power supply fuse blows when turn on switch

[psatish1264]

Hi Everyone,
Please anyone help me on this,whenever i try to turn ON my power supply the fuse blows and i'm not able to figure out faulty region.

it may be due to short or or due to reasoon that ur current is exceeding then limit of fuse. but show me circuit

I'm afraid help is impossible without a schematic. Anyway, it may well be a physical thing, like stray shrapnel short-circuiting on your PCB or a hundred other things. Will you post more information? Otherwise you're kind of on your own...

Hi Zia and TonyM,

Thanks for your replies, right now i don't have schematics i will send it tomorrow.

Can you please send me some probable reasons why it blows, in generally.

No. So far, we don't even know what kind of power supply it is, or what it's connected to.

(I prefer to answer for myself myself, thanks to others for trying to though.) I'm afraid I can't, too many possibilities with too little to go on.

Correct answer for your question is overcurrent on some part of circuit and fuse melt or blow rapidly with some sound effect. Answer is based on your question details. You didnt specify what type of PSU, circuit, connected load,.... ;-)

Try to give us circuit, photo,...
