Intel Desktop Board D945GSEJT Specification Update

INTEGRATOR’S NOTE

The board may be powered by using an external 12 VDC or internal 12 VDC power

supply using a 2 x 2 pin connector. Use of an external 12 VDC power supply is

preferred.

2. Update to the system power consumption information in Section 2.7 of the

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.

System Power Consumption:

Total Current Draw at 12V PSU Total Power Consumption

Minimum Load 1.02 A 12.28 W

Maximum Load 4.62A 55.44W

Subsystem Power Consumption:

Subsystem Current Draw at

12VPSU

Subsystem Power Consumption

2GB SO-DIMM 0.17A 2.04W

3.5in SATA HDD 0.525A 6.24W

2.5in PATA HDD 0.3A 3.6W

4965AGN 802.11a/b/g/n 0.15A 1.8W

Z-U130 USB flash drive 0.31A 3.72W

SATA DVD-R/W 0.29A 3.48W

Reserved header 0.925A 11.1W

PCI riser card w/PCI cards 0.19A 2.28W

Non-kbd/mouse USB ports 0.72A 8.64W

Therefore, motherboard power consumption is as follows:

• Board power at minimum load (system power at minimum load minus power from

SO-DIMM): 12.28W - 2.04W = 10.24W

• Board power at maximum load (system power at maximum load minus power from

all subsystems in table above): 55.44W - 42.9W = 12.54W
