Figure 2-6. All Connectors and Headers for the SD7-533
First, Let’s see the headers that SD7-533 uses, and what their functions are. We will show you all the
connectors and headers.
(1). ATXPWR1 and ATX12V1: ATX Power Input Connectors
The Pentium
®
4 requires a power supplier different
from the regular one. It’s a newly designed
ATX12V1 power with 300W, 20A +5VDC capacity
at least for heavily loaded system, and 720mA
+5VSB at least for supporting Wake-On-LAN
(WOL) or Wake-On-Ring (WOR) features.
Attach the connector from the power supply to the
ATXPWR1 and ATX12V1 connectors here.
Remember you have to push the connector from the
ATX power supply firmly to the end with the
ATXPWR1 and ATX12V1 connectors, insuring that
you have a good connection.
Note: Watch the pin position and the orientation.
