You can use a standard ATX power supply (designed for PC's and small workstations) to power a Pi. It won't be through the MICRO-USB / USB-C, but rather via Pin 2 or 4 and any ground pin or suitable ground point (most metal shields, for instance) on a Pi.

Adding a polyfuse is suggested but not entirely necessary.

Just be sure to get the polarity correct and do not use the 12v wires (usually yellow), use the 5v wiring (usually red)

Also ... Pi4 does not need the full 3A for itself.
So if you are not planning to add power hungry USB peripherals to your Pi4 then lower power is fine.
See the specs for more detail.
