Workstation Power Supply: Insufficient supply capacity | Auckland
Pattern to record: Resets occur only during simultaneous CPU and graphics load.
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 the supply cannot sustain the combined transient demand of installed hardware.
Mains and connector safety
Proprietary workstation connectors must not be assumed to follow ATX wiring. Headline wattage alone does not prove transient performance.
Workshop checks
- Check event indicators, connector mapping and rail stability with the installed configuration documented.
- Calculate connector and rail requirements and compare a suitable known supply.
Repair and loaded verification
If the checks support this cause, install a correctly rated quality supply and required cables. 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.
