Nice fit for my build.
This was a good choice for my build. I used an ASUS BTF motherboard and the cables and BTF orientation of this power supply worked great. All the cables are hidden behind my motherboard and the case looks incredibly clean. The noise level is low, I don't really hear it at all, and certainly not when my fans are running.

Excelente Fuente
Disminuyó el sonido de Coil Whine de mi Grafica, es silenciosa y cumple con lo acordado. El manejo de cables depende de tu case, si piensas poner está fuente en un gabinete como Hyte Y60/Y70 olvídalo, si cabe y todo, Pero los cables saldrán por arriba y los vas a tener que aplastar y hacer un pequeño corte en el gabinete para que puedan pasar. La recomiendo? Sip, Por mucho, si tú gráfica solo ocupa 2 cables PCIe de 8 pines, Pero si ocupa 3, busca otra, tiene la capacidad, Pero solo tiene 2 cables incluidos. La use con una 7800xt de Sapphire.

Good
I really like that it came with good quality power cables. It is a superior product. The modular design will make it easy to fit any rig or PC case.

Buena fuente para PCs gama media
Gran rendimiento, silenciosa y suficientes puertos para gráficas qué requieren 3 conectores aunque no recomendable si se van a usar extensiones ya qué el manejo de cables puede ser un poco complicado dependiendo del case
