Intel Desktop Board D2500HN Technical Product Specification 2.7 Power Consumption Power measurements were performed to determine bare minimum and likely maximum power requirements from the board, as well as attached devices, in order to facilitate power supply rating estimates for specific system configurations. 2.7.1 Minimum Load Configuration Minimum load refers to the power demand placed on the power supply when using a bare system configuration with minimal power requirement conditions. Minimum load configuration test results are shown in Table 23. The test configuration was defined as follows: • 2 GB DDR3/800 MHz SO-DIMM • USB keyboard and mouse • 15-inch LCD display via VGA port • 3.5-inch SATA hard disk drive running Microsoft Windows 7 • LAN linked at 1000 Mb/s • DOS booted via network (PXE); system at idle • All on board peripherals enabled (serial, parallel, audio, ...)

2.7
Power Consumption
Power measurements were performed to determine bare minimum and likely
maximum power requirements from the board, as well as attached devices, in order to
facilitate power supply rating estimates for specific system configurations.
2.7.1
Minimum Load Configuration
Minimum load refers to the power demand placed on the power supply when using a
bare system configuration with minimal power requirement conditions.
Minimum load
configuration test results are shown in Table 23.
The test configuration was defined as
follows:
•
2 GB DDR3/800 MHz SO-DIMM
•
USB keyboard and mouse
•
15-inch LCD display via VGA port
•
3.5-inch SATA hard disk drive running Microsoft Windows 7
•
LAN linked at 1000 Mb/s
•
DOS booted via network (PXE); system at idle
•
All on board peripherals enabled (serial, parallel, audio, …)

Maximum Load Configuration
Maximum load refers to the incremental power demands placed on the power supply,
augmenting the minimum load configuration into a fully-featured system that stresses
power consumption from all subsystems.
Maximum load configuration test results are
shown in Table 24.
The test configuration was defined as follows:
•
4 GB DDR3/1066 MHz SO-DIMM
•
24-inch LCD via VGA
•
SATA optical disk drive
Load: DVD playback
•
3.5-inch SATA hard disk drive, running Microsoft Windows 7
Load: continuous read/write benchmark
•
Riser card on conventional PCI slot, populated with PCI LAN card, running file
transfer through local network to SATA hard drive
•
USB keyboard
•
PS/2 in 1 mouse
•
Serial mouse via COM port
•
HP LPT printer via LPT port
