Corsair HX1500i 1500W Power Supply Review
Meet the 1500W Corsair HX1500i
Corsair upgrades its HXi series for the ATX 3.1 era
Corsair’s new 2025 range of HXi power supplies has arrived, and they have sent us their 1500W model in for testing. With its new 2025 HXi line, Corsair has revamped the lineup to meet the newer ATX 3.1 and PCIe 5.1 specifications. Furthermore, these new units ship with two 12V-2×6 power connectors, allowing them to power multiple high-end graphics cards.
The new HXi range is available in 1200W and 1500W forms. Today, we will be testing the new HX1500i.
The new HX1500i supports all of the features that you would expect from a high-end Corsair PSU. It’s Cybenetics rated, ATX 3.1 certified and PCIe 5.1 compliant. Remember, Corsair were the first PSU manufacturer to ditch the old 80 Plus standard in favour of Cybenetic’s more robust testing methods (learn more about that here).
With these PSUs, Corsair uses 100% Japanese 105°C electrolytic capacitors, features a Zero RPM fan mode, and offers fully modular cabling. The PSU is also backed up by a 10-year warranty.
Unboxing
Honestly, the unboxing experience for the HX1500i is pretty standard. Inside the box’s cardboard shell is the PSU and a box filled with cables. It doesn’t take long to get inside and retrieve your PSU. Great news if you want to build your system quickly. What we have here is packaging that’s designed to minimise waste and minimise the time it takes to get your PSU ready for your next PC build.
Size and aesthetics
If you are looking for a flashy power supply, the HX1500i isn’t it. It’s a standard “black box” power supply, and unashamedly so. Since most cases cover up power supplies, this will be a non-issue for PC builders. There’s a reason why RGB power supplies are rare.
Note that the HX1500i is 200mm long. This places the HX1500i on the longer side of the ATX power supply spectrum. This could present case compatibility concerns for some users. That said, the ATX standard allows for lengths of up to 230mm, and many PC cases are designed to accommodate this maximum length. Regardless, buyers of this PSU should ensure that it will fit inside their system.
Unique features
Like Corsair’s other i-series power supplies, the HX1500i support Corsair’s iCUE software. This allows users of this power supply to monitor their power usage and other PSU data. This kind of functionality is rare for modern PSUs, although it is a valuable feature for anyone interested in seeing how much power their system uses during specific workloads.
Modular cables
The HX1500i is a fully modular power supply. This allows PC builders to only use the cables they need to build their systems. This reduces cable clutter when building a PC, eliminating the need to hide excess cables.
Note that this PSU does not have 12V-2×6 power connectors. This PSU’s includes 12V-2×6 power cables that connect to two of this PSU’s PCIe/CPU power headers.
As expected from a 1500W PSU, the HX1500i uses a chunky C19 power cable. That’s to be expected from a PSU with this wattage. It’s certainly a step up from the standard “kettle lead” that most PSUs come with.
Cables
As mentioned before, the Corsair HX1500i is a fully modular power supply. The PSU uses Corsair’s Type-4 cables. With the HX1500i, all cables were debossed, and the primary cables included integrated cable combs. The only internal cable that isn’t debossed it this PSU’s USB Type-C cable, which makes sense as it isn’t a power delivery cable.
Below is this PSU’s included 24-pin cable.
The HX1500i’s 2025 incarnation ships with two 12V-2×6 power cables, each featuring a dual-colour connector. These dual-colour connectors make it easier for users to see if their cables are fully seated.
Included cables

Pricing
Corsair’s new HX1500i power supply is available for £299.99 in the UK.
