## Long description

The Zalman ZM850-TMX Teramax 80 Plus Gold is an 850W ATX12V power supply unit with a fully modular design and 80 PLUS Gold efficiency. It supports an AC input range of 100–240V at 50–60 Hz and features flat cables, active PFC and a 120 mm fan to provide stable, efficient power for desktop systems while simplifying cable management.
Advantages
80 PLUS Gold certification ensures high conversion efficiency (up to 92% peak) across common load levels, reducing wasted power and heat. The fully modular architecture and flat cables improve airflow and cable routing while minimizing voltage drop and impedance. Advanced internal design limits voltage fluctuation to within 3% for stable output, and quality components with FDB-bearing fan technology increase durability and reliability.
Suitable for
High-performance gaming PCs and workstations requiring up to 850 W
Systems where neat cable management and improved airflow are important
Upgrades for older PSUs to gain higher efficiency and lower operating temperatures

How to use
Install the PSU into a compatible ATX case aligning the mounting holes, secure it with screws and connect only the modular cables required by your motherboard, GPU and drives. Verify the AC input rating on the unit matches your mains supply (100–240 V, 50–60 Hz). Route the flat cables to optimize airflow, then power on the system and monitor voltages and temperatures during initial use to confirm stable operation.
Usage recommendations
Use the fully modular cabling to keep airflow unobstructed; maintain ambient case ventilation and clean the fan periodically. For reliable long-term operation, avoid continuous loads near the maximum rating and ensure adequate case cooling when running high-power components.
