Overview

1000 watt ATX 3.1 80+ Platinum power supply

Corsair HXi Series ATX 3.1 fully modular power supplies provide an 80 PLUS Platinum certified power supply with the performance of a 140mm magnetically levitated fan. Turn on your computer faster and consume less energy with Modern Standby mode. Zero RPM mode ensures almost inaudible operation at low and medium loads. Corsair iCUE software lets you configure custom fan curves, monitor and adjust power settings, and much more with a fully digital platform.

Key Features

  • Fully modular cabling: Connect only the cables your system needs, making it easy to design a clean, tidy system.
  • ATX 3.1 standard : Highly reliable and energy efficient, HXi series power supplies are officially certified for ATX 3.1 compliance with a PCIe 5.1 GPU cable (12V-2x6) for use with recent graphics cards.
  • 140 mm magnetic levitation fan : Offers virtually inaudible fan performance.
  • Zero RPM fan mode: At low and medium loads, the cooling fan switches off completely for silent operation.
  • 80 PLUS Platinum certification: Guarantees efficiency of up to 92%, for a very significant reduction in power consumption, noise and temperature.
  • 100% Japanese 105°C electrolytic capacitors: The use of high-quality internal components ensures a stable power supply and long-term reliability.
  • All-digital platform: Resonant LLC topology and DC-DC conversion ensure a reliable and consistent power supply, and reduce noise and coil hiss for quiet operation.

    Superb supplies

    It's a superb power supply, it's 1000w, 80PLUS PLATINIUM and atx 3.1. it's perfect and top of the range for my future configuration which will be based on a latest generation ryzen 9 x3d with a pcie 5.0 graphics card from amd, no doubt the rx 9070 xt. In addition to that the delivery was as usual very well. Oh I forgot but the CORSAIR HX1000I is backlit it's sublime!

    Thank you LDLC for offering us very high quality components.
