esp8266 Controlled ATX Power Supply

I'm a noob :D and i'd like to know if this build :

would be possible with just one esp8266 and no other arduino board attached ?

If yes how would you advise lowering the atx 5v stand by to 3.3v needed by esp8266 ?

I'd plan as well to add an esp8266 to each molex of the atx (minus the connector) then how would you advise the switch for the 5v and the 12v would this kind of other build be helpful ?

thanks in advance ;)

Of course, and the Esp can be even be programmed using the same language and IDE as an Arduino. Or you could program it with NodeMCU Lua which is even easier.

For example, with something like this:

You'll also need another curcuit (e.g. an optocoupler) to control the 'power on' line (the green wire) of the ATX supply.

I don't understand why you need more wifi modules. A single esp-12 might have enough GPIOs to switch all the 5V and 12V lines you need. But I don't think a board with a triac would be suitable for those DC voltages. Instead, you might want to use relay boards like this one:

Hope this helps.
