Is it possible to kill a PSU this way......

post #1 of 12
Thread Starter 
Hey Guys,

So I get home today and get a shout from my mums computer room saying its broken.....

I walk in and Straight away I can SMELL something is wrong, I could smell burning and there was smoke coming from the PSU - To add to the situcation there was also a "No Signal" coming from the monitor.

So I quickly turn it off and open the case to take peek - Nearly burning my hand on the back of the case in the process

I notice that one of the CPU fan wires had slipped though the PSU fan gaurd and got trapped and therefore stopped the fan moving.

Now the PSU Gives a "No Signal".

Can a PSU burn out like this? Don't they have temp control to stop this happening? Mine turns off if it gets too hot

It is a No name 400W PSU that came with the PC (Prebuilt )

Anyone know?

Thanks

Well if you saw smoke I would be worried. I would try a new PSU to power it up and if it boots I would buy a new PSU.

Maybe. If the fan wire was grounded it's possible.

IT's cheap, i doubt it would have an auto shutdown.

By the sounds of it the PSU has either

A) Overheated and died

B) The fan motor died and the fan needs replacing.

It could just be the fan that has smoked, but i doubt it if you can smell a BBQ

if its a no name brand, then there might not be a temp control, most likely its burnt out
