Ouch! That hurts to even look at!

If you think a controller melt looks bad, you should see the hash boards when they melt... Cry

I smoked an S7 controller with a mis-wired PCIe connector (+ and - reversed). Burned up a couple of the voltage regulators, but is probably repairable and nothing happend to the PSU and wires. Yours looks to be much worse...

Do you think I could still splice the one burnt pcie and keep using the power supply?

I wish I didn't have to ask this question, but to what extent could this board have been damaged by reversing the 6-pin pcie power connection? Also, do you think the psu is toast or could it be salvaged by splicing the pcie?
