Intel Desktop Board D2550DC2 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 24. The test configuration was defined as follows: • 2 GB DDR3/1066 MHz SO-DIMM • USB keyboard and mouse • LAN linked at 1000 Mb/s • DOS booted via network (PXE); system at idle • All on board peripherals enabled (serial, parallel, audio, ...) Table 24. Minimum Load Configuration Current and Power Results Output Voltage 3.3 V 5 V 12 V -12 V 5 VSB Minimum Load 0.67 A 1.91 A 0.77 A 0.1 A 0.17 A 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 25. The test configuration was defined as follows: • 4 GB DDR3/1066 MHz SO-DIMM • SATA DVD-R/W  Load: DVD playback • 3.5-inch 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 Full-/Half-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 58
