Final Thoughts

It’s not often that a product like the Miller XMT 300 PC power supply crosses our test bench.  When the opportunity arose, I jumped at the chance but in hind sight experiences like this can be humbling.   Luckily the fire was quickly put out, no one was hurt, and damage to the power supply test bench was minimal.  I expect to have repairs completed and to be back in business very soon.

 

The Miller XMT 300 PC power supply performed exactly as advertised and while I would not consider my limited testing conclusive, it produced very good results.  Clean, virtually unlimited power, and high efficiency make this unit very attractive.  And that whole flux capacitor in a temporal distortion field +5VSB thing is very innovative and down right amazing!  But to be realistic, this is some serious overkill.  If you are looking for the biggest, baddest, power supply on the planet, then this is it!  But you better have a truck, a couple of strong friends, and very deep pockets.

 

As you might expect, the Miller XMT 300 PC power supply is rather expensive (and availability is very limited).  Models in the Miller XMT series start at $3,523.00 USD.
