CORSAIR Unveils WS3000, a 3000W ATX 3.1-Compliant Power Supply for High-End Workstations
CORSAIR has announced the launch of its most powerful power supply to date, the WS3000, designed specifically for workstation-class builds that require extreme power delivery for multi-GPU configurations and compute-heavy workloads such as AI training, machine learning, and advanced content creation.
Delivering a staggering 3000 watts of output, the WS3000 is capable of powering up to four flagship GPUs such as NVIDIA’s upcoming GeForce RTX 5090. The unit is ATX 3.1 compliant and ships with four native 12V-2x6 connectors, ensuring compatibility with next-generation graphics cards. Additionally, it provides 4x traditional 8-pin PCIe connectors, which can be split into 8x 8-pin connectors via the bundled PCIe cables, offering flexibility for varied setups.
The PSU utilizes a single +12V rail design that can deliver up to 250A of current, simplifying load distribution across demanding components. While this configuration maximizes available power for high-draw scenarios, it also raises the potential for thermal buildup, a challenge CORSAIR addresses with a heavy emphasis on industrial-grade components and active cooling solutions.
Unlike CORSAIR’s enthusiast gaming PSUs, which often prioritize low-noise operation, the WS3000 is engineered with reliability and thermal stability as the primary focus. The PSU features a 140mm double ball-bearing fan that operates continuously, without a Zero RPM mode. While this results in higher acoustic levels under load, it ensures consistent airflow and safeguards against overheating in dense, multi-GPU environments.
Despite its unprecedented capacity, the WS3000 is relatively compact, measuring 175mm (L) x 150mm (W) x 86mm (H). This makes it practical for workstation cases where space efficiency is crucial, especially when paired with multiple GPUs and high-core count CPUs.
A key limitation of the WS3000 is its reliance on 220–240V AC power input. The PSU will not function natively with 110/120V outlets, which are standard in regions such as North America. Users in those markets will require either a step-up converter or infrastructure capable of supporting dual-voltage input.
The CORSAIR WS3000 is priced at $599 USD and comes backed by a 10-year warranty, reflecting the company’s confidence in the PSU’s build quality and long-term reliability.
While CORSAIR is best known among PC enthusiasts and gamers, the WS3000 firmly targets enterprise users and workstation professionals who demand uncompromising stability for AI development, 3D rendering, or simulation workloads. Its design prioritizes resilience and raw output over silence, making it a specialized solution for the most power-hungry configurations.
Do you think 3000W PSUs like the CORSAIR WS3000 will become essential for future high-end PCs, or will most users remain well within the 1000–1600W range?
