The WireView Pro GPU is a device for measuring the power consumption of graphics cards. As a Pro version, it is also equipped with connector detection, temperature sensors, and an audible alarm. The measured data is displayed on an OLED screen. The Pro version has been upgraded with connector detection, temperature sensors, and an audible warning signal. The WireView Pro GPU's connector detection identifies whether a 150-watt, 300-watt, 450-watt, or 600-watt specified cable is used. The WireView Pro GPU is available with the 12VHPWR 16-pin power connector (4x sensor + 12x power/ground) in "Normal" (N) and "Reverse" (R) versions: If the graphics card has power connectors where the four sensor pins are located between the PCB and the 12 power pins, the "N" version is required (PCB - 4x sensor pin - 12x power pins). If the graphics card has power connectors where the 12 power pins are located between the PCB and the four sensor pins, the "R" version is required (PCB - 12x power pins - 4x sensor pin). Note: When using the 12VHPWR adapter, ensure that each of the three or four 8-pin PCIe connectors is connected to the power supply via a separate 8-pin PCIe cable. Using splitters (Y-cables) is strongly discouraged! Warning - Important Notice: Risk of Injury! Depending on the graphics card used, particularly in the case of the GeForce RTX 4090, up to 450 watts of power can flow through the connectors of the WireView. This heat can cause the PCB at the WireView connector to heat up to 60 degrees Celsius with an air-cooled graphics card. In the case of a water-cooled card without airflow, the WireView PCB can heat up to 100 degrees Celsius! The WireView casing should not be touched during operation. After shutting down the system, allow the WireView to cool before handling.
