## Long 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.
