This noise and also EM noise are the most common design flaws in those. Electrical noise in the air conditioning high-voltage line, such as A "switching" power supply (like virtually all modern computer power supplies) works by "rectifying" the incoming 120V 60Hz (in the US) AC power into DC (at around 170 volts), "filtering" with capacitors, then using a semiconductor circuit to "chop" the DC voltage around 1000 times a second to turn it back into crude AC. The PC is running just fine. I turned off the switch and unplugged the kettle plug. The issue is the lower voltage might still be too high for the UPS to switch over but low enough to cause a In the video you showed, it sounds like the fan could be hitting something or a bad fan bearing. Upvote 0 Downvote. The electricity didn't cut when that happened. I listened while the cover was removed, and it appears to emanate from, or very near, a component labeled TF-2715 (a transformer?). This is caused mainly when the input power is dirty/ distorted. I'm thinking of replacing the power supply but I want to make sure it will fix the problem and im not wasting my time. The power supply must also be able to provide a reserve of power to cope with any sharp transients in current demand without suffering a decrease in voltage output. P This is from the Corsair SF Series SF450 PSU. Can That clicking would be the switching circuitry turning on and off sharply, imo. Most often, your power supply starts making a weird noisewhen you first turn it on instead of just making a noise as you use your computer.
