Molex 4 pin connector2/26/2024 ![]() ![]() * The Molex connector has a lifespan of about 5 years only. Drawbacks associated with the Molex connector * Expensive * May not be widely available * Cumbersome to remove since they do not lock into position using a latch. * They ease repairs since if the connector fails, it can easily be replaced. Benefits of the Molex connector * They make it easier to assemble different components. As computer technology has advanced, so too has the Molex Mini-Fit Jr. This connector can feature twenty or twenty four different pins, depending on the age of the power supply and the motherboard it will connect to. The largest of the Molex connectors on a computer power supply is known as the ATX connector, or the Mini-Fit Jr. One computer can have several Molex connectors. The Molex connectors bring DC power to the drives inside a PC case. The Molex connector is used for power connections for a disk drive in a computer as well as for other computer components such as CD-ROM's, graphic cards etc. The terminal pins on the other hand are what conduct the current. The function of the housing is to hold the terminals and protect them from shorting, dust, dirt, moisture, and electrical interference. The connectors are capable of up to 10 amperes. The connector that provides power has female pins and a male housing while the connector that receives power has male pins and a female housing. COLOR FUNCTION Yellow 12 volts Black Ground Red 5 volts The connector is polarized and designed in a way that makes it difficult to plug it in incorrectly. Recycle older power supplies for repairs or replacements. It connects newer SATA internal hard drives, optical drives, and motherboards to a power supply with legacy LP4, 4-pin Molex connectors. The wires consist of a yellow wire, two black wires and a red wire. The Cable Matters 4-Pin Molex to SATA Power Cable Adapter is a handy addition to your toolbox when building, upgrading or repairing computers. Connectors PCB Connectors & Wire Housings Wire Housings & Plugs 4 Pin Molex Connector. These shells can be arranged to support anywhere from two to fifteen circuits. The pins and the sockets on the ends of a Molex connector are held in place by nylon shells and aligned 5.088 mm apart in a sort of rectangular matrix depending on the application. One piece of the two piece pin and socket design consists of metal pins while the other piece consists of metal sockets. ![]() The connector has a nylon plug and receptacle consisting of a two piece pin and socket connection to which four wires are attached. There are so many cable adapters that power is your only real limitation.The Molex connector has a very simple design. Your PSU only has two SATA plugs, but you can break each SATA plug out to three SATAs with one Molex using something like this for about $4.Īs long as you don't exceed the rated power of your PSU, or of any individual plug (check manual for that), then you'll be fine. But in case you do need four or more, you can just buy a SATA to Molex Adapter for about $2 or $3. I'll give you a high-five if your build needs more than one for your Hue. Rather than trying to figure out if you have enough molex connectors, you can actually challenge yourself to use all three. Use whichever manual goes with your PSU to find out how many Molex connectors.īased on a quick look, it seems like the B3 Series has three (3) molex connectors plus one going to an FDD adapter (for old-school floppy disks), and the Bronze Series appears to have the same setup. B3 Series), and here is the instruction manual for the other (i.e. Here is the instruction manual for one (i.e. EVGA makes only two 450 watt Bronze power supplies. Molex is a legacy plug that most things don't use anymore, but certain components (e.g. ![]()
