¿QUE FUENTE DE PODER NECESITO, PARA MI TARJETA DE VÍDEO?

¿De cuantos watts reales tiene que ser la fuente de poder de tu computadora según la tarjeta de vídeo? Actualizado a Agosto 2022

Muchas personas no están seguros de cuánto poder requiere como MÍNIMO una tarjeta gráfica moderna ,eh aquí una lista de varios modelos con el tipo de fuente de alimentación que necesitan. Obviamente sería mejor conseguir algo mejor que lo que se muestra. Es sólo una guía aproximada, ya que también depende de los otros componentes de su sistema. Espero que sea de utilidad para todos.


Los siguientes son los requisitos mínimos de energía utilizando una fuente de alimentación con un solo raíl de +12 V. Aplica para sistema que contienen los componentes básicos. Cuanto más añada en tarjetas y discos duros en su sistema, más amperaje debera tener en el carril 12v. para tarjetas que consumen mucha energía siempre recomendamos fuentes de poder certificadas con 80 plus.

¿como saber los amperios de mi fuente?

-Si se tiene 2 rails de +12v se aplica la siguiente formula: 

12V1 Rail + 12V2 Rail - 11% de la suma de ambos raíles = Amperaje 12V. 

Ejemplo:


18 Amperios en el 12V1 Rail + 18 Amperios en el 12V2 Rail - 11% de 36 Amperios = 32 Amperios

 (redondeando el 11% de 3'6A a 4A).

-

-Ahora la lista: ojo estos son los requisitos MÍNIMOS, lo ideal es usar una fuente de 50w o 100w mas para que no este forzada o por si la tarjeta de vídeo es una versión con mucho overclock
