Sorry if this kind of question has been asked before, but I need a 5V power supply that can provide at least 3A. As I'm still fairly new and the circuit I'm making is a gift for a loved one, I don't want to deal with mains voltage and would get something off the shelf that I know will work good and be safe. As such, I was looking for a traditional wall-adapter type power brick. In my search, however, I realized that I knew almost none of the companies listed after filtering my search criteria, and as such I don't know which ones I can trust. Prices range anywhere from $12 to $80, and I have no idea how much I should pay to get a "good" power supply. If anyone has experience with these companies or can recommend a decent power supply, that advice would be very helpful. Also, I only have looked on Digikey, but if someone can recommend a better place to get power supplies (in a reasonable time) I'd definitely give it a look.
The only company I recognized, which was omitted from the list above, was Adafruit, who has a
10A power supply listed for $32.
