Corsair HX1500i Shift (2025) PSU Review

The new Corsair HX1500i Shift builds on previous models and brings new features to the table. It supports the latest ATX 3.1 and PCIe 5.1 platforms and the side-mounted connectors and built-in iCUE LINK System Hub offer more options for enthusiast system builders.

Technically, this CWT OEM partner design has already proven itself very capable with the previous HX1500i (non-Shift) model. Ripple suppression is excellent and it scores in the top 10% of units we have tested in recent years. Efficiency is also fantastic, hitting over 94% at around 50% load. Load regulation is tight and we appreciate that the unit has the same wide array of protection features sometimes missing on other units in the same class.

Again, we rate noise levels as some of the best we have recorded and the power delivery is smooth, even at loads up to 1200 watts. The unit remains almost inaudible at high loads from a few meters away. The latest NR140HP fluid dynamic bearing fan is just as good a performer as the earlier NR140P unit in the previous range. These fans are quite expensive to buy (around £20-£25 a fan) and I have bought a few myself for personal projects, that's how highly I rate them. One of the NR140P fans I have used has been running in a server now for more than 4 years, 24 hours a day.

It is good to see Corsair and CWT using high grade 105c Japanese capacitors from brands such as Nippon Chemi Con and Rubycon in these units. Build quality is extremely high quality across the PCB and component selection is reassuring.

A power supply of this quality doesn't come cheap, however, and Corsair told me the price will be £279.99 at launch. This is actually £20 less than the previous HX1500i that we reviewed back in June as it launched at £299.99. We do feel for the niche audience interested in a unit like this, that the quality justifies the price point.

Pros:

  • Delivers a sustained 1,500 watts without a problem.
  • 10-year warranty.
  • Zero RPM fan mode.
  • Highest grade 105c rated Japanese Nippon Chemi Con and Rubycon capacitors.
  • Extremely efficient.
  • High quality cables.
  • Very quiet, even at high loads.
  • Excellent default fan profile.
  • Cybenetics Platinum and A+ certifications.
  • Tight load regulation.
  • Fully modular.
  • Built-in iCUE LINK system hub.
  • iCUE support.
  • USB-C connector.
  • Shift design aids system builds.
  • ATX 3.1 and PCIe 5.1 compliant.
  • Super high grade FDB fan.
  • Expensive, but not super expensive like some we have reviewed recently around £500.

Cons:

  • It is not cheap, as you would expect.

KitGuru says: The Corsair HX1500i Shift takes the previous generation and improves on it with additional functionality such as the embedded iCUE Link System Hub and Shift side mounting connectors. The fully modular design is extremely efficient and the build quality is at the highest level.
