HX1500i (2025) ATX 3.1 PCIe 5.1 Ready 1500W Power Supply – Black

The Corsair HX1500i is hands down one of the best power supplies I’ve ever used. It’s incredibly powerful yet surprisingly compact, which made installation much easier than I expected for a 1500W unit. Despite the huge power output, the PSU runs basically silent even during gaming and stress tests, the fan barely kicks on. The cables are really nice quality too. They’re braided, flexible, and clean, which makes cable management so much easier. Corsair also includes every cable you could possibly need and extra options for different setups, so you’re fully covered no matter what your build requires. Power delivery is stable, efficiency is great, and iCUE monitoring works perfectly for checking power draw and temps. Overall, this is an incredibly well built, reliable, and overkill in a good way PSU. If you want something small, powerful, silent, and loaded with premium braided cables, the HX1500i is perfect.

Back in March of 2025, I was fortunate to snag an ASUS RTX 5090 graphics card for only $2300. In order to power that beast, I need another beast capable of putting out more than 1200 watts to be on the safe side. I decided to go with this Corsair HX1500i fully modular PSU. One nice thing about the HX1500i is that is follows the very latest ATX 3.1 and PCIe 5.1 standards for modern PSU design. This HX1500i does come with one 12VHPWR cable that can deliver over 800 watts to an RTX 5090 graphics card that is being overclocked if needed. I have put this HX1500i to the test by playing both Cyberpunk 2077 in 8K with RayTracing Overdrive mode (Path Tracing) and with DCS World using the Quest Pro in VR. The HX1500i remains very steady under load while also keeping noise to a minimum. So far, after almost a year, the HX1500i has been a five star experience.

Powerful and Super Quiet this PSU rocks. Save for one feature I would have liked to see is a power on LED light. The company states the fan will spin temporarily when you plug it in to let you know it is receiving power but an LED light would be exact and on and noticable every time. If your not looking at the fan you might miss the power on spin, then you think the PSU has an issue. Other than that small detail, it is SUPER Quiet and very powerful, great power saving technology as well. If your running power hungry equipment in your pc, this is a fantastic PSU to handle the load and doing it quietly. Cables are high quality and you can connect the PSU to a USB header to monitor your power as well, pretty slick feature I gotta say.

Power supply is fantastic. It has supplied more than enough power to my high powered gaming system. Highly recommended.

Excellent quality, would definitely buy again. Only complaints is that the 12 volt high power GPU cables are a little thin, but CableMod fixed that for me. Overall very nice design, quiet, and excellent quality. Performance is on par with higher units (definitely better than the 5x more expensive ASUS Thor that it replaced after the third RMA), lol. The power supply is consistent with less dips under load than expected, and honestly I have never heard the fan at all. Definitely quieter on the coil whine than other brands. Even pushing close to the 1500watt limit it is quiet and strong for hours on end. Would definitely buy again!

It powers my RTX 5090 rig without a hitch. Fit easily into my old Corsair Obsidian 800D case, plenty of cables, extremely quiet, and has a ton of connectivity for my 5090, AIO, (2) Raid arrays, (2) NVME SSDs, and case fans.

It is obviously a very good power supply, but I hate that they came so late with a power supply that has the 600 watts PCIExpress connector for the graphics card. I was forced to buy a new one while my previous power supply of the same model was fine, but wasn't equipped with one. The other thing that is irritating with corsair is their proprietary connectors that prevent you from plugging "standard" cables. Consequently, you can't buy "design" cables if you are planning to use a Corsair power supply. It is more quickly annoying that you would think if your intention is to build a white computer, because all their cables are black and you'll just be stuck with that. A good thing though is that they improved the cables, they are not as bulky and ugly as they used to be with previous versions/models.

