If a power supply's main connector is "20+4 pin", will that connect to a motherboard that is "24 pin"

Update:

That is, is the 20+4 pin adaptable to the 24 pin motherboard?

    YES. It is actually a universal connector for both old (20 pins) and new (24 pins) motherboard.

    Because of the higher power requirement of new devices, the +3.3V, +5V and +12V lines were increased in motherboards w/ 24 pin ATX. See pins # 11, 12, 23 & 24 in link below. These are the "+4" pins.

    yes

    the 20+4 means the plug has two parts that join togeather to give you 24 pins. Or remove the 4 pin section for 20 Pins.

    Take a look at the web page below.

    Yes, they all come that way. It's so they're backward compatible with 20-pin motherboards.

    No. It will make a light high pitch buzzing sound when you plug it in though.
