Hi all, iv been looking around on amazon for Christmas ideas and started flicking through pc stuff as I saw one thing, then another, then another lol! you know how it is! My pc does not need upgrading at the mo but when I sli I will have to get a stronger psu. I have seen on amazon for instance.... Corsair Builder Series CXM 750W Modular 80 PLUS Bronze Certified ATX/EPS PSU and that's for £68.98 then I see the likes of ACE 750W BR PSU with 12cm Red Fan and PFC - Black for £22.85.... wft?! I cant explain that price difference so can anyone else??! surely not just brand! Im still learning and catching up from 8 odd years ago when I moved to console!
