    Excelente producto

    Excelente producto, no podía usar mi RTX 4070 TI Super, ya que se pagaba sola de forma inusual, pero está fuerte tiene el cable adecuado para soportar las cargas de trabajo intensas. Muy satisfecho con la compra. La recomiendo.

    Disappointed power supply

    I bought this because of the brand's reputation, but it let me down. The quality isn’t as good as described. Right after unboxing, the packaging felt cheap. The material of the power supply itself is poor, and the cables are stiff,I’ll be returning it.
