I used to have an Icom 756-PRO III, using a PS-125...  Had it for 5
years, no noise increase, and my HF antenna is maybe 40 feet from the
PS...  I now have a Elecraft, and external PS, and went through a total
house cleaning to make sure I had no RFI, so I am very clear on the lack
of RFI from the PS-125...  See details of the house cleaning on RFI at:

Thanks and 73's,
