What is the Molex connector on a motherboard for?

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.

How do I identify a Molex connector?

The Molex connector is one where the male/female terminology is a bit odd. The female connector is usually found on the end of a cable, and it slips inside of a plastic shell which surrounds the male pins on the male connector.

What is Molex TPA?

Molex Micro-Fit Terminal Position Assurance (TPA) Connectors are available in multiple circuit sizes and cable lengths for power applications. These connectors offer 3mm pitch, up to 8.5A maximum current rating, many design options like terminal position assurance, blind-mating, and compliant pin features.

Is Molex 5V or 12V?

Integrated serial ports on older systems use +12V; while on newer systems, they use +3.3V or +5V. 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).

Do I need a Molex connector?

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.

Can I use Molex to power HDD?

Regarding your original question though, if the psu has 4pin molex plugs it’s fine to use. The hdd can use either.

How many watts does a Molex connector have?

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.

Is SATA and Molex the same?

When you’re installing a new SSD or HDD drive, there are two primary types of connection: molex and SATA. Molex connections have four large pins, which are shaped similar to the ground prong on an AC cord. SATA connections, on the other hand, have a flat, 15-pin design that looks much more advanced.

What voltage is Molex?

Molex power comes from the 12v rail. The LED strip will probably be a little dimmer than usual with 9v.

What does SC and LC stand for?

At the same time, the demand for fiber-optic connectivity devices such as the Subscriber Connector (SC) and Lucent Connector (LC) is escalating due to a massive growth in high-bandwidth communication and data services.

How many SATA can Molex power?

With a simple molex connection, you can attach up to 4 SATA devices. That’s enough for an SSD, an HDD, and a Blu-Ray drive, with an extra plug left over for later expansion.

How many amps can Molex?

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.

What happens if you plug A 12V into A 9V?

Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. There are some guitar pedals built to handle voltages higher than 9V. Those pedals will work perfectly fine with a 12V adapter.

Can I plug 9V into 5V?

In general, connecting a 9V supply to 5V device could damage it immediately, or in long term, but it is impossible to say without seeing the schematics of the device how much excess voltage it can handle.

Why is Molex better than 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).

Why choose Molex SMP subminiature connectors?

With superior frequency performance from DC to 65 GHz, the SMPM connector also compensates for the axial and radial misalignment issues inherent with board-to-board mating. Molex SMP subminiature connectors offer excellent performance from DC to 40 GHz.

Does Molex make wire-to-wire connectors?

Molex has a variety of wire-to-board connectors that offer a wide range of solutions for high-power or microminiature applications. Find the wire-to-wire connector that best fits your application needs. Molex has a variety of wire-to-wire connectors that offer a wide range of versatile power and sealed solutions.

What is an SMT potting connector?

Available in 1.50 and 2.00mm pitch sizes, this W-to-B connector system is the fist SMT type potting connector in the market. Provides an integrated ISL to ensure proper terminal insertion and prevent accidental back-outs to achieve a secure electrical contact and improved mating retention in high-vibration applications

Why Molex SMPM RF blind-mate?

Today’s electronics are smaller than ever, often facing more vibrations and greater stress. Molex SMPM RF Blind-Mate board-to-board and cable connections can minimize your PCB footprint for even the smallest, smartest devices.
