    Does what it's supposed to do, have had no issues with it so far! You only have to plug in the cables you need which is great for cable management.

    For those wanting to power high end devices, this is among the list of go to PSUs for builders, it has a heft to it that indicates that it should last a few years of use. The modular cables are very stiff, which can make cable management difficult.

    Corsair PSUs always do well by me. Long lasting, no issues. Only reason I bought this one is to upgrade to a newer GPU, which would require an 850W PSU minimum. The previous 650W replaced uses the same cables, so I did not even have to swap them out.

    Purchased this for a mining rig running 5700X's and Vega's. A great PSU and, from all of my research, the Corsair's are the most reliable and safest. Having the fully modular allows for using only the cables you need, as well as having room for more should you need to. Will continue to use Corsair psu's as I trust their products.

    I really needed a psu that could handle my 4070ti. So i got this and it worked perfectly. It came with enough pcie cables and everything else. I know that the 4070ti doesn’t need that many watts but this was on sale and was around the same price.
