Lian Li RB 750W Power Supply – Stable Performance
High-quality electrolytic capacitors ensure consistent and stable performance – even at temperatures up to 40 °C. As a result, the Lian Li RB Series Power Supply achieves high efficiency and carries the 80 PLUS Bronze certification.
Modern semi-modular power supply
Lian Li RB 750W Semi-Modular Design
The 24-pin ATX and CPU-EPS cables are permanently attached. In addition, the PSU provides PCIe 6+2 and 12V-2×6 connectors as well as an adapter for PCIe. The 12V-2×6 connector is color-coded to prevent incorrect installation – if you can see blue, it’s not fully plugged in.
SATA and peripheral cables can be connected as needed via modular ports, keeping your case neat and organized.
Clean cable management
Lian Li RB 750W Cable Management
The PSU includes Velcro straps on three sides to help you bundle excess cables easily. This reduces clutter and improves airflow within your PC case.
ATX 3.1 and PCIe 5.1 – Future-Proof Standards
The Lian Li RB Series 750W meets both the ATX 3.1 and PCIe 5.1 standards, providing modern specifications for efficiency, safety, and stability – ideal for current and next-generation hardware.
– Quiet & Efficient Cooling
– 135mm HDB fan instead of 120mm
– Better cooling at lower fan speeds
– 40.1 dB(A) at 1,600 RPM
– Stable temperatures even under heavy load
The larger fan improves airflow while operating more quietly. Even under high load, the power supply remains pleasantly quiet and reliably cool.
