Product details

The Lian Li SX Platinum power supply delivers efficient and reliable power for demanding computer systems. With an 80 Plus Platinum certification, it achieves up to 94 percent efficiency at typical loads, reducing heat generation and operating costs. The fully modular cable design allows for the connection of only the necessary cables, ensuring optimal airflow and tidy case cabling. High-quality Japanese capacitors ensure stable voltage regulation and increased lifespan during continuous operation. The quiet 135 mm Fluid Dynamic Bearing fan automatically adjusts its speed according to thermal load for optimal cooling with minimal noise. Comprehensive protection circuits safeguard against overvoltage, undervoltage, overcurrent, overload, short circuits, and overheating. The power supply supports modern graphics cards and processors with multiple PCIe and CPU power connectors and is compatible with ATX 12V v2.4 and EPS 12V standards. Its compact dimensions of 150 mm depth, 150 mm width, and 86 mm height allow for installation in most standard and small form factor cases. The robust steel housing with a matte black finish combines high build quality with an appealing design for system builders who value reliable performance.
