  1. fist of all stop being such a huge ******, second of all you can get more than 4 gb for ~£10 more, third choose a better PSU, fourth your HDD is overpriced, fifth uATX? really?
  2. This topic has been moved from the section CPU & Components to section Systems by Mousemonkey
  3. firstly dont use fowl language. It makes you look unintelligent and ill-tempered and yeah it is my first time in building a computer-please respect that fact. secondly i dont need 8GB and when i do ill buy it. Thirdly, i dont need any more than 450W, fourth, i meant 500GB, fifth, ive changed it to an atx now
  4. 450W will not run your system well.
    Straight from the AMD page:
    450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended

    You are cutting it super close. It is best to have a 100W leeway on the PSU. I recommend a 550W PSU from Corsair, Antec, or XFX.
