  • Rated 5 out of 5 stars

    Quiet, compact, and super

    This PSU was exactly what I needed for my small form factor build. It’s quiet, runs cool, and has enough power for my high-performance components. The fully modular design made cable management a breeze, and installation was straightforward. Been running it for a couple of months with no issues at all. Would definitely buy again and recommend to others!
