Any way to power that https://templates.blakadder.com/oisentech_SANT-SUC01.html
from a usb port?
I am asking because I want to use this to control my mini itx J4105 itx board whose pciex1 is already occupied.

Alternatively, is there a way to attach a similar external wifi antenna bracket to a tasmota device which could serve the same purpose?
Namely, remote turning a pc on and off.

Well there are plenty of USB to PCI-e adaptors out there

Any esp32/8266 board should do the trick if you add a relay module or a FET to connect to the power_sw pins.  You could even add another relay/FET to connect to the reset pins and be able to control power and reset.

The PCIe board appears to only need PCIe for power.

I am not aware of any such devices, (usb to pcie).
Do you have any links?
There are plenty of the opposite kind (pcie to usb) but they are useless in that case.
I found some extension cables that provide pcie x1 port using m.2 slot and an additional power input such as molex or sata power.
But one would need an available m.2 connector for that.
I have such a connector, but its for wifi/bluetooth only as is the case with the motherboard where I want to use it.
I am afraid, it could damage the motherboard if used that way.
And besides I am not even sure, the 3.3v would be provided at the righ pin with such an adapter.

@Zeb, the main issue as far as I am concerned is the need to solder on an external antenna, since the computer case would act as a faraday cage.
Also, from the posts I could find, its rather tricky to solder on and requires pretty good skills with solder iron which I don't have.

Wow thanks.
Then I assume I would need to use something like:

?
And since it only requires 3.3v which I guess it will get from the first adapter I don't even need to plug in the extra power?

Well I don't know about that. It looks like the SANT-SUC01 just uses jumper wires for the on/off/reset but I presume it uses PCI-e for data transfer and I'm not sure why you need another USB/PCI-e.
You didn't explain the use case but, if you just want to power the PC on/off remotely, any ESP8266 device with a volt-free contact and jumpers to the motherboard will do that.
Real-VNC will let you read data and restart remotely without any hardware at all.
Finally, if the motherboard is set to reboot on connection of supply an ESP8266 with a changeover relay with the supply to the PC wired through the NC contact could be used to reboot a crashed PC by a 2 second blink of the relay.

I am pretty sure it doesnt use pcie for anything except power.
You can see that it hooks up to power button connection on the motherboard.
So I assume it does on for a couple of seconds to turn the device on or off.
It is possible that the pc status (on/off) is determined by one of pcie pins, but this is less relevant for my case.
Here is what I am trying to achieve.
I have a server which is hooked up to a ups.
The "server" is not really a server but a J4105 ITX motherboard with a bunch of ssds hooked up.
So when there is a long power outage the server naturally powers off.
I want the server to auto turn on when the mains voltage is back.
So I don't have to be present to turn it on.
Note that the use of motherboard setting to auto turn on after power loss doesn't apply here as the server goes of in an orderly manner, so it won't turn back on, when the power is back.
So I want to install tasmota on that device, and setup a startup rule to send a second/2 second power on/off sequence on the power pins.
It has to be a device like that with a bracket with wifi antenna atttached to it, since any other esp8266 device won't work due to server case blocking wifi operation.
So if the device you linked works, I will need to convert the mpcie it provides with mpcie to pciex1 which will power (hopefully) the tasmota device.
Does it make sense?

OK but I don’t even think you need the device (or wifi really) to do what you want.

All you actually need is a device which blips a volt-free contact a few seconds after the mains comes back on. It culd be an HW-655 powered by USB outside the cabinet. The NO contacts need a flying lead with DuPont connectors to the motherboard power switch button and then a rule

On system#boot do backlog delay 300;power1 1 endon

Pulsetime 5

Will give a 0.5 second blip on the power button of the PC

 

BTW my PC will boot on mains power returning even if it did an orderly shutdown. It’s actually how I switch it on because it’s difficult to get to.

You are right, I don't really need wifi, but if that comes with wifi, I figure why not have the option to perform remote shutdown?
You are also 100% on the money on the usb source being out of the cabinet (I plan on using a phone charger for that purpose and on a line thats not UPS backed so thats how I will know the power is back.
Regarding bios settings, unfortunately its not available with my motherboard (at least I am not aware of any such setting).
There is of course the standard restore after ac/power loss, but it doesnt do the job after an orderly shutdown from what I could observe).
