[SOLVED] PLEASE HELP! Burning smell & won't turn back on!

[HelpPleaseHELP]

So I smelled a burning plastic smell & it was coming from my brothers PC tower. It was already off & looks like the dog knocked the tower on its side.
I shut it off completely & waited about 1 hour. It will NOT turn on. I can't see any melted plastic components or wires. I can't identify where the smell came from (I tried the toilet tube but it smells kinda everywhere).
He's going to be so pissed! Please help me troubleshoot this.

UPDATE
I went and bought another PSU since it's the likely piece that fried.
I still don't understand how the tower being on its side could cause it to overheat to the point the PSU melted. There seems to be 6 different fans in there!
Also why the F doesn't the PSU have a failsafe against this?? 😡
My brother said the computer was off but I don't see how this could happen if it was.

UPDATE 2
Well the old PSU is outside his door so I guess I did good 😅
Thank you for your help everyone!

That sounds like a power supply.

Unplug the PC and take the PSU out. Does anything look or smell bad?

That's alot of dirt/dust build up you got there, something coulda made it's way inside somewhere it's not supposed to as well.

I don't see anything that looks melted/burned.... it seems to smell a tiny bit more coming from the wires out the back than the other components in the tower...

You can take that side panel off the case and examine the wire configuration, there might be something to observe.

Panel off the PSU itself? Would I need to unscrew the PSU and unhook all the wires? He's going to flip out if I mess with it.

If the PSU was damaged by melting inside could have damaged any other components in the PC or would just the PSU need replacement?
Thank you for your replies btw!

noooo...side panel off the case.
Do NOT open up the PSU itself.

Can a dying PSU affect other parts? Yes.

Ok the side panel from other side shows nothing physically damaged either but the smell definitely seems to come from the wires coming out of PSU.

The $95 PSU is no problem (probably even under warranty) but if the other parts are fried... 😱😱😤😣

Thermaltake SMART units are notoriously bad. I'm not surprised.

Can you show a picture of the rear of the PSU, maybe with a light so we can see inside the PSU? May be able to spot some exploded bits.

There is no way to tell what other parts may or may not have been affected, until you get a known good PSU and swap it in there.
And not a crappy one.

failsafe?

Well, Thermaltake is not a very good PSU.

Could have been a slightly loose connection, could have been the crappy PSU dying on its own, could have been a lot of things.

 

[NightHawkRMX]

I don't see if that unit has over temperature protection or not. It may or may not.

Lower end PSUs have less failsafes.

Could anything happen if the computer was off though? I think he accidentally left it on and this happened when it tipped over (or whatever the reason) but could not have if it was off.

It still has power going to it, so yes it could still fail

Ok interesting! But this would be good because if it was off but failed and melted because there was still a current, the PSU would be less likely to have damaged the other components!

I'm about to find out my brother will be home in 5 mins 😳
