I have noticed a mark on the yellow transformer inside my PSX original power supply unit. The mark appears to be a burn mark and I can feel it with my fingers that it is raised like a bubble on the top of the transformer, see image below with discoloration next to the text on the top of the transformer.

So I think I should replace the power supply unit as a safety measure.

I seen a USB-C powered replacement power supply unit from Robot Retro, is this a good reliable replacement option ?
