RE: Zalman HD160XT and Thermaltake DH102 cases powering

On the Zalman case, the screen has two cables... the USB cable for the touchscreen layer and a standard 4-pin Molex peripheral cable (such as used to power an older non-SATA IDE harddrive).

The touchscreen layer needs 5v (and of course a ground) from the USB cable.

The screen uses the 12v and one of the grounds from the Molex peripheral cable.


The 4-pin cable pinout is 5v-ground-ground-12v and is described here:

I have a separate linear supply that generates unregulated 18v and provides regulated 12v and 5v on two separate Molex cables.

The Molex cable for 5v is used to provide power to the devices connected to the motherboard USB header (touchscreen layer & wireless mouse) as shown here:

On this connector, I left the 12v pin out.

The Molex cable for 12v is used to provide power to the screen's Molex connector. On this connector, I left the 5v pin out.

Your screen likely needs 5v and 12v as above, but it sounds as though you have different feed points through the 24 pin extension cable and possibly the internal PCB. Does this sound right?

What are the connections like between the internal PCB and the screen?
