Sony Viao - the only noisy PSU?

[Stever750]

Well it burbles away through a DACmagic+, and the Chord Qute on USB, despite grounding both devices via the amp. Unplug the PSU, and silence! Is this the only lappy to make such an horrendous racket when on mains? It's plugged into a Tacima block, so it has a fighting chance.

 

Incidentally, USB playback through a NAD C390DD is silent.....

Yes Sony Vaio supplies are the noisy ones particularly from 2010. Not much of a choice but to throw the old ones in the trash and the newer 19v slim designs are dead silent, and cute the noise.

Thanks for the advice - how can you distinguish between the two? I'd get a new one today if I was sure it was a new silent one!

I've got a 2010 model, just ordered a new Sony PSU from Amazon, they are differenet in appearance (slimmer) and rates at 19.5V so presume that's the newer one.

I build my own computers, but this company makes PSUs compatible with Dell and other major manufacturers. The PSU is dead quiet.

Quiet case fans and especially CPU after market coolers make a big difference as well.

Well, sorry but the advice to buy a new PSU was a £25 bum steer, no better than the original fat one that came with the machine when I bought it in 2010. It's so bad in renders the USB connection on an Audiolab M-DAC unusable.

 

The answer is actually one of these:
