Hi all...
I am using an old PSU for my old-server...Model is TK-920TX by Task International Inc....Detailed specs you can find here ...
A description of what happened :
I recently bought a Bidirectional SATA-to-PATA & PATA-to-SATA adapter to test...It is a small board powered by a 4-pin floppy connector...with the device came a 4-pin floppy to 4-pin ata molex converter...
I connected the device using this converter, powered by the above mentioned PSU...after powering on and before getting into Windows, the cables of the converter were set on fire, so i immediately unpluged the power supply cable of the PSU to protect the machine from further damage...
After that, the server could not power-on, so i replaced the PSU with another one and all worked fine...
I powered on the "faulty" psu to examine it and tested the voltage of the rails with my DMM...everything seemed fine except the 12V & the -12V rails, which measured approx. ~10.7V...
I opened the PSU for internal visual examination but i could not locate any component to have failed/burnt...
Here are some photos :






If anyone can give a hint and cotribute in troubleshooting , welcome...
If photos of specific areas are needed, i can upload more...
Thank you in advance for your help
