Product: HP EliteDesk 800 65W G3 Base Model Desktop Mini PC

Good evening, 

 

I recently acquired the noted HP EliteDesk 800 G3 65W system.  It came with a 90W power supply.  It powered up, booted, shut-down.  I got it to power up a couple more times and now I am receiving the 3-long, 4-short beep/error cycle.  I noted in the troubleshooting section that this error is related to power issues.  I checked the power supply and it is showing a voltage of 19.5V, which seems normal but I know this may be deceiving and could still be an issue.

 

One other observation: though I have not been able to find any documentation on it is the led on the MB, right by the AC plug flashes on/off and then the led on the MB by the power button comes on and stays.

 

On a long shot, I also reset the CMOS but that had no affect, I am still getting the same beep errors and absolutely no activity from the fans, etc.

 

What I would like to verify is that I have the right wattage power supply for this unit as it seems as though the one I have may be under-powering.  Trying to find a  part number for the power supply and/or by wattage, what this machine actually needs?
