Converting Variable AC Power Supply to 90 to 130VAC


Thread Starter


I have a 200W ATX SMPS.
Where I live there is a power shortage of AC power supply. It some times reduce to 150VAC from 220VAC and my PC restarts itself.

I have set the input voltage switch to 230VAC. I can not set the input voltage switch to accept 115VAC because it will damage the power supply. I want to make a electronics converter that can convert the variable AC voltages to 115VAC 50/60Htz and set the ATX PSU power input switch to accept 115VAC instead.
Can you please tell me how can I do this?

And what this idea should work?
You could also look for a power supply that will work from (say) 90 to 265V without needing to be switched.
