Overview
Powering high-density artificial intelligence workstations and multi-GPU compute rigs presents demanding electrical challenges that standard desktop hardware simply cannot address. Delivering 3000W of sustained continuous power, this unit tackles extreme workstation configurations by integrating four native 12V-2×6 connections alongside eight supplemental PCIe 8-pin leads. This connector density allows specialized workstations to distribute balanced, dedicated current across multiple high-draw accelerators simultaneously without relying on precarious splitters or third-party adapters.
Accommodating this level of continuous electrical throughput demands substantial physical infrastructure. Weighing 10.08 lbs (4.57 kg) with an enclosure depth of 7.87 in (200 mm), the chassis requires generous interior clearance found exclusively in large workstation towers and server-grade frames. Inside, high-grade power conversion stages achieve 80 PLUS Platinum efficiency, minimizing wasted energy and mitigating internal heat accumulation during continuous operational cycles protected by a complete suite of over-current, over-voltage, and thermal fail-safes.
Thermal management prioritizes hardware preservation over near-silent operation, utilizing a heavy-duty 5.51 in (140 mm) double ball bearing fan with a 12-pole motor that ramps from 400 RPM up to 3000 RPM under maximum workload. While this airflow strategy guarantees stable 24/7 continuous operation under punishing power draws, the acoustic footprint is decidedly tailored for machine rooms and dedicated studio workspaces rather than quiet office settings. Prospective integrators must also verify regional infrastructure, as standard 13A UK wall outlets limit sustained capacity to 2600W, requiring dedicated higher-amperage circuits to realize the unit’s full 3000W potential.
