ok here it is... My old PSU died, had it for 2 years so didnt really mind. Bought a new Q-Tech 350 'silent' PSU from RefreshComputers and well...its not so silent. Ive noticed at times it has a ring to it and sometimes a different noise. Ive had no power problems or nething so im not totally bothered, but thought i better had ask. Good news / Bad news?
