    Great PSU but cables too thick for mid sized tower

    This PSU is great if you have a massive case. My NZXT H7 Flow, unfortunately, proved to be too small to properly fit the PSU in also the extremely thick cables. I somehow managed to squeeze the PSU in but there was no way I could cable manage such massive cables in such a constrained space so I just let them be.

    I knew that I would need a 1000W unit with all the new CPU and higher end GPU power requirements. I considered this to be the most trusted and competitively priced PSU.
