Good power supply for computers and accessories

I have used several Meanwell power supplies over the years and have always had good luck. They're well made, designed for industrial and commercial use, and come with features like short circuit and over-voltage protection not found in some cheaper power supplies, and an adjustable output voltage (+-10%).

Pros
  • Nice packaging
Cons
  • Expensive insurance

Is it legal UL listed and 3 amps for $17?

is UL Listed for DIN Rail and 3.33A and UL Listed (I checked the listing number, it's genuine). The performance is clean enough to easily run a Bluetooth device. Keep the price at $17!

Pros
  • Everything is fine!
Cons
  • Longtime

Works great perfect for compact wiring

I have this power supply to power my NUC computer in my custom CNC control box and it works great and really helped me with the wiring for to clean up the box (instead of having a standard connector for connecting to a computer).

Pros
  • Great design
Cons
  • Can't remember
