How to keep a power supply running connected to a PC and a Miner?

I think were all pretty much on same page that this is not easily going to happen.

What miner are you going to run, and why are you not wanting to use secondary PSU so bad?

The only way would be philips idea.

Other than that I believe it is pin 16 + either 17 or 18 for the PSU to be powered on, how you can get that past the motherboard is a different challenge.

What would happen if the PS power-on trick jumper pins were connected at the cable level?

So it is plugged into a motherboard but the power on wires are connected constantly?

I also read somewhere about some person using a resistor to do the same across those wires with success.

Resistor/switch/paperclip are are essentially the same.  And they all work.

On plugging in to computer I would think computer would be powered on and just stay on with just the power jumped.  Look at  philipma1957's he did a good job of showing what needs to be on a switch if you wanted to do this.

The biggest outstanding question is- "What miner are you trying to power?" Why would it matter?- well simply put- Some of the newest spec PSU's on the market today DO HAVE the Ability to allow the PC to be OFF while still sending Power to Charge a USB Device. The available amperage is low, 2amps or less. I'm not aware of any Current Mining Hardware that can operate as a Stand Alone Miner with this power scheme.

Since most miners draw quite a bit more than that, I think that's a moot point. I've given up on doing this directly. I'll try it again as I have time through BIoS/Software instead.

It was more of an idea to see if there is a way to get a PC backup running if someone tells it to shut down more or less. The question with the Miner was just a bonus.

A PSU with USB bypass power feature directed to a Raspi, with its own network connection and a skit to GPIO that mimics the momentary on/off switch from your front case could work for bringing up a PC that's in the Off state from a remote connection to your network.
This would be if you were trying to find an alternative to using the wake on LAN option provided by Windows.

What you could try is setting your PC to hibernate/sleep instead of power off.  It will use minimal power at that point and is probably your best option.  Most real solutions will cost more than buying a second power supply for the miner.
