Having problems with your Computer Utilities & Maintenance ?

I purchased a Sparkle SPI270LE power supply as a replacement for a 160W power supply in my HP Pavilion s3220n PC. On installation, the unit would not power up. All connections were hooked up correctly. I know of other people that have made this substition without problem. What could be wrong? Fred


Answers :

These power supplies can be tough to test without a bonifide genuine load tester made for these power supplies. Switching power supplies seem to need a load in order to operate. If you have everything plugged in including your hard drives and it still doesnt work then it is likely defective. I have a apparently good power supply that decided to do the same thing to me in a working machine. I swapped out the power supply and it worked again.
Sometimes new power supplies can be no good. Switching power supplies can be somewhat fragile. The newer the power supply the more fragile they seem these days.