Bought this supply to upgrade from an RM1000E which was running close to 900 watts during intense gaming (Core i9-14900KS, RTX4090 24GB OC,128GB DDR5-6800, 1x Gen 5 M.2 NVME 2TB drive, 2x Gen 4 M.2 NVME 2TB drives, 1x SATA 6Gb 4TB, and a metric crapton of RGB fans) which was a little close to the edge for me. Installed the HX1500i in a little over an hour, most of which was extricating the original power cables. I used hardly half of the new power cables and appreciated how nice the new cables look with the included combs. System came right up with the HX1500i, iCUE promptly discovered the new supply and installed support for it, then I set up a quasi-linear fan curve and marveled at how quiet this beast can be. Love being able to monitor pretty much every aspect of the HX1500i via iCUE. As has been noted the HX1500i is long - it's nearly twice the length of the RM1000E it replaced. Fortunate I have an oversize mid-tower case (Corsair 5000T) which has plenty of room for lengthy power supply but I could see how the supply could be an issue for smaller cases. Also, the AC line cord provided is massive and uses a different PS-end connector from "normal" supplies - the lugs are huge compared to more typical connectors. Cheers!

Super silenciosa! Muy buen producto

I purchased this power supply for my RTX 5090. My previous EVGA 1300W G2 lacked the native connector, so I had to use the adapter, but I had seen people having melting issues with the included MSI adapter. I decided to purchase this power supply based on the testing done by Cybernetics. This PSU comes with dual 12V-2x6 cables (and ability to use both of them at the same time) which I wanted in-case the RTX 6090 requires dual 12V-2x6. The install was pretty easy. I went fan up (towards the GPU) and I noticed only 3 screw holes were present, though the PSU is just fine with 3 screws, it's glued to the chassis. The cables are adequate length for regular ATX cases, I noticed every cable had a nice click except the 24 pin motherboard which was a bit faint. The 12V-2x6 clicked nicely into my MSI RTX 5090. The pins on the 12V-2x6 had normal wiggle variance as per Corsair's specs. And overall the cables were flexible and of good quality. I did find with my case the included SATA power cables weren't long enough for the back mount of my HDDs, so I had to use two of them, if you have a regular case you should be fine, my Fractal Define S has the HDDs behind the motherboard tray, and not in any cages. One small annoyance was the lack of a PSU bag for the cables, and there is no included manual, both of which came with my EVGA 1300W G2, the box seems of good quality though, so it's not all bad. I did like the included zip ties which helped with cable management, I chose not to use the combs since my case doesn't even have a side panel window (which I prefer). I can't even hear the power supply when it's in use, so that's nice, not that I ever noticed my other PSUs fan either. One of the reasons I went with Corsair was the use of two 8 pins on the power supply side for the 12V cable (two 8 pins means a perfect amount of pins into the 12V-2x6 cable, and the 12V-2x6 has the jumper thing telling the GPU 600W is a-okay to draw from). I prefer this due to how small the regular 12V-2x6 is compared to two 8 pins which I think would make a more stable connection/last longer while still being ATX3/3.1. Another reason was the warranty, which while is standard at 10 years, I only ever heard bad about other manufacturers getting in-contact with, whereas Corsair is a known entity. The final reason being Jon Gerow (JohhnyGuru) who, when I purchased my EVGA 1300W G2, was the authority on PSUs and testing, has been working at Corsair for a very long time, I trust him and the team at Corsair. I'm perfectly happy so-far, I didn't run in to any issues, the cables were nice, the PSU instantly worked, if I have any issues or complaints I will update this review. I would recommend the HX1500i (2025).

Tem funcionado bem e veio com o cabo de força. Única coisa que me incomodou um pouco foi o modo como o cabo da placa-mãe é, com uns fios sobre outros ao invés de estarem mais organizados

This is my second HX1500i but the 1st one was an older version. I really love the fact that it is ATX 3.1 and PCIe 5.1 compliant. The included cables also seem to be of a better quality than my older one and they are more flexible. The price has also dropped because of the Icue Link/Shift version that's out now which is $160 CDN more expensive than this version which is not justifiable for me right now. I'm very happy with my purchase.
