Hi @DarkAvarian, very good nice documentation, CPU power plug is definitely in, and various confirmation to questions by others....

I'm out of ideas, last of last, borrow another CPU from a friend? or a shop? to try???

Hey cx5,

yeah that was why i started this Post, as i am out of Ideas too ;(.

Still thanks for your time! Will try to look where the problem is, when my next order arrives tomorrow and give you guys a short feedback here.

That darn thing is still insulting me by glowing red like its in full function, while its complete out of order and doesn't even start ;(

okay i have mostly figured out what is wrong, thing is, ALL our PSU got an 24pin for MB, 2x4pin for CPU and multiple 6+2 pins for PCI-E ... our boards need 24pin for MB AND 3 times 4pin CPU, so i, dumb as i am, used that 6+2 pin PCI-E as it FITS perfectly in and used 1 of those 4pin for CPU to get it done... and as far as it is, PCI-E works same with 12v but that cable order is not the same as CPU thats why its not working... at least that is my biggest guess... if someone could definetly agree to that, id be veeery grateful xD

Hi @DarkAvarian

The CPU and GPU power plugs cannot fit each other normally.

https://www.google.com/search?q=cpu+power+pin+layout&newwindow=1&sxsrf=ALeKk03bjyX0UC1u3ZrzUBnuIzLXVL5EQA:1608173119645&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjalaLc_9PtAhV7w4sBHQxmB1EQ_AUoAXoECBAQAw&biw=1313&bih=670

But you're right, they cannot be mixed up. The pin layout is different, if force fit I think the CPU and GPU would explode, as the picture shows 12V+ and GND reserved between the two plugs.

OK, I just checked your PSU and has molex sockets too, hence please double check not to mix up CPU and GPU or anything thing. Although they are POKA-YOKE, impossible to plug wrongly.

and I want to introduce a different problem, post error code = 33, 7b, 6a, 66 and repeat. clear cmos does not work in my instance,

1) got to remove SSD, GPU,
2) then clear cmos without SSD and GPU
3) install GPU without SSD
4) must boot once and post pass showing no ssd found
5) reinstall SSD then all OK.

so may be you can try clear CMOS without anything, no ram, no cpu, no GPU, no SSD, no fans, etc.
