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.
in addition, What does a Molex plug into?
These “Molex” connectors bring DC power to the drives inside a PC case. The large one on the right is used for disk, CD-ROM and DVD drives, while the small connector is used for floppy drives and other devices.
Also, What type of device would you connect a Molex cable to?
Certain Molex connectors are used for providing power to the motherboard, fans, floppy disk drive, CD/DVD drive, video card, some older hard drive models, and more. Compatible connectors are available from many manufacturers, not just Molex and AMP.
in the same way Should I use Molex to SATA? Safe, yes. Usable, not necessarily. A Molex to SATA connector should be fine for most HDDs and DVD Drives but it may not be sufficient for more modern SSDs and BluRay drives. The SATA power connector includes a 3.3 volt rail as well as the traditional 5 volt and 12 volt rails.
Where do you connect Molex?
the molex connectors are to connect the fans directly to the PSU. The female part of the Fan-Molex-Connector to the male connector of the PSU. The male part of the fan is just so you don’t lose a connector by using the fan and can connect to any other molex female connector in your setup to supply power.

What is the purpose of the 4 pin Molex connector?
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.
Can I convert Molex to SATA?
Another option is to use a molex to SATA adapter cable. By going this route, you won’t need to worry about swapping out your power supply. Instead, all you need to do is plug the adapter into your PSU. Then plug your hard drive into the other end, and you’re good to go.
Is Molex to SATA safe for fans?
Perfectly safe. You are powering fans. They only need the two lines you are giving them.
Can I plug Molex into SATA?
SATA Power Shortage Solution
The Cable Matters 4-Pin Molex to SATA Power Cable Adapter is a handy addition to your toolbox when building, upgrading or repairing computers. It connects newer SATA internal hard drives, optical drives, and motherboards to a power supply with legacy LP4, 4-pin Molex connectors.
Does molex plug into motherboard?
The 4 pin molex power connector on motherboards is found near the PCIe 16X slot is used for additional power for the video card in that slot. The manual explains it is there for modern, high power consuming cards, which do not have their own power connector on the card.
Why is Molex hated?
Cons: It’s bulky and when manufactures make them cheaply, they don’t align properly and you have to wiggle both sides around for a few minutes to connect them. It only provides 5v and 12v power while SATA provides 3.3v, 5v, and 12v. Pros: The connector is much easier to de-pin than SATA.
Do people still use Molex?
Basically since around 2006 IDE and their molex powered devices are zero. And everything now is now SATA power. Motherboards have no IDE connectors on them no more, and any DVD drives and hard drives you buy all come with SATA power connectors and no more Molex support.
What replaced Molex?
During the 90s, the Molex compound was phased out in connector housings, replaced by other thermoset plastic material, and eventually more environmentally friendly, recyclable thermoplastic materials.
Is Molex 5V or 12V?
All the other plugs coming out of the power supply—called Molex connectors—are for drives, and they provide +12V (yellow) and +5V (red) power, as well as two ground wires (black).
What is a PATA connector?
Parallel ATA (Parallel Advanced Technology Attachment or PATA) is a standard for connecting hard drives into computer systems. As its name implies, PATA is based on parallel signaling technology, unlike serial ATA (SATA) devices that use serial signaling technology. … The cable for a SATA connection has seven conductors.
Can 3 pin fans plug into 4 pin?
1 Answer. Apparently a 3-pin fan can plug directly into a 4-pin socket. Two of the pins provide power to the fan, the 3rd provides an RPM pulse to the motherboard to read the speed. The 4th pin is for PWM speed control.
What is the function of 4 pin Molex P4 12V?
This Motherboard P4 12V 4-Pin to Molex 4-Pin Power Adapter Cable is used when you want to upgrade your system to a Pentium 4 (P4) system. Using this cable allows you to upgrade without having to buy a new power supply.
What connector has 4 pins is used for older IDE drives?
a 4-pin connector used for older IDE (PATA or Parallel ATA) drives and some newer SATA drives, providing +5 v or +12 v to the drive.
Which is better Molex or SATA?
Technically Molex can carry much more power than the SATA power connector. Molex has 2 power pins (one 5V and on 12V pin), each can deliver 11Amps for a total of 22Amps. The other 2 pins are ground wires… SATA power connectors has a total of 15 pins of which 9 are power pins (3 x 3.3V, 3 x 5V, 3 x 12V).
Do SSD need 3.3 V?
One problem we have with testing mSATA SSDs is the fact that they require an mSATA to 2.5″ adapter with a voltage regulator since 2.5″ SATA is 5V whereas mSATA spec is rated at 3.3V.
Does Molex transfer data?
Distinguished. PATA and SATA cables are used to transfer Data from one device to another Molex and SATA Power cables provide energy for a device to work. They can be connected to any number and types of devices inside your system.
