CORSAIR WS3000 3000W 80+ Platinum ATX 3.1 Fully Modular Power Supply

The Corsair WS3000 is a 3000-watt ATX-form-factor power supply built for high-demand workstation and multi-GPU computing environments. Carrying an 80 PLUS Platinum certification, it delivers up to 94% efficiency under typical loads, which translates to reduced heat output, lower ambient noise from the 140 mm dual-ball-bearing fan, and measurably less wasted energy compared to lower-efficiency units. Compliance with the ATX 3.1 standard and PCIe 5.1 readiness means the WS3000 is designed to handle the transient power excursions demanded by the latest generation of discrete graphics cards without triggering over-current protection trips. Four native 12V-2x6 connectors make it straightforward to populate a multi-GPU workstation without adapters or daisy-chaining, directly benefiting users running large-scale animation rendering, CAD modelling, or AI and machine-learning training pipelines. A fully modular cable system lets builders route only the cables they need, improving airflow and simplifying assembly in large tower or full-tower enclosures. Eight PCIe 6+2-pin connectors, nine SATA connectors, six PATA connectors, two EPS CPU connectors, and one ATX motherboard connector provide broad compatibility across demanding platform configurations. The dual-ball-bearing fan is rated to spin continuously without zero-RPM mode, prioritising consistent thermal management under sustained full-load workstation operation rather than silent idle behaviour. Corsair rates the WS3000 for a mean time between failures of 100,000 hours and backs the unit with a 10-year warranty, underscoring the intended longevity in professional-use environments.
