Im using VER003 (green PCB) and VER006 (black PCB) for all my builds .

VER003 arrived with 24 inch blue USB cable
VER006 with 20 inch black USB cable

VER003 have a M193 G1084-33 voltage regulator
VER006 have a FS1084 voltage regulator

Both regulators have On-chip thermal shutdown protection( provides protection against any combination of overload and ambient temperature that would create excessive junction temperature )

In the past few months i had to replace only one riser ( VER 006 ) , i had no time to check what was the problem , maybe just a USB cable .
