I upgraded from a Thermaltake 600W PSU, which was struggling to cope with my hardware needs due to a mixture of mechanical, SSD and M.2 NVME drives coupled with a 6700XT and a Ryzen 5900x processor.Despite my new RTX 4070 graphics card consuming less power than the previous 6750XT an upgrade was due. I initially intended to opt for the 850 RMx series. However, I'm extremely satisfied with my choice of the 1000HXi, which provides extra capacity. The power supply installed in my Thermaltake Core V21 case very easily without any reconfiguring.My PC, equipped with a Ryzen 5900x, is an occasional gamer but primarily used for running VMs and containers, meaning it's on for a significant part of the day. Although this PSU may have a higher upfront cost, its superior efficiency rating will eventually lead to savings compared to less efficient 850 RMx PSU I was initially considering. Both have a lengthy warranty period worth considering in your decision-making process. However, the extra headroom and efficiency were deciding factors for me.Advantages of this PSU include:Plenty of powerThe Zero DB fan, which is my top feature.Its internal components are of excellent qualityFull modularity is a major plus.Many reviews rank it as an A-tier power supply.While I didn't require the iCUE software, it's a nice bonus.It's also somewhat future-proofed with ATX 3.0 & PCIe 5.0 ratings.On the downside:No instructions were provided, and the QR code on the box for the manual didn't work.Also, the cables are somewhat rigid, but they still seem to be of high quality.In conclusion, I would wholeheartedly endorse this PSU and wouldn't hesitate to purchase it again.

This power supply not only looks great but it works even better. The modular design is what you want for your build so as to not have a bunch of extra wires hanging out in your case. It even has the 12v power cable for the new video cards. Plus you can even use the included USB-C to USB 2.0 header cable to enable viewing stats and controlling fan speed and curves via the Corsair ICUE Software. In order to use this feature, however, you will need a free USB 2.0 Header on your motherboard. For me I had to purchase a Corsair USB 2.0 4 Port Hub as well as a SATA Extension Cable to accomplish this. Those are super easy to install and relatively inexpensive. Overall I really like this power supply but I may be a bit biased having used Corsairs in most of my builds. Do I recommend it? That would be a yes!

Bought this to replace a cheaper RGB model from a different company which had rave reviews, but died after just a few month. Just unpacking the Corsair I could see the difference in build quality. No issues so far, I highly recommend Corsair.

Works flawlessly and is crazy quiet. The only issue I had was that it was a lot longer than most of the PSU's I'm used to and it made some cable routing a bit difficult. I would recommend a larger case for better cable routing.

This PSU is absolutely amazing! I’ve never heard its internal fan – it's incredibly quiet. Mine came is ATX 3.1 certified, and I couldn’t be more pleased with its performance. I'm truly impressed with this product and would highly recommend it!

When building my new PC, I wanted to make sure that my investment was going to be powered and protected by a quality PSU, especially after having one take equipment with it in the past.1000 Watts is plenty for almost all modern builds, this has support for the newest PCIe standards, and the digital management makes it easy to keep tabs on your systems performance and overall power usage.

Solid power supply. This thing is a beast. The modularity is great, and it runs well.

After installing the new Corsair HX1000i to replace a failed power supply, the problems started.The PSU fan turns, lights for USB ports etc. light, mother board lights are on, Wi-Fi antenna lights turn on, GPU card fan runs and supplemental internal fans work. However, the BIOS never boots, no beeps sound when I turn on the power. I contacted Corsair customer support on 11 Feb explaining the situation. There response was to reseat the memory, which I did with no effect. Customer Support then started asking about my old power supply, could I re-use it? I said no it died. That was on 15 Feb and I have heard nothing from them as of 19 Feb. Five days is a ridiculous amount of time to wait for a response from Corsair. I sent another message on the same ticket detailing additional trouble shooting steps I have tried, including removing the memory entirely and disconnecting everything except the motherboard. No response. Corsair has by far the worst customer support I have encountered in twenty plus years in the IT field. I do not recommend purchasing any of their products based on my experience.I will beg and plead with Amazon to be allowed to return this defective power supply, but am not holding out much hope based on their return policy for electronics. So, I’m out $250.00, two weeks of my time and I still don’t have a functioning computer.

El cable ATX de 24 pins tenÃa un error de fábrica, haciéndolo imposible de conectar, tuve que comprar un remplazo, fuera de eso el producto es lo que es.

I'm really happy with this PSU. I bought it to replace my 14 year old AX850 power supply which was still working. I wanted a new power supply that had a 12VHPWR connector for my new 4070ti instead of using the adapter harness that came with the GPU. And I thought it was time to replace that aging power supply.I used this PSU in a Fractal North case and the new PSU is a bit longer than the previous AX850. Not much but enough that tucking in extra cord length behind it was difficult at times. However, it all worked out in the end.I wish the cables were individually sleeved. I had bought some individually sleeved cables with my AX850 but they wouldn't work with the HX1000i as the latter is Type 4 cables and the AX850 is not. So I'll have to buy a sleeved cable kit or at the minimum a couple of sleeved cables that you can see through the cases windowed panel.Overall, a good power supply that is quiet and so far has been very reliable just like its older brother.

I like the 12WHR pin and the CPU cable has 2 attachments connected which works well for modern boards because motherboards nowadays needs 2 x PCI-E.Helpful for cable management.Has enough power to power a 4090 and Ryzen 7950x3d so no complaints. Should be good for a 8090 even since total power draw doesn't seem to even get close to capping out at the 1200w on the psu.

Easy to install. Great power supply. No issues. Highly recommend if 1000W PSU is required.
