This article covers Lian Li RB650 80 Plus ブロンズ 非モジュラー.

Overview

The Lian Li RB650 (model RB0650B) is a 650W ATX 3.1 & PCIe 5.1 compliant power supply unit with 80PLUS Bronze certification. Despite its 650W rating, it features a native 12V-2x6 (12+4 pin) connector, enabling seamless compatibility with the latest GeForce RTX 40 series and upcoming GPUs. Its semi-modular design allows you to attach only the SATA and peripheral cables you need, reducing cable clutter and improving case airflow. This PSU targets mid-range to upper-mid-range gaming PCs and creator workstations. A 135mm low-noise hydraulic bearing fan spins up to 1600RPM under load while keeping noise at a modest 39.3dBA. An integrated cable management system built into the PSU housing helps tuck away excess cables for a cleaner build.

Compatibility Guide

Standard ATX form factor (150mm x 150mm x 86mm) fits most ATX and MicroATX cases. Connectors include: main 24-pin ATX, CPU EPS 4+4 pin, PCIe 12+4 pin (12V-2x6), SATA, and peripheral power. 650W capacity is well-suited for mid-range GPUs such as the RTX 4060 or RTX 4070. High-end GPUs (RTX 4080 and above) may exceed the recommended wattage. Semi-modular cabling: motherboard and CPU cables are fixed; SATA and peripheral cables are detachable.

Product Info

Released in 2025, the Lian Li RB650 sits in the entry-to-mid-range segment. Its 80PLUS Bronze certification (up to 85% efficiency) balances cost and reliability. The unit carries a standard 5-year manufacturer warranty. The standout feature at this price point is the native 12V-2x6 connector, which is rare among Bronze-rated PSUs.

Best Use Cases

First-time PC builders: The semi-modular design simplifies cable management, making it beginner-friendly. ATX 3.1 support future-proofs the build for next-gen GPUs. Mid-range gamers who value quiet operation: The 135mm fan runs at a quiet 39.3dBA under load and is even quieter at lower loads. Ideal pairing with RTX 4060 / 4070 class GPUs. Compact ATX case builds: At 150mm depth, it fits easily into most cases, and the integrated cable management keeps the interior tidy.

Things to Consider

650W is insufficient for high-end GPUs like the RTX 4080 Super or RX 7900 XT. For such builds, consider the 750W variant (RB0750B) from the same series. 80PLUS Bronze efficiency is lower than Gold or Platinum units. If you run heavy loads for extended periods or care about electricity costs, a higher-efficiency PSU may be worth the extra investment. Semi-modular design means the 24-pin and CPU EPS cables are permanently attached. If you prefer fully modular cabling, look elsewhere. * Competitors in the same price bracket include the Corsair CX650 and Thermaltake Smart BM3 650W. Compare the presence of a 12V-2x6 connector and warranty length before deciding.
