HP Compaq 6000/6005 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. This document explains the new HP - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 3
. 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 - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 4
by notebook PCs and some smaller form factor desktop designs (i.e., the HP USDT form factor). For many reasons, the notebook PC industry has not HP Personal Systems Group (PSG) that produces consumer and business PC products.

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 - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 6
the MT rear chassis 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 - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 7

new power supply for HP business PC products. First, the increasing regulatory focus on power consumption is forcing the industry to explore innovative solutions to meet increasingly strict product requirements. Second, there is an increasing emphasis on smaller form factor PC products, and the size - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 9
the cable. More wires create a less flexible 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 - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 10
can be used generate these lower voltages. The new HP power supply architecture utilizes +12V to generate lower 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 - Compaq 8000 | HP Enterprise/Mid-Market Desktop PC Power Supply Architecture - Page 11
