Hi k4mil3k ,
Since you’re a developer of PSU, what do you think about the utility/effect for the internet box ?

You mean your main router from your operator in home ? So ... I see that we are entering audiovoodoo themes, so we call them in Poland.
Electronics is my passion, but professionally im involved in IT for 20 years, including maintenance of telecommunications networks. Currently in my work, I also administer a network that works in difficult industrial conditions, there is also a lot of interference from power lines and power supplies for machines with big induction motors with inverters the size of a wardrobe and power exceeding 100kW each... Do you think that im really concerned with powering the router or switches ? Of course, it uses Cat.6 cabling with a additional shield, but mainly because many of the cables run through hazardous ATEX areas and must comply with certain standards. I do not ground the shields.

Internet communication is based on TCP and UDP protocols. These protocols provide control and automatic retransmission of damaged data. Each of the network devices has buffers so as long as there are not many damaged data in the transmission, the user does not even feel it. Personally, I think that changing the power in a router that works correctly makes no sense. I would put more emphasis on avoiding the cheapest cabling and switches. The design of the Ethernet cable, so-called twisted pair, ensures transmission at 100m provided if the standard is maintained. I have already seen patchcord cables that did not have all the wires (only 4 of them are needed for transmission, the remaining 4 provide a shield). So twisted pair cable - if its done correctly, it is very resistant to interference. Also, try to not use the cheapest plastic case switches with tiny wall-plug. There is a lot of metal case desktop swiches that have built in good PSU.

Of course, if you have a small wall plug and you intend to try, you can try cheap Meanwell power supplies in the medical standard. They are really nice for this price.
