ASUS Announces Pro WS Platinum Series Power Supplies, up to 3000 W

ASUS today announced the Pro WS Platinum series of power supplies, available in 3000-, 2200- and 1600-watt variants. These heavy-duty PSUs are built to power multiple GeForce RTX 5090 or NVIDIA RTX PRO 6000 graphics cards. Each unit features PCIe connectors upgraded with gold-plated copper pins for cooler operation as well as increased durability and improved power-delivery efficiency. These PSUs also feature dual-ball fan bearings and extruded aluminium heatsinks for long-lasting performance—all in a compact design. Plus, a 10-year warranty offers peace of mind over the long term.

Surprisingly compact but ready for the most powerful workstations
Whether a workstation handles hefty 3D rendering or next-gen AI workloads, these PSUs will deliver the power needed to thrive. The three variants of the ASUS Pro WS Platinum series each provide a different power ceiling, so users can select the one that best suits their needs. The 3000 W model is built to provide rock-solid, stable power delivery for up to four GeForce RTX 5090 graphics cards. The 2200 W model can power up to four GeForce RTX 5080 cards. The 1600 W model provides enough power to support up to two GeForce RTX 5090 graphics cards.

Each of these high-wattage PSUs are quite compact at only 175 mm long, making them a bit shorter than even some 1600 W models on the market. Their relatively small footprint makes them suited for a wide range of PC cases, while also making cable management easier and improving airflow.

Designed for a streamlined build process
ASUS Pro WS Platinum series PSUs offer an easy installation experience and efficient, long-lasting performance. Thanks to ATX 3.1 and PCIe 5.1 compatibility, these PSUs are ready for the latest hardware. The pliable etched cables deserve some special attention. Distinctly colored CPU and PCIe power connectors and high flexibility enable effortless component installation and cable routing.

Premium power, exceptional efficiency
With ASUS Pro WS Platinum series PSUs, users do not have to choose between high-end wattage or efficiency. Despite being built to deliver an astounding flow of power to high-performance workstation components, these PSUs are remarkably efficient, as their 80 Plus Platinum certification confirms. Exceptional efficiency is achieved in part due to Japanese server-grade capacitors.

Built to go the distance
The design of ASUS Pro WS Platinum series PSUs places a focus on safety and durability. Each unit features PCIe connectors that offer a variety of benefits and enhanced resistance to the wear-and-tear of insertion and removal. Gold-plated copper pins lower connector temperatures by up to 10°C, versus standard 12V-2×6 connectors. Increased contact between the internal socket pins and connectors also reduces resistance, improving power-delivery efficiency.

To help ensure a long lifespan, the flexible etched cables are constructed of premium materials designed to keep operation at up to 50°C lower than the safety limit. Extruded aluminium heatsinks also cover critical components to keep temperatures and noise low, and dual-ball fan bearings are designed to last up to twice as long as traditional sleeve-bearing designs. Each model also features a protective PCB coating that guards the circuit board against moisture, dust and debris.

Upgrade any workstation with an ASUS Pro WS Platinum series PSU
For those who need a workstation motherboard ready to support multi-GPU ambitions unlocked by ASUS Pro WS Platinum power supplies, take a look at the ASUS Pro WS TRX50-SAGE WiFi A, which features three PCIe 5.0 x16 slots. Or step up to the ASUS Pro WS WRX90E-SAGE SE, which boasts seven PCIe 5.0 x16 slots. Either choice stands ready to seize the power of the new AMD Threadripper 9000 series CPUs as well.
