Asus launches 3000W Pro WS Platinum PSU
Asus has just revealed the Pro WS Platinum power supply line, which was announced at Computex 2025. Available in whopping 3000-watt, 2200-watt, and 1600-watt variants, these heavy-duty PSUs are engineered to drive multiple high-end graphics cards.
The PSUs incorporate PCIe connectors with gold-plated copper pins. This design choice promises to reduce connector temperatures by up to 10°C compared to standard 12V-2×6 connectors and improve power delivery efficiency by increasing contact between internal socket pins.
For thermal management and durability, the units use dual-ball fan bearings, which are designed for longer lifespans than sleeve-bearing alternatives. Extruded aluminium heatsinks are also integrated to dissipate heat from internal components. The PSUs are housed in a 175 mm-long chassis, shorter than some other 1600W units available.
These power supplies are compliant with ATX 3.1 and PCIe 5.1 standards. The cables are flexible and etched, with distinct colours for CPU and PCIe power connectors to aid installation and cable routing. Moreover, the Pro WS Platinum series carries an 80 Plus Platinum certification, indicating high power efficiency. This efficiency is partly attributed to the use of Japanese server-grade capacitors. A protective coating on the PCB is present to guard against moisture, dust, and debris. The power supplies come with a 10-year warranty.
The 3000W model is rated to support up to four GeForce RTX 5090 graphics cards, the 2200W model can power up to four GeForce RTX 5080 cards, and the 1600W variant can run two GeForce RTX 5090 graphics cards.
KitGuru says: Regardless of your choice, a Pro WS Platinum PSU will provide plenty of power to feed your components.
