What is P4 12V connector?

What is P4 12V connector?

The P4 connector is a 12V power supply cable used with motherboards that have an Intel Pentium 4 or later processor. Today, the connector is a standard power connector and is used with both Intel and AMD motherboards.

What is 4 4 pin ATX 12V power connector?

ATX 4-pin 12V Power Connector Pinout 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 ATX 12V power supply?

An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version.

What is the 4 pin power connector for on motherboard?

As the motherboard specification says, it’s a 4-pin ATX 12V power connection. Pretty much every modern motherboard has a separate 12V power connector that’s either a 4-pin or an 8-pin. The primary purpose of this power connector is to power the VRM that supplies power to the CPU.

What is the difference between ATX and ATX 12V?

Another difference between ATX and ATX12V is the power efficiency rating, which determines how much power is pulled from the wall compared to the output of the computer. Some older ATX PSUs have an efficiency rating below 70 percent, while the ATX12V standard requires a minimum rating of 80 percent.

Is the 4 pin necessary?

This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it.

Will ATX 12V work on ATX?

So no, you don’t need a ATX supply, a 4 pin 12V supply will work fine as long as it supplies enough power (144 watts).

Do you need both 8 pin and 4 pin CPU power?

You do not have to plug that extra 4 pin CPU power connector on the board. The 8 pin is more than enough for running the system. You’re totally fine without it. If you’re upgrading to a RTX 3070 or 3080 and a Ryzen 5600X your 650 Watts should be enough since it’s a good model.

What is the function of an ATX power connector?

– While charging AC is converted to DC and stores in battery (converter) . Because only dc can be stored easily in form of battery. – Storing in battery in form of DC – Then while driving or acceleration Dc gets converted to back to AC (inverter) to run the motor depending on commanded rpm.

How do I manually turn on an ATX power supply?


  • Solder Wick
  • Soldering Iron
  • Needle nose pliers
  • How to convert an ATX to at power supply?

    Since the ATX power supply works with high voltage,take care that it is unplugged and also wait some time before take it apart!

  • Also take care during soldering that you don’t make a short circuit.
  • Make sure that you didn’t forget to connect the protective earth cable (green-yellow) back to its position.
  • What is a 20 pin ATX power connector?

    Most power is now provided on 12 V rails.

  • The power on 3.3 V and 5 V rails was significantly reduced.
  • The ATX motherboard connector was extended to 24 pins.
  • The six-pin AUX connector from ATX12V 1.x was removed because the extra 3.3 V and 5 V circuits which it provided are now incorporated in the 24-pin ATX motherboard connector.
