Zalman ZM1000-ARX power supply unit 1000 W 20+4 pin ATX Black

The Zalman ZM1000-ARX 1000 W power supply unit delivers stable, high-efficiency power for desktop PCs. Featuring an 80 PLUS Platinum efficiency rating and fully modular cabling, this PSU supports a wide AC input range (100–240 V, 50–60 Hz) and provides a single +12V DC rail for consistent voltage to system components. The unit includes a quiet 135 mm fan, high-quality Japanese 105°C capacitors, secondary protection circuitry and compact dimensions (150 × 180 × 86 mm) for straightforward integration into typical PC cases.

Advantages

The Zalman ZM1000-ARX uses high-quality made-in-Japan 105°C capacitors to maintain stability under high temperatures, frequencies and currents. An integrated Active PFC circuit improves power factor and overall efficiency, while the single +12V rail design ensures a stable voltage supply to critical components. Robust secondary protection ICs provide Over Current, Over Power, Over Voltage, Under Voltage, Over Temperature and Short-Circuit protection. The fully modular cable system helps organize cables for improved airflow inside the case.

How to use

Install the Zalman ZM1000-ARX into your PC case following standard PSU mounting procedures and connect the modular cables to the motherboard, CPU, GPU and storage devices as required. Ensure the AC mains cable is connected to an appropriate outlet within the specified 100–240 V range. Route and secure modular cables to maintain unobstructed airflow around the 135 mm fan. Power on the system and verify stable operation under expected loads.

Recommendations

For reliable long-term operation, position the unit to allow unobstructed airflow to the fan, use quality mains power and consider a surge protector or UPS. Periodically check and clean dust from the fan and ventilation areas. Ensure cable connections are secure and compatible with your components before powering on.
