HXi Series power supplies give you extremely tight voltage control, virtually silent operation, and a fully modular cable set. With all Japanese 105°c capacitors, they’re a great choice for high performance PCs where reliability is essential. 80 PLUS Platinum efficiency reduces operating cost and excess heat, and together with Zero RPM Fan Mode technology, gives you virtually silent operation.
With Corsair Link Digital support, you can monitor power supply performance, toggle single rail or multi rail mode, and control fan speed directly from your desktop. And, the fully modular, low profile cable set makes builds and upgrades easy, with clean, great-looking results.
High Performance Design
The HXi series is designed for use in truly remarkable PCs with a focus on excellent electrical performance for voltage regulation, noise, and ripple.
80 PLUS Platinum certified efficiency
80 PLUS Platinum certification guarantees 92% efficiency and silent operation at typical loads.
Flat black, Low-Profile Modular Cables
You can remove unneeded cables and leave them in the box for fast, easy, and great-looking builds.
750 watts of reliable, continuous power delivery
The HX750i power ratings are continuous, not peak, for superior protection for your valuable PC. Corsair uses high-quality internal components like 105°c rated Japanese electrolytic capacitors and is guaranteed to deliver clean, stable, continuous power even at a server grade 50°c ambient temperature.
