Product information

Description

The Lian Li RB0750B.B is a 750 W ATX power supply designed for desktop PCs. It comes in a classic black finish and follows the ATX 3.1 standard to support modern components and high transient loads. The unit includes a 24‑pin ATX motherboard connector, modular peripheral/SATA cables, and a native 12V-2×6 PCIe arrangement for improved GPU power delivery. Built-in cable routing channels and Velcro straps on three sides of the housing simplify cable management, helping create a cleaner internal layout and better airflow.

Advantages

The RB0750B.B combines compact dimensions with robust electrical design: a 150 mm depth allows wide case compatibility while premium 105°C capacitors, a single high-amperage +12V rail and DC-to-DC architecture provide stable voltage under load. A 135 mm HYB temperature-controlled fan offers effective cooling at lower speeds, reducing noise. The PSU is 80 PLUS Bronze certified (around 85% efficiency) and includes six protection mechanisms (OVP, UVP, OCP, OPP, OTP, SCP) plus multiple international safety certifications.

Подходит для

Сборок формата ATX в стандартных и компактных корпусах
Систем с одной или несколькими мощными видеокартами (поддержка до трёх 8‑контактных PCIe у версии 750 W)
Офисных и домашних компьютеров, где важна энергоэффективность и низкий уровень шума
Сборок, требующих аккуратной укладки кабелей и улучшенного воздушного потока

How to use

Install the PSU into a compatible ATX case using the standard mounting points, observing the 150 mm depth requirement. Connect the 24‑pin ATX main cable to the motherboard, attach the 4+4 CPU power connector and any required PCIe GPU cables. Use the modular SATA/peripheral cables only for devices you intend to power; route cables through the built-in grooved channel and secure them with the PSU’s Velcro straps to maintain clear airflow. Ensure correct connector orientation and tighten all connections before powering on the system.

Usage recommendations

For optimal performance and longevity, keep the PSU operating environment below 40°C, avoid obstructing the intake/exhaust areas, and connect only necessary modular cables. Regularly inspect cable routing and dust accumulation around the 135 mm fan. Use the 750 W model when planning multi‑GPU or high‑power CPU configurations to ensure adequate headroom.
