Even if other 5V voltage is at zero?!
Does the exxos PSU replacement can be provided with the connector for my motherboard?
Does it make sens to replace the switch button too ?
Are there any other things they would be wise to take to pimp my 1040STE?

Other 5V?
Please take a photo and tell us between which leads you are measuring.

Both red are connected together on both PSU and motherboard. So it is a bit strange that you don't have 5V there.
Measured between one red and black right? And then the other red and the black?
Checked if there is a crack on solder joint on PSU? Clean connector.

Yes i measure it between one red and black, first red is ok, other red is 0 volt.
The strange thing is that the two red dots are soldered together on the PCB, so I should have both +5V !!!

@TheDark91
I just noticed that in your last post, the image was linked to on an external site. Please ensure you upload any images to the forum as an attachment and then add them in inline.
We ask that you do this to preserve the integrity of post images, as should an external site go down, then the image is lost permanently. you have done this in previous posts, and I will correct this one, but it is part of the forum rules that images are attached and not linked to.
Thanks

On that image it looks like a bad solder joint ? I think of that's the 12v output you posted ?

I would just resolder all the pins on the PCB for the low voltage side and see if that helps.
