    Customers say

    Customers like the noise, quality and performance of the power supply. For example, they mention it's very quiet, well constructed and runs great. That said, some appreciate the size and say it fits perfectly in amazingly compact spaces. That being said, they do complain about the cables being a little short.

    Reviewed in Mexico on January 15, 2019
    No se como lo han logrado, pero Corsair se ha sacado un 10 con esta fuente: es diminuta, silenciosa y muy eficiente.

    El ventilador ni siquiera se enciende si el sistema no se está usando de manera demandante, característica que la hace en extremo silenciosa y en caso de encenderse, no hace mucho ruido el ventilador. Es una fuente de poder, así que no puedo agregar mucho más, pero si les puedo decir que si están buscando una fuente SFX de gran calidad, este producto es excelente.
