CAUTION

Failure to use an ATX12V or SFX-12V power supply, or not connecting the additional power supply lead to Desktop Board D845PEMY may result in damage to the desktop board and/or power supply.

Desktop Board D845PEMY supports a single Intel Pentium 4 processor or Intel Celeron processor. Processors are not included with the desktop board and must be purchased separately.

The processor connects to the desktop board through the mPGA-478-pin socket. The Intel Pentium 4 processor or Intel Celeron processor may be removed and replaced with supported higher speed processors.

Desktop Board D845PEMY supports the processors listed in Table 3.
