1200W 80 PLUS PLATINUM ATX supply

The Corsair HXi Series HX1200i is a fully modular ATX12V and EPS12V power supply rated at 1200 watts. It carries 80 PLUS PLATINUM certification for 92% efficiency at typical loads. A 140mm fluid dynamic bearing fan supports ZeroRPM mode for silent running at low demand. Corsair Link integration provides monitoring and fan-speed control via a USB 2.0 interface.

High-output builds needing full modularity

This unit suits enthusiasts assembling multi-GPU rigs or workstations that can draw several hundred watts from the +12V rail. The single-rail design simplifies cable planning while delivering up to 100A on +12V. Builds with modest power requirements will not benefit from the headroom and may prefer a lower-wattage model.

Single +12V rail rated at 100A

The defining specification is the single +12V rail capable of 100A continuous output. If your graphics cards and CPU combined demand approaches that limit, this supply delivers the current without rail-balancing concerns. If the total +12V draw stays well below that figure, a smaller unit will be more cost-effective.

Questions about this item

Which capacity should I pick for a multi-GPU build?

The unit delivers 1200 W on a single +12 V rail rated at 100 A and provides eight 6+2-pin PCIe connectors, so one model covers SLI or CrossFire configurations without needing a second PSU.

What does the 80 PLUS Platinum rating mean once the supply is installed?

It guarantees 92 % efficiency at typical loads, which lowers waste heat and keeps the 140 mm fluid-dynamic-bearing fan off completely during light work thanks to ZeroRPM mode.

What interface does the monitoring link use and what does it control?

A USB 2.0 port connects to Corsair Link software, letting you watch voltages, adjust the fan curve and switch between single-rail and multi-rail operation from Windows.
