Probably easier using a step up transformer.
What is that 7 legged IC on pic 1, almost center on the bottom?

maybe if you had a 120v model to compare against, it's just component differences?

How about adding the voltage doubler circuit before the rectifier or in place od rectifier bridge? Will that work?

The circuit was not designed to operate with an input of 110vac. It won't work unless you redesign the primary circuit for both the standby and main power supply section.
Just get a step-up adaptor for 110~220v, 200watt or replace the power supply with a north American one.

No one has got any experience on this???

Its 172v on main cap and 1.2v on 5v rail on the secondary side, nothing plugged in.

What do you get on the main filter cap? And that 1.2 V is on the 5V rail nothing plugged in?

Yes it has pfc circuit and I'm getting only 1.2v on the secondary which I think won't be enough.

Re: xbox 360 adapter - 240v to 110v

the caps are fine,
the fuse may need to be uprated, but i'm not sure if it has a PFC circuit and how it would react.
did you try it?

Re: xbox 360 adapter - 240v to 110v

Please find the attached pictures. I see most of the caps on primary side are rated for 420v. Do I need to replace them?

Re: xbox 360 adapter - 240v to 110v

have you opened it?
it may just need a bigger fuse.

Hi,

I have got a xbox 360 console from India where it has an adapter designed to work with 200v-240v (135 watts) and has o/p voltages of 5v 1A standby and 12v 10A as operating voltage. Is there any way to modify the same to work on 110v in USA?
