Engineered for ATX 3.1 and PCIe 5.1 Power
Built to the ATX 3.1 specification, this fully modular unit supplies 1200W of continuous power to handle transient spikes from flagship processors and GPUs. It features native PCIe 5.1 support, utilising a dedicated 12V-2x6 connector to deliver stable, high-wattage power directly to modern graphics cards without the need for multi-cable adapters.
Advanced Routing and Internal Connectivity
Lian Li addresses common clearance and routing challenges with a 90-degree rotatable AC inlet, allowing the power cord to be oriented for optimal case compatibility. The dual-sided 20+4 pin output further simplifies cable management by letting builders route the main ATX cable in the direction that best suits their chassis. To support complex cooling and RGB setups, the power supply includes the RS Hub, a 4-port internal USB expansion module that resolves motherboard header shortages in hardware-heavy systems.
Premium Components and Platinum-Level Efficiency
Internal power delivery is anchored by German EPCOS industrial-grade capacitors, ensuring long-term reliability and strict voltage control under heavy loads. While carrying an 80 PLUS Gold certification, the unit exceeds standard expectations by achieving a Cybenetics Platinum efficiency rating. This translates to less wasted energy drawn from the wall and lower internal heat generation during sustained gaming or rendering workloads.
Silent Operation Under Load
Cooling is handled by a 135mm Fluid Dynamic Bearing (FDB) fan capable of reaching 2400 RPM when required. A built-in fanless mode keeps the power supply completely silent during idle or low-load tasks. Even under demanding conditions, the unit maintains a Cybenetics Lambda A noise rating and a PPLP SSS acoustic certification, peaking at just 36.27 dBA measured at 30°C from 100cm away.
Comprehensive Protection and 10-Year Warranty
A complete suite of electrical protections, including Over Power, Over Voltage, Under Voltage, Short Circuit, Over Temperature, and Over Current safeguards, shields your components against power anomalies. The core power supply is backed by a 100,000-hour MTBF rating and a 10-year manufacturer warranty, while the included RS Hub is covered for two years.
