Lian Li RB 750W is made with high-quality electrolytic capacitors that guarantee stable and consistent performance even at 40°C. Thanks to this, the power supply has an 80 PLUS Bronze rating, which ensures high efficiency during everyday and gaming use.

Semi-modular design
The power supply has permanently connected 24-pin ATX and CPU-EPS cables and offers PCIe 6+2 and 12V-2x6 connectors (including a PCIe adapter).
The 12V-2x6 connector has a color-coded safety marking to prevent incorrect connection — if you see blue, the connector is not fully inserted.
SATA and peripheral cables can be connected via modular ports, so the interior of the system always remains organized and well ventilated.

Clean cable management
Integrated Velcro straps on three sides allow for easy bundling of excess cables, improving airflow and aesthetics in the computer case.

ATX 3.1 and PCIe 5.1 – future-proof standards
The Lian Li RB Series 750W complies with the latest ATX 3.1 and PCIe 5.1 standards, ensuring modern energy efficiency, security and stability requirements. An ideal choice for modern gaming PCs and next-generation hardware.

- Quiet and efficient cooling
- 135 mm HDB fan instead of the previous 120 mm
- Better airflow at lower rpm
- Noise level: 40.1 dB(A) at 1,600 RPM
- Stable temperature even under heavy load

The larger fan cools more efficiently while operating at a lower noise level, so the power supply remains quiet and reliably cool even under high load.
