ASRock Steel Legend SL-1200P power supply review: Combines genuine Platinum efficiency with a winning stand-out design
The ASRock Steel Legend SL-1200P is a visually distinct, technically capable 1200W unit with genuine Platinum efficiency, dual 12V-2x6 outputs, and a few thoughtful engineering touches that set it apart.
In 2002, ASRock emerged from its parent company Asus as a manufacturer of budget-focused motherboards. After two decades of growth, the company expanded into graphics cards, monitors, mini PCs, and industrial systems. Power supplies had been absent from their product line until recently, when ASRock unveiled a suite of 20 power supplies across four series - Taichi, Phantom Gaming, Steel Legend, and Challenger.
The Steel Legend line resides between the company's cost-effective entry-level offerings and high-end premium models. The base Gold-certified units cater to mainstream users, while the Platinum-capable Steel Legend SL-1200P offers enhanced efficiency and power capacity, along with engineering upgrades justifying its premium price.
The SL-1200P specifications include a maximum output of 1200W, AC input ranging from 100 to 240VAC at 50-60 Hz, and an MSRP of $180. The unit comes boxed in a robust cardboard package with a protective pouch for the PSU, a comprehensive accessory bundle, and a concise installation guide. The cables feature distinctive grey sleeving with black connectors, a feature not commonly seen in other manufacturers' offerings.
One standout feature is the temperature sensor embedded within the 12V-2x6 cables, which automatically shuts down the unit if overheating occurs. The fan is a high-capacity Globe RL4Z S1352512EH-3M rated at 2300 RPM, and the PSU's design is credited to Taiwanese manufacturer HEC, known for refining top-tier designs.
