Intel Desktop Board D845PEBT2 Technical Product Specification 2.11.5 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. Refer to Section 2.11.3 on page 79 for additional information. System integrators should refer to the power usage values listed in Table 55 when selecting a power supply for use with the Desktop Board D845PEBT2. Measurements account only for current sourced by the Desktop Board D845PEBT2 while running in idle modes of the started operating systems. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the following recommendations found in the indicated sections of the ATX form factor specification. • The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2) • The current capability of the +5 VSB line (Section 4.2.1.2) • All timing parameters (Section 4.2.1.3) • All voltage tolerances (Section 4.2.2) For information about The ATX form factor specification Refer to Section 1.4, page 17 82

Power Supply Considerations
CAUTION
The +5 V standby line for the power supply must be capable of providing adequate +5 V standby
current.
Failure to do so can damage the power supply.
The total amount of standby current
required depends on the wake devices supported and manufacturing options.
Refer to
Section 2.11.3 on page 79 for additional information.
System integrators should refer to the power usage values listed in Table 55 when selecting a
power supply for use with the Desktop Board D845PEBT2.
Measurements account only for current sourced by the Desktop Board D845PEBT2 while running
in idle modes of the started operating systems.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the following recommendations found in the indicated
sections of the ATX form factor specification.
•
The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2)
•
The current capability of the +5 VSB line (Section 4.2.1.2)
•
All timing parameters (Section 4.2.1.3)
•
All voltage tolerances (Section 4.2.2)
