/6005 Pro Series and HP Compaq 8000/8100 Elite Series desktop PC products introduced a new PC power supply architecture designed to improve power delivery and efficiency in the face of new and challenging Energy Star and other regulatory requirements.

. 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 - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 4
The following sections summarize the power supply architectures implemented on HP Mid-Level/Enterprise PC products prior to 2009 and our transition to the current architecture. Each form factor utilizing internal power supplies employs a power supply architecture specific to the needs of the - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 5
standard interface. In summary, the CMT and MT power supplies follow the industry standard electrical interface, but have not supported a mechanical industry standard for many product generations. Small Form Factor (SFF) The HP Small Form Factor (SFF) power supplies are based on the CFX12V industry - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 6
fan. In summary, the SFF power supply has not been fully compliant with the CFX12V industry standard, either electrically or mechanically, for many product generations. Ultra-Slim Desktop (USDT) The USDT form factor has evolved significantly since the dc7700 product. The small size of the dc7700 - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 7

factor PC products, and the size and bulk of the current industry interface is a major obstacle to optimizing smaller form factors. Regulatory Requirements The global regulatory environment has changed significantly over the last 10 years. There is a very strong legal and industry emphasis on power - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 9
cable. Shorter wires in smaller form factors also create a less flexible cable. The previous SFF products suffered from both of these issues. The new power supply architecture removes +5V and +3.3V voltages and control signals from the primary high power connector, reduces that connector from - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 10
systems, regulate +5V and +3.3V on the motherboard. Other server and blade products have also removed +5V and +3.3V from the power supply output. PCs are trailing in this transition, but the USDT and All-in-One form factors with external power supplies have already moved in this direction. Removing - HP 6005 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 11
, HP Enterprise/Mid-market business PC products have not supported a formal power supply design standard for many product cycles. The mechanical standards were abandoned long ago, and the few remaining products that followed the industry's electrical standard have now been replaced by a new HP power
