It looks like a stock PSU, which is very advantageous over the new Microsoft PSU. This started causing problems such as B. Temporarily no connection from the chord to the transformer unit. The seller asks for a one year warranty but I couldn't get hold of them. I had to go through Revain customer service which they replaced. So I have a new PSU on the way. Microsoft's original cable only lasted about a year before failing. Maybe I need to get new ones regularly.
