Hi! A week after I upgraded my psu to 600w, I noticed strange crackling noises coming from my 2.1 altec speaker system (not in the sub, but more on the L and R speakers). I happens whenever I play a movie or music (when it is silent, the speakers don't crackle). It's not a loud crackle that drowns the sound, but it is noticeably irritating.

Can anyone enumerate possible causes and fixes for this problem? I am using an integrated soundcard btw, so I don't know what the problem is.

Thanks!!!! :thumbsup:

Hi

If it only happened after you changed out the PSU it could be the new PSU.
Can you put the old one back to see if the crackles go away?

Why, how could the new PSU affect the crackles?

Still there.

It isn't loose speaker wiring either.

Hi

Are you saying that it still crackles with the old PSU?
It seems a bit of a coincidence that you only have this problem since you changed PSUs.
You say that you hear the crackles when playing music and DVDs. Are they playing from your optical drive, hard drive or both?
Have you checked all the PSU connections?

Sadly both optical drive (games) and hard drive files (movies and mp3s) are affected. But only when sounds are played.

Yes, I feel that the PSU upgrade is connected to the issue but I dont know where the problem lies.

Connections seem fine

Sounds like interference. Reroute the speaker wires away from power cables. Use a different outlet for the speakers and computer.Try keeping the speakers away from the computer as best as you can

May I ask what brand of power supply you went with?

No, there's nothing wrong with your speakers :thumbsup:.

Have you checked to see that other sound inputs are muted?

You said "crackling", that sounds like interference.

I just did an experiment with my onboard sound (on this system). When I play music and open another program or do anything else that's CPU-intensive on my system...I get a short, faint crackling (which is normal on this system, using the onboard sound).

I see two alternatives:

a. Invest in and install a separate soundcard...which will minimize CPU sensitivity.

b. Don't do anything else on your system when you want to do these activities.

The problem exists because you are using the onboard sound.

I wouldn't say it's impossible. If need be she could try them on another computer to see if she gets the same results

but if it is interference or anything magnetic, why didn't the crackle happen before the switch?

The psu is an imaster 600w. I am not familiar with the brand since my brother got it from Taiwan.

Obviously, not all power supplies are of the same quality. Your older PS might have been better insulated

Would an external sound card help solve the problem then?

Before i'd purchase anything, I would rule out all scenarios. I would definitely try the speakers on a different computer to rule out that the problem is the speakers themselves

Also when you replaced the stock power supply the wires are most likely not in the exact same place they were before, and may be causing some interference inside the computer.
