![]() ![]() 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. 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. When processors began to require more power, the ATX Version 2.1 specifications added a 4-pin motherboard auxiliary. ![]() *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.

ATX 24-Pin 12V Power Connector Pinout (ATX v2. The connector itself is a Molex 39-01-2240 connector, often called a Molex Mini-fit Jr. For now, I'm mostly looking for part numbers by Molex, but if anyone finds them from other manufacturers, I'll take those as well.ĪTX 20 pin standard motherboard main power connectorĤ-pin motherboard supplemental power connector The ATX 24-pin power supply connector is the standard motherboard power connector in computers today. This list is a work in progress, so please feel free to add to it. He has no plans to overclock the spare build, and he's using a relatively lower end video card. Yes, I know that Sparkfun carries a few of these connectors, but I still like having MPN's rather than relying on a single distributor, so I figured I'd document my findings here. An 8 pin cable will fit, but only in one orientation, would it matter which set of 4 pins is used P phill Moderator Staff member Joined Messages 14,561 (3. Does it have to be used, I dont have a single 4 pin cable, only the 8 pin style. 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. Socket connectors are designed for use with flat ribbon cable, and are generally used to transfer data among devices. 1 The new mobo I bought, Asus Crosshair VII, has an additional 4 pin CPU power connector. ![]()
