Today while cleaning and packing up from a LAN I went to, my friend noticed that my PSU was set on 230 volts instead of 115. I remember that from the birth of my computer to some point in time, the voltage was always set on 115 as is standard in America...so, what does this mean?

What kind of problems could I have caused and could someone explain the dynamics of the whole PSU voltage thing?

Thanks!

It should still be fine, switch it back to 115 though. I used to do it on the scool computers all the time... last thing the tech guy could think of

Of course I switched it back, but I'm still kind of worried about the components in my system and whether they MIGHT have been affected.

Any thoughts on how the individual pieces of my computer were affected?

personally, ive had this happen as well ... but my comp wouldnt post at 230 ... and none of my stuff was damaged ... all the best of luck that nothing got damage (which i believe it didnt)

Nothing will happen, Im not an expert but if your computer is still working currently I see no reason for it to stop just because of that switch you flipped.

If the comp is still working it is probably all ok. If you want to test individual componets search for and DL a program called "PC Check" and a program called "Tuff Test" and use those to test and see if anything is damaged.

ya that happnd to my parents computer cause my older brother switched even though it had the tape so idiots wont. it fried the PSU and the floppy drive and melted the connector on the floppy thing. so they bought a new computer EVEN though all they needed was a new PSU, but its old so they did it anyway.and i got it and fixed up an deverything else was fine new folder for me!

Shouldn't it technically be impossible for a PSU to draw that much current since U.S. current only supplies 110v? How could it draw twice that much if that much current wasn't even coming out of the wall?

true it only works if power originally pushes the psu tha far. it should have no effect at all on the components since the psu lowers volts to your computers needs.

HAHAHAHAHA that is what im doing tommrow

Everything is running normally and I haven't noticed anything different about how my computer behaves or anything to that effect.

I'm happy to hear that it shouldn't have done any damage to my computer and I appreciate all the input.

Thanks!

At 220V your PSU would be drawing half the current (if it would work) than at 120V. However, you didn't have 220V coming into your PSU. The outputs would be the same at either voltage.

I am suprised your system worked at 220V, but nevertheless, your system is fine. It's not as if you were outputing twice as much

offtopic... wow nemo quoted me too!

heh... in europe if you switch to 110v you blow your psu up... usually with a big bang...

think about it. If it is at a mode for higher voltage, then it still has to deliver the same amount of power to the components. So if it is receiving twice the voltage, the circuit will need twice the impedence. So your PSU will just be giving off less power than necessary.

I knew somebody that did that to one of the old IBMs at our school....th IBM did not like that at all. It immediately cut itself off. When i turned it back on, i had a BSOD, and had to do reinstall everything. It was never the same after that though...it died a few weeks later, mobo problems.

it didn't do anything bad all it would do is undervolt your comp becasue it switches between two different resistors which as most know will make a comp unstable but the thing you have to wory about is if you go to europe and leave the swich that is how things fry

I think you are fine, I don't think you damaged anything.
