Do you need to power a project with 12V and 5V from one power supply? The ATX power connector breaks out the standard 4-pin computer peripheral port for your 12V and 5V devices! Once you have chosen a power supply (whether it be an ATX power supply or the included 12V/5V wall adapter), you're ready to give your project some life! This kit has everything you need to solder together an ATX breakout and screw terminals for powering your project directly or pumping power into a breadboard.
ATX power supplies usually have a number of power connectors available to power components for a desktop computer. One of these connectors is the 4-pin power connector, which is intended to power 12V and 5V computer peripherals (such as disk drives). Depending on the manufacturer of the power supply, the quantity of each connector can vary. If you want to easily grab some juice for your project from this connector, you'll need to connect the breakout board to this port.
Note: Since this product is a kit, assembly and a basic knowledge of soldering will be required. The ATX power connector breakout does not come pre-assembled. Only the pin next to 5V is grounded. The pin next to 12V is not connected (NC). Please refer to the picture of the bottom of the unit for more information. The AC cable for this is included and works with 100-240VAC inputs via a 2-prong style plug.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I haven't had a chance to really put this through its paces yet. But it is a perfect fit for the project I purchased it for. I needed exactly 5V and 12V for my project. I won't need the full 2A on the 5V rail. But 2A on the 12V rail will be handy as I am driving a group of solenoids that pull .25A each.
JUST TO LET YOU KNOW ,EVERYTHING IS WORKING OUT OK. VERY GREAT KIT LIKE IT VERY MUCH. I DID GIVE THIS INFO TO ANOTHER HAM, FOR HIS PROJECT.
It fixed a 40 yr old Phillips G7400(Odyssey3) Gaming console, the new power supply gave new life to the console!.. easy to put together!.. will buy again
The 5V and 12V from the power supply are swapped from what is labeled. The output next to the ground is producing 12V and the isolated output is producing 5V. I just cooked a project with 12V that was drawn from the labeled 5V side of the ATX connector. I know I should have checked, but I did not.
We had an issue with these back in May 2020.
