CAUTION
Failure to use an ATX12V power supply, or not connecting the additional power supply lead to the
Desktop Board D845EPT2 or D845EBG2 may result in damage to the Intel desktop boards and/or
power supply.
The Desktop Boards D845EPT2 and D845EBG2 support a single Intel Pentium 4 processor.
Processors are not included with the Intel desktop boards and must be purchased separately.
The processor connects to the Intel desktop board through the mPGA-478-pin socket. The Intel
Pentium 4 processor may be removed and replaced to accommodate supported higher speed
processors.
The board supports the processors listed in Table 2.

The Desktop Boards D845EPT2 and D845EBG2 require an ATX12V compliant power supply to
function according to Intel desktop board specifications. Both Desktop Boards D845EPT2 and
D845EBG2 have two ATX12V compliant power supply connectors that are needed to provide
extra power to the Intel 845E chipset and Intel Pentium 4 processor.
Items A and E in Figure 15 on page 64 show the two power connector locations.
