The Lian Li SX1000P is a fully modular, 1000W power supply that natively supports ATX 3.1 and PCIe 5.1 standards to safely drive the latest generation of high-end graphics cards.
Native ATX 3.1 and PCIe 5.1 Support
Modern GPUs demand stable, high-capacity power delivery with strict transient response requirements. By adhering to the ATX 3.1 specification, the SX1000P handles extreme power excursions without tripping system protections, ensuring consistent performance during heavy gaming or rendering workloads. It includes a native PCIe 12+4-pin (12V-2x6) connector, allowing you to power high-end graphics cards directly without relying on bulky, multi-cable adapters.
Platinum Efficiency and Premium Components
Operating with both 80 PLUS Platinum and PPLP Platinum efficiency ratings, this 1000W unit converts more incoming AC power into usable DC power. This high efficiency generates less internal heat and reduces electrical waste compared to lower-rated models. The internal layout relies exclusively on 100% Japanese 105°C capacitors, ensuring stable voltage regulation, minimal ripple, and long-term reliability even under sustained heavy workloads.
Silent Operation Under Partial Load
Cooling is managed by a 120 mm Fluid Dynamic Bearing (FDB) fan capable of spinning up to 2000 RPM when maximum thermal dissipation is required. For everyday desktop use and light gaming, the PSU features a Zero RPM mode. The fan remains completely stationary up to a 40% system load, eliminating power supply noise during idle or low-intensity tasks.
Fully Modular Design in a Compact Footprint
Despite its robust 1000W capacity, the SX1000P maintains a highly compact 140 mm depth. This shorter footprint provides excellent compatibility with a wide range of ATX chassis and leaves ample clearance for cable routing. The fully modular design and all-white finish allow builders to connect only the specific cables their system requires, maintaining a clean aesthetic and ensuring unobstructed chassis airflow.
