The coil can feed back some RF into the mains, but normal PC PSU's should 
be able to cope with that. Depends on the TC power level, anyway ;-)

If you want some protection, add a good quality mains RF filter to your TC, 
and one to the other end where it plugs into the outlet.

However, if the TC is located close to any other mains cabling, some RF 
will couple directly into those cables and bypass the filters, even more if 
the TC RF ground isn't so good... Same RF coupling is true for low voltage 
cables on the PC - keyboard, mouse, monitor, etc, something on the 
motherboard can fry on overvoltage, or the LCD/TFT monitor be 'adversely 
affected' ;-)   => keep TC away far (enough) from PC

cheers,
