PSU Click Sound

[RMSH]

Hi,

last month I brought Computer everything runs normal while using so when I shut down my computer I get a click sound sometimes from my psu .
Does anyone can resolve my doubt.
Thanks in advance.
My config :

1. Z490 e strix gaming
2. I7 10700k
3. 1x16gb gskill trident z 3200 MHz ram
4. Samsung 970 evo 500gb ssd
5. Thermaltake Grand rgb 750w Gold PSU

Some PSU's have a relay inside that physically cuts the power when the unit is shut down, it is probably that.

If it's a click then it is likely the 5VSB relay.

When a PC is shut down the PSU is in a standby mode where it still provides 5V to the system to keep the motherboard powered so it's ready to turn on and keeps its settings (without relying on the onboard battery) and also power USB devices in standby. This 5V is provided by the 5VSB, which is like a smaller separate power supply within the PSU that only provides +5V. The click you hear when you shut down is likely as it switches between regular operation and switches in to 5VSB mode. Normal, and something a lot of PSUs do.

thanks, Is the PSU Listed a good one ? because My friend has suggested me to take this one instead of RM750 and also it costs a bit higher compared to RM750 here in india

I don't know why people are confused when they hear a click sound from their PC when they turn it on and off.

My TV clicks when I turn it on.  I didn't call LG.

My coffee maker clicks when I start a pot.  I didn't call Cuisinart.

Because that click is scary loud.

 

Entertainment electronics usually don't make such sounds at startup/shutdown.

Old TVs and VCRs aside, I do not remember ever hearing clicks that loud with consoles, laptops, mobiles, etc.

And it's not like I grew up in the 2010s. I've seen all kinds of stuff in my lifetime, growing up in a household that had a black and white TV.

None of my TVs / monitors do that. What is it that makes a click inside your TV? (not sarcarstic, genuinely curious)

Your TVs when "soft off"?  I have a 43" LG Plasma.  We keep it "soft off" (it's in standby).  When you press the ON on the remote, it goes "CLICK".

 

Maybe because it uses a lot of power.  Almost any time you have something that goes from standby to "on" and uses a good deal of power, you want a relay in place.

 

An old black and white wouldn't do that because you can't put an old black and white in standby.

I was like 5-6 years old when my parents got rid of it, don't remember much. But what I know for sure, is that it didn't have a remote, to turn it on and off you had to get up and press a loud, poorly stabilized, clicky button that felt cheap as freak lol

Ooh!  Actually I do know of an old TV with a loud click.  My grandmother had an old Zenith Space Command TV in the bedroom we would stay in.   It actually used audible signals from the remote to turn on, off, change channel, increase volume, etc.

 

It used used hammers hitting aluminium rods within the remote.   They were supposed to be higher than human hearing tones, but as kids we could definitely hear them.
