I am doing another build and I can't decide what power supply to use in it I am trying to keep my build to £600 so the psu budget is about £70.
I was thinking about getting the evga 750w b2 but I wasn't sure.
Also if you're wondering why I'm going so overkill with my power supply it's because I'm gonna be overclocking my i5 when I put an after market cpu cooler on it
