ASUS ROG Thor 1200W Platinum III PSU | ATX 3.1, Gaming, Platinum

Keep flagship CPUs and GPUs fed with clean, stable power under sustained load. ASUS ROG Thor 1200W Platinum III is built for high-draw systems that need more than basic wattage: it pairs 80 PLUS Platinum efficiency with ATX 3.1 support, a GaN MOSFET design, and GPU-First Intelligent Voltage Stabilizer to help maintain consistency when graphics demand spikes. The magnetic OLED display gives at-a-glance visibility into power draw, while Turbo Mode is designed for users who want maximum thermal and electrical headroom during heavy sessions. This is the kind of PSU chosen for premium builds where transient response, efficiency, and long-term reliability matter as much as raw output. For integrators and enthusiasts building around top-tier components, the Thor 1200W Platinum III offers the margin that cheaper units often lack. It is engineered to support modern high-performance platforms with the confidence expected from a flagship ASUS power supply, backed by a 10-year warranty.
