CPU power cable, P3
CAUTION:
power is on. If you do so, the system board can be damaged and the warranty
voided. Ensure that you can tell which power cable connects to the PCIe x16
graphics card and which power cable connects to the system board. These two
cables have different pin counts and different colors. The PCIe power cable has
a 6-pin black connector, and the CPU power cable has an 4-pin white connector.
To see a picture of the PCIe cable and where it must be connected, see
and installing expansion cardson page
Internal USB 1 2x5
CAUTION:
The 2x5 connector can be mated to either
a wide 2x5 option cable connector or a
narrow 1x5 option cable connector.
To prevent damage to the connectors,
always connect a narrow 1x5 option cable
connector to pins 1,3,5, and 7 only of the
2x5 connector (pin 9 is not keyed on the
connector).
