Well it's time to look at the business part of the Power Down Protector. The P.D.P is approximately 2 inches square when including the tab portion with the mounting holes and approximately a half inch tall. Here is what it looks like from the top, back, and bottom. The top of the Power Down Protector is silk screened with the connector names so its pretty easy to identify which is which. The second picture shows how the internal components are attached to the anodized aluminum case with two plastic "rivets".
In the last image above, you will see the jumper settings to set the amount of time that the fan(s) will stay on after you shut your computer off. The next two images are the left and right images of the connectors.
Here is a nice feature if you happen to wear off the silk screening on the top of the P.D.P. The PCB (Printed Circuit Board) has the connector names printed underneath the connectors, although its kind of hard to see them.
