Hi you guys. I just got myself a new graphic card and SSD. I had an "old" HX 720W Corsair PSU from before. (which is actually good). I plugged every cable to the right place, also the USB for keyboard and stuff and suddenly it smells burned.

After this I can use a single 4 pin connector from the PSU, nor 3-pins connectors. Only some of the connections working, rest are fucked! And if I unplug every cable, the mobo, fans and all start up.

So I tried one more time with changing some pins to another pins. And suddenly smoke came out of the SATA 6/b connector, what the duck??? I immdiately pulled it out and turned of the pc. Mobo still working, but im guessing this is most likely the PSU thats dead?`It happened right after I plugged in the USB! It smelled burned from the PSU!

Help
