I have a strip with 150 LEDs (5v - SK9822) and I am running them from a switched power supply (connected at each end). However, 1 person in the household can hear an annoying power supply whine when it is driving the LEDs hard. So - does anyone with bat-like hearing have a recommendation for a 10A (or higher) power supply that does not do this? My 'current' one is branded LEADSTAR.
