    Well built, quiet, and just has enough cables for everything. I trust Corsair with their PSUs as I had used their CX650m for 3 years.

    My computer was having issues where everytime i would load into a graphic intense game it was black screen but the computer would still be on. I was so worried it was gojng to be a more expensive part to fix and it eneded up just being the power supply (thank goodness). This power supply is also a lot quiter than the one that came with my prebuilt and my computer has never worked smoother since installing it. Also pretty easy to install. It was my first time swapping that unit so it took about an hour or two just to figure it out. Its so worh it!

    Totally silent for non-gaming activity. The graphics card fans are louder than the fan on this power supply. More than enough cables were supplied for my Intel i7-12700k and graphics card.

    If corsair knows anything besides cases its power supplies. Excellent power supply overkill for some but it helps when you want to add a bigger gpu or have RGB insanity. Super quit no complaints
