Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.0 & PCIe 5.0 Compliant - Fluid Dynamic Bearing Fan - CORSAIR iCUE Software Compatible - 80 Plus Platinum Efficiency - Black

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!

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.

I love this thing. I'm not even using one of the 2025 GPUs you can't get right now anyways, but it is really well built and there's zero detectable weirdness or unexpected noises coming from it.

Works great. No power issues.

Great PSU and good build quality. Cant go wrong with it

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!

It seems to be a trend to simply not list the cables that will come with a PSU in product descriptions. It would've been good to know that this only comes with two PCIe 8-pin cables, because now my entire PC build is at a stand still. My GPU requires 3 PCIe connections in order to run, and this PSU is missing a third cable! The stupidest part is that the PSU is more than capable of running FOUR 8-pin cables to my GPU if I really needed it, but again, for some reason it only comes with two. Absolutely ridiculous for a modern PSU targeting high-end gaming PCs
