Power supply overloaded, is my PC broken now?

My Power supply exploaded after getting 230V instead of 115V, is my whole PC broken now or only the Power supply?

you wont know till you can replace the psu. if its a cheap 1 it will likely not have over voltage protection. if it was a quality unit then it may have just blown the psu... it really does depend on a lot of variables.
the only way to be sure is test another psu.

When getting a new power supply, Look for a full range unit. Most of those Full Range units are also of better quality(and more efficient) than the older ones that used a voltage doubler to operate on 120 volts.

With any luck, as said above, the power supply may have taken all the damage.

It was a TR 600W with a 115V/230V switch. And i managed to turn it from 230V to 115V and BOOM. the PC was off while doing it and the psu was grounded. It is melted now but the motherboard looks fine, but i still dont really know if it will work... can the rest be damaged too? (graphic card, HD etc.)

looking at the specs of that unit i would say you will be lucky if it hasnt damaged any more of your pc. reason being it takes up to 80a to trip the 12v rail which means the rest of the system can be exposed to very high amperage before the psu cuts out, which will result in damage. modular units that use 2 or more rails will often trip at much lower amps.
the next casualty will likely be anything that directly connects to the psu, such as sata devices or the motherboard so they will have to be properly tested also... but start with a new psu and work from there.

Doesn't sound good. I'll buy a new one and see if it works. Thanks!

My hope(I prefer to be an optimist here) is you tried to use a voltage doubler(2 large caps) with a voltage well over what they are made for and just smoked them instantly. I just looked in an old 250 watt unit and it has 200 volt caps in that section of the unit(120 volts rms should have a peak of about 168 volts, while 240 volts rms has a peak of about 336 volts)

Also, It would be overvoltage that would kill parts and not over current(If for some reason the power supply was not smart enough to see that it was unable to switch at the needed speed for the incoming voltage.).

Parts do not take current they do not need(I have run 3/4 watt devices with 30+ watt power supplies without issue because they only take the power they need and the power supply only puts out what is needed.). Hell I have plugged in hobby projects to car batteries with enough current to melt the full project, but current simply does not get forced.

No way to be sure until you replace it.

I just tried to test the Motherboard with a 250W psu instead of the needed 600W. I ONLY connected the MOTHERBOARD pin and after booting the Fans were working for about 2 seconds and then it turnd off. Im glad something reacted. (Im gonna test a 600W psu later).

My question is, is this a good sign or not?
Is my PC able to work again with all the pins (MB, HD, Graphiccard) connected and a 600W psu?

The 250 watt power supply most likely just shut off due to overload.

You will only be sure when it is ALL connected to a new power supply.

Hello again,
Well a week passed and i managed to get a new 600w power supply. After connecing all pins i turned my PC on and the same thing happend like before. My PC turned on for 1 second and then turned off, after trying it twice i could even smell something from the motherboard (or CPU).

Just to say, this is the second time i could smell this. The first time it said: "CPU over temperature", but the PC didnt turn off. I have a good cooling system and i dont know why this happend.

I dont really know where the porblem is now, but im going to try to change the MB. Hope you guys are still here and hope you will be able to tell me where the problem is. Thanks.

when you smell burning theres something definatly wrong... blue smoke is also another sign.
sounds to me like your pc is toast as far as the motherboard cpu and new psu goes. cpu overtemp means your cpu wasnt getting cooled. smoke coming from it likely means you killed it... reason ether your cooler isnt secured properly or the cpu wasnt fitted properly. what ever happend its a disaster...

time to get it to a shop and have some 1 who knows pc's look properly at it. stay clear of the likes of the pc world tech guys, they charge way to much just to look. maybe look in your local paper for a no fix no fee 1s over.

Cooler should have worked, maybe it happend because there was a blackout and my PC didnt really turn off for about 5 seconds even without power.
Then, after turning it on again, the error message showed up. I think that the MB has to be broken because there was no beep at all. Im gonna replace it with a new one and see if the CPU broke or not.
Thanks for your reply.
Gonna get expensive.

your not kidding. plan on replacing the cpu and ram also...
