    • High performance, highly efficient and very quiet.
Size: 1000 Watts
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. ... show more

    • Great Power Supply with Silent Operation, ICUE Control, and a 12v Video Power Cable

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! ... show more

    • Best Power Supply I have used.
Size: 1000 Watts
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. ... show more

    • Great PSU, but long.
Size: 1200 Watts
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.

Silent, cool, fan stops without load. Only few things a wanted to point out: 1. ATX cable is extremely difficult to bend it to 180 degrees 2. I wasn’t managed to find any cable specification to decide if I can use 1 cable for RTX3090 or I need two separate ones. Came up with two cables, which looks slightly worse because of unused connector. ... show more

Very good quality Power Supply for Gaming PCs, my experience has been very stable and have no issues overclocking my cpu and gpu with plenty of headroom.

    • Low rating due to item craftmanship (Read Review)
Size: 1000 Watts
I returned this power supply upon opening it. When I took it out of the box, I hear something rattling around inside the P.S. When I turned it over, a ball of solder fell out. Inspecting the solder, it was smooth and shiny except for the flat bottom where it had been soldered, which was coarse and rough... obviously a cold solder joint. I decided to box it back up and return to Amazon and get another one. I did order the same Brand and model, as I really like Corsair products. Other than that issue, this appears to be a quality made product. I will right a review when I receive my new unit. ... show more
