## Long description

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
