hi there,i am sending a pc to a friend from australia to the philipines,in aus we have 240volt power,the philipines has 220volt power,will this be a problem for the computer,my friend will be using the correct adapter to plug to the wall,and the power supply is a ANTEC true power 500watt,my friend will also use a power regulator,coz i believe the inconsistent amps can kill the computer..any help is much appreciated..thanks

If the unit has Active PFC it shouldn't be a problem.
You can check by looking at the back of the PSU and if there is a small switch (not the power switch) similar to what left of the plug on this one.

If thats there, you dont have Active PFC. You'l have to make sure that switch is at the right setting before it gets plugged in at the Phillipines.

If its not, perfect, there's no issue I can think of.

from what i can see the psu does not have that switch,and my current pc has a truepower 650 and it has no switch beside the power switch,looks like it should be fine,thank you for your assistance

240 and 220 volts are so close that even if the unit does have the switch (to select between 230 volts +/- 10 volts and the ~110 volt standard it will work with just the adapter).

They might use 220 volts at 60 hertz over there instead of 240 volts at 50 hertz.

So long as the 220 volt circuit he has provides more than 2.5 amps (I imagine it would provide at least 9 amps) he should be fine.

Hi


In UK we use 240V most of the rest of Europe use 220V but both have agreed to call the voltage 230V (without actually changing anything)

only very old 220V equipment would have problems running at 240V
(possibly electric heaters or cookers)

USA uses 110V 60Hz Europe uses 230V 50Hz many computer PSU have a switch or can auto detect voltage.
