Lian Li’s new R8 PSUs debut with integrated cable management

Lian Li's power supply line-up expands this week with the new R8 550W, 650W and 750W models. All three are fully compliant with the new ATX 3.1 standard, so you can be sure that this PSU will be suitable both now and well into the future.

The RB Series features an integrated cable management system with a built-in groove and Velcro straps to secure excess cables, paired with a semi-modular layout that lets users connect SATA and peripheral cables only when needed. The 650W and 750W units also include a native PCIe Gen 5.1 12V-2×6 connector (up to 450W) for next-gen GPU support.

With a high amperage single +12V rail and a DC-to-DC conversion design for enhanced voltage stability and power quality, the RB Series is engineered for reliable performance. Cooling is handled by a quiet 135mm FDB fan, ensuring efficient airflow while keeping noise levels in check. Operating at just 33.2 dBA to 40.1 dBA, depending on the model, the fan delivers quiet performance even under full load. Other built-in protections include OPP, OVP, SCP, OCP, UVP, and OTP.

The Lian Li R8 550W PSU will be available for around $49.99, going up to $59.99 for the 640W model and $69.99 for the 750W model.
