Asus' 3000 W ROG power supply is excessive for gaming rigs

To mark the ROG brand's 20th anniversary, Asus has unveiled the ROG Thor 3000W Titanium III Edition 20, a 3 kW power supply aimed at gaming PCs. Three-kilowatt units already exist for workstations—Corsair's WS3000 and Asus' own Pro WS 3000W Platinum are examples—but fitting one into a gaming rig stretches utility.

The Thor packs four 12V-2x6 power sockets despite the fact a gaming PC can only make practical use of a single RTX 5090; adding more cards for giggles won’t make games run faster. Asus includes gaming-oriented extras such as a magnetically attached OLED display and a voltage monitoring system to protect an RTX 5090, but it does not promote AI workloads or present the unit as a workstation product.

Its 3000 W limit (1600 W when using a 115 V supply) and peak efficiency around 1600 W sit far above what any gaming setup is likely to need. The device reads more like an over-the-top statement than a bespoke gaming PSU.
