Help - Mac Mini cross interference

[For The Love of Music]

Hello

I put in a new Mac Mini to act as my NAS.

There are two dedicated sets of outlets, PS Audio, installed and grounded correctly and fed by a dedicated 20amp circuit.

The left outlet has a Niagara 5000 conditioner plugged in to support the 2 Channel and HT systems.

The right outlet has a power strip that supports control 4, Apple TV, Apple Time Capsule Router, 2 computer fans, Pioneer Plasma and the Mac Mini.

When I turned on the Mac Mini and Pioneer plasma to set the computer up, the Niagara started internally cycling. Note: Both are on separate outlets, and the main system was OFF.

I HDMI plugged the Mac into Video 3 and Video 2 is for the main display for all else. Then I reversed 3 and 2, same problem. When I switched videos not displaying the Mac Mini, the problem went away.

I then off the Niagara conditioner and had no problems setting things up.

In the end:

- Is it an internal grounding problem with the Mac Mini?
- Any thoughts on other?
