agreed, silver is not a good option for anything, in my opinion. That being said, if you are looking for internal wiring (inside the power strip) to connect the actual outlets, Tempo Electric sells solid-core silver wire even at 12awg and 10awg sizes:

If you are looking for a power cord, there are probably a few out there. A couple I do know about are Wire World Platinum Electra and Purist Audio Design Diamond Limited Edition.
