[SOLVED] Accidentally switched power supply voltage

[Abu Aso]

Ok so about two weeks ago I switched my psu voltage and my pc does not turn on anymore, I did not realize the cause of this was me switching the voltage so I don't remember what voltage I changed it to (115v to 230v or 230v to 115v). So my question is, did switching the voltage only killed my psu or my entire system?
Thanks!

What is the electricity in your location?
110v (US) or 230v (elsewhere).

I don't know but I googled what voltage my country operates it said 230v 50hz. I live in Armenia.

There may be a fuse inside the supply. I would check this.
I think I recall doing something similar to what you did.

How do I check it? Sorry, I don't understand much about tech.

Ok.
If you switched it from 230v to 115v and powered it up...

Either a fuse inside the PSU is blown, or the whole PSU is dead.

What is the specific make/model of the PSU?

It is an delta psu.

 

[Archaic59]

It is an asus psu.

No, it's a Delta PSU with a max amp rating on +12 volt of 19 amps which means you only have 228 watts of power useable, if it's even still working properly.

Unless you have the know-how to replace the fuse, I would replace the PSU, if it is even standard ATX.

 

[USAFRet]

Replace it.

If you switched it to 115V, then the PSU is definitely dead. The 115V switch typically directs the AC input into a voltage doubler so the AC side can operate at 230V. So you can imagine what pushing 460V into a system expecting 230V will do.

sorry, it came with my asus case so I assumed it was asus.

No problem. Delta makes decent power supplies but with such a low amount of available power and an iffy model now that you've likely fried it, maybe replacing it would be a good idea.

So switching to the incorrect voltage only damages the psu right?

 

[NightHawkRMX]

My guess is since the damage is on the primary side it will not damage any of the other parts in the PC.

thanks!

Thanks guys!

Correct. The DC side that feeds the components are electrically separated from the AC side.
