~ HDD LED
~ Speaker ~ Fan front ~ Fan rear ~ USB (Black cable- 2.0) ~ Front panel audio 2 / 4
~ USB 3.0
> Connect the following connectors from the power supply:
~ CPU power ~ Main motherboard power
Read the motherboard specifications to select the motherboard with the required features. - Find and install the correct motherboard.> Under Workbench, select Hardware.> Under Shelf, expand Motherboards.> Find the correct motherboard.~ For a motherboard, select Details.~ Select the Specifications tab.~ Read the motherboard documentation to identify the supported features.~ Close the details window.~ Repeat step 1b until you find a motherboard that meets the scenario requirements.> Above the computer, select Motherboard.> Drag Motherboard, Socket 1151 to the motherboard plate in the computer case.
Use the motherboard specifications to locate the required connection ports.> From the Selected Component pane, select Details for the motherboard.> Select the Specifications tab.> Read the documentation to identify the location for the following connectors: ~ #4 Fan front ~ #4 Fan rear ~ #9 USB 3.0 connector ~ #13 Power switch ~ #13 Power LED 3-1 pin
(Note: There is a spot for a 2-pin and a 3-1 pin power LED connection the
motherboard. Make sure to use the 3-1 pin connector.)
~ #13 HDD LED
~ #13 Speaker ~ #14 USB 2.0 connector ~ #18 Front panel audio ~ #2 CPU power ~ #2 Main motherboard power
Connect the system case connectors.> Select the computer case.The available connectors are shown in the Selected Component pane.> From the Selected Component pane, drag the connector to the port location on the motherboard. If necessary, zoom in to get a closer view of the motherboard.> Repeat steps 3b until all the case connectors are connected to the motherboard.
Connect the power supply power cables to the motherboard.> Select the power supply. 3 / 4
> From the Selected Component pane:
~ Drag the Connector, Power Supply, 20+4 pin connector to the port on the motherboard.~ Drag the Connector, Power Supply, 8-pin connector to the port on the motherboard.
