Intel Desktop Board D510MO 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 33. The test configuration was defined as

llows:

• 4 GB DDR2/667 MHz DIMM

• USB keyboard and mouse

• LAN linked at 1 Gb/s

• DOS booted via network (PXE); system at idle

• All on board peripherals enabled (serial, parallel, audio, …)

2.7.2 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 34. The test configuration was defined as follows:

• 4 GB DDR2/667 MHz DIMM

• 14.1-inch LCD via LVDS

• SATA DVD-R/W

⎯ Load: DVD pl

ayback

• 3.5-i

nch SATA hard disk drive, running Microsoft Windows Vista Home Basic

⎯ Load: continuous read/write benchmark

• Intel Z-U130 USB Solid-State Drive (or compatible device) on the USB flash drive

header

⎯ Load: continuous read/write benchmark

• Wireless card on PCI Express Mini Card slot, connected via 802.11n protocol

⎯ Load: continuous read/write benchmark on remote share

• Riser card on conventional PCI slot, populated with PCI LAN card, running file

transfer through local network to SATA hard drive

• USB keyboard and mouse
