some day ago i got a problem in my zcash rig, only 1vga showing from total 4vga, can't showing my 3vga, trying to check anything, any cable its woking perfect, then im trying to put my vga directly on motherboard not using pcie riser, and the vga normally working perfect.
so im check the power supply and i found this

1 of my pcie (sata pin connector) get charred and brokken after i force to take the cable, and the cable is burned out.
im still happy other pin stil working perfect.

for all miner i recomendation some instruction :
1. dont use 1 pin cable for supply more than 2 sata pcie riser
2. don't use low power supply to supply pcie riser, even if you use other big power supply to give power vga.

Thanks
