Fuente de alimentación Zalman ZM1200-ARX 1200 W 20+4 pin ATX ATX negro

The Zalman ZM1200-ARX 1200 W power supply unit is a high-performance ATX PSU designed for demanding desktop systems. It delivers a continuous 1200 W total power with a single +12V rail and uses high-quality Japanese 105°C capacitors for stability at high temperatures, frequencies and currents. The unit is 80 PLUS Platinum certified and includes active Power Factor Correction (PFC) to improve efficiency and reduce input current distortion. A 135 mm ultra-quiet fan and modular DC cables support effective cooling and tidy cable management.

Advantages

The PSU combines a high-efficiency 80 PLUS Platinum rating with a 94% efficiency figure to reduce energy losses. Active PFC and a robust DC-DC design provide stable output under load. High-quality Japanese capacitors and a secondary protection IC ensure reliability by guarding against over-current, over-power, over-voltage, under-voltage, over-temperature and short-circuit conditions. Modular cables improve airflow inside the PC case, while the smart-controlled 135 mm fan balances thermal management and low noise.

Suitable for

• High-end gaming PCs
• Workstations for video editing or 3D rendering
• Overclocked systems and multi-GPU configurations
• Systems requiring a stable single +12V rail and high continuous power

How to use

Install the Zalman ZM1200-ARX into a compatible ATX case following the motherboard and case manufacturer guidelines. Connect the 20+4 pin ATX connector to the motherboard and attach required PCIe, CPU and SATA/Peripheral cables from the modular outputs to your components. Ensure the PSU input voltage switch (if present) matches your mains supply and secure the unit with the supplied screws. After installation, power on the system and verify stable operation and fan behavior under different loads.

Recommendations

For reliable long-term operation, use the PSU in a case with good airflow, keep ventilation openings clear of dust, and ensure the unit is not operated beyond its rated continuous 1200 W load. Periodically check cable connections and clean the fan and filters as part of regular maintenance.
