## Long description

Zalman Decamax 500 W is a standard ATX power supply unit delivering a guaranteed 500 W rated output for desktop PCs. It supports 200–240 V AC input at 50/60 Hz and carries 80 PLUS 230V EU certification for improved energy efficiency. The unit uses a single +12V rail design, an active PFC system with up to 99% power factor, and a 120 mm HDB cooling fan. Dimensions are 140 x 150 x 86 mm and the PSU complies with safety and environmental standards including KC, CE, CB, RCM, EAC and RoHS.
Advantages
The Decamax 500 W offers stable voltage delivery through a high-performance 105°C capacitor, active PFC with a high power factor, and a switching transformer to minimize input overload. Built-in EMI filtering and dual aluminum heatsinks reduce electrical noise and internal temperature. A 120 mm Hydro-Dynamic Bearing (HDB) fan provides low-noise, long-life cooling. Multiple protection circuits (OPP, OVP, UVP, SCP) protect the system, while ErP Lot 6 compliance ensures very low standby consumption (\<0.5 W).
Suitable for
Mainstream desktop PCs requiring up to 500 W continuous power
Systems using a single +12V rail configuration (CPU and GPU stability)
Builds prioritizing quiet operation and long fan lifespan
Environments needing standard ATX form-factor compatibility (140 x 150 x 86 mm)

How to use
Install the Zalman Decamax 500 W into a compatible PC case using standard ATX mounting points. Connect the main 24-pin ATX and the required CPU and peripheral power connectors to the motherboard, CPU, GPU and drives. Ensure the AC mains voltage matches the unit specification (200–240 V). Route the supplied flat sleeve cables to improve airflow and cable management. Power on the system and verify stable operation and expected fan behavior under load.
Usage recommendations
For reliable operation, keep the PSU intake and exhaust clear of dust and obstructions, allow adequate case airflow, and periodically check connections. Use this unit in systems whose combined power draw does not exceed the rated 500 W and avoid overloading to preserve longevity and ensure protection circuits function as intended.
