[QUOTE="2BitSculptor, post: 934607, member: 65661"] I had to do a quick replacement of the PSU in my main HTPC. I installed a 430w Antec with a 120 mm fan to replace a Thermaltake 500w that was becoming increasingly unstable (power spikes) .. at least that's what the MoBo reported. But now the system has a high pitched whine that is noticeable when the audio is turned down, but is not fan noise. It's odd, but if I should hold the CPU fan still, the whine goes away after a second or two (not immediately). The load on the system is a 64w CPU, 5 SATA HDDs, an IDE HDD and DVD drive, and a single analog tuner.. There are also 3 USB powered units: IR and RF transceivers, and a PCtoTV video convertor.
