1200 W ATX 3.1 Power Supply

The Corsair HX1200i delivers 1200 W of continuous power through a fully modular design. It targets builders of high-end workstations and multi-GPU systems who need reliable output and clean cable management. ATX 3.1 compliance ensures compatibility with modern PCIe 5.1 graphics cards and Intel platforms. The unit includes a native 12V-2x6 cable for direct GPU connection.

Sustained Load Behaviour

Industrial-grade 105°C Japanese electrolytic capacitors maintain stable voltage during extended heavy workloads. The power supply holds 80 PLUS Platinum certification with up to 92% efficiency across typical operating ranges. iCUE software allows on-the-fly switching between single-rail and multi-rail overcurrent protection modes. MTBF is rated at 100,000 hours for long-term dependability.

Thermals, Noise and Power Draw

A 140 mm fluid dynamic bearing fan runs in Zero RPM mode at low to medium loads for near-silent operation. Cybenetics A noise certification confirms quiet acoustic output under normal use. High efficiency reduces waste heat, keeping internal temperatures lower during typical gaming or productivity sessions. The fan curve is fully customisable through iCUE for precise thermal control.

Questions about this item

How loud is the 140 mm fluid dynamic bearing fan when the HX1200i runs continuously at high load?

The unit carries a Cybenetics A noise rating and a Zero RPM mode that keeps the fan off at low to medium loads, so sustained high-load operation stays very quiet.

Which cables must I already have to use the fully modular CP-9020307-NA in my build?

No cables are required beforehand; the PSU ships with every modular cable needed — 24-pin ATX, two EPS, five PCIe, eight SATA and six PATA — so you connect only what your system uses.

Will the 12V-2x6 connector on this ATX 3.1 unit work with my older graphics card that uses standard 8-pin PCIe plugs?

Yes. The supply includes five 6/8-pin PCIe cables that fit both older 8-pin cards and the newer 12V-2x6 interface, so existing GPUs work without adapters.
