hi i am wondering what would be better for this system does more power matter or could i have a bigger wattage than needed all the parts are on here http://uk.pcpartpicker.com/p/wVYc7P
Here are a few more options XFX TS Series 550W Bronze efficiency, non-modular ~ £50 XFX XTR Series 550WGold efficiency, fully modular ~ £70
I did XFX first since they use SeaSonic as their manufacturer - they tend to be solid units Antec High Current Gamer M 520W Bronze efficiency, Semi-modular ~£60 (another SeaSonic built unit)
About the least expensive PSU I would suggest (not really recommend) would be the EVGA 500W 80+ efficiency, non-modular this one is built by HEC ~£35 - review can be found here http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=384 (linked to conclusion page)
A few more options anyway
The wattage PCPartPicker shows is quite accurate but you'll want your PSU to provide about double that since PSU's are most efficient ~50% load so a 400W - 500W PSU would be ideal.
I'd recommend the Fractal Design Integra M 450W for £43 as a viable option - it's semi-modular so you shouldn't end up with a lot of cable clutter
