MSI solves Nvidia GTX 200 squealing problem

Personally I just want to say, hurrah for MSI because it's a shame Nvidia didn't learn how to stop its GTX 200-series from making the coils inside a PSU squeal like a baby powered from a 230V source sooner.

After reporting the problem to Nvidia, we were greeted with denial - it was unable to replicate the problem - until we sent readouts from an oscilloscope, displaying the interference shooting back up the PCIe power connectors into the PSU.
