(or other PC enclosure) internal connector, without the SigC6678-4 card installed and with the
top panel or lid open on the enclosure, boot the machine, and use a voltmeter (set to DC volts) to
measure the pins. Measured voltages for the external power cable should match up to the pin
assignment shown in Figure 3-6 below:
Figure 3-6, 6-pin external power cable pin assignment
Figure 3-6 above shows voltage pin assignment for the 6-pin end of cables shown in above
figures and pictures. Notes about Figure 3-6:
•
View is facing the connector, i.e. as if you're "standing" on the card, looking at the end of
the cable
•
COM means Common, or Gnd
•
Some cables may "break out" the 6 wires, for example Figure 3-4 above shows the 6
wires distributed among 3 peripheral power connectors, in 2-wire pairs (one +12V wire
and one Gnd wire for each pair). For the SigC6678-64 card, at least 4 wires (2 yellow, 2
black) should make electrical connection
•
These connectors are sometimes called PEG connectors (PEG = PCI Express Graphics).
Using this terminology may help when ordering cables and/or connectors
