Problems with coil whine indicate a possible issue in the speaker's motor or wiring.

It really doesn't help much, though many 6950XTs are sensitive to coil whine. I’d suggest a 750W PSU is probably too low for that model—aim for at least 850W, but it’s unlikely to stop the whine entirely.
It's just an approximation. It looks like your PSU might struggle to provide power for the 6950XT, even if the PSU has some coil whine issues. You should look for a PSU without any obvious coil whine, though the GPU can still vary slightly when switching PSUs. Most 6950XTs mainly experience coil whine in different ways.
