    Its quite and it runs well but it doesnt connect to my mother board very well if you bump the computer a certain way the whole thing turns off

    Best PSU i have used PERIOD Supplies your rig with efficient power, fully modular so you dont have a clutter (not sure if thats the right word but you get the idea) of cables around making your build ugly or difficult to cable manage.

    You will need to use both 24 pin and the CPU 8 pin for this to work.

    Easy to install. Looks great in an all white build. Quiet. Solid psu with more than enough cables for your GPU and hard drive needs.

    1st one DOA, second one sent from Corsair was a certified refurbished which works but fan is noisy. Wont be buying another Corsair PSU anytime soon. Sticking with Seasonic and EVGA from now on

    Great

    Bizarre design choice not to include any straight SATA power connectors makes it impossible to use with any flush-mounted SSD; every provided SATA connector is bent at a 90-degree angle.

    I really haven’t had any problems expect that it can be a lot louder than I’d want. But I can’t really complain when I’m the one stressing the PC

    Probably the easiest and most enjoyable time Ive had building a complex loaded PC - cables are great quality and length, super super quiet.
