Fonte de alimentação Lian Li RS1200G 1200 W 20+4 pin ATX 80 PLUS Gold preto

The Lian Li RS1200G is a 1200 W ATX power supply designed for desktop PCs. It supports 100–240 V AC input at 50/60 Hz and features a 20+4 pin ATX motherboard connector. The PSU is built in a compact 150 × 86 × 150 mm chassis with a 135 mm cooling fan and delivers efficient power with an 80 PLUS Gold certification and Cybenetics Platinum-level real-world efficiency.

Advantages

The RS1200G offers dual installation options and a 90° rotatable AC inlet for flexible mounting and cleaner cable routing in standard or vertical PSU orientations. Its dual-sided 20+4 pin output and ultra-flexible flat cables with magnetic clips simplify cable management, while braided-textured main cable and an included cable comb improve build appearance. Industrial-grade German EPCOS capacitors and a reinforced dual-color 12V-2×6 GPU cable provide stable, long-term performance. An integrated RS Hub supplies additional USB connectivity directly from the PSU, and a protective dust cover is provided for the 18+10 pin output. The unit ships with a full set of modular cables and includes a 10-year warranty for the PSU and a 2-year warranty for the RS Hub.

Suitable for

• High-performance gaming PCs and workstations requiring up to 1200 W power
• Compact or dual-chamber case builds where space and cable routing are constrained
• Systems using next-generation GPUs that require 12V-2×6 power connectors

How to use

Install the RS1200G into your case in the preferred orientation using either the standard or side-mount option. Rotate the AC inlet if needed to match the case layout and route the 20+4 pin motherboard cable from the side that provides the cleanest path. Connect the dual-color 12V-2×6 cables to compatible GPU power ports and secure modular cables as required. Use the RS Hub to route USB connections from the PSU rather than the motherboard when desired. Reconfirm all connections before powering on and ensure the PSU fan intake is unobstructed for proper cooling.

Recommendations

For optimal stability and cable management, plan cable routing before installation, use the provided magnetic clips to shorten excess flat cables, and choose the AC inlet orientation that minimizes bends in power cords. Verify GPU connector compatibility with the RS1200G native 12V-2×6 terminals and keep ventilation paths clear to maintain low noise and temperatures.
