The Thermal Grizzly WireView Pro GPU 1x12VHPWR (TG-WV-P-H1N, EAN 4260711991073) is a power and temperature meter for GPUs with 12VHPWR connector, which is placed between the power supply and the graphics card and displays power (W), voltage, amps and temperature on an OLED screen,with built-in connector detection and audible alarms.
What it measures and displays
-
Measures real-time power, voltage and current flowing through the 12VHPWR connector, showing instantaneous, maximum, minimum and average values for the last 60 seconds on the OLED display.
-
Includes internal temperature sensors in the connector area and allows two external probes to be connected to monitor, for example, memories or GPU VRMs; all data is displayed on the screen.
Security and alarms
-
It has a pin detector (pin detection sensor) that verifies if the 12VHPWR cable is correctly inserted and what type of cable it is (150/300/450/600 W); if it detects bad insertion or values out of range, it activates an acoustic alarm.
-
Temperature and current thresholds can be set, so it warns if the connector or cable gets too hot, helping to prevent problems such as 12VHPWR meltdowns typical of high-power GPUs.
Connectors and compatibility
-
This version is the "Normal" (N) 1×12VHPWR version: it connects in-line between the 16-pin connector on the GPU and the 12VHPWR cable from the power supply, maintaining the standard layout (clip out PCB).
-
It is intended for modern GPUs with a 12VHPWR connector, such as the NVIDIA RTX 40-series and future cards using this standard; it only measures the power coming through the 12VHPWR (not the power coming through the PCIe slot).
