He's got the SVGA board in the P3. If he hasn't done the higher current mod to the K3 to get enough current out of that jack to run the P3 and SVGA, chances are it will trip the auto resetting fuse in the K3. I didn't do the mod to mine when I got the SVGA board, I just connected the P3 directly to my power supply terminals rather than open up the K3 at the time.
