Plamo Posted October 22, 2010 Share Posted October 22, 2010 Hello all! I purchased a TX650 with a new system about two weeks ago, everything worked fine except that the power supply emitted an electronic kind of squeal. is an example of what this sounds like. Note that this is not my video. I RMA'd the power supply to NCIX(where I bought it), unfortunately the replacement has the same issue. At this point I called NCIX tech support, followed what they said, but no luck fixing it. List of things I have tried: Switching power cables/outlets/power bars Changing the M.I.T(?) voltage settings in the bios, the ram is now set to 1.65 instead of auto (at suggestion of the tech support agent). Removing Graphics Card-- same problem. Enabling vsync on the video card -- made no difference Paper-clip test: The first PSU seemed to pass this with no whines, but I have a feeling that this isn't entirely indicative of my problem. I can do it on the replacement if necessary. He also suggested pulling out the mother board and putting electrical tape over places where it contacts the case, suggesting that there might be a power leakage somewhere. I haven't done this yet, I'm hoping for an easier solution. The last thing he left me with is that the parts might just be simply incompatible, in which case I'll have to swap out the PSU/Mobo/GPU for something entirely different. Again, hoping for an easier solution. I ran speedfan, here are the results for the voltages: Vcore1: 0.93V Vcore2: 1.62V +3.3V: 3.36V +5V: 5.05V +12V: 2.11V -12V: 1.17V -5V: 8.58V +5V: 3.63V Vbat: 3.12V I'm hoping someone here will have a quick and easy fix for this. It's cost me $20 and ~2 weeks already to RMA the thing once, I'm a university student, and while I'm not quite the starving student some are, I don't really have extra cash to shell out shipping power supplies back and forth until I get one that works. If it comes down to it, is the inductor whine(assuming that's what it is) actually dangerous to my system, or just annoying? If it's just something that causes annoyance, I can probably put up with it until I can replace the power supply with a different model. Thanks a load for reading this, it turned into a bit of a wall of text! Link to comment Share on other sites More sharing options...
