Power Delivery for Modern Builds

The Lian Li RB 550W is a non-modular ATX 3.1 power supply rated for 550 W continuous output. It carries 80 PLUS Bronze certification with up to 85% efficiency and active PFC above 0.95. A single +12 V rail and DC-to-DC topology provide stable voltage regulation for gaming or creator systems.

Suited for Standard ATX Systems

Builders who want native PCIe 5.1 12+4 pin support and integrated cable routing channels with Velcro straps will benefit. Buyers who need fully modular cabling or higher wattage for multi-GPU configurations should look elsewhere.

ATX 3.1 and PCIe 5.1 Ready

The unit meets the Intel ATX 3.1 specification and includes a native 12+4 pin connector for modern graphics cards. A 135 mm hydraulic-bearing fan handles cooling, while protections cover OPP, OVP, SCP, OCP, UVP and OTP.

Frågor om den här produkten

Will the 20+4 pin and 4+4 pin EPS cables reach the motherboard headers in an older ATX case?

The fixed 20+4 pin cable is 600 mm long and each 4+4 pin EPS cable is 650 mm, so they reach standard ATX motherboard positions in most older cases.

How can I verify the fan is running quietly after installation?

The 135 mm hydraulic-bearing fan spins at low speed under typical loads; listen for a gentle airflow sound and check that the fan blade is turning through the rear grille.

Which cables come attached and what extra connectors must I purchase?

The unit ships with a fixed 20+4 pin main cable, two 4+4 pin EPS cables, one 6+2 pin PCIe cable, and a combined SATA/peripheral cable; no modular cables are included and no separate cables are required for a standard build.
