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.
