Workstation Power Supply: Incorrect modular PSU cable | Auckland
Pattern to record: The system fails immediately after a cable change or a drive is damaged.
Identify the supply and load
A workstation may have proprietary power connectors, multiple processors or high-current expansion cards. Record the installed configuration and OEM supply specification rather than assuming an ordinary ATX replacement is suitable. One possible explanation is that a cable from another supply presents the wrong pin arrangement.
Mains and connector safety
Proprietary workstation connectors must not be assumed to follow ATX wiring. Modular cables are not universally interchangeable even when connectors fit.
Workshop checks
- Check event indicators, connector mapping and rail stability with the installed configuration documented.
- Disconnect power and verify continuity against the exact PSU documentation.
Repair and loaded verification
If the checks support this cause, use only the cable set specified for that supply and assess connected parts. Verification should cover cold start, CPU and GPU load, storage activity, restart and extended work.
For an assessment of your professional workstation, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
