## Description

Warning 1, This board is suitable for electronics enthusiast over 13 years old, and minors need to use it under the guidance of adults. 2, It is compatible with 20/24pin ATX power supplies. Different ATX power supplies may provide different maximum currents. 3, It does not have an insulating shell, so please be sure to pay attention to short-circuit when using it. 4, It may produce electric sparks when it is accidentally short-circuited. Please keep away from flammable and explosive materials such as alcohol when using this board. 5, In the case of a short circuit, the ATX short circuit protection may cut off the circuit before the fuse, and it is not that the fuse of the board is bad. 6, When the fuse is blown, the indicator light will go out and the output ports will not provide output voltage. 7, It may generate a lot of heat when connected to a high-current device. Please pay attention to ventilation and heat dissipation, and take care to avoid burns. 8, When connecting high-current equipment, please pay attention to the use of appropriate wires, too thin wires will produce high temperatures. Fuse At room temperature of 25±5 degrees Celsius. 1, When the current reaches the rated current, the blowing time is at least 4 hours. 2, When the current reaches twice the rated current, the blowing time is up to 120 seconds. 3, When the current reaches 10 times the rated current, the blowing time is at least 10 milliseconds. Recommended oxygen-free copper wire and maximum current 26AWG~1.5A/25AWG~2A/24AWG~3A/23AWG~4A/22AWG~5A/21AWG~6A/20AWG~8A

Review: Board works as intended, offers accurate voltages, and is incredibly easy to set up.
Review: This board works fine and came with extra fuses, which is nice. The only complaint is similar to what others mentioned, the soldering is sloppy. Even some solder spatter still on the board. While I like it, I may choose another option in the future.

### ⭐⭐⭐⭐⭐ Review
*by M***G on 29 December 2023*

It works great for what it is and the quality is very good. I have a nice Power Supply from an old PC and didn't want to throw it away so I got one of these and I am happy I did. Gives you good stable voltage varieties. I printed a very quick and crude case for it and its perfect for my needs.
