    Super quiet cooling fan, all cables come with it, works really well. Nothing bad to say except a touch pricy.

    I purchased this power supply for my build to have a lot of room for upgrading down the line. Even though my first one popped and stopped working, Corsair’s warranty allowed me to get it replaced with no charge but shipping and the designof the unit helped contain the spark savind the rest of the computer components.

    Excellent power supply if you can snag it at 130-140. Power delivery is reliable and performs great in a system with 7950x3D and 7900XT.

    Running an I7 13700k and RTX 4080. Would give it 5 starts if the cables were a bit cleaner. Power supply runs quite, and have no issues.

    Purchased this to replace a 800-watt PSU with coil whine and to offer a higher power ceiling for my PC components. It was a bit of a pain to install in a mid-tower case due to the thick cables, but so far so good.

    Only reason I didn't put 5 stars is because it is bigger than a standard PSU. Listen to other customers when they say this in the comments, don't make the mistake I made and didn't listen.

    Does the job. Good for a 3090 card... if you can get one. Room for error if you're running dual gpus.

    The Apevia that came in my computer died (and took something else out, probably the motherboard) and I had best buy swap this in the replacement computer from day 1. Its much quieter and the modular setup means theres no rats nest in the machine.
