Sometimes labeled on the cable as P7, the Berg connector is a power connection developed by Berg Electronics. It is used with computer power supplies that connect to floppy disk drives, front panel lights, and reset or turbo buttons.
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).
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.
Do floppy drives need power?
Floppy drives use a 4-pin Berg connector for power, which includes +5V, two ground wires, and +12V (pins 1-4, respectively). For just driving the read head stepper motor, the drives only need +5V and ground.
Are all motherboards 24 pin?
Almost all of the new power supplies used today feature a 24-pin power connector to connect to a computer motherboard. However, some motherboards still feature a 20-pin ATX power connection. Thankfully, almost all 24-pin power connectors are designed so that four of the pins can be detached or moved out of the way.
What is a 24 pin ATX cable?
24 pin power cable extends the power connector from a ATX power supply to a motherboard power connection to provide strain relief on the connections of your computer case components.
Why is there a pin missing on my 24 pin connector?
This empty pin on your 24 pin connector used to be home to a wire carrying -5V. Since around 2003 the -5V rail was removed from ATX specification and as a result most modern power supplies do not include it.
What are the power supply connectors?

What is SATA power connector?
The SATA 15-pin power supply connector is one of the standard peripheral power connectors in computers. It’s the standard connector for all SATA-based hard drives and optical drives. SATA power cables protrude from the power supply unit and are meant to reside only inside the computer case.
What is the function of 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.
Which of the ATX connectors 20 pin or 24 pin are used to supply power to the motherboard?
The 24 pin motherboard connector is actually just the 20 pin connector with 4 extra pins added on the end. The original 20 pins were unchanged. The extra 4 pins are not separate rails. They’re just extra lines to provide more current to the same rails.
How do you unplug a 24 pin connector?
The way how I did it is that I push the clip, wriggle the connector from side to side, then pull out the connector. If the connector won’t come out, push the clip and wriggle some more. Make sure you are pushing the clip the whole time.

Power Consumption WD’s 2TB Caviar Green is at 5.2W, and the Seagate Barracuda LP requires 4.2W. Clearly, Samsung did a great job.
How many watts does a 7200rpm HDD use?
The average power requirements for a 2,5″ HDD with 7,200 RPM is ~ 1.75 Watts (read/write), whereas a 5,400 HDD with the same form factor requires ~ 1,70 Watts (read/write).
How much power does a 2TB hard drive use?
The HDD’s average power consumption when operating is 6.8W, and is 5.5W when idle, making it ideal for low-power PCs, data storage appliances, and personal attached storage solutions. 2TB of storage capacity provides plenty of room for media, file backup, and more.
What is GPU power?
Your GPU contains different components that each consume power, and the hungriest is the actual chip. Board power—also known as TGP, TBP, or total power—is a measurement of power supplying the entire graphics card. Chip power—also called GPU or core power—is strictly the power supplying the GPU chip only.
Do all GPU need power?
Well, all computers need a power supply and graphics cards are part of a computer, so in some sense the answer is yes. If however you mean do all graphics cards need additional 6 or 8 pin power cables from the power supply the answer is no. The card can draw about 75 Watts of power from the PCIe card slot.
What is the use of power supply unit?
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
Why do we need power supply?
The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.
Are floppy disks still used?
The floppy disk symbol is still used by software on user-interface elements related to saving files, such as the release of Microsoft Office 2019, even though the physical floppy disks are largely obsolete, making it a skeuomorph.
What voltage is SATA power?
