Magic smoke released from controller..

[shorza]

Hey all, I just upped my voltage from 83v to 95v and when i switched off the controller I noticed a puff of smoke come out of it.

It is a 18 FET Lyen Low RDS MOSFET Overclocker Ready controller. I opened it up and I am not sure if it is possible, but i think a capacitor vented and oozed a smelly liquid everywhere.

I would like to know:
What causes this, is 95v too high?
Can simply replace this capacitor?
Could this happen again?
Is something else likely to be damaged?

Thank you,
Chris

I have noticed the cap read 63v.

Do i need a 100v replacement? There is another cap the same size on the board, should that also be replaced?

Kinda odd that controller having a 63v cap in it. If you asked for a 60-90v controler, I'd be wanting to know why it had a 63v cap. Are all the caps same?

You ask for a 72v controller or a 48v controller?

Hey Dogman, thanks for the reply.

I contacted Lyen about this and he said that he must have left this 63v cap in by mistake. He has offered to send me a 470uF 100V cap free of charge.
I'm happy to buy another as i'm sure they are fairly cheap.

Would i be correct in saying that this cap should also be 100v?

There should be several caps that need replacing. All of the big ones for sure.
