Can I use a 20 pin PSU on a 24 pin motherboard?
Can I use a 20 pin PSU on a 24 pin motherboard?
CONNECTING A 20-PIN PSU TO A 24-PIN BOARD. Technically, a 20-pin ATX connector can be plugged straight into a 24-pin motherboard socket, leaving male pins 11, 12, 23, and 24 unconnected. The power connector is polarized, so it’s difficult to insert it wrong into the header unless you force it really hard.
How do you plug a 20 pin into a 24 pin?
“… you can plug a 20 pin cable into a 24 pin motherboard and it will work just fine. At least, it will for a while. They added those extra 4 pins for a reason. When you plug a 20 pin cable into a 24 pin connector you’re not providing the extra current carrying capacity which may be needed by the motherboard.
Is a type of motherboard that has a 20 or 24 pin power connector?
ATX 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 function of a 20 pin or 24 pin slotted connector?
It is one of the largest connectors inside a computer. It connects a power supply to an ATX style motherboard. As shown in the picture, the 20-pin cable is a multi-color cable and may be labeled as P1. With the introduction of ATX-2, this cable is now a 24-pin cable and no longer a 20-pin cable.
How do you take the 24 pin off the mother board?
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.
Are all 24 pin cables the same?
Disclaimer: The only difference between Type 3 and Type 4 cables is the pinout of the 24-pin ATX cable; all other cables (SATA, PCIe, etc) are the same.
How many pins does the ATX12V 2.x power supply have?
Current version of ATX12V 2.x power supply provides two connectors for the motherboard: a 4-pin auxiliary connector providing additional power to the CPU, and a main 24-pin ATX 2 power supply connector, an extension of the original 20-pin version. Power Supply On (active low).
Why are I so scared of the eatxpwr?
The reason I am so scared is that the Power Supply cable that has the 20-pin EATXPWR and the adjacent 4-pin EATXPWR connector has a warning label attached to the 4-pin. It says “WARNING! Do not connect this wire with the 4-pin 12V ATXPWR. Doing so will damage the CPU and Motherboard.
Is the 4 pin the same as the 20 pin?
The warning is just telling you that the 4 pin that goes with the 20 pin is NOT the same as the 4 pin that goes in the CPU power connector. The 4 pin that says that should go with the 20 pin to make the full 24 pin motherboard main power connector, while the other 4+4 pin should connect to the CPU power socket.
How do you short a power supply pin?
Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. /PS_ON activated by pressing and releasing the power button while the power supply is in standby mode. Shorting the pin 14 (/PS_ON) to GND (COM) causes power supply to switch ON.
