The Corsair HX750i is a high-performance 750W ATX power supply designed for demanding PC builds, gaming systems, workstation computers and enthusiast-grade setups where efficiency, reliability and clean cable management are essential. Part of Corsair’s premium HXi Series, this PSU combines 80 PLUS Platinum efficiency, fully modular cabling, quiet operation and digital monitoring support in a robust and professional design.

With 750 watts of continuous power, the HX750i is suitable for high-performance desktop PCs using powerful processors, dedicated graphics cards, multiple storage drives and advanced cooling configurations. Its 80 PLUS Platinum certification helps deliver excellent energy efficiency, reducing wasted power, heat output and operating noise compared with lower-efficiency power supplies.

The fully modular cable design allows users to connect only the cables required for their build. This helps improve airflow inside the case, reduces cable clutter and gives the system a cleaner, more professional appearance. The low-profile all-black cables are designed to fit discreetly into modern PC builds.

The Corsair HX750i is engineered for stable and precise power delivery. It supports ATX12V and EPS12V standards and is suitable for performance PCs where voltage control and long-term reliability are important. The unit uses high-quality internal components and is designed for continuous operation under demanding conditions.

For quiet performance, the HX750i includes a 140mm fan with fluid dynamic bearing technology and Zero RPM fan mode. At low and medium loads, the fan can remain off for near-silent operation, only spinning when cooling is required. This makes it a strong choice for users who want a quiet gaming PC, workstation or media system.

The HX750i also supports Corsair Link digital monitoring, allowing compatible systems to monitor key PSU information such as fan speed, power output, efficiency, voltage and temperature. Users can also manage fan behaviour and rail settings, depending on software and system compatibility.

With its 750W capacity, Platinum efficiency, modular construction and premium Corsair engineering, the HX750i is a reliable choice for users building or upgrading a high-quality PC power system.
