I tried googling first but couldn't find the answer. I bought this over a year ago in a garage store. A strange behavior happened just yesterday for the first time that I don't know if it's normal or not. This has been connected to a wall outlet ever since. Plugged in to this are all my sim rig equipment. After playing yesterday, after pc shutdown, I turned it off like I normally do every time but all my other equipment are still 'on'. As I'm typing this, the UPS is off, turned on all equipment and everything is running. Is this normal? Anyone encountered this? Thanks in advance.
