    This PSU made is easier for me with the wiring, especially with its dedicated 16vhpwr cable and port. This made sure I used less wires and kept cable management tidy.

    Corsair has never let me down. My last 650W that I bought in 2016 is still going in my previous build, but it was time for a new build. The new 12+4-pin connector for modern GPUs is very convenient and helps keep cable management clean.
