## Long description

Zalman TeramaxII SE 850 W is an ATX power supply unit designed for desktop PCs requiring stable and efficient power delivery. It provides 850 W total output, accepts 100–240 V AC at 50/60 Hz and meets 80 PLUS Gold efficiency standards. The unit includes a 120 mm FDB cooling fan, full-modular cabling with flat cables, and an 18+10 pin motherboard connector, and is compatible with Intel and AMD Ryzen platforms.
Advantages
The PSU features 80 PLUS Gold efficiency and Cybenetics ETA Gold certification for high energy conversion, minimizing heat and reducing operating costs. It is Intel ATX 3.1 compatible with support for PCIe 5.1 and a 16-pin connector for modern graphics cards. Active PFC with up to 99% power factor, DC-to-DC 12V conversion, and high-temperature rated capacitors ensure stable voltage under varying loads. Full-modular flat cables reduce resistance and improve airflow, while multiple protection circuits (OTP, OCP, OPP, OVP, UVP, SCP) and EMI filtering protect connected components.
Suitable for
Gaming desktops with modern GPUs (PCIe 5.1)
High-performance workstations using Intel or AMD Ryzen CPUs
Systems requiring efficient, quiet cooling and stable 12V output
Custom builds where cable management and airflow are important

How to use
Install the Zalman TeramaxII SE into a standard ATX case, secure it to the PSU mount, and connect the 18+10 pin motherboard connector. Attach required modular cables for CPU, GPU (use the 16-pin PCIe connector if applicable), SATA and peripheral devices. Ensure the input voltage selector (if present) and AC cable match your mains supply and switch on the system. The unit manages power delivery automatically and provides stable 12V output via its DC-to-DC converters.
Usage recommendations
Use only the necessary modular cables to maintain good airflow; keep ventilation openings and honeycomb vents unobstructed. For high-load systems, ensure adequate case cooling and verify that GPU peak power excursion requirements are within the PSU’s supported budget. Regularly check connections and dust filters to maintain cooling efficiency and long-term reliability.
