Lian Li RB 750W power supply, 80 Plus Bronze, ATX 3.1, PCIe 5.1, 135mm fan, non-modular, black

750W ATX 3.1 power supply for modern PCs

This 750W unit targets builders assembling gaming or creator systems that need ATX 3.1 compliance and a native 12+4pin connector. It delivers continuous rated output at 40°C ambient temperature with active PFC above 0.95 at 115Vac. The 80 PLUS Bronze rating confirms up to 85% efficiency under typical loads.

Non-modular design with built-in cable routing

All cables are fixed to the unit, including a 20+4pin main connector, two EPS 4+4pin cables, one PCIe 6+2pin, one 16pin to 6+2pin adapter and one 12+4pin cable rated for 450W. SATA and peripheral leads are also attached. Integrated routing channels and Velcro straps on the housing help secure excess length behind the motherboard tray for cleaner airflow.

Replaces older Bronze units lacking ATX 3.1

The jump is worthwhile when a build requires the 12+4pin interface for newer graphics cards or when the platform demands ATX 3.1 transient response. It also suits systems moving up from lower-wattage Bronze models that cannot sustain 750W continuously at 40°C. Builders who need fully modular cabling or higher efficiency ratings should look elsewhere.
