I am trying to down tune the output voltage of a 90w 4.5amp 20v lenovo power supply.

If I down adjust it to 12v, what would be the power rating? I am hoping it stays at 90w and the output current can reach 6amp.

hi. newbie here. I want to exchange knowledge with folks here.

I have modified a dell adpater. now on to my second voltage adjustment work, a lenovo 90w 20a supply. I want to down adjust it to 12v. I have located the 2.5v resistor feedback chain. and ready to change the BOTTOM resistor values.

Now the question is, after I tuned it to 12v, do I get higher than 4.5A output rating? giving I have a 90w supply.
