The Lian Li RS1200G Rotational Shift delivers 1200 W of ATX 3.1 power while solving complex cable management challenges through a 90-degree rotatable AC inlet and dual-sided 24-pin outputs.
Engineered for Cable Routing Flexibility
Traditional power supplies often force awkward cable bends in compact or dual-chamber cases. The RS1200G addresses this with a 90-degree rotatable AC inlet, allowing you to orient the power cord to best suit your chassis layout. Internally, the dual-sided 24-pin outputs let you route the thickest motherboard cable from whichever side offers the cleanest path. Combined with a fully modular design and a white SECC housing, this unit ensures your build remains uncluttered and visually cohesive.
ATX 3.1 and PCIe 5.1 Ready for High-Draw GPUs
Built to the ATX 3.1 specification, this 1200 W unit handles the severe transient power spikes characteristic of modern flagship graphics cards. It includes a native 12V-2x6 connector compliant with PCIe 5.1 standards, delivering power directly to compatible GPUs through a single, secure cable. For older or multi-GPU configurations, the unit provides extensive legacy support.
| Total Wattage | 1200 W |
| PCIe 5.1 Connectors | 1x 12V-2x6 |
| Standard PCIe Connectors | 5x PCIe 6+2-pin |
| EPS Connectors | 2 |
| SATA / Molex Connectors | 12 / 4 |
Cybenetics Platinum Efficiency and Silent Cooling
High wattage requires efficient conversion to minimise waste heat. The RS1200G holds both 80 PLUS Gold and Cybenetics Platinum efficiency certifications, alongside a PPLP Gold rating. Cooling is handled by a 135 mm Fluid Dynamic Bearing (FDB) fan that peaks at 2400 RPM. Under light loads, the fanless mode keeps the unit entirely silent. Even at full draw, acoustic output is capped at a highly manageable 36.27 dBA, keeping your system quiet during intensive gaming or rendering sessions.
Included RS Hub for Expanded Connectivity
Modern enthusiast builds often require more internal USB headers than standard motherboards provide, especially when integrating multiple RGB controllers, LCD screens, and smart fan hubs. To solve this, the RS1200G includes an RS Hub accessory in the box. This 4-port internal USB hub expands your motherboard connectivity, ensuring you have enough headers to support complex cooling and lighting ecosystems.
10-Year Reliability and Comprehensive Protection
Long-term reliability is critical for a high-wattage power supply. The RS1200G is rated for a 100,000-hour Mean Time Between Failures (MTBF) and operates safely in ambient temperatures up to 40 °C. It features an active PFC (>0.90) and a complete suite of electrical protections, including OCP, OVP, OTP, OPP, SCP, UVP, NLP, and SIP. Lian Li backs this unit with a 10-year warranty, providing peace of mind through multiple system upgrade cycles.
