Tired of stuffing extra PSU cables behind your motherboard tray? Lian Li’s new RB series power supplies bring cable management right to the source, with built-in grooves and Velcro straps that tame excess wiring before it clutters your case. It’s a simple idea with big impact: keep unused leads neatly secured, improve airflow, and make your build look cleaner with less effort.
The RB lineup integrates an “on-PSU” cable tidy system. Three sides of the housing include Velcro straps to bundle leftovers, while dedicated grooves let you tuck unused runs out of the way. That makes routing the cables you do need faster and less frustrating, especially in compact or budget cases where space is tight.
Despite the wallet-friendly positioning, the RB series is built for modern hardware. You get full ATX 3.1 and PCIe Gen 5.1 compliance, plus a native 12V-2×6 connector. On this lineup, the 12V-2×6 is rated up to 450W, which suits mainstream, power-efficient GPUs—think mid-range graphics cards like the RTX 5070 or RTX 5070 Ti class—without venturing into ultra-high-end territory.
The RB units are semi-modular, so essential leads are permanently attached while peripheral cables connect only as needed, reducing clutter right out of the box. Efficiency is certified 80 Plus Bronze, delivering up to 85% efficiency at typical loads. Cooling is handled by a quiet 135 mm fluid dynamic bearing fan, and the usual suite of protections is included: OPP, OVP, SCP, OCP, UVP, and OTP for added peace of mind.
