Power Connector (24-pin block) : ATXPWR
ATX Power Supply connector. This is a newly defined 24-pin connector that usually comes with an ATX case. The ATX Power Supply allows you to use soft power on momentary switch that connects from the front panel switch to 2-pins Power On jumper pole on the motherboard. When the power switch on the back of the ATX power supply is turned on, the full power will not come into the system board until the front panel switch is momentarily pressed. Press this switch again to turn off the power to the system board.
We recommend that you use an ATX 12V Specification 2.0-compliant power supply unit (PSU) with a minimum of 350W power rating. This type has both 24- pin and the 4-pin power plugs needed.
If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin power plug can provide at least 15A on +12V and the power supply unit has a minimum power rating of 350W. The system may become unstable or may not boot up if the power is inadequate.
