Power Connector When used with an ATX12V or EPS12V compliant power supply that supports remote power on/off, the S875WP1-E server board can turn off the system power through software control. When the system BIOS receives the correct command from the operating system, the BIOS turns off power to the computer. With soft-off enabled, if power to the computer is interrupted by a power outage or a disconnected power cord, when power resumes, the computer returns to the power state it was in before power was interrupted (on or off). The computer's response can be set using the After Power Failure feature in the BIOS Setup program's Boot menu. ✏ NOTE A standard ATX 20 pin power connector and standard ATX 12V 4-pin 2x2 connector can be used to power the S875WP1-E board. Plug the power cables into the pin 1 end of their respective motherboard connectors, leaving pins 21-24 unused on the main power connector and 5-8 unused on the 12V connector.
