Is it worth paying extra for a modular power supply when building a new PC?
Lian Li has launched the RBO750B power supply, an ATX 3.1 unit designed to provide stable power for modern PC builds. The device offers a total output of 750 watts while integrating next-generation connectivity standards.
Why it matters
By prioritizing internal stability and omitting full cable modularity, the design aims to simplify builds for users seeking reliable power for high-end components. It introduces native 12V-2x6 connectivity to the entry-level market, reflecting a shift in power delivery standards.
The unit provides 750 watts of power and features a Toshin Kogyo capacitor rated at 470uf and 420v. It utilizes a 135mm hydraulic bearing fan with a maximum noise output of 40 dB and includes integrated cable-routing loops.
The players
Lian Li
Lian Li is a Taiwan-based manufacturer known for designing and producing computer cases, power supplies, and specialized PC cooling solutions.
The details
The RBO750B utilizes a Helly Technology platform with DC-to-DC topology to ensure stable voltage regulation. Testing for the device included an AMD Ryzen 9 7950X CPU and an RTX 3090 GPU undergoing a 13-hour continuous burn-in at 17°C.
Timeline
September 24, 2026: The product launch was officially published.
The Tech Race
The integration of native 12V-2x6 cabling in a budget-conscious power supply represents a rapid industry-wide move to phase out legacy adapter cables. This positions Lian Li to capture demand from entry-level builders who require compatibility with current graphics card hardware.
Users can purchase the unit for an MSRP of $69.99, making it a cost-effective option for those building systems that require high-power 12V-2x6 connections. The non-modular design means builders will have fixed cabling, which impacts the interior space management of their PC cases.
The takeaway
The RBO750B highlights a clear trend toward bringing advanced power standards to lower price points without sacrificing essential component quality. Builders should account for the fixed cabling design when planning their interior cable management strategy.
