|Power supplies are REQUIRED by the FCC, in the US, to have adequate filtering at the power line connection, and the power supply CASE must be shielded, as well as proper ferrite cores on the various leads to cut down radiation on the DC leads.|
Now, one question---Do you have your computer properly installed, in an approved case, with ALL the shields in place, including the factory shields over the empty drive bays, the unused card slots?
Do you have an (illegal) case with a big 'ol huge winder in the side you you can "see?"
Do you have the case assembled?
If all the above is in place, I'd be for either getting a replacement supply, or else even a different brand.
I'm a radio amateur, and am constantly bombarded, in this day, with radiation from every thing imaginable on HF radio.
Lamp dimmers, cell phone chargers, HP printer supplies, laptop supplies, routers, cable modems, and even one of my monitors when it is plugged in, but shut off.
TV sets, even processors in kitchen ranges and microwave ovens, can radiate interferance. Of course there are street lights, flourescent, and othe arc-discharge lamps. The infuriating Christmas tree blinkers make noise, and so do some solid state furnace controllers.
If you have radiated noise bad enough to get into a TV, it's bad. I'd be for getting rid of that supply. It's even possible that it has some electrical problem that could lead to more serious troubles.
