The MAG series fights alongside gamers in pursuit of honor.

With added military-inspired elements in these gaming products, they were reborn as the symbol of sturdiness and durability.

ATX 3.1 READY

The gaming power supply can hold up to 2x total power excursion and 3x GPU power excursion, remaining stable when paired with high performing graphics cards.

80 PLUS GOLD CERTIFIED

The efficiency of your power supply directly influences your system's performance and your power consumption. The 80 PLUS Gold certification promises lower energy consumption and higher efficiency.

ONLY WHAT YOU NEED

The connectors that required by the build need to be used, significantly reducing cable clutter and simplifying the system's overall build. Additionally, the included cable pack provides a storage solution for any unused cables.

ALL THE MORE ORGANIZED

Organizing cables is often the most bothersome part of building a PC. The flat cables make cable management easier and less of headache! Thanks to the flat cables, the entire system can be more organized and has more room for unobstructed airflow.

FLUID DYNAMIC BEARING

The power supply's fan comes with a fluid dynamic bearing that perfectly balances cooling performance and noise level.

FULL BRIDGE LLC + SR + DC/DC

A full-bridge LLC with DC/DC converter combined to achieve higher conversion efficiency, stable output voltage, and quick voltage adjustment for different usage scenarios, thus providing a stable power supply design
