![]() The pin next to 12V is not connected (NC). The ATX power connector breakout does not come pre-assembled. Note: Since this product is a kit, assembly and a basic knowledge of soldering will be required. 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. Depending on the manufacturer of the power supply, the quantity of each connector can vary. One of these connectors is the 4-pin power connector, which is intended to power 12V and 5V computer peripherals (such as disk drives). One suggestion I've learned is that Digi-Key is actually better at pairing up housings and pins, so you can try taking the part number for the housing and searching for it on Digi-Key, and see what they suggest for matching pins.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.ĪTX power supplies usually have a number of power connectors available to power components for a desktop computer. If I do find exact part numbers for matching pins/housings, I'll list them here. I do know from experience that especially the crimp pins don't necessarily always work, because Molex only links a SERIES of pins to each housing, and some times not all pins in a given series actually work with a given housing. *Note that, unless specified, I have not actually tested any of these part numbers (though I do intend to, I just haven't ordered any yet), this is all from searching, so YMMV.

Recently, I started on a project that I wanted to power from a standard PC ATX power supply, which led to me looking for connectors to use so I didn't have to cut up the cable to access the various voltage lines. ![]()
