For the record, I am reviewing the: Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe 5.1 Compliant - Fluid Dynamic Bearing Fan - CORSAIR iCUE Software Compatible - 80 Plus Platinum Efficiency - Black This is my third Corsair power supply. The first died in my other system after about 3 years. I then purchased one that was slightly more powerful and it has lasted more than 10 years and still running. I think that Corsair goes above and beyond when they put their packages together, you get all the cables you could ever need, and then some. The I have two bags full of extra cables that I am holding on to just in case I ever change things. I have to check from time to time to make sure the fan is working on the PW Supply, as it only comes on once in a while. I guess I have over killed my system with power but since I am running a really nice video card and a whole bunch of fans, I added everything up and then added an extra 100 watts just for safety. I don't want to over tax my system and then burn it out. This this saves me power by not using it unless it is needed. I love the per-wraped cables, and cable management is not bad with these as they do bend easily. The quality of all the connectors is top notch and I have not had a single cable go bad or have any problems. Installation was simple, and I love it. I don't think you can go wrong with a Corsair PS. Just do the math and make sure you get the correct one.

Great power supply. I haven’t had any issues and I feel confident it will be able to handle a GPU refresh as soon as the AI bubble bursts and us peasants can get video cards again.

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 power The Zero DB fan, which is my top feature. Its internal components are of excellent quality Full 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.

I bought this CORSAIR HX1200i to ensure the power of my new ultra-high-end gaming configuration, and I couldn't be more happy with the performance. It is a component that, although not seen much, is vital, and this source does everything well.

This was exactly what I was hoping for, but it was short one cable for my GTX 5090 graphics card. 3 of the 4 cables were exactly right, but the fourth had a pigtail on it that I couldn't hide, but seemed to function fine.

The Corsair 1000w power supply is a high-performance, fully modular power supply that stands out for its reliability and ultra-low noise operation. The compatibility with ATX 3 and PICE 5 makes it future-proof. I assembled an i9-14900kf PC along with a 4090 video card for a computer needed to do 3D rendering. One of the key features of this power supply is its building quality. The fully modular design simplified cable management, reducing clutter and improving airflow within the case. The power supply has been stable and efficient; with a platinum certification, it guarantees high efficiency, low energy consumption, and reduced heat. The noise level while running CAD applications has been very low when running medium loads. Overall, the Corsair power supply has been an excellent choice, and I would recommend it to anyone building a high-end system.

I've had this thing in my computer for about 6 months now. Have not had any issues with it. This power supply was way bigger than I was anticipated going into my case but it fit just fine and I believe my computer is not even using a quarter of the power that this PCU generates for my computer
