    A great option for mining since you can run about 800W of GPU's in a single rig on a single PS.

    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.

    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.

    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.
