Power supply unit Lian Li RS1000G 1000 W ATX 20+4 pin, 80 PLUS Gold, White, 135 mm fan

The Lian Li RS1000G is a 1000 W ATX power supply in white, designed for modern PC builds requiring reliable, high-efficiency power delivery. It features a compact 150 × 86 × 150 mm form factor, a 135 mm cooling fan, and native ATX 3.1 12V-2×6 GPU connectors for next-generation graphics cards. The unit is 80 PLUS Gold certified and achieved Cybenetics Platinum-level efficiency in real-world testing, delivering stable performance across demanding workloads.

Advantages

The RS1000G combines industry-grade German EPCOS capacitors, a rotatable 90° AC inlet and dual installation options to provide flexibility, longevity and cleaner cable routing. Its dual-sided 20+4-pin motherboard output, braided-textured main cable with cable comb, and ultra-flexible flat cables with magnetic clips allow neater layouts for side-mounted or back-connect builds. The PSU includes an integrated RS Hub with USB Type-A and USB-to-USB cables and comes with a full set of modular cables for immediate installation. A 10-year warranty on the PSU and a 2-year warranty for the RS Hub back the product’s long-term reliability.

How to use

Install the RS1000G in your case using either the standard or side-mounted orientation and rotate the AC inlet if needed to match your cable routing. Connect the 20+4 pin motherboard cable (choose the convenient side for routing), attach required PCIe 12V-2×6 connectors to your GPU, and connect SATA/Molex peripherals using the supplied modular cables. Plug the RS Hub using the included USB cable if you want to route front-panel or internal USB devices through the PSU. Ensure all connections are secure before powering on the system.

Recommendations

For optimal thermal performance and minimal noise, place the PSU so its 135 mm fan has clear airflow and avoid obstructing vents. Use the magnetic clips on the flat cables to manage excess length and keep cable runs short in compact or side-mounted PSU configurations. Follow the 10-year warranty terms by using the provided cables and avoiding unauthorized modifications.
