Experience premium power delivery with the Lian Li SX Platinum 1000W, a fully modular ATX 3.1 compliant power supply engineered for high-performance builds. Certified with 80 PLUS Platinum efficiency, this unit delivers up to 92% efficiency at 50% load, ensuring cooler operation, quieter acoustics, and lower energy costs. The intelligent fanless cooling system operates silently at loads up to 40%, automatically engaging the 120mm FDB fan only when needed for optimal thermal management.
Built with premium Japanese capacitors (Rubycon, Nippon Chemi-Con, or Nichicon 105C-rated), the SX Platinum provides exceptional voltage regulation, minimal ripple, and long-term reliability even under demanding conditions. The compact 140mm form factor fits seamlessly into most PC cases while leaving ample internal space. Fully modular cabling with individually sleeved braided cables and cable combs ensures clean cable management and professional aesthetics. Native support for ATX 3.1 and PCIe 5.1 standards includes dual 12V-2x6 connectors for next-generation GPUs, complemented by six 6+2 pin PCIe connectors for maximum compatibility.
Comprehensive protection circuitry (OCP, OVP, OTP, OPP, SCP, UVP, NLP, SIP) safeguards your system against overcurrent, overvoltage, overtemperature, and short-circuit conditions. Backed by a 10-year limited warranty, this power supply combines cutting-edge efficiency with proven reliability for discerning enthusiasts and professionals.
