    Power supply problems relate mainly to video graphics. I suggest you get a quality power supply from the list of power supplies on this forum you can find with a search. Certainly 400 or 500 watts is a good choice, if it has steady output.

    google "PSU calculator", add 30% to the results, then buy quality.

    You're probably better off hand picking (or having a trustworthy person) hand pick you an aftermarket PSU. The ones that come with cases are rarely of a decent quality.

    Can you post your current motherboard model?
