Product information

Description

The Lian Li RS1000G is a 1000 W ATX power supply designed for desktop PCs, combining compact dimensions (150 × 86 × 150 mm) with high efficiency and modular connectivity. It features 80 PLUS Gold certification and demonstrated Cybenetics Platinum-level efficiency in real-world testing. The unit includes a 135 mm fan, an innovative 90° rotatable AC inlet, dual-sided 20+4-pin output, and premium German EPCOS capacitors for stable long-term operation. The white finish and braided-texture main cable with cable comb support tidy, visually refined builds.

Advantages

The RS1000G delivers high efficiency and low noise across a wide load range, supported by Cybenetics Platinum-level performance and PPLP.info SSS noise ratings. Its compact ATX form factor with strong cooling performance makes it compatible with dual-chamber cases and side-mounted PSU layouts. Flexible cable options include an exclusive dual-colour 12V-2×6 GPU cable, ultra-flexible flat cables with magnetic clips for shortening, and a rotatable AC inlet plus dual-sided 20+4-pin routing to simplify installation and cable management. The PSU ships with a full set of modular cables, an RS Hub for additional USB connectivity, and carries a 10-year warranty (RS Hub: 2 years).

Suitable for

  • High-performance gaming and workstation builds requiring up to 1000 W
  • Compact ATX or dual-chamber case layouts with side-mounted PSU options
  • Custom builds where neat cable management and visual finish are important
  • Systems using next-generation GPUs requiring 12V-2×6 connectors

  • Total power: 1000 W
  • AC input voltage: 100–240 V, 50/60 Hz
  • Motherboard connector: 20+4 pin ATX
  • 80 PLUS certification: Gold (Cybenetics Platinum-level efficiency observed)
  • Fan: 135 mm, 0–1600 RPM
  • Form factor: ATX, dimensions 150 × 86 × 150 mm
  • Special features: 90° rotatable AC inlet, dual-sided 20+4-pin output, German EPCOS capacitors
  • Colour: White
  • Warranty: 10 years (PSU), 2 years (RS Hub)

How to use

Install the RS1000G following standard ATX PSU mounting procedures. Choose between standard or side installation and rotate the AC inlet up to 90° if required by the case orientation. Connect the 20+4-pin motherboard cable and required modular cables for GPU, CPU and peripherals; use the dual-sided 20+4 layout and braided main cable to route cables neatly. Attach the RS Hub using the supplied USB cables when additional internal USB connectivity is needed. Ensure correct seating of 12V-2×6 GPU connectors and secure all connections before powering on.

Usage recommendations

For best results, use the included modular cables and magnetic clips to shorten and secure excess cable length, keep the PSU ventilation area clear, and verify compatibility of your case layout with the rotatable inlet and side-mount options. Observe the 10-year warranty conditions and keep the RS Hub cable connections accessible for service or upgrades.
