The PSU is nicely finished and looks pretty much identical to the one we reviewed back in July 2022. This is a large power supply measuring 150mm x 82mm x 200mm so will not be an ideal candidate for space restricted chassis designs.
The branding of the unit is clean and simple – with the product name and ‘Corsair' highlighted in a simple white colour.
One side is home the power connector and fan switch, along with the vented panel. This unit takes a high power C19 cable, which is included in the box. What is a C19 cable? they are designed to deal with higher levels of power – you can see in the image above the 3 power prongs are longer and flat. The C19 power connector is bigger and robust, with a rectangular shape and 2x rows of pins, typically four in total. This design allows the C19 connector to handle a higher maximum current.
The HX1500i can deliver 25A across the +3.3V and +5V rails. The primary +12V rail can handle a whopping 125A – which is considerable.
The HXi power supply is supported by Corsair iCUE software, although you really don't need to use it at all. As you will see later in the review, Corsair have pretty much nailed the fan profile at default settings.
That said, if you do want to give it a whirl, simply connect the USB C cable to the power supply and the motherboard. Launch iCUE and make sure you are running the latest updated version. From the home screen you then select HXi. From here you can adjust Fan Curves to create your own cooling presets. Sensor tiles are at the right and they can be moved around. You can also switch between Single Rail OCP and Multi Rail OCP in the software.
