CORSAIR HX1500i 1500W 80+ Platinum ATX 3.1 Fully Modular Power Supply

The CORSAIR HX1500i 1500W is a flagship-tier power supply built for builders who refuse to compromise. As a member of the premium HXi Series, it carries Intel ATX 3.1 certification and PCIe 5.1 compatibility, making it a future-ready foundation for today's most demanding graphics cards and processors. At the heart of its connectivity story are two dedicated 12V-2x6 GPU power cables with dual-colour connectors that provide a clear visual confirmation of a secure seat — an important safety detail when running high-wattage discrete graphics. Beyond those, the fully modular harness means you route only the cables your build actually needs, reducing clutter and improving airflow inside the chassis. Cooling is handled by a Fluid Dynamic Bearing fan that operates silently under light to moderate loads thanks to a Zero RPM mode, which keeps the fan completely still until thermal conditions demand otherwise. When the fan does spin up, the FDB mechanism ensures smooth, low-noise operation throughout its lifespan. Long-term reliability is underpinned by 105°C-rated Japanese electrolytic capacitors across every rail — an industrial-grade standard that resists heat-related degradation over years of continuous use. Efficiency is independently validated through Cybenetics Platinum certification, reflecting sustained output efficiency up to approximately 90%, which translates to less heat generated, lower electricity draw, and quieter overall system behaviour. For enthusiasts who want deeper control, CORSAIR iCUE software integration lets you monitor real-time power consumption, toggle between single-rail and multi-rail operation, and adjust fan speed directly from the Windows desktop without opening the case.
