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 32. The test configuration was defined as follows:
• 2 GB DDR2/533 MHz SO-DIMM
• 20-inch LCD display through DVI-D port
• 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 Desktop Board D945GSEJT Technical Product Specification
56
• 2.5-inch PATA hard disk drive
⎯ 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 third-party modem and disk
encryption add-in cards
• USB keyboard and mouse
• Back and front panel host-powered USB devices (other than keyboard and mouse)
at or near 500 mA
⎯ Load: continuous read/write activity on external drive/peripheral
• LAN linked at 1 Gbps
⎯ Load: continuous read/write benchmark on remote share
• All on board peripherals enabled (serial, parallel, audio, …)
Table 32. Maximum Load Configuration Current and Power Results
Subsystem Current Draw at 12 V Power Consumption
Minimum Load Configuration 1.02 A 12.28 W
SATA DVD-R/W 0.29 A 3.48 W
3.5-inch SATA hard disk drive 0.525 A 6.24 W
2.5-inch PATA hard disk drive 0.3 A 3.6 W
Intel Z-U130 USB Solid State Drive
(or compatible device)
0.31 A 3.72 W
Wireless PCI Express Mini Card 0.15 A 1.8 W
PCI cards on riser 0.19 A 2.28 W
Host-powered USB devices (other
than keyboard and mouse)
0.72 A 8.64 W
Maximum Load Configuration 3.505 A 42.04 W
En 40W AC/DC-adapter borde med andra ord räcka ganska långt.
Om du inte ska lasta den mycket kanske detta räcker:
