Pico psu

Hi,
I would like to buy this kind of power supply for my desktop sff pc (to replace the sfx power supply ) which would power 1 micro atx board, 1 53watts tdp processor and 1 ssd. I would like to have your opinion about this type of power supply? is it reliable ? it can last longer, i mean, as long as a conventional power supply?
Thanks.
I use to watch the videos on you tube of Mr. Carey Holzman who recommended your site.

 

What is the make and model number of the desktop sff pc?

What is the make and model number of the current sfx PSU?

 

My desktop Pc was built by myself. It is a little bit old, 1 motherboard micro-atx from Msi chipset h81, 1 processor from intel G3258 4th generation, 1 ssd 120gb from Toshiba and 1 Dvd/Rw drive.
