Many appreciate the ease of installation, excellent cable management due to its modular design, and the convenient fan control. The power supply's compatibility with various components is also frequently praised. While some users reported an absence of coil whine, it wasn't a widely discussed issue.

    My son's computer kept crashing. I was advised that this power supply was a good brand. My son has not had an issue since. Price was reasonable, product works great.

    Psu is quality, runs 13700k and a 3090 without issue. Fan is quiet or silent. Oem cables are nice and can have combs added to tidy up looks.

    Honestly this is one of those items that you hope just works and this one does exactly that. The cables are of high quality and just like other corsair products it has a great warranty.
