27-3V07 PSU
Preliminary Information
Leak Risk Medium
Batteries None
Mounting Technology Through Hole
Capacitor Types Aluminum Electrolytic, Ceramic
Destructive Entry No

This power supply is from a generic portable PC chassis that had branding from a computer shop but no visible manufacturer information. The system had a late SMD style AMD 386 motherboard installed in it.

Known Issues

Sparking Sound and Fish Smell

  • Leaking cap(possibly from C8) fluid boiling from shorted traces
  • Leak from capacitor mounted above caused a short on two traces on the bottom causing charring and audible sounds

    Leak from capacitor mounted above caused a short on two traces on the bottom causing charring and audible sounds

Solutions

  • Clean & recap

Disassembly Notes

PSU is attached with ISA style card edge connector
