Step 5 Attach Cables

Connectors
The Merlin DP PCI motherboard includes many connectors. Connection
instructions, illustrations of connectors, and pinouts are supplied in the
following screens.
Cable Connector Ends
When connecting chassis connectors to the motherboard, make sure to
connect the correct connector end. Most connector wires are color – coded.
Match the color of the wires leaving the switch or LED to the same pin on the
connector end. There may be more than one connector with the same color –
coded wires. If so, follow the wire to the switch or LED. All motherboard
components are outlined by a white rectangular box with a broad arrow at one
end. Pin 1 is always at the arrow end of the white outlined box.
Connect Power Supply
The power supply should match the physical configuration of the chassis.
Make sure the power switch is off before assembly. Before attaching all
components, make sure the proper voltage has been selected. Power supplies
often can run on a wide range of voltages and must be set (usually via a
switch) to the proper range. Use at least a 250 watt power supply, which should
have built – in filters to suppress radiated emissions.
Connect Power Cables
Attach the power supply cables to the power connector (P1 and P2) on the
motherboard. AT – compatible power supplies have two six – pin connectors,
attached as shown below. The six – pin connector on the power cable with
three red wires and two black wires is attached to P2. The other connector on
the end of the power cable is attached to P1.
