3 years have passed since my review of the HX1500i power supply and today we take a look at the updated 4th Generation unit for 2025. These new units are Platinum Certified, fully modular and are clearly targeting the high end audience rocking an RTX 5090 or similar graphics card. Corsair are offering two models, a 1200W and a 1500W – the latter of which we are reviewing today.

As well as a new modified design, Corsair have updated the 2025 model with braided cables with low profile combs and the PSU ships with dual 12V-2×6 cables.

Both of these new 4th Generation HXi power supplies have achieved the excellent Cybenetics Platinum certification – which is a much more important certification than the dated 80 Plus platform. Both supplies are ATX 3.1 and PCIe 5.1 ready and feature a 140mm Fluid Dynamic Bearing fan as well as 105c rated Japanese capacitors. Corsair are offering a full 10 year warranty with both of these new power supplies.

If you don't know already, the ‘i' in the product name means they support iCUE (Corsair Software) so you can get full Digital control through the desktop software.

This software allows you to override the default settings and create custom fan profiles as well as monitoring power settings. You can also use the software to switch between single or multi rail overcurrent protection (OCP). Corsair are working with Channel Well Technology (CWT) as the OEM manufacturer of these power supplies, in partnership with their own engineering team behind the scenes.

Includes:

• Compatible with next-gen GPUs
• Dual 12V-2×6 cables
• Fluid Dynamic Bearing fan with Zero RPM mode
• 105°C rated 100% Japanese electrolytic capacitors
• 10-year warranty
• Intel® ATX 3.1 certified, PCIe 5.1 compatible
