Intel D845GLAD Product Guide - Page 17

Desktop Board Features CAUTION Power supplies used with this board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the Intel desktop board may lose register settings stored in memory. For more information on standby current requirements for these desktop boards, refer to the TPS by selecting the Technical Documentation link at: http://developer.intel.com/design/motherbd/ Hardware Management • Power connectors • Fan connectors • Resume on Ring • Wake from USB • Wake from PS/2 keyboard/mouse • PME# wake up support Power Connectors Desktop Boards D845GLLY and D845GLAD have two power connectors.
