500 W ATX Power Supply

The KHACHIMO ST-500PFL is a 500 W ATX switching power supply built for standard desktop computers. It delivers the rated wattage through a conventional ATX form factor and arrives tested and confirmed working. The unit targets system builders who need a straightforward replacement or a new-build power source without extra frills.

Suitable for basic office or home PCs

This supply fits builds that draw modest power from a single rail and do not require auxiliary GPU connectors beyond what a 500 W design typically provides. It is not for configurations demanding high continuous loads, multiple high-end graphics cards, or server-grade redundancy. Buyers who need modular cabling, higher efficiency certifications, or specialised form factors should look elsewhere.

500 W rated output

The decisive specification is the 500 W maximum output, which sets the ceiling for every component the unit can support. If the total system draw stays comfortably below that figure, the ST-500PFL will handle it; if the build requires more headroom, a higher-wattage model is necessary.

Questions about this item

Will the fan need replacement during the unit's lifespan?

The power supply uses a switching design with internal cooling; fan longevity depends on operating temperature and dust accumulation in the case.

Which protection triggers first when the 500W ATX supply runs at full load continuously?

Over-power protection activates if sustained draw exceeds the rated 500W, shutting the unit down before components overheat.

How much heat and noise does the ST-500PFL produce during all-day operation?

As a standard ATX switching supply, it exhausts warm air through the rear fan; noise level varies with load and case airflow.
