Hardware Power brick adapter 205w for Trinity xbox

[Hector Ludovino]

I have a Trinity xbox 360, with a power brick of a fat Xbox, with an adapter, when I plug the power brick it's show orange light. But when I tried to turn on the exbox it's turn on for almost 3 seconds then off. But the power brick stay with the orange light. When I tried with another power brick (factory one) it's turn on normally, what you think it is ?

The 203W bricks are the first generation ones. Its probably no good. I don't believe the adapters have any sort of voltage control.

It's likely your PSU is dying.
You could test the PSU on a phatty box if possible.
