Users also find the cable management to be clean and the installation process easy, with the modular design contributing to a tidy case. A small number of users reported no coil whine.

    Super quiet powerful Corsair psu. I love that it has a connector in the back for modern gpus as well. It’s a game changer.

    I picked it for the cybenetics gold rating, and ability to be efficient across different load levels, as this powers a workhorse/gaming pc, from several HDD in raid, to an RTX 5070, it seems to do the job well! Modular cables bend easily, and it even came with some combs to tidy up some of the wires you'll have to see.

    I had issues with my current power supply having issues after doing some upgrades to my tower. I bough this because of the brand name and warranty and am very happy with how everything is working now the past couple months.

    I was using an 850w PSU with a 4080FE and had power issues. All solved with the 1000x. Highly recommended for higher end gpu.
