Zalman ZM1200-TMX TerraMax 80 PLUS GOLD PSU 1200W/Full-modular 99.9% Active PFC/Single power supply unit

The Zalman ZM1200-TMX Teramax 1200W is a fully modular ATX12V power supply with 80 PLUS Gold certification, offering high conversion efficiency and a compact form factor. It supports a wide AC input range (100–240V, 50–60 Hz) and delivers a rated output of 1200 W while using flat cables for simpler cable management; the design aims to reduce voltage fluctuation and heat generation for stable system operation.

Advantages

Certified 80 PLUS Gold efficiency reduces energy loss and heat generation, with up to 92% peak conversion efficiency under optimal conditions. The fully modular layout and flat cables minimize cable clutter and improve airflow. Internal design and component selection limit voltage fluctuation to within about 3% for stable power delivery, and high-quality components provide durable, reliable performance.

Suitable for

• High-performance gaming PCs
• Workstations and content-creation rigs
• Systems requiring many add-on cards or drives
• Builds where cable management and airflow are important

How to use

Install the Zalman ZM1200-TMX into a compatible ATX power supply bay following your chassis manual. Connect only the modular cables required by your motherboard, CPU, GPU and drives to reduce clutter and maintain airflow. Verify AC input voltage compatibility (100–240 V) before powering on. Ensure the 120 mm fan is unobstructed and that airflow paths in the case are clear for effective cooling.

Recommendations

For best results, use the fully modular cables provided and route flat cables along case edges to optimise airflow. Keep the PSU clean of dust and provide adequate case ventilation; match the unit’s 1200 W capacity to your system’s peak load with an allowance for future upgrades.
