this is a brand new PC and apparently the PSU was set to 110v by default. i did not notice this and i plugged it into a 220V outlet and as soon as i did that i heard a very loud SPARK noise, no smoke whatsoever maybe a very very faint smell (not sure). this fried the PSU. Will changing the PSU alone make the device work fully again? or is there a chance that this fried other components aswell? edit: Id like to add that this spark happened as soon as i plugged in the power cable (i did not power on the system).

if the new PSU works, don't return it, because you can test it to see if it is all OK by running some tests.
But if you feel like it isn't worth it, then send it back.
Personally, I wouldn't send it back.... but I think I have a bit more of an understanding about this than you and it's about how confident you are.
It definitely fried the psu. At this point it is pretty much impossible to say that if anything else is damaged or not without buying a new psu and testing the system. If this was a good quality psu then you should have been lucky if the OVP tripped and psu died. If it didn't then some components might be damaged.
 


even if i did not power on the system there is still a chance other components got damaged?
 


If i change the psu and everything powers up fine does that mean that they were not effected whatsoever or will there be slight damages on them?( lower performance)
 
Basically, there is a gap between primary and secondary in a PSU - you don't need to understand this, but it means the primary may have died and with a little luck, it didn't get to the secondary part - which is the part that feeds your computer.

Can you list the make/model of the PSU?

I am pretty sure you will be OK - but there is a chance that you killed it all, sadly. As I said, just a chance, maybe 5% I would say that it's all dead.
 

I think the PSU is unbranded. It came with a prebuilt gaming pc from ibuypower.
 


Yes i did. Im waiting for the computer shops next to me to open to go try with another PSU they open 2 hours from now.
 


I have an option to return the system however this will take a month for the refund to get processed. Do u think i should return it even if the new PSU will make it work?

so i tried a new PSU and it worked up fine. it was running all high end games with extremely high fps too. i am most probably not going to send it back. what tests are you talking about that i can run exactly?
 


Maybe it was this statement that made it seem like he was pondering returning a system he blew up...; my mistake, i guess....

"I have an option to return the system however this will take a month for the refund to get processed. "

Perhaps you should re-read it, as well....
 


Yes return the system, because it was not setup for his country when he got it. He should have checked (although not many people would) and the people who made it should have checked it was correct before it left their shop. So he has every right to send it back, but he was sending back the WHOLE package, not trying to claim for a PSU to which he bought a new one.
 

hey buddy, they sent me a system not configured to work at my country, from my point of view i received an electrical device and as soon as i plugged it it blew up. I am not supposed to go take a class in electrical engineering or google how computer components work to be able to buy a PC, plus after i researched it the PSU should of been set to 220V by default anyways as a safety procedure since if a 220 is plugged into a 110 it wont fry it instantly as it did mine.
