  1. It really depends on the quality and efficiency of your psu. what brand and model do you have? A really cheap one could burn out and destroy your whole computer.

    It will work but you are taking a slight risk of burning out the PSU which could destroy other components of your PC at the same time.

    Thanks for the info, would you recommend a decent PSU i should go with?If not, I will probably go with a reliable brand.
  5. I don't know what country you live in or what your budget is but you should go with a Corsair 430 watt or greater. Corsair makes some of the best and most reliable PSU's.
