Know before you buy
Yes, the HX1500i is fully ATX 3.1 and PCIe 5.1 compliant. It is designed to handle the power requirements of the latest high-performance GPUs without needing extra adapters.
The unit features a Zero RPM mode, which keeps the fan completely off during low and medium loads for silent operation. The fan only spins up when the power supply reaches higher temperatures or loads.
The HX1500i provides a full 1500W output when connected to a standard 115V–240V outlet. If you are using a 100V outlet, the maximum power output is limited to 1200W.
iCUE allows you to monitor power draw, efficiency, and temperatures in real-time directly from your desktop. It also gives you the ability to toggle between single and multi-rail overcurrent protection modes.
Yes, it is fully modular, meaning every cable can be detached from the unit. This makes it much easier to manage cables and keep your PC build clean, as you only need to plug in the cables you actually use.
The unit is built with 100% Japanese electrolytic capacitors, which are known for their high reliability and longevity. This build quality is why Corsair backs the unit with a 10-year warranty.
