300W ATX power supply for desktop builds

This TDK-Lambda SWS300A unit delivers 300W through a standard ATX form factor. It is intended for system integrators and hobbyists assembling or repairing desktop computers that require a conventional power supply. The unit has been tested and confirmed working. It suits builds where a straightforward ATX supply is specified.

Tested working condition reduces integration risk

Each unit is verified operational before shipment, so builders avoid the uncertainty of untested surplus stock. The confirmed function means one less variable during system bring-up or troubleshooting. No additional cables, mounting hardware or software are mentioned in the supplier data. Buyers needing modular cabling or higher wattage should look elsewhere.

Questions about this item

Will the internal fan in the SWS300A need periodic cleaning or replacement?

The unit uses a switching design with forced-air cooling; dust buildup on the fan intake should be cleared with compressed air every six to twelve months to maintain airflow.

What limit appears first when the SWS300A runs continuously at full load?

The 300 W rated output is the primary ceiling; sustained operation at that level will hit the thermal protection threshold before any voltage-regulation limit is reached.
