Fully modular ATX 3.1 power supply

This 1500 W unit delivers fully modular cabling so only the cables a build requires are installed. It is aimed at enthusiasts and workstation users who need reliable power for PCIe 5.1 graphics cards and high-end CPUs. The design follows the Intel ATX 3.1 standard and includes a 12V-2x6 cable for modern GPUs.

140 mm fluid dynamic bearing fan with Zero RPM mode

A single 140 mm fan uses fluid dynamic bearings for long life and quiet running. Zero RPM mode stops the fan completely at low to medium loads, keeping the system near-silent during everyday tasks. All capacitors are 105 °C rated Japanese electrolytics, and the fully modular layout simplifies cable routing inside any compatible case.

Cybenetics Platinum efficiency above 92 %

The supply meets 80 PLUS Platinum and Cybenetics Platinum targets, reaching over 92 % efficiency under typical loads. High efficiency reduces waste heat, which in turn lets the fan stay off longer and keeps noise to a minimum. iCUE software provides real-time monitoring and lets the user switch between single and multi-rail overcurrent protection on the fly. Modern Standby support enables fast wake-from-sleep.
