i want to power a 3 raspbery pi zero from ATX power supply can i ? Answered

Hello guys, i hope everyone doing good,
I have this question, i want to power up a raspberry pi zero from ATX power supply (standerd power supply for computer)
i have search online for answer but, i don't have clear vision, someone told me to power the raspberry from the purple wire (5V 2A)
but i want to power more than one pi,
so should i go with red wire ?
red wire (5v 30amps), will the 30 amps kill my raspberry ?
or the pi will just take 1 or 2 amps from the 30amps ?
what should i do ?

and sorry for my poor english, god bless you all.

You might need to check first how to use the ATX as a normal power supply.
Ususally you need to add some ballast like a break light to the 5V rail, otherwise the power supply won't turn on.
Apart from that there should be no problems for your PI.

thank you sir for you replay, i have this power supply, and i mode it like this,

the red wire 5 volt

the yellow 12 volt

and orange 3.3 volt

so i have to add a break light to red wire [5v] to make it awake and runnig

then i have to use another 5 volt wire to power up the raspberry, right ?

The supply will work, the Pi will draw only what it needs, providing you keep the input voltage correct.
