Corsair WS3000 Platinum 3000 Watt ATX 3.1 Fully Modular Workstation Smps

The Corsair WS3000 is a fully modular ATX 3.1 workstation power supply delivering 3000 watts of continuous power — headroom engineered specifically for multi-GPU rendering rigs, AI training nodes, and professional CAD or animation workstations that push component power budgets to their limits. At the heart of the WS3000 is its 80 PLUS Platinum certification, which targets up to 94% efficiency under typical loads. Higher efficiency means less energy is wasted as heat, which translates directly to lower ambient temperatures inside the chassis, quieter fan operation under moderate loads, and reduced electricity costs over extended workstation uptime. Cooling is handled by a 140 mm fan using a dual ball bearing design, chosen for longevity in continuously powered professional environments. Connectivity is a key differentiator. The WS3000 provides four native 12V-2x6 connectors, the current-generation high-current GPU connector specified under PCIe 5.1, enabling the unit to support up to four discrete graphics cards simultaneously without adapters. Additional connectors include eight PCIe 6+2 connectors, nine SATA connectors, six PATA connectors, two EPS connectors, and one ATX connector — a comprehensive harness for fully populated workstation and server-adjacent builds. The fully modular cable architecture means unused cables stay out of the chassis entirely, simplifying airflow management in large tower enclosures. The WS3000 carries a rated MTBF of 100,000 hours and is backed by a 10-year warranty, reflecting confidence in the unit's reliability for demanding, around-the-clock professional use cases.
