The Lian Li RB 650W power supply uses high-quality electrolytic capacitors to ensure stable and consistent power supply even at temperatures up to 40°C. The efficiency reaches 85% at half load, which is confirmed by the 80 PLUS Bronze certification.

Modern semi-modular design
The power supply comes with fixed 24-pin ATX and CPU-EPS cables, as well as modular PCIe 6+2 and 12V-2x6 connectors, which are also compatible with AMD, NVIDIA and Intel graphics cards.
The 12V-2x6 connector is color-coded 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 system always remains organized and well ventilated.

Clean cable management
With the help of integrated velcro straps on three sides, excess cables can be easily tied together, thus reducing clutter, improving air flow, and making the inside of the computer case cleaner.

ATX 3.1 and PCIe 5.1 – future-proof standards
The Lian Li RB Series 650W complies with ATX 3.1 and PCIe 5.1 standards, ensuring the latest energy efficiency, security and performance requirements are met — ideal for modern gaming PCs and next-generation hardware.

- Quiet and efficient cooling
- 135 mm HDB fan for optimal cooling
- High airflow at low rpm
- Noise level: 39.3 dB(A) at 1,600 RPM

The larger fan provides efficient cooling while remaining quiet — guaranteeing stable and cool operation even under heavy load, making it ideal for long gaming sessions.
