Consequently, what is the purpose of the 4 pin Molex connector?

Power Supply Connectors These "Molex" connectors bring DC powertothe drives inside a PC case. The large one on the right is usedfordisk, CD-ROM and DVD drives, while the small connectorisused for floppy drives and other devices.

Furthermore, what is the purpose of ATX power connector? ATX power connectors are designed to connectacomputer's power supply to an ATX motherboard.Theyare constructed of metal pins laid throughout a nylon matrix.Afemale type ATX power connector extends from theATXpower supply to plug into the motherboard.

Beside above, what does the 4 pin connector on a motherboard do?

Pretty much every modern motherboard hasaseparate 12V power connector that's eithera4-pin or an 8-pin. The primary purpose ofthispower connector is to power the VRM that supplies powertothe CPU.

What is the purpose of a post diagnostic card?

Can a 3 pin fan plug into 4 pin?

Apparently a 3-pin fan can plugdirectlyinto a 4-pin socket. Two of thepinsprovide power to the fan, the 3rd provides an RPMpulse tothe motherboard to read the speed. The 4th pin isfor PWMspeed control. If you plug a 4 pin fan into a3pin socket, the fan speed will be controlledbyvoltage and it'll still work.

How many watts does a Molex connector have?

You can combine 2 molex connectors into a 6pinpci-e connector that will provide 72 watts(thesewhere supplied in the box with my evga vid cards). Itwouldbe a bad idea to use a 6 pin to 8 pin aftermarketconnectorbecause it would mean that you aresupplying 75watts where you are supposed to supply150watts.

Will a 4 pin CPU connector work in a 8 pin socket?

The answer is yes. A 4-pin can be put,byitself, into an 8-pin CPU power socket andthemachine boot up and run. It will give it what poweritcan, and if the CPU draws more than that,itwill shut the system down. If it shuts down when youstartdoing intensive stuff, just underclock theCPU.

What is the CPU power connector?

CPU Power Connectors. Power fortheprocessor comes from a device called the voltage regulatormodule(VRM), which is built into most modern motherboards. Thisdevicesenses the CPU voltage requirements (usually via sensepinson the processor) and calibrates itself to provide thepropervoltage to run the CPU.
