Mew member with Carnetic P1900 issues
I am new to the forums and on the last stages of my first CarPC build and I am having difficulty with the Carnetix P1900 PSU.
I am running an Shuttle XS36VL Mini-PC that has Intel Atom D2550 dual core CPU with Intel NM10 graphics. Unit has external power brick that outputs 19V DC. Computer runs 19V at 40 Watts. I am also running a Samsung LMS700KF07-004 monitor that is 12V at 1.2 - 2.0 Watts with the LEDs at 15 - 25mA. So my rough calculation puts me at about 2.305A draw. I am using the P1900 to power both devices. Currently I am using a bench power DC output 13.3V at constant 10A for testing.
The P1900 will not power my devices. I have check all voltage from the power leads and I have 19V main and 12V secondary but it will run the devices to about the time the computer gets into Windows then it shuts off the secondary source (monitor) then within a few seconds shuts power off to the main (computer) then sits with an over current error code.
The P1900 is suppose to support both the 12V and the 19V simultaneous at 6A so I am confused as to why my P1900 keeps going into over load failure and shutting down?
Is it that I need higher amperage from the bench DC power source? Car battery puts out 40+ amps so is that the problem?
Does anyone have any ideas or suggestions?
