Lian Li SX1200P Black (G9P.SX1200P.B000.EU)

The Lian Li SX1200P Black (G9P.SX1200P.B000.EU) is a fully modular 1200-watt power supply designed for high-performance gaming and workstation systems where high efficiency, modern power standards, and broad case compatibility are essential. The unit complies with ATX 3.1 and PCIe 5.1, carries 80 PLUS Platinum and PPLP Platinum certifications, and delivers up to 94% efficiency at 50% load. The Lian Li SX1200P Black maintains the standard ATX length of 140 mm, a practical advantage for cases where space for the power supply and cable management is limited. It uses 100% Japanese capacitors from Rubycon, Nippon Chemi-Con, or Nichicon with a 105 °C temperature rating, and cooling is provided by a 120-mm FDB fan with a fanless mode up to 40% load. This means the unit can operate silently under light workloads, switching to standard operation with smart stop/start logic under heavier demand. Modern graphics cards benefit from a native 12V-2x6 connector with reinforced copper-alloy contacts, plus sufficient PCIe 6+2 connectors for high-end GPU configurations. The Lian Li SX1200P Black is ideal for top-tier builds requiring 1200 watts, Platinum-class efficiency, full modularity, a compact depth for its class, and the capability to handle peak loads up to 200% of rated capacity under ATX 3.1.
