Designed for modern desktop builds, this 1000W semi-modular power supply delivers reliable power delivery to high-demand gaming rigs and workstations. Built to Intel ATX 12V v3.1 standards, it provides direct compatibility with modern hardware while fitting standard ATX chassis thanks to its compact 140 mm depth.

The unit features native PCIe 5.1 support via a dedicated 12V-2x6 cable delivering up to 600W for graphics cards such as NVIDIA GeForce RTX 40 and RTX 50 series, alongside traditional 8-pin PCIe connectors. An 80 PLUS Bronze rating ensures up to 90% efficiency under typical load to keep heat generation low.

Cooling is managed by a 120 mm silent fan equipped with an advanced low-voltage Thermal Manager to balance temperatures and noise. Complete CircuitShield industrial safeguards provide full defence against electrical anomalies, including over-current, short-circuit, and power surges.
