I was wondering what the effect would have on my toy home made amplifier by adding a 10400uF 16 volt capacitor to the 5 volt power supply thats powering my small amplifier?
is there any advantage? or should I use the capacitors for something else?
I found the capacitor on an old motherboard so i took it off and tested it and it works perfectly. but i wanted to use it for something that i have.. like my power supply.
at the moment the capacitor is safely discharged completely.
i'm wanting to put it in parallel with my 5 volt DC adapter power supply.
would it have any noticeable effects on my audio amplifier?

Nope : the energy stored in a capacitor is expressed in Joule
The amplifier may request less or the same amount of energy
which is related to output power ( musical peaks )
and usually 10000 uF is for 50 W of Output RMS power .

It might do nothing. It might increase buzz. It might reduce ripple. It might make your transformer run slightly hotter.
my amplifier does not contain a transformer anywhere in the circuit
and there is no buzz when you touch the input cord like the noise most amplifiers make.
in fact the speaker is silent unless I have music playing through it...
no background static or buzz or hiss whatsoever. even when its right up to my ear there is nothing at all.. but i can hear the music just fine when i play music or something.
would the capacitor do anything to the amps coming from my power supply? (power supply is DC 5 volts not AC) or am i wasting my time asking here?

I meant the power transformer. If you are using an SMPS then that is different.
The capacitor will do nothing to the DC amps coming from your power supply. Its effect on AC would depend on the details of your amp and power supply so you have supplied insufficient detail for an answer to your question.

Hi,
It will reduce the inherent ripple from a cheap 12VDC 2A wall wart.
It will reduce hum as your amplifier has a poor PSRR figure.
Its best added to the amplifier after the DC input socket.

With SMPS power supply, a huge cap like this may be detrimental to the PSU.
I would go with CRCRCRCRC supply. SMPS will be noisy so CRC with small caps and smalll resistors will filter out any noise.

My amplifier doesn't have any noise or hum that you speak of. 😵 and that's without the capacitor..
