Figure 1. Power Supply Cabling for the dc7900 CMT Systems Note This illustration is Figure 7-3 of the Technical Reference Guide for the HP Compaq dc7900 Series. The main ATX specification is also supported by supplemental specifications, such as MicroATX and BTX-similar standards that focus on the mechanical interfaces (large system vs. small system) rather than the electrical interfaces or power supply. The Power Supply Design Guide for Desktop Platform Form Factors (http://www.formfactors.org/FFDetail.asp?FFID=13&CatID=2) is a supplement to the ATX specification that specifically focuses on power supply standards to support the different form factor produced by the PC industry. While this design guide defines different standards for power levels and mechanical form factors, it continues to support the same ATX12V interface described above. These mechanical form factors include ATX12V, SFX12V, CFX12V, LFX12V, TFX12V, and FlexATX. 3
