I've got a Xbox one s that won't say turned on in 1 second it will shut off again...

My console is no longer under warranty, and I have concluded that it is the power supply. I've tried another HDMI, I've even looked at a forum on the website and it is what I've experienced. The console turns on for a few seconds then shuts itself off.
Luckily I'm looking to get an Xbox One X or S soon.
