hi, i recently bought an asus eee box which is a small form factor pc that is fed into a usb dack in my hifi rack. unfortunately, the wall wart (switching) ps that it came with (same ones used on laptops) is giving off a lot of noise pollution on the ac line and audibile through my speakers. i have it plugged into a balanced isolation transformer which helps a bit, but its still noisy. im looking for suggestions on what i can replace this with no ill effects on the pc. when i had my squeexebox and bolders linear power supply, the noise was very quiet. im looking for something similar although at a cheaper price point. any suggestions would be appreciated.
p.s. the wall wart specs are as follows:
ASUS AC/DC ADAPTOR
Model: SADP-65KB B
Input: 100v-240v --- 1.5A (50-60 Hz)
Output: 19v --- 3.42A
