Ive gone thro 3 power supplies in less than 2 years. 2 of them were Ultra's(not the greatest), and the latest 1 to die is a server class Antec Truepower. I have a surge protecter, but its a no-name Staples that I picked up on sale for $20. My question is: is there a problem with the circut in my room, or is my power bar working? Should I buy an APC? Thanks.
