ASUS ROG Strix 1200W Platinum — a high-end power supply with high efficiency

For users looking for maximum stability and performance for their demanding builds, the ASUS ROG Strix 1200W Platinum is the ideal solution. This power supply offers 1200 W on a single +12 V rail, ensuring enough power for even high-end components. Thanks to GaN MOSFET technology, it is more efficient and allows for cooler operation, while GPU-FIRST voltage stabilization improves graphics card power stability by up to ~45% during peak loads. With 80 PLUS Platinum certification and Cybenetics Lambda A acoustic certification, it provides high efficiency and quiet operation. In addition, this power supply is fully future-ready with support for ATX 3.1 and PCIe 5.1 with a native 12V-2x6 connector.

Maximum stability and efficient cooling

ROG Strix 1200W Platinum is designed to maintain high stability even during energy-intensive operations. GPU-FIRST Intelligent Voltage Stabilization via IVS cable provides better stability for graphics cards, which is crucial for gamers and graphics professionals. ROG heatsinks dissipate heat more efficiently, which extends the lifespan of the power supply, and the double ball bearing and 0 dB technology fan ensures quiet operation at low loads.

Modular cabling and compact design

Fully modular cabling allows users to customize the wiring exactly to their needs, which increases clarity and reduces clutter in the build. With compact dimensions of 160 × 150 × 86 mm, the power supply is suitable for smaller cases without limiting performance. A wide range of connectors is available, including 1× PCIe 16-pin (12V-2x6) for new graphics cards, 4× PCIe 6+2-pin and 6× SATA for drives and other peripherals.
