  • Multi functional and noise free
Support ATX 3.0 and the running noise is pretty low. I have a Noctua cpu fan, however, the noise from the PSU is even smaller than the cpu fan.

  • Producto de excelente calidad.
Excelente producto, súper silenciosa y el que sea una fuente modular permite una eficiente gestión del espacio sin necesidad de cables extras entorpeciendo el montaje. La coloqué en un gabinete M-ATX quedando muy conforme con el resultado.
