    Brought for my Ryzen 7 5800x3D upgrade and powers that, the system board and a RTX 3060 just fine with no issues. Very quiet, cant hear anything even in a case full of noctua fans, they make more noise than the PSU

    Easy to install with connectors that met most of the PC build's needs. The PSU was recommended from a PC building site PCPartPicker, two issues were that the PSU did not provide a 4-pin power connector which meant it could not supply to the 3rd slot on the ASUS GameTUF Z590 MB and the CPU 8 Pin Connector shape was different from the the board's 2nd slot though it was still possible to insert.

    The packaging was wonderful. I love the sleeved cables included with this unit. So far it is working well! The fans typically never cut on under the load I put the computer under and if they do, I never hear them.

    When the old one when the way of the dodo, we went with this one to replace it since it was what we could find quick. The fact it's totally modular makes it a breeze to install, but the only downside is that you HAVE to use the cables it comes with. if you attempt to use any of your old cables it will not boot up the computer at all if you're lucky and will likely cause more damage if you're not.

    During normal usage, my rig is fully silent. I think I can only really hear this thing when I am gaming. When I first purchased, I had a problem with it revving that seems to have fixed itself.

    I replaced a faulty non-modular power supply with this modular supply, which really cleaned up the interior of my case since I only installed needed cables. Also, it’s variable speed fan is very quiet.

    This PSU is among the best you can get quality and feature wise. I like that being fully modular, you connect only what you need. Looking inside the grill you can see the quality components in there. Very happy with this PSU.

    It works really well, may not be very quiet but expect a reliable Battery supply for a good pc. It came with a lot of spare pieces and zipties for clean replacement and cool temps.

    Great power supply for my custom built PC running a RTX Ventus x2 3070. Lots of cables for any PC needs and it fits my case snuggly. A little more than I had planned on spending but I'm happy overall.

    A superior product to the Gigabyte Power Supply that came shipped with my gaming PC. Corsair has always been a trusted name in Power Supplies, you can not go wrong with this one.

    I returned this because I thought it was something wrong with my old power supply. I wish I would've kept it though. It looks so neat and has way more power than I probably need.
