@Thrasher - I have no other devices connected via USB. My setup is:
Via M10000 mobo
Creative Audigy 2 PCI sound card
40gb 2.5" HD
@Wiredwrx
I have connected the screen to the PS and never goes above 3a. I can verify that I am connecting the wires to the correct outputs on the molex (BATT cable -> yellow wire in molex, GRND cable -> black wire in molex). I can connect the screen via the ISO loom in the car and works fine, but I need this screen on a regulated 12v line.
Any other suggestions?
Thanks for your responses so far
John
