Corsair HX1000i 1000W Fully Modular PSU

The Corsair HX1000i is a 1000W fully modular ATX power supply built for high-performance desktop systems. It meets the ATX 3.1 and PCIe 5.1 standards, making it ready for modern graphics cards and platforms. The unit carries 80 Plus Platinum certification for 92% typical efficiency. Digital control via CORSAIR iCUE software allows custom fan curves and real-time monitoring.

Build Quality and Connector Layout

A 140mm fluid dynamic bearing fan supports a Zero RPM mode that stops the fan at low and medium loads for silent running. Japanese 105°C electrolytic capacitors and a fully digital LLC resonant topology with DC-to-DC conversion deliver clean power and reduce coil whine. The fully modular design includes a native 12VHPWR 12+4 pin cable, two 4+4 pin EPS cables, four 6+2 pin PCIe cables, and eight SATA connectors across two cables. The housing measures 180mm deep.

Compatibility Checks Before Ordering

Verify that your case can accommodate a 180mm deep ATX power supply and that the 610mm 24-pin ATX, 650mm EPS, and 650mm 12VHPWR cables reach your motherboard and GPU routing paths. Confirm your graphics card requires a 12VHPWR connection or standard 6+2 pin PCIe plugs. Ensure your mains supply operates within the 100-240V, 47-63Hz input range.

Questions about this item

Will the 180 mm depth fit in a standard mid-tower case?

The unit measures 180 mm long; most mid-tower cases accept up to 200 mm, so it should fit, but verify your case's maximum PSU length before buying.

Does the included 12VHPWR cable support a PCIe 5.1 graphics card?

Yes, the box includes a 16-pin 12+4 cable rated for the PCIe 5.1 standard, so you can connect a Gen 5 GPU without an adapter.

Can I run the fan completely silent at idle?

Zero RPM mode stops the 140 mm fluid dynamic bearing fan at low and medium loads, giving near-silent operation until the load rises.
