Hi, Right I've come to the conclusion that my PSU isn't cutting it and I'm in need of buying a new one, now I'm not an expert on buying PSUs I've got a general idea of what's alright and what's not but I don't know the finer details, that's why I've come to you. The Experts. I know it's alot to ask and I have done my research already but could if you have the time could I get a few people to list their top 3 PSUs with teh following requirements

Must have 2 PCIe connectors (SLi certified basically)
must be a minimum of 700w
Good quality
Maximum price is £150
as many 4pins as possible.
UK price and UK websites only please.

I've decided that as everything else in my system is top of the line (almost) it's time I got the power supply top of the line as well

This is my list (in no order)

Thanks for your time.
 
Why must the power supply be a minimum of 700 watts?
It would help if you list the rest of your components and tell us what you will be doing with your system. Are you a hardcore gamer into serious overclocking and mutiple video cards?
