800XL Replacement Power Adapter

[lord_mike]

Hello, everyone! While I've been a long time AtariAge member, this is my first time in the Atari computer forum. I hope you folks can offer some advice on a rummage sale purchase. I recently acquired a working 800XL unit. Thrilled, I brought it home and everything worked great! While searching this forum on another topic, I discovered that some of the power supplies for this model tended to die violently with a huge spike in voltage destroying the computer. Unfortunately, it looks like the power adapter I have is of the infamous Ignot design:

 

 

Fortunately, I tested the output with a multimeter, and it was outputting a nice 5.14 volts unloaded. Still, I was nervous about the whole thing, so I went looking around for another power supply. Low and behold at the same rummage sale the next day, they had this puppy:

 

 

2.8 amps at 5 volts, a switching power supply which I think should be more reliable. The unloaded output is the same 5.14 volts as the original power supply. It is much smaller than the original Ignot, but that shouldn't make a difference, should it?

 

What do you think? Can I use this to safely replace my 800XL ignot power supply after cutting the cords and splicing them to the DIN adapter?

 

Your advice and opinions are greatly appreciated! Thanks in advance!

yes, that should work well. 2.8 amps is more than you need, and also allows room for upgrades in the future, which usually increase current consumption some, and still have more. Just be sure to triple check the polarity before you plug it in.
