★★★★★cable layout makes zero sense for a 750 watt power supply
This power supply has only one 8pin connector and one 12 pin high power connector which makes it useless for all most all video cards on the market that requires a 750 watt power supply. It is also so lightweight that it really makes me question the build quality. I would stay away from this thing.

★★★★★Buena fuente equilibrada y silenciosa por su potencia
La ASRock PRO-750B me ha dado muy buenas sensaciones. Con 750 W y certificación 80+ Bronze, entrega energía estable y sin ruidos molestos, incluso con cargas moderadas. El ventilador es silencioso y la instalación fue sencilla.

★★★★★Does not work with the ASRock 7700 graphics card
I'm pretty sure this could be a solid power supply but they recommended that should be ordered with the ASRock 7700 graphics card. You have 2 different PCIe connections, 1 which isn't compatible. I recommended checking the specs before ordering.

★★★★★Buen producto
El cableado no es enmallado como mi anterior fuente... Pero cumple con su funcion

★★★★★Es un poco mas de lo que esperaba
Funciona perfecto, le doy 4 estrellas porque los cables son demasiado enclenques, pero ha servido para jugar con una RTX 5060 y para alimentar los demas componentes, es silenciosa la fuente, la recomiendo si buscas una opcion buena y economica
