Lian Li Launches RB Series Power Supplies Featuring Built-in Cable Grooves and Velcro Straps for Advanced Cable Management
Lian Li, one of the most recognized names in PC case and cooling design, has announced the launch of its new RB Series power supplies, a product line that redefines PSU design with the introduction of an integrated cable management system. This marks one of the first times a manufacturer has implemented cable management directly into a power supply unit, combining functionality, innovation, and user convenience into a single design.
The RB Series introduces built-in grooves and Velcro straps designed to keep excess or unused cables organized and out of the way, ensuring a neater build and improved airflow within the PC case. As demonstrated in the official product images, the Velcro straps are positioned along three sides of the unit, allowing builders to secure leftover or unconnected cables directly to the PSU. The unused cables can then be tucked into the specially designed grooves, preventing tangling and reducing interference when routing other essential cables.
While the concept itself is refreshingly new for the PSU market, Lian Li has applied it in a practical and affordable way, targeting the budget-friendly segment without sacrificing compatibility or safety. The RB Series models are ATX 3.1 and PCIe Gen 5.1 compliant, offering full support for the latest PC hardware platforms and next-generation GPUs. Each unit includes a dedicated 12V-2x6 PCIe connector, capable of up to 450W of power delivery, ideal for powering mid-range GPUs such as the NVIDIA GeForce RTX 5070 or RTX 5070 Ti.
In terms of design, the RB Series is semi-modular, with primary power cables for the motherboard and CPU permanently attached for stability, while peripheral and GPU cables can be connected as required. These PSUs are 80 Plus Bronze certified, capable of achieving up to 85% efficiency under typical system loads, ensuring consistent performance and energy savings.
Lian Li has equipped the RB Series with a 135mm Fluid Dynamic Bearing (FDB) fan, which offers quiet operation, improved cooling efficiency, and longer lifespan. The PSU also incorporates multiple safety mechanisms, including Over Power Protection (OPP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), Over Current Protection (OCP), Under Voltage Protection (UVP), and Over Temperature Protection (OTP). These safeguards ensure the system remains protected under heavy or unstable load conditions, maintaining long-term reliability.
The Lian Li RB Series is available in three wattage variants, giving users flexibility depending on their build requirements:
Lian Li RB 550W – USD $49
Lian Li RB 650W – USD $59
Lian Li RB 750W – USD $69
Each unit includes a 5-year warranty, underscoring the company’s confidence in product quality and durability.
Availability spans across major online retailers, including Amazon, Newegg, Caseking, and Overclockers UK. Lian Li continues to demonstrate its design philosophy centered around user experience and system cleanliness by applying the same ingenuity seen in its popular case lineup to its new power supply solutions.
By merging affordability, technical compliance, and practical innovation, the RB Series not only simplifies cable management but also establishes a new design direction for future PSU development. The addition of integrated grooves and Velcro straps shows a clear understanding of modern PC-building aesthetics and the growing demand for easier, more efficient cable organization.
