hello everyone
this internal power supply of creative inspire t6300 .no output power here so i want to bypass this power supply. if i know output of this board then i buy a same voltage and current rating adapter

thanks

 

Easy to measure the voltage. Current would be more difficult since it varies with the audio being played. If you know the max power output, you can estimate it. If the amp is type D, the current will be close to P / V. If AB, maybe 50% higher.

This board is totally damaged .i know only input power 100~240 ~50/60Hz current 600-350mA

 

Not so easy to measure the voltage if there's no power output. From the Power Adapters page on the Creative website it seems that their designs favour 12 - 15V, so as an informed guess try 15V at about 4 or 5 amps.

But it is AC voltage or DC voltage ?

 

Should be DC, the four diodes on the top left look like rectifier to me, you can check their connection.

thanks for reply sir

 

Did you look for markings on the amplifier board? Often they will label the input voltage.

What you have so far are GUESSES!!
What can be simply verified is that the output is indeed a DC voltage, because one pin of the output connector is marked as positive.
For an additional clue, the TS can look at the voltage ratings of those three capacitors closest to the output connector. The voltage will not be greater than that.
Measuring the output voltage of a dead power supply is not likely to provide any useful information.

They are two separate card inside them , this card only for power but don’t know voltage and current, I already connected with computer smps 12 v dc , it is working but sound crack

To a certain extent that is a guess too...

@vipul, they meant see if there is any marking on the board that was taking power supply from this board, or the other end of the cable that was in that white connector.

Just they write on external board only. DC in

 

Tell us the markings of the electrolytic capacitors by the bottom of image, and the markings on that 3 pin black part next to the output, and on the heat sinked bottom left.

Dear sir
There are 2 capacitors closest the out put . 1 capacitor is 25v 1000uf and second capacitor is 25v 470 uf .

 

I would feel safe trying first a 12VDC 3A wall adapter. Respect polarity.

Thanks for suggestions,
I did try with CPU’s smps 12 v dc but sound crack too much

May I use 24v dc 2amp and check again ?

No.
I suspect that the power supply required is 12 VDC for Creative Inspire T6300 PC amplifier.
You would need at least 5 A @ 12 VDC. Try this first before going to a higher voltage.
A 12 V lead acid battery will tell you if this is the correct voltage.

Dear sir
Thanks for reply ,
I asked about voltage and current by mail so they send me just inputs voltage
