What is a 4-pin Molex connector used for?
What is a 4-pin Molex connector used for?
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 Molex connectors bring DC power to the drives inside a PC case.
What is the use of 4-pin Molex 4p 12v?
The ATX 4-pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.
Are Molex cables still used?
Molex is a legacy plug that most things don’t use anymore, but certain components (e.g. coolers and lighting) still use it. EVGA makes only two 450 watt Bronze power supplies.
Do I need a Molex cable?
Molex connectors are necessary when you don’t have any 3 pin headers left on your board to connect fans. Then you use molex connectors to connect the fans to your power supply rather than the motherboard.
What do Molex cables do?
How many watts can Molex handle?
54 watts
The ATX standard for SATA or Molex connections is rated for 54 watts. Each SATA/Molex connector provides three 12v pins at 1.5 amps each, for a total of 4.5 amps. 12 volts, times 4.5 amps, equals 54 watts able to be provided by a SATA/Molex connector. Some PCIe risers do not conform to ATX specifications.
Is Molex peripheral cable?
The Molex 4-pin power supply connector is one of the standard peripheral power connectors in computers today. This power connector is the standard connector for all PATA based hard drives, many high-end video cards, and some older optical drives and other internal devices.
What is the purpose of the 4 pin Molex connector?
The standard “Molex” 4-pin connector is a power connector used in computers to power peripheral data drives. It has a 5V and 12V power supply, and ground wires for each. For modern computers, SATA is the common protocol, and most new drives use a SATA power connector, so the Molex connector is becoming obsolete.
What is a 4 pin peripheral connector?
Peripheral Power Cable (4 Pin) A peripheral power cable is used to connect the older IDE hard drives and cd/dvd drives to the power supply. There are four cables (1 yellow, 2 black and 1 red). Sometimes there are eight cables, this happens when there is another cable coming out of it to connect to another hard drive or cd drive.
What is a 4 pin CPU power connector?
The ATX 4 pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.
What is the name for the 4 pin fan connectors?
A four pin connector is a little different than the three pin connector since it has the extra (fourth) wire used for controlling and sending signals to the fan, which likely has a chip on it that tells it to slow down or speed up (in addition to the other wires the three pin connector has). Three Wire and Four Wire Fan Connectors
