ON/OFF switch

[Timast3r]

Hello everyone, my name is Tim and I have a question. I recently received my new prebuild since I’m too scared to build one myself. But I have one thing I’m unsure of. That is the ON/OFF switch, there are no problems with the switch, but when I turn off the pc, via the windows key, one tiny light is still shining from my GPU. But when I flip the power supply switch to OFF, it doesn’t appear anymore, which is logic ofcourse. But my question now is: Is it actually turned off? Because when I click my mouse it actually shows the RGB on it. While the fan in the pc is not spinning. So it’s not on.

 

ehhhh, help?

I find when I click my mouse while my pc is off, it flashes its colors. I think you should be good unless the gpu itself's fan is spinning.

Oh okay, thanks

@Timast3r The on/off switch on your power supply disconnects the power supply completely from your mains, so the computer receives absolutely no energy.

 

A  computer power supply is actually made out of two power supplies inside, one very tiny power supply which provides stand-by power and runs 24/7 even when you shut down the PC, and the actual power supply which is turned on when the computer actually runs.

 

The very tiny power supply that runs 24/7 is like your phone charger, it gives the PC up to around 10-15 watts.

 

The chipset on your motherboard is powered all the time using this power and waits for you to push the button in front of the case to turn on the PC by telling the power supply to turn on completely.

 

It can also use some of this power to send energy to some pci or pci-e slots, and to some USB connectors.  The idea is that you may want to turn on the computer by clicking a button on your mouse, or by sending a specially crafted packet of data to your ethernet card.

 

As another example, in the past there were computers with fax/modem cards and you could configure those cards to tell the bios to turn on the PC when the modem receives a call. This way by the 5th ring or so, the computer could be fully turned on or could wake up from "sleep" and accept a fax, save it to disk and go back to sleep and save power.

 

Modern motherboards also keep some USB ports powered with the idea that you may want to charge a phone or some devices without turning on the computer.

 

Motherboard also uses a bit of that power coming from the power supply to keep the time and maintain bios settings. The battery on your motherboard is not rechargeable, and it's used basically only when the computer doesn't receive stand-by power from the power supply, which is why it's a good idea to never turn off your pc completely (except when there's heavy storms with lightning strikes, or there's bad electric power in your area)

 

 

So that led on your motherboard is simply there as an indicator that it receives power.

Oh my, thank you for the explanation!
