500 W ATX power supply for basic desktops

This unit delivers 500 W of rated power for entry-level desktop builds that prioritise low energy consumption and low noise. It uses a manual 115 V / 230 V input switch and provides a 20+4 pin motherboard connector, dual 4-pin CPU power, four SATA connectors and a 6-pin to 6+2-pin graphics lead. The clearly marked cables simplify assembly for first-time builders. Efficiency exceeds 80 % under typical loads.

Thermal sensor fan control and 12 cm airflow

A 12 cm fan adjusts its speed automatically based on an internal thermal sensor, keeping acoustic output low during everyday tasks. The design targets basic desktop systems with modest heat output rather than high-performance rigs. Hold-up time is rated above 10 ms, giving the system a brief ride-through during momentary mains dips. Build quality uses durable materials for a long service life.

100 000 hour rated lifespan under sustained load

The power supply is rated for 100 000 hours of continuous operation, reflecting its intended use in always-on office or home PCs. Without active PFC, sustained heavy loads may draw more reactive current from the mains than units with active correction. The manual voltage selector must be set correctly before extended high-load sessions. Buyers who need active PFC or higher sustained efficiency should look elsewhere.

Questions about this item

How do I connect the 20+4 Pin motherboard and dual 4+4 Pin CPU cables during installation?

Align the keyed 20+4 Pin connector with the motherboard socket and press until the latch clicks, then plug both 4+4 Pin CPU plugs into the 8-pin EPS header; the clearly marked cables prevent reversed insertion.

Which part will need replacement first after long-term use?

The 12 cm thermal-controlled fan is the only moving component; after the rated 100000-hour lifespan its bearings may wear, requiring a fan swap to keep airflow.

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

The manual 115V/230V voltage switch and lack of active PFC mean input-current harmonics and efficiency above 80% become the practical ceiling before the 500W rating is reached.
