The WireView Pro II is a device for measuring the power consumption of graphics cards. The 2nd Pro generation offers additional monitoring features in the form of per-pin power measurement, as well as an extended warranty and a TFT-IPS display.

Important Information on Compatibility Checking!
Before purchasing a WireView Pro II, it should be verified whether the graphics card in use is compatible. To do so, the following steps can be carried out:

1. Check the compatibility list in the download section of the product page. The compatibility list is designed based on a horizontal installation of the graphics card with the power cable routed toward the bottom of the case.
2. Using the technical drawing in the image section of the product page, check whether the WireView Pro II is compatible with the graphics card, the case (clearances to the side panel, etc.), and, if applicable, the CPU cooler.
   The WireView Pro II is available in two variants. The choice of variant primarily depends on the routing of the power cable from the power supply, as the display on the WireView Pro II can be rotated by 180° in the settings.

Depending on the orientation of the 12VHWPR or 12V-2x6 connector on the graphics card, either the “Normal (N)” or the “Reversed (R)” variant is required to route the power cable toward the graphics card cooler. The description assumes a horizontal installation of the graphics card with the power cable routed toward the bottom of the case.

The WireView Pro II has been specifically developed for the demanding use of modern high-end graphics cards with the 12V-2x6 connector and represents the most advanced iteration of the WireView Pro. As a patented development by Thermal Grizzly, it is protected by European patent EP4250057. Current is not only measured as a total value, but also per each individual pin and wire of the 12V-2x6 connector. This enables immediate identification of potential contact issues between the cable and graphics card. The WireView Pro II has been purpose-built to enable precise monitoring of the 12V-2x6 connector, allowing early detection of load distribution problems and helping to prevent possible damage to the graphics card and the 12V-2x6 connector.

Monitoring
All safety-relevant parameters such as currents (A), voltages (V), temperatures (°C), and power consumption (W) are continuously measured. Thermal Grizzly has defined threshold values which should not be exceeded during regular operation, since doing so would increase the risk of thermal damage to the connector. When a threshold is exceeded, a visual warning appears on the display and an audible alarm is triggered. Optionally, automatic system shutdown can be initiated via the included splitter cable. The preset threshold values can be adjusted through the configuration menu.

Cooling
Due to unavoidable contact resistances at plug connections which result in power loss, additional heat is generated during the operation of high-performance GPUs. To ensure controlled heat dissipation, a semi-passive fan has been integrated, which operates silently at idle and activates automatically with increasing power draw and temperature. The CNC-machined aluminum housing features ventilation openings and serves as an active heatsink. Optimized openings in the rear PCB guide airflow around all heat-relevant components including the graphics card power connector.

User-Friendliness
The WireView Pro II is available in two connector orientations, making it compatible with almost any graphics card with a 12V 2x6 connector. The downward-facing connector orientation enables clean cable management, and the device simultaneously acts as a 90° adapter. The integrated TFT-IPS display offers multiple views that can be configured directly on the device. The device is fully functional as a hardware solution and is additionally complemented by software (WireView2-SW-1.0.3), which is available in the product’s download section.

Automatic Data Logging
An integrated memory logs relevant operating data at regular intervals to enable traceability of potential error events. Logged values include per pin current measurements, total power consumption and the PCB temperature near the 12V-2x6 output connector (T-Out). A data record is stored every 60 seconds. The memory supports approximately 340 days of continuous usage or around 3-4 years of typical operation before the older entries are automatically overwritten. The collected data supports both failure analysis and the continued development of safer plug connections within the community.
