Customer Ratings & Reviews

It's quiet, easy to install, and powerful. Corsair has been in the business for some time now and they know how to make great power supply units. It has good air vent coverage for keeping itself cool and easy enough to blow away dust when the time will come to clean it. Connection of the custom cables seems good. I did have to push hard for the custom cables to be fully secure, but that's pc life! I've had lots of experience with Corsair PSU's and they have always performed well and they're always my first stop when it comes to power needs.

Solid power supply. Sturdy construction and quiet while at high wattage work loads. The included cables are also well made. This series of PSUs are A-Tier

I bought this to replace an old 850W PSU that popped while I was using it. So far this one is working perfectly. It was easy to install, and since it's fully modular I don't have a bunch of extra cables in my case to try to hide. My PC has 4 sticks of RAM, a dedicated GPU, and AIO cooler for the CPU, 3 220 mm fans, a PCI-E sound card, 4 SSDs, and 4 hard drives and this PSU has enough power for all of it.

Excellent high power, modular PSU. Very quiet. Not a bargain, but not overpriced either. Still need to purchase 12VHPWR connector separately.

Put this in my new PC build. Handles powering the 3070 no problem. Easy to install, use, and works as should. Came with all the cables I needed and then some.

This Power Supply delivers exceptional performance and reliability. Its sturdy build quality ensures longevity, while efficient cable management keeps the system tidy. Handling high-demand tasks effortlessly, it operates quietly, making it ideal for gaming and intensive applications. Highly recommended for enthusiasts seeking a dependable power solution.

This power supply is an amazing unit. It is super quiet, has enormous amounts of cables for connections if you need it, and best of all, it fit perfectly in an old Alienware desktop chassis to bring that unit back to life! I am very pleased with this purchase and I'd say you cannot go wrong with this unit in either the 1000W or 850W configuration. I went with the 1000W since that is what was in my old Alienware but I probably could've gotten away with 850W.

Wish it came with 3 pcie power cables. Needed 3 type 4 cables to connect to 3090ti power splitter. Luckily I had a COMPATIBLE pcie cable laying around and this psu handles my 13900k and 3090ti perfectly fine. Super easy to use but the psu cords are kind of stiff to work with, easily doable just stiff

I've been using this power supply in my pc for over 2 years and I haven't had a single problem with it. I'm running a high power graphics card along with a full PC tower of components. It stays cool enough and I can hardly hear it when its running. I'm pleased with the fact that it hasn't given me any problems at all.

This power supply has been a valuable addition to my PC build. I have had nothing but good performance and zero power or confidence issues, knowing I have this PSU in my PC. I highly recommend it if you need 1000 watts to power your gaming or work rig.

Great reliable power supply with lots of power for upgrades and a silent mode

Clean & easy install. Modular cables, only need install ones you need. Runs quiet and strong. Best 1k you can get.

I upgraded from a 750W gold rated EVGA and I had some doubts about Corsair. After some research, I realized that these are just as good as EVGA. Installing it, I think, was easier since the cables feels more malleable straight out the box. I now have an RX 6900XT and this PSU holds up really well.

It’s a good power supply and I haven’t had an issue with it for couple years now. Although there is one issues that comes and go and that is the coil wine but it’s not consistent and since I put headphones on it doesn’t bother me. It only does it under load.

1000 Watts. What else is there to say? Other than it's also much quieter than my last one. The system just seemed overall happier when I installed it. Most people will probably find it a bit over-powered, but you'll have room for future expansion.

The power supply is well built and was purchased at a reasonable price. It went into a new build and is quiet and included more than enough cables.

Works like a champ, fire and forget. Setup a small server with 2 dscrete GPU's A770 and 2080ti and this unit has not failed or sneezed once. Im splitting the 24 pin and 8 pin CPU pins with 3rd party adapters between 2 GPU adapters as well as using 4x8 Pin GPU ports. Odd setup but works like a champ with this PSU and have plenty of ports/power left.

Easy to hook up and get started. Quiet, provides plenty of power.

Provides stable power for Ryzen 9 7950 and 6900XT. Easy setup and module allow for custom cables.
