Product information

Description

The MAG series power supply blends military-inspired design with durable construction to support gaming systems. This 850 W ATX unit is 80 PLUS Gold certified and ATX 3.1 ready, delivering efficient and stable power for modern CPUs and GPUs while featuring a single +12V rail and DC-to-DC topology for reliable voltage regulation.

Advantages

High efficiency reduces energy consumption and heat thanks to the 80 PLUS Gold certification. ATX 3.1 readiness and a native PCIe 5.1 connector ensure compatibility with current high-end graphics cards and permit power excursions for demanding GPU loads. Dual 4+4-pin CPU connectors supply ample 12V power for modern processors, while DC-to-DC design and a 105°C main capacitor improve voltage stability and long-term reliability. Certified copper-alloy connectors and multiple protection mechanisms enhance safety during high-current events. The fan curve is optimized for low noise under typical loads, and flat black cables simplify cable management.

  • Input: 100 - 240 V, 47 - 63 Hz
  • Topology: Full bridge with DC-to-DC modules
  • +12V design: Single +12V rail

  • Cables: Certified copper-alloy terminals, flat black cables
  • Compatibility: Supports NVIDIA GeForce RTX 40 Series

How to use

Install the power supply into an ATX-compatible case following the motherboard and chassis manual. Connect the 20+4 pin ATX motherboard connector, the dual 4+4-pin CPU power connectors to the processor power header, and the PCIe 5.1 connector(s) to compatible graphics cards as required. Ensure all connectors are fully seated and routed to avoid airflow obstruction. Verify input voltage selection is appropriate for your region (unit supports 100–240 V auto range). Power on the system and monitor initial operation for stability and normal fan behavior.

Recommendations

Use this PSU with systems that demand stable 12V delivery such as those with high-performance CPUs and NVIDIA GeForce RTX 40 Series GPUs. Keep the PSU and system in a well-ventilated case, periodically check cable connections, and avoid prolonged operation at maximum load to extend component life.
