[Solved] ATX Power supply issue

Hello everyone!

I was testing my printer with an ATX power supply, everything was working until I decided to cut down the messy wiring coming out from my ATX power supply and leave only the ones that I needed, so I left only those 4 cables from 12v, the green (PS-ON and a black GND to close circuit) but this time, the power supply went broken...
When I plug it, it just light on the RAMPS led and PS fan just shake briefly, then everything goes down to nothing, and thats all, nothing happens

WHYY!!? I just made cables shorter, everything was sealed with insulating tape, any ideas about what happened?

There is usually a 3.3V sense wire connected to one of the orange wires in one pin of the 24 way connector. Sometimes it is brown or maybe a thinner orange. If you separate that from the orange it may cause the PSU to shut down.
