Review: Power supply is relatively quiet. My unit did not come with an AC power cord.
Review: Recomendada al 100 No decepciona la marca para nada tenía una fuente de 500w de esta misma marca más de 4 años y sigue funcionando por esta razón me incline por esta marca de fuente de poder. Y la pregunta de si hace ruidos los ventiladores para nada es muy silenciosa

### ⭐⭐⭐⭐⭐ Review
*by J***N on 1 January 2026*

This is a great power supply handled my Ryzen 5 7500F and RTX 5070 Ti with a ton fans and aio. Also has the 12v-2x6 ATX 3.1 connector for my GPU which is nice as well. No problems at all the smart zero fan mode is also nice so it doesn't come on at low loads when it doesn't need to. Cables are nice as well and the psu is nice and compact so it was easy to install in my case which is the Montech XR. It is much better compared to my older unit I use to have it will also allow me to get stronger upgrades for PC parts in future if you need to.
