    Modular

    Cords aren't great but battery works no issues

    Battery works great and I love that it's modular. The only thing I wasn't a fan of was the cords that came in it. They're super stiff and kind of hard to work with. I felt like I was going to break something when trying to get things plugged in and the cords out of the way. I'd definitely either eventually upgrade those or just have better ones ready when you get this.

    Has for about 8 months now with no issues. Very quiet power supply and like all Corsair products works as well or better than most. Being modular really helps reduce the case clutter and improve airfolw.

    Good power supply and got it slightly discounted. Cables were a little stiff and hard to move. However, this is expected with a brand new product and didn't hinder the installation process.

    Had an older 750 watt Corsair PSU that gave me no issues until it died after 2.5 years. Probably should've looked into the warranty but it was easier to pick this up and will prep my rig for a future GPU upgrade. Worked flawlessly after install.

    I needed an upgraded PSU to handle my new GPU and this Corsair was just the right product to purchase. The reviews were good and I was between this one and a similar priced EVGA. Ended up pulling the trigger on this one.

    Reasonably priced. No issues so far. My only complaint are the cables, the shrink wrap holding the braid to the cables makes it hard to route.
