My understanding is that it provides supplemental power to Pentium 4 processors, because they draw a lot of current. &nbsp;I have seen situations where it was not plugged in and there were no troubles, but it will alsmot certainly depend on if you experience any problems without it. &nbsp;Of course, you should consult the MoBo manufacturer for the final word on.

if there is a separate 4-pin plug on the motherboard, and you have a 20 pin power plug, you need it. It is only in the case you have a 24-pin power supply plug that you would not need it

I have an ATX motherboard that has the standard 20 pin power supply connector and it also has a square 4 pin power connector. The manual says it's not necessary to plug the power supply to this 4 pin connector. I was wondering what the 4 pin connector is for and would it hurt to plug the power supply to it anyway.<br />

thanks

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
