The XEgs shipped with a 1 amp power supply.

The 800XL shipped with a 1.5 amp power supply.

I think there's a chance that could be your problem.  An 800XL power  
supply would be great for the XEgs, but the original XEgs supply might be  
a bit weak for the 800XL.

Lots and lots of Atari power supply specs here:
