Guys, I have a system with 5 GPUs, 3 R9 290 and 2 RX 480, all using usb risers with sata/molex adapter. He's been standing about 3 months 24/7. Today I smelled something burnt and found what is in the picture. Just the two that energized the RX 480. Do the RX 480 continue to extract more than pci_ex can support? Is there something wrong with my PSU?
My RIG:
Asrosk H81 Pro BTC
Intel Celeron G1820
8GB RAM
3 R9 290 + 2 RX 480(all stock)
USB risers
Cougar GX 800 + Corsair CX 750

you need cooler cables.
try to lookup "mining cables"... they will come in cooler colors, black is the worse ones. try to find ones with all white cables.
put a fan pointed right at your cables until you fix this problem!
unless you have the blue cables like me, they are watercooled. no fan needed.
