Dual PSU Rig issue - 2nd PSU Video cards do not autodetect after reboot

[JohnWave]

Hello there!

So I recently added a 2nd PSU to my rig in order to be able to add an additional video card.

After any reboot, I literally have to scan for new hardware in order for additional card to show up. Is there anyway to make this auto detect or force scan new hardware after a reboot?

My hardware specs are:

     Asus Prim Z270-P Motherboard
     Celeron CPU
     16GB RAM
     2540GB SSD
     1500 Thermaltake PSU with (4) EVGA 1080tis on it
     750W Thermaltake PSU with (1) EVGA 1080tis on it
     (1) PSU Jumper cable connecting both PSU to the Motherboard


Everything is stable about the rig *except* for auto detect of the 5th video card.

I just want to avoid having to manually scan for HW to bring up the 5th card...

Thank you in advance!

Sooo many questions.

First windows 10 for os?

Second what are your tdp settings for the gpus?

Ah!

Windows 10 Professional

All settings are factory default - I did not tweak anything.

It shouldn't disappear, I'm on dual PSU mining with no issues. Try checking the voltages of the second PSU with multimeter, it might drop too low and cause the card to go unstable.
Also, try wiping the driver using DDU. Latest BIOS is also useful. Above 4G enabled and PCI-E set to gen1 is also required.

Check if risers are connected properly sometimes they can move and not work.
After adding each card its recommended to re-install drivers.
