650w Made in Japan parts = Premium
Absolutely amazing solid power output and performance I replaced my bad evega PSU with this one u get more than what I pay for very premium when I say made in Japan parts ect it's a must have at that with all the different electric protections it offers and easy set up /install it's perfect for a full ATX build plenty of room and cable length

Good Quality and Decent Cabling for Modern Systems
Smooth and quiet. Black cabling is nice and allows it to blend into the system better. Would prefer it came with additional SATA support out of the box (without needing adapters) for those of us running optical drives. High quality capacitors are a huge plus.

Great for relatively cheap psu
Works as it should and is incredibly quiet, powers my 450w rated build without breaking a sweat, and dont let the 80+ bronze scare you as this thing is actually quite stable

It meets the specifications
It is still too early to say but for now the product works very well and feels of good quality and makes no noise I will see if it lasts as promised but so far I confirm that it is an excellent product

The fan needs to face down to fit your case
Make sure your power supply's fan faces down, originally i thought I bought a wrong piece because I couldn't make it fit, but the realization hit that I was just wrong.

¿ Recomendaría esta fuente de alimentación ? sin duda alguna
Hace poco me llego esta fuente de alimentación y lo único negativo que podría decir de esta, es que en la caja no viene incluido algo que haga de puente para probar la fuente de alimentación sin necesidad de instalarla en el pc, Pero con las cosas buenas tengo mucho para decir como el diseño Diseño y construcción: El diseño semi-modular facilita la gestión de cables, lo que es una gran ventaja para mantener el interior del gabinete ordenado y optimizado para la ventilación. La calidad de los materiales se siente sólida, sin puntos débiles obvios. Rendimiento: Con certificación 80Plus Bronze, es eficiente en términos de consumo energético, lo que se nota en la reducción del calor generado. He notado una buena estabilidad bajo carga moderada y alta, especialmente con una tarjeta gráfica de última generación que aprovecha el PCIE 5.0. También cuenta con compatibilidad con ATX 3.0, lo que la hace una opción futura con soporte para los estándares más recientes. Ruido: En términos de ruido, el ventilador es silencioso incluso cuando la fuente está bajo carga, algo que valoro en una fuente de alimentación, ya que prefiero un entorno de trabajo tranquilo. Conclusión: Recomiendo la Thermaltake Smart BM3 650W para quienes buscan una fuente confiable con buen rendimiento energético y compatibilidad con hardware de última generación. Es una opción sólida para equipos de gama media y alta, con un equilibrio adecuado entre precio y prestaciones.

Good PSU
Works as intended. Running a Ryzen 7 5700g and a RTX 3060Ti with no problems under high load.

it’s great
only had it in a few days but so far it’s super awesome. it’s a good price and modular so it worked awesome with my mini atx build with a small case. Only thing is that I wish it came with extra sata power cables.
