Zalman ZM500-LXII power supply unit 500 W 20+4 pin ATX ATX Black

The Zalman ZM500-LXII 500 W power supply unit provides stable power for desktop PCs with an active PFC system and a maximum power factor of 99%. Designed for 200–240 V AC input at 50–60 Hz, the unit includes a 20+4 pin ATX motherboard connector, a 50 cm motherboard cable and a 450 mm SATA power cable, plus a 120 mm cooling fan to manage heat. With 500 W total power, 85% efficiency and an MTBF of 100,000 hours, the PSU is a practical choice for everyday system builds and upgrades.

Advantages

The active PFC circuit improves power factor up to 99% for consistent voltage delivery and reduced mains distortion. An 85% efficiency rating reduces wasted energy and lowers internal heat generation, while the 120 mm fan and active cooling help maintain component temperatures. The included standard connectors and 500 W capacity suit a range of mid‑tier desktop configurations, and the stated MTBF of 100,000 hours indicates long service life under normal operating conditions.

Suitable for

• Home and office desktop PCs
• System upgrades where a 500 W PSU is required
• Builds using ATX motherboards with 20+4 pin connectors

How to use

Install the Zalman ZM500-LXII into a compatible ATX case, secure it with the supplied screws and connect the 20+4 pin ATX connector to the motherboard. Attach SATA power cables to storage devices as needed and connect any additional peripheral connectors your system requires. Ensure the AC input voltage matches the 200–240 V rating and that the case airflow is not obstructed to maintain effective cooling.

Recommendations

For reliable operation, use the PSU within its rated 500 W capacity, keep intake and exhaust vents clear, and maintain ambient temperature within typical computer room conditions. Regularly check cables and connectors for secure seating; avoid prolonged operation near the unit's maximum load to extend service life.
