ps3 fat psu modification

url]Hello all,

I have been donated a CECHL01/VER-001 motherboard that I put on a CECHK01/DIA-001 chassis/shell. Everything is a perfect fit except for the psu(3pin vs 4pin). I found some info on another forum from @Mr.Dutch

So I modded my cable to fit the 4 pin on the mobo( just removed the plastic prong)

But then I had no power, no standby light.Then I saw that pin 1 and pin 4 are both 5volts.so i tried connecting them with a wire and I had red stand by led and it also booted with green light(It was not connected to any tv)

I just left it for a few seconds.

My question is: Is it safe to permanently solder a wire from pin 1 to 4 ?
