Incredible Efficiency for Minimal Cooling
Built using premium components, including Japanese 105°C capacitors, the Lian Li SX Series 850W PSU boasts incredible energy efficiency.

Thanks to their efficiency, an SX Series PSU is easy to maintain at optimum temperatures. When under a heavy load, the 120mm fan will spin at speeds of up to 2000RPM, delivering plenty of fresh air to keep the power supply cool. There is also a Zero RPM mode, where the fan stops spinning should the total load on the PSU drop to under 40%.
Modular Design for Clean Builds
With a modular design, the Lian Li SX Series Power is perfect for building a gaming PC with a clean aesthetic. Thanks to the modular backplate, you need only plug in the cables you require, keeping clutter to a minimum. Furthermore, the Lian Li SX Series Power comes with a full set of braided cables. These wires are much more pliable, making them easier to route through your case. This includes the custom 12V-2x6 cable, which features an in-house moulded 12+4 connector that utilises a dual-colour design, to indicate when the cable is fully seated.

In fact, Lian Li is so confident in the durability of these power supplies that they offer an incredible 10-year warranty with each SX Series PSU.
