ASUS ROG Thor 1600W Titanium III Platinum PSU GaN MOSFET GPU-First Stabilizer 10-Year

1600W Titanium III power supply

The ASUS ROG Thor 1600W Titanium III is a new ATX 3.1 power supply built for high-end gaming rigs and workstations that demand clean, high-wattage delivery. GaN MOSFETs raise efficiency by up to 30 percent over standard designs, while a patented GPU-First stabilizer improves voltage delivery to the graphics card by up to 45 percent. A magnetic OLED panel shows real-time power draw and can be mounted on either side of the unit. Dual ball-bearing fans and an all-aluminium enclosure keep thermals under control.

ATX 3.1 interface limits

ATX 3.1 compliance guarantees the voltage and current regulation required by modern GPUs and CPUs, but the standard itself does not mandate a specific efficiency tier beyond the 80 PLUS Platinum rating this unit carries. The 1600 W ceiling is the practical limit for sustained output; extended excursions above that level rely on Turbo Mode and component headroom rather than the base specification. Builders planning multi-GPU arrays or extreme overclocking should verify that their total system draw stays within the rated maximum.

Capacity and headroom

At 1600 W the unit comfortably powers flagship graphics cards and high-core-count processors with room for transient spikes handled by Turbo Mode. The Platinum-rated efficiency curve keeps waste heat low across typical loads, while the fully modular, etched cables simplify routing in spacious cases. Systems that require more than 1600 W of continuous power, or that lack clearance for the aluminium enclosure and side-mounted OLED, will need a higher-capacity or physically smaller design.
