I have built 17 rigs successfully.......but this next rig....whoa.....what am I doing wrong?
I have fireworks and dont know why?
its a 12 gpu 570rx rig. I am using asus z270AR motherboard. I use all 7 pcie slots, both m.2 slots and a 3 card expansion board.
I have a coolmaster 1200 PSU hooked up with a evga1600 using a dual PSU adapter.
I have the first 4 cards, their risers, expander board and motherboard on the coolermaster 1200 psu. These first four cards run through the expander board. The expander board is powered from a molex off the same power supply(1200 coolermaster).
i have the next 8 cards, and their risers on the 1600.
I start it up and POP with smoke and spark. it was very loud and startling. i unplugged quickly
The pop came from a card that is plugged into the 1600 using a normal motherboard pcie slot. There could be other damage. I dont know. This card is powered by an 8 pin on top. This 8pin strand also powers a 6pin riser on another card above it..... which is also on the same power supply.
What am I doing wrong??!?!?
