    Works with 2014 and 2024 tec

    Make sure to get an unopened box... Works with my Asus X99 MB (2014) and NVIDIA GeForce RTX 4070 Ti Super (2024) gpu. If all of the cables were included I would have kept this in my setup but it was missing 2 runs of sata cables and had 1 extra run of molex. The box was apparently an open box as one end of the plastic was missing but I didn't think anything about that.

    Good budget psu!

    I know it’s bronze but I’ve had this a couple years now & it’s worked great. I’ve used it with a handful of gpu’s and a couple different CPU’s. Worth noting it ran a 4080 and a 9070xt amazingly as well as a 10700k and a 14900k beautifully. No issues highly recommended.
