Power and topology

The Lian Li RS1200G.BH is a fully modular ATX 3.1 power supply rated for 1200 W. It meets 80 Plus Gold, Cybenetics Platinum and PPLP Gold efficiency standards with active PFC above .90 at 115 V input.

Builds that benefit and those that will not

This unit suits high-end desktop systems that need PCIe 5.1 and 12V-2×6 600 W GPU power with clean cable routing via the rotatable AC inlet and dual-sided 24-pin output. Builders who do not require 1200 W or the new connector standard should look at smaller, less complex units.

Capacity headroom

The 1200 W rating comfortably handles multi-GPU configurations and overclocked CPUs while the 135 mm FDB fan runs in a fanless mode at low load. Headroom diminishes only when sustained draw approaches the maximum rated output.
