The Lian Li SX1000P delivers 1000W of 80 PLUS Platinum certified power in a compact 140mm ATX chassis, fully supporting the latest ATX 3.1 and PCIe 5.1 standards for modern hardware. This fully modular unit is engineered to provide stable, efficient power delivery for high-end graphics cards and multi-core processors.
Built for Modern Power Demands
The SX1000P is designed to handle the transient power spikes of current-generation flagship GPUs. It adheres to the ATX 3.1 and PCIe 5.1 specifications, ensuring reliable power delivery to high-draw components. The unit supplies up to 1000W of total continuous power, with a robust single +12V rail capable of delivering 999.6W. This ensures your processor and graphics card receive clean, uninterrupted power even under maximum system load.
| Max DC Output | 1000 W |
| Combined +12V Output | 999.6 W |
| Combined +3.3V & +5V Output | 100 W |
| Input Voltage | 100 - 240 Vac |
Platinum Efficiency and Premium Components
Operating with an 80 PLUS Platinum efficiency rating, this power supply minimises heat generation and reduces electrical waste. The internal design utilises 100% Japanese 105°C capacitors, which maintain tight voltage regulation and long-term reliability under heavy thermal loads. An Active Power Factor Correction (PFC) design achieves a power factor greater than 0.95 at full load, further optimising energy draw from the wall.
Silent Operation Under 400W
Cooling is handled by a 120mm Fluid Dynamic Bearing (FDB) fan, chosen for its low acoustic profile and extended lifespan. The SX1000P features a fanless mode that keeps the fan completely stationary up to a 40% system load. This means the power supply operates silently when drawing 400W or less, ideal for desktop work, media consumption, or light gaming.
Compact 140mm Footprint and Fully Modular Cabling
Despite its 1000W capacity, the SX1000P is housed in a compact chassis measuring 150 x 86 x 140 mm. The 140mm depth provides maximum clearance for cable routing in mid-tower and compact ATX cases. The fully modular design allows you to connect only the cables your system requires, reducing case clutter and improving internal airflow.
