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.

    Worked perfectly as expected from Corsair. I had an 850rx prior and due to parts upgrade i was lacking in power.

    Supposedly one of the best psus that isnt crazy expensive but the one I got abruptly shut off after using for about 30 min and would not come back on. I returned and the new unit seems to be working fine for a couple weeks.

    The 12v GPU single cable is a life savor for new 40 and 50 series GPUs. Its also shorter than my 850 giving more cable managment space. fully sleeved cables. I Highly recommend.

    Installed this in my gaming PC and have plenty of power for my needs and for future upgrades. One of the PCIE cables was faulty and I had to reach out to Corsair to get a replacement.

    After giving other power supplies, a chance amongst a few builds, Corsair has proven themselves to be the most reliable one of all. Don’t even bother looking at another brand.

    It is always nice to future proof a build. Even better when it is discounted to the same as an 850 PSU.
