1000W Platinum ATX Power Supply

The Corsair HX1000i delivers 1000 W of continuous power through an ATX12V v2.4 and EPS12V 2.92 design. It carries 80 PLUS Platinum certification at 92% efficiency and operates on 100 to 240 V input at 47 to 63 Hz. A single 140 mm fluid dynamic bearing fan provides thermally controlled cooling.

C-Link Monitoring and Full Modular Cables

Corsair Link Digital support lets you monitor performance, switch between single and multi +12V rail modes, and adjust fan speed from the desktop. The fully modular, low-profile cable set includes eight 6+2-pin PCIe connectors and twelve SATA power connectors for clean routing. All Japanese 105°C capacitors are used throughout.

High-End Multi-GPU Builds and Silent Operation

This unit suits enthusiasts building SLI or CrossFire systems who want tight voltage regulation and near-silent Zero RPM fan mode at low loads. The 180 mm depth fits many mid-tower cases, but builders with compact chassis should verify clearance. Anyone needing only modest wattage can consider lower-capacity models.
