Connecting Power Supply Cables
NOTE
Failure to use the appropriate power supply and/or not connecting the 12 V (2x4)

system may not function properly.

ATX12V power supplies with 2x10 power connectors. Use of the 1x4 power connector
is required with ATX12V power supplies with 2x10 connectors when using PCI Express
cards that can consume up to 75 W. Figure 28 shows the location of the power
connectors
