The ASRock Steel Legend SL-1200G is a 1200W ATX power supply for PC builders equipping a high performance desktop with current graphics hardware. Its ATX 3.1 design and PCIe 5.1 readiness suit gaming systems and demanding workstation builds.

Gold efficiency certification is paired with Cybenetics Platinum and Lambda A certification. The fully modular cable design helps keep a build tidy, while the native 12V-2x6 connector has a dual-colour design with green connector sections to make it easier to check that the plug is seated correctly. The 135mm fluid dynamic bearing fan uses iCOOL control: with the mode enabled, it can remain off at low to medium loads and activate as load or temperature rises.
