The CORSAIR HX1500i (2025) is a premium power supply designed for high-end PCs that demand clean, stable, and efficient power. With Cybenetics Platinum certification, it delivers up to 92% efficiency, reducing heat and energy waste. Its fully modular design lets you attach only the cables you need, keeping your build tidy and airflow unobstructed.
This PSU is Intel ATX 3.1 certified and PCIe 5.1 compliant, meaning it natively supports the latest graphics cards with the 12V-2x6 connector. The included cable provides up to 600W to a single GPU, minimizing the need for adapter mess. It also handles transient power spikes effortlessly, preventing system shutdowns even under heavy gaming loads.
The 140mm fluid dynamic bearing fan runs silently while keeping components cool. At low and medium loads, the fan completely stops thanks to Zero RPM mode, making the HX1500i ideal for quiet builds. You can set your own fan curves via CORSAIR iCUE software for precise cooling control.
Unlike traditional PSUs, the HX1500i has a fully digital platform that communicates with iCUE. You can monitor real-time power draw, efficiency, and fan speed, and even switch between single and multi-rail overcurrent protection on the fly—giving you flexibility for overclocking or maximum stability.
Japanese 105°C-rated electrolytic capacitors ensure stable power delivery and long lifespan, even in demanding environments. The fully modular black cables make building clean, high-performance systems straightforward.
Fully modular cabling lets you use only the wires you need for a cleaner build.
ATX 3.1 and PCIe 5.1 compliant, with a native 12V-2x6 cable for modern GPUs.
iCUE software enables custom fan curves, power monitoring, and single/multi-rail switching.

Unlock the full potential of your build with the HX1500i's digital power monitoring. In iCUE, you can track power usage per component, allowing you to optimize settings for efficiency or performance. And with dual-rail/overcurrent protection, you can decide between maximum safety or headroom for extreme overclocking.
Install CORSAIR iCUE, connect the PSU's USB cable to your motherboard, and it will appear as a device. Go to the Cooling tab, enable custom fan curve, and set your preferred temperature/load points.
Zero RPM mode stops the fan at low and medium loads for silent operation. It's enabled by default, but you can disable it in iCUE if you prefer constant airflow.
Yes, it includes a native 12V-2x6 cable that delivers up to 600W, perfect for flagship GPUs like the RTX 4090.
I bought this for future-proofing my rig. It's super quiet, and the iCUE software gives detailed power stats. The modular cables are high quality. It's expensive, but you get what you pay for.
Cybenetics Platinum rating is no joke. This thing runs my RTX 4090 and i9 without breaking a sweat. The fan is silent even under load. Totally satisfied.
The PSU works flawlessly, and the build quality is excellent. The only complaint is the price, but for 1500W and ATX 3.1, it's expected. If you need the wattage, it's worth it.
I can't hear the PSU at all. The modular cables make cable management a breeze. The iCUE integration is a nice bonus. Highly recommend for high-end builds.
The hardware is fantastic - quiet, efficient, and stable. However, the iCUE software sometimes fails to detect the PSU, and the fan stops spinning then restarts. Not a big deal, but annoying.
I bought this for the new GPU connector, and it's perfect. The 12VHPWR cable that's included is sturdy. The PSU runs cool and quiet. It's a beast.
Upgrading to this PSU eliminated all my power issues. The cables are flexible and the SATA cables are long enough. The platinum efficiency means lower electricity bills, even under load. Excellent product.
The PSU is fine, but I didn't notice any difference from my previous 1000W unit. It's extremely expensive, and the fan noise is there if you stress it. I expected more for the price.
This is the best PSU I've ever used. The quality is obvious. The 10-year warranty gives me peace of mind. If you're building a pro-level PC, this is the one.
The PSU runs great and is quiet. The iCUE connectivity is a gimmick for a PSU, in my opinion, but it's there if you want it. The cables are a bit stiff, but manageable. Overall, happy.
Installed it and forgot about it. It's been running my system for months without a hitch. The fan is completely silent at idle, and it stays quiet under load. Highly recommend.
I was hesitant about the price, but it's worth it for the reliability. The 1500W will handle anything. The cables are premium, and the PSU looks sleek. Very satisfied.
