A typical PC power supply has an enormous over kill on the 5 Volt supply. If you use the molex connector (such as used for 5 inch floppies) you should easily run an Orange pi one+ that draws 2 amperes. However, if you mount it inside the pc case cooling might become a concern.
If your pi has a better connection than the flimsy usb connectors, use it.

The Organization's schematic is incomplete, but it does show GLOBAL_EN connected to U2 - the PMIC (Power Management Integrated Circuit). Pulling GLOBAL_EN low (aka shorting to GND) resets the PMIC - which causes it to power up all its outputs, in turn causing the Pi 4 to boot - it's exactly the same as when you disconnect power, then re-connect it.
Your ...

I ran for pretty much five days straight with a CanaKit 3.5A PS. Not really overclocked or anything, but lots of streaming.
For the point of telling anyone who's looking for the answer, I was also running a HiFiBerry DAC+ (audio card) HAT with it, and the scripts for powering and the fan didn't conflict. I was worried about GPIO pin conflicts. I was ...

The Pi Zero has only ONE USB port.
The power connector might use a microUSB connector but it has no data pins, only power pins.
You can power the Pi via either port (this is not true of normal Pi).

A little instruction for people who want to resolder MXL7704-R3.
Order in aliexpress MXL7704-R3 (2.5$ - 3.5$).
You must have hot air rework station which can heat up to 350 degrees Celsius to remove the chip.
You must have soldering iron, flux, and tin. Voltmeter.
How do you know that you really have a breakdown of this chip? Connect 5 volts of power (the ...

If the undervoltage warning is displayed the Pi is not getting the correct voltage. In fact it only shows when the voltage is well below the USB minimum.
The current rating of the supply is largely irrelevant, and the many posts on this site are uninformed. Only poor supplies are incapable of delivering the rated current.
Incidentally the Foundation DOES NOT ...

Raspberry Pi 4 specs indicate that a 3 amp power supply is required, or possibly 2.5 amps if all connected usb downstream devices require less than 500 mA.

"I know the usb-c connector on the Pi is safer because of onboard regulators/fuses" then you know wrong!
The Pi4 has NO fuses and the regulator is used to supply lower voltages derived from the 5V input. There is no 5V regulator.
Indeed the USB-C 5V is directly connected to the 5V pins on the expansion header, so there is no need to (or benefit ...
