The Lian Li RS1200G is an ATX 3.1 power supply unit providing a 1200W continuous power output for high-demand computing systems. It holds an 80 PLUS Gold certification, indicating high efficiency in converting AC to DC power. The internal design utilizes German EPCOS capacitors to support stable voltage regulation and long-term reliability. A native 12V-2x6 power connector is included for direct compatibility with modern graphics cards, and an integrated RS Hub expands connectivity for peripherals and cables.
This unit features a fully modular cabling system, allowing system builders to use only necessary cables for improved airflow and a cleaner internal layout. Cooling is managed by a 135 mm fan with a fluid dynamic bearing, which operates silently at low to medium loads due to its semi-passive functionality. Housed in a white enclosure, the PSU maintains a standard 150 mm depth to fit most ATX cases. A rotatable AC inlet offers additional flexibility for installation in various chassis orientations.
