Power high-end graphics hardware and performance-focused PC builds with 1,200 W output, ATX 3.1 compliance, and a native 12V-2x6 connector. ROG-THOR-1200P3-GAMING-E pairs its high-output platform with GaN MOSFET technology, which supports efficient power conversion in a demanding gaming system. Its Platinum designation identifies this model within the ROG Thor III power-supply range. GPU-First voltage sensing monitors power at the graphics-card connection rather than relying only on the power supply output. ASUS couples that capability with an intelligent stabilizer to help maintain stable GPU power under changing loads. The included ROG Equalizer 12V-2x6 PCIe power cable is engineered to reduce heat stress at the cable and connector, addressing a critical connection point in systems using high-power graphics cards. Turbo Mode increases cooling behavior for overclocking and sustained workloads. The signature OLED display provides local power-status visibility, while its magnetic attachment allows placement on either side of the unit for fan-up or fan-down installations. This combination suits builders who need substantial GPU power capacity, direct 12V-2x6 connectivity, and a display that remains visible after installation orientation is selected.
