    Needed this for larger power components. No issues with installation, or functionality. Being fully modular is great for cable management.

    I have power surplus from Corsair running over 15 years! Very trusted hardware on my side. Downside do not have a power connector for modern GPUs so have to use an adapter provided by GPU manufacture. But for this money, I do not really care.

    Wowza. So. This thing has a point to prove apparently. Please make sure you’re only using the cabling provided by this beast. I made the silly mistake of leaving three cables from previous PSU on the motherboard and the Corsair wouldn’t power on. Swapped out for only the included cabling and voila! Purrs like a happy kitten.

    Needed a power supply, didn't need one this big. But this one has very good reviews and a very long warranty. Got it to be a bit future proof. Maybe a touch expensive for what it is. It's also much larger than a standard ATX power supply, make sure you have room in your case for it. I put it in a Corsair iCUE 220t and I had to take the drive cage out for it to fit.

    Very good power unit. I have been buying Corsair units for so many years. The only complain I have is Corsair could make the cables more flexible and longer.

    Solid PSU for High End GPU

    Came with 3 PCIe cables and was exactly what I expected coming from a RM850x. The 4090 rarely even hits 400W but I also have paired with 13900K so it was worth having an extra 150W of headroom. I recommend it but it was the same price that my 1300 GT+ was from EVGA so not the best bang for buck

    You can have never enough power for your rig. As technology grows, like GPU power consumption, you need more ponies in your rig. Hopefully 1000w is enough to carry me to the make upgrade. It definitely runs quiet when you are running full load and the does not generate that much heat which is surprising. Corsair out did themselves with this line of PSUs.

    Corsair has never failed impress me! I had a unit that was 750W S. Flower. It kept restarting my pc when playing games. I think it was the 10900k RTX 3080 power draw. I put the 1000w unit in and now power to spare. And, for me its future proofing.
