This review examines the RS1200G ATX 3.1 PSU, representing Lian Li's most sophisticated approach to power supply design. Would this cutting-edge design earn it a spot in our list of best power supplies? The RS1200G introduces a rotatable AC power receptacle, a world-first innovation that fundamentally rethinks PSU orientation and cable management. This mechanism allows the modular cable connectors to exit from either the rear or left side of the chassis, adapting to different case architectures. The implementation appears more versatile than competing solutions, though it introduces its own compatibility requirements. Complementing this mechanical innovation is an optional magnetic USB hub that can mount directly to the PSU, expanding connectivity options for modern systems.

In the Box
The Lian Li RS1200G ATX 3.1 PSU arrives in a sizable cardboard box with a predominantly black theme and blue accents. The unit itself dominates the front side, establishing immediate visual recognition. Protection is substantial, with the PSU enclosed in a protective pouch and surrounded by dense foam packaging inserts designed to withstand shipping stresses.
The bundle is comprehensive, exceeding typical PSU inclusions. Beyond the standard AC power cable and mounting hardware, Lian Li provides a magnetic USB hub capable of mounting anywhere within the chassis or directly on the PSU. Two USB cables accompany the hub, offering users a choice between internal motherboard header connection or rear panel USB routing. A specialized backplate with a cable routing notch enables clean exits when necessary. Magnetic cable organizers are included to replace traditional zip ties, offering repositionable cable management. Cable combs arrive pre-attached to select cables, with additional units included for user customization. Finally, Lian Li includes some basic cable ties as well.
