Cool, thank you for clarifying! After just removing cables from the unit I figured that it came from something powering the mobo, I'm assuming it's either from the memory or the USB hub for the RGB.

So it seems that the buzzing noise from the PSU when the PC is completely off could come from other peripherals or devices still being connected and powered by the 5V? Keep in mind I’m asking when the PC is completely shutdown, not in something like sleep mode, as the buzzing only happens there

Ahh, okay. So even though my PC is off, things like my keyboard and mouse can technically still be on? Though I don’t believe I have anything related to wake on to warrent that (I’m assuming what you mean by wake on is things like using your mouse or keyboard to wake the computer. I will say I do have an XMP loaded onto my memory, so would that be an example like you stated? And based on what you’re saying, it seems that the faint buzzing noise is a result of this? So it’s intended?

Apologies for not making it so clear, edited original post as such to better specify. My question concerns on how the PSU does the buzzing noise when the PC is off but the PSU is on (I thought this state was called standby, correct me if I'm wrong). I was wondering if that was normal for the PSU to keep buzzing like that (I know technically it's still "on", but from other manufactuer PSUs such as EVGA, I've never heard these noises before when the PSU is on but the PC is off. I unplugged my usb headers and such to see if anything connected was the issue, and the noise seems to still persist. Hopefully that makes it more clear. That being said, the information about how plugging in different powered devices can actually make your PSU more audible was interesting. I’ll definitely keep a mental note on that.

Hey, I recently build a PC and bought a new Rmx 750w. However, I noticed very faint buzzing from the PSU when the PSU is on standby (PC is off but PSU is still on). Granted, this is very faint: I didn't even notice it until I was basically hugging the PSU to my ear (I'll post a video when I can, because it's nowhere near as bad as what others had). Nothing out of the ordinary anywhere else, and even when the PC is on sleep mode the PSU is basically dead silent and I can't hear the slight buzzing. Is this just normal for the PSU? Been looking at other forums and people discussing similar issues but I see conflicting messages or they have much worse issues than I do. I have used other PSUs in the past that didn't buzz when on standby. Edit: Here's a video showcasing the buzz. It's very faint but it's there [ame] [/ame]
