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
