Anybody can help me out..
I have 5 12GPU rigs ,
1 of them i keep frying mobo's .. i have tried everything..
Tested all parts sperately all seems to work
however the minute i attach my PSU's to the motherwboard whilst I have GPU's and risers powered , even without plugging the PCI's in the MOBO.
It instantly fries my mobo...
I have fried 4 motherboards already trying to trial and error...
it used to work before though...

Why would you attach PSU's while the system is powered?
Maybe I'm not understanding something. Can you give more info?
You missunderstand or i explained wrong :d
Either either way..
I tested all parts separate by powering the parts with psu. All fans are running etc .
However if I prepare my system.
Combine all parts like they should.
The moment I power on. It will fry the mobo. The cpu fan will spin briefly and it is dead from this moment.
I have fried 4 mobos already cause i don't know how I can find problem without trying to connect it.
Is it possible a gpu is dead or something? It used to work before and suddenly it died after I had some gpu losses..
If it is this gpu or a extender how do I find it because If i have all gpu powered with psu no mobo and no display. Just power to see fans running all have working fans.
How is it possible that broken gpu fry my motherboards? Or is it something I'm missing
how are you switching on your other/s power supply ?
Using this ? https://www.amazon.com/Supply-Adapter-Connector-Triple-Multiple/dp/B073PRM7YZ
Manually ?
Something else ?
Yes I use those.
However I have 4 systems still running like that.
Today I tested with a mobo with 6gpu card only.
It still fried, I also did not use the adapter for this test and it still fried my mobo.
I also tested
Also
I even fried a mobo while only the following where connected.
Connected on psu: hdd, pci extenders, 6pin gpu powers, mobo main plug +cpu.
Connected on mobo cpu + main mobo power.
The extenders were not plugged in.
This gives me reason to think it is not gpu?
Is it possible something gives short circuit? From psu?
it can be a lot of things but I would replace that psu. What brand and model is it?
on this particular system it are 2 different psu , on the other's it's 3 PSU all the same
The malfunction system has a 1200 platinum seasonic psu and a corsair platinum 850 w psu
The othersystems all have 3 x 850w corsair platinum psu hxi or something
how do i sample test this psu to see for error?
can i use voltage meter?
Im pretty sure you are going to see the right amount of volts unless you put some load onto it and what you are looking for is amp anyway (pure speculation, check with a pro).
You checked all your wires one by one carefully ? A short could definitely fry your motherboard but so is a power supply with a defect ovp/ocp.
