Power supply not lighting up when plugged into Xbox but when not plugged in lights up.

I also have this problem. I plugged my power supply into my Xbox one and it lights up for a few seconds before the console turns off, only the power supply unit is always lit in orange.

I tried to light it several times this way and it is the same ride: it lights up for a few seconds before turns off and the power supply unit is always lit in orange.

I use the standard xbox one and the power supply lights up in orange when it is plugged in, but my xbox does not light up at all.

MY xbox power supply shows a green light when it is plugged in the wall only (not in the console yet) when plugged in the console too it shows a green light again but here the Xbox doesn't turn on. It's fan only powers on and runs really loud (burning smell
too). the Xbox doesn't respond. I heard when the Power brick is plugged in the wall only it needs to have an orange light not green.when plugged in the Xbox too then it goes green.

could this be caused by the power supply?

Sounds like a power supply issue

are you sure or is it a CPU issue what of the burning smell from the console when power supply is connected?

Is the orange light on the power supply solid?

When the XBox is off, the power supply light is orange. But when the XBox is turned on and working fine, the power supply is lit up with green. If the light is orange, it usually means a hardware problem with the XBox (like a broken disc drive, for example).
Before sending it in for repairs, try step 2 and if you can, step 3 below.

Is the orange light on the power supply flashing?

Step 1: Try plugging the power cable into a different plug socket. If the orange light turns to any other color than green or flashing orange, there is a good chance that your power supply needs replacing.

If the color turns anything other than green, also try this:

Step 2: Turn the XBox off and then unplug all the cables from the power supply starting with the one leading from the plug socket. Let it rest for up to 10 minutes before plugging it back in, making sure that every cable is in place, and
then turn the XBox back on. If still not green, try step 2.

Step 3: If you have access to a second power supply from the same version XBox (for example from a second XBox or a friend), try plugging it in and turning the XBox on. If the XBox comes on without a problem, you will need to buy a replacement
power supply.

If none of this helps, and even the alternative power supply lights up in orange with your XBox but works with its original machine, then your best option is to send it in for repairs. If your XBox is still under warranty the repairs should be free.
