The PX3 should draw no more than about 200 mA from the 12V supply.
When power is first applied, there will be some inrush current due to the filter capacitors but I'm surprised that's enough to blow a 1A fuse.
Is it a fast-blow type fuse? Perhaps a slow-blow type would solve the problem.

My PX3 Is fused with a 1amp ATC fuse once in a while the fuse blows. I believe the fuse blows when the power is first turned on. What does Elecraft recommends? Nothing else is connected to this fused line except the PX3.
