Hi In order to furnish a new RTX 2070 graphics card, I've migrated all internal parts from the Aurora case to a new generic case. However, this being an Alienware mainboard, the power jumper is not the generic two pin header configuration, as shown as component 17 in this diagram: [URL] In fact, the power on for the mainboard seems to come into an "LED Connector" (component 17 from link). Would anybody know the pin outs for this connector, and whether I could isolate the power on headers? Richard
