Went to MSI's website, they also don't mention the voltage or show the power brick, and still only show the older models.
I picked up a Lenovo stick computer a while back. It is pretty neat aside from having a decent sized USB brick for power, then needing more USB ports, so a hub.. and so on. One of these would be a useful alternative, and much faster.
If you use a monitor with a brick, this with a brick, then need a powered USB hub you are already up to three bricks that have to go somewhere. Back to an all-in-one or laptop for simplicity.
