Is it Possible to trigger gaming pcs power button when raspberry pi loses and gains power?
February 10, 2024, 23:38
I am building an arcade cabinet and I was wondering if I could have a raspberry pi hooked up to a power source that has a wireless outlet to remotely turn it off and on and make it power off and power on my pc when power is applied to it
Kind of a specific issue but i don’t really know where to start
Was thinking something like a Zero W so maybe I can wirelessly turn it off too
probably
i was more of looking on how to do it and not if it would work lol
like i mentioned in the description i dont really know where to start
ok first lets get onto turning on and off the pc
your button has two wires connecting it right?
ground and possitive, the button acts like a switch
The power supply in your gaming PC is probably a ATX compliant power supply.
But to be sure, check what brand and model you have!
And if it a ATX compliant power supply, then the power button is a logic level type (5 volt). The signal is either called "PS_ON" or "PWR_ON" or similar.
A note as the Raspberry Pi uses 3,3volt logic you need a transistor/MOSFET or level converter to level up the signal.
See: https://en.wikipedia.org/wiki/Power_supply_unit_(computer)
And why did I answer "probably" ? This is because you provided no "data" about your Gaming PC and I live by the rule https://www.youtube.com/watch?v=4CKiC6BO8hE

If you have atleast a motherboard
use motherboard pins to do that
Thanks for the ping
Just give me one sec to catch up
There should be 2 pins which will send power on/off signal to all of other parts in case they do a contact. Usually this two pins are conntected to a button
Right
Thats how i did my own wireless on/off application
That makes sense
Not really sure about volt
I used this
rather than conntecting it directly
it is a curcuit braker or smh like that
but can handle a lot of power
10 A at 220V
And that will allow me to connect it to the pins on the motherboard
but if you measure out the volt you can just connect it directly if it is under 3V ig
imo it is safer than messing with power suply directly
Yea exactly
That was more what I had in mind from the start
Also for the thing you asked in title
I would do a system where a script executed when rpi boots and script checks whatever it should have been on or off
But there is even a safer way
This thing has both SIGNAL ON-CONTACT and SIGNAL OFF-CONTACT
I did a wireless remote for cameras using ESP32 with this thing where when ESP32 shut downs and power goes out power-off and common cable contacts which makes electricity go and open cameras (since it is safer than letting them turn off)
You can check out, it is fairly cheap and easy to use. Has 3 cable screw place, NORMALLY ON, COMMON, NORMALLY OFF. NORMALLY ON means when signal is sent, this cable will no longer contact with COMMON cable
and on other hand it is reverse
it is normally off and doesn't contact COMMON, when signal is sent it now contacts COMMON
The only thing I can really think of is I think it’s 2 pins instead of 3 that trigger the power button maybe I’m just overthinking it though
I’m a little new to a lot of this stuff so I’m trying to make sense of it
what was that for?
the bot? it's for ok's site because otherwise the links are broken
<#1047463526043746304> is logged to a site online so people can Google it and solve the same problem in one of these threads. if you don't have a space after links for some reason they become broken
Also I wouldn’t of minded providing information if you just asked instead of giving me an extremely vague response at the time
Thank you
That is a isolated input, so it is safe to use TTL, no need for relays
Realized my mistake sorry abt that
Ok if that is your attitude...
Look don’t get me wrong I appreciate the help and all i just felt like if would have been easier if you were more direct than just saying “probably”. It’s not me trying to be rude
let's both take that as a learning opportunity
yea because it cant know otherwiese where the link starts and where it ends
makes sense
