LIAN LI SX Platinum 1200W 80 PLUS Platinum ATX 3.1 Fully Modular Power Supply - Black

Need a power supply that handles high-end hardware while staying quiet and matching your black build? The LIAN LI SX Platinum 1200W is it. 80 PLUS Platinum certification with up to 94% efficiency means less heat and lower power bills. It is ready for next-gen graphics cards with ATX 3.1 and a 12V-2×6 connector, and handles power excursions up to 200% of rated output. At light loads the fan stops completely for silent operation. Braided cables with combs and 100% Japanese capacitors complete the package.
