Dedicated PSU??

wall -> ups -> powerstrip -> pc & devices

Yeah, that's the scenario I highlight above. :)

FWIW, I'm running a microATX board with an Athlon 2000, 1 7200rpm HDD, 2x120mm fans and a "200W" car amp (fused at 5A) from an Antec SL350. With the computer running and music playing louder than I'd ever want it, the 12V line still stayed rock solid at 12.02 - 12.04V. It has 16A on the 12V line.

By comparison, a Macase 250W PSU with 10A on the 12V line sat at 11V with nothing but the amp connected, and the amps caution light lit with every beat.

The only downside to my current configuration is there's a lot of PC noise coming through, either memory or HDD generated. It's not power based, as using a discman as a source sounds clear and quiet. Contrastingly putting the PC's sound output into a stereo is also clean. Strange.
