Description
The LIAN LI RS1200G represents a significant leap in power delivery for enthusiast-grade hardware. Built on the ATX 3.1 standard, this 1200W unit is engineered to handle the massive power excursions of next-generation GPUs while maintaining Cybenetics Platinum-level efficiency. Its standout feature is a 90-degree rotatable AC inlet, allowing for seamless cable routing regardless of whether the PSU is mounted horizontally or vertically in modern chassis designs.
This product is for:
- Extreme Overclockers: Provides stable 1200W output with high-current copper alloy terminals for maximum power draw during peak loads.
- Creative Professionals: Ensures reliable power for multi-GPU rendering setups using German EPCOS industrial-grade capacitors.
- Custom Loop Builders: The compact 150mm depth leaves more room for pumps and reservoirs in mid-tower cases.
- Silent PC Enthusiasts: Features a 135mm Fluid Dynamic Bearing (FDB) fan with a zero-RPM mode for silent low-load operation.
- Aesthetic Builders: Available in both black and white finishes with fully modular cables to match any specific build theme.
Detailed specifications:
- Form Factor: ATX 12V v3.1
- Dimensions: 150mm (D) x 150mm (W) x 86mm (H)
- Efficiency: 80 PLUS Gold / Cybenetics Platinum / PPLP Gold
- Cooling: 135mm FDB Fan (2400 RPM max)
- Protection: OCP, OVP, OTP, OPP, SCP, UVP, NLP, SIP
- Connectors: Native 12V-2x6 (PCIe 5.1), Dual 20+4 Pin ATX
Installing the RS1200G is simplified by the dual 20+4 pin ATX output, which streamlines the thickest cable in the system for better management. The use of high-quality SECC material for the casing provides a premium feel, while the 10-year warranty offers long-term peace of mind. During high-load gaming sessions, the 135mm fan maintains a steady thermal profile without the aggressive noise ramp-up common in smaller units, achieving a Cybenetics A- noise rating.
Unlike traditional ATX 3.0 power supplies, the RS1200G utilizes the updated 12V-2x6 connector, which offers more secure mating and better thermal performance than the original 12VHPWR design. While many 1200W units exceed 170mm in length, LIAN LI maintains a 150mm footprint, making it compatible with a wider range of compact chassis without sacrificing the 135mm fan size or cooling efficiency.
Q&A:
- Does this PSU support the latest NVIDIA RTX 40-series cards? Yes, it includes a native 12V-2x6 cable designed for high-power PCIe 5.1 components.
- What is the benefit of the rotatable AC inlet? It allows the power cord to exit the case cleanly in both standard and vertical PSU mounting positions.
- Is the fan loud under load? No, it is rated at Cybenetics A- for noise, utilizing a Fluid Dynamic Bearing for quiet operation.
- What kind of capacitors are used? It features German EPCOS industrial-grade capacitors for superior heat resistance and longevity.
- How long is the manufacturer warranty? LIAN LI provides a comprehensive 10-year warranty for the RS series.
