    Psu is has a very nice look, good length cables, and quiet while idle/load. I took one star away because the rubber on the cables are very soft so you have to make sure you don’t scrape them against any hard edges inside the case. They will scratch fairly easily but some custom wires later one could be a better alternative.

    I realized just after purchasing a 4080 Super that i needed a new power supply. I felt like it would be super hard or confusing but this modular power supply was really easy to use and the 850W is more than enough to power everything. This thing also comes with plenty of cables and everything i needed to convert from a 5 year old power supply to a new modular setup.
