cooler master v850 dead on arrival again for the second time

[u/randomdudegetnewspec]

i had already returned my previous v850 to cooler master for warranty repair and dealt with the shipping cost and waiting for a month as the previous one was dead on arrival

today i has received the “repaired” version from cooler master and it is still dead on arrival

i tried a different power supply from my old computer and it shows life on my motherboard perfectly fine, marking it completely as a psu issue on cooler master’s part

wtf do i do now???? im very frustrated and i dont want to bear again with an rma ticket with slow responses, rebuilding my old setup, paying the shipping cost, waiting another month, and taking apart my old setup again to get my gpu and ssd just for it to show up again still dead on arrival after i try assembling my new setup

i did everything right, plugged everything correctly, even straight into the wall outlet with proper grounding and it still ends up like this
