Ah ok that makes sense. I looked up the XFX P1-650S-NLB9 and the XFX P1-650X-XXB9 and they seemed pretty much the same so i'll go with the XFX P1-650X-XXB9 because its modular. Thanks for the help!
