Connecting Power Cables
NOTE
Failure to use the appropriate power supply and/or not connecting the 12 V (2x4) power connector
to the desktop board may result in damage to the board or the system may not function properly.
See Table 3 on page 13 for power supply requirements.
The 2x12 main power connector on the desktop board is backwards compatible with ATX12V
power supplies with 2x10 power connections. Use of the 1x4 power connection is recommended
with ATX12V power supplies with 2x10 connections when using PCI Express video cards that can
consume up to 75 W. Figure 27 shows the location of the power connectors for a 2x10 power
supply.
