Does noise from Laptop SMPS affects Differential Inputs Amplifier?

In my experience this style is more than good enough.

With ripple voltage out of the way, consider such value SMPS seems alright, however not sure of the build quality.

Would likely go for more commonly use Meanwell and a higher DC voltage. Thanks for your help on the Q&A.

Another consideration just come to mind as read-up SMPS.

Is there any need to consider SMPS having PFC over non-PFC?

As PFC SMPS compensate reactive power, used in inductive, motorized application, reduce harmonics, it was said to reduce THD,

So does it mean we should prefer SMPS having PFC for SQ?

Merry Christmas... anyone has any thought on this above matter?

I prefer PF corrected SMPSU yes. But I tend to ignore it on lower powered supplies, its more of an issue for supplies for power amps.
