Thermal Grizzly WireView Pro GPU 1x12VHPWR Normal

Device for measuring and monitoring graphics card power consumption via the 12VHPWR connector with OLED readout, connector detection, temperature sensors and an audible alarm.

The WireView Pro GPU connects between the graphics card and the power supply to display and record volts, amps and watts on an OLED screen while detecting cable specification and issuing warnings for incorrect connections, overcurrent or overheating.

• Displays current power (W), voltage (V), current (A), min/max, 60‑second average (RAVG) and total energy (Wh)


• Measures and records power only through the 12VHPWR power connector (does not measure via the motherboard PCIe slot)


• Connector detection for 150W / 300W / 450W / 600W cable specs; available in Normal and Reverse pin orientations


• Internal temperature sensors at the power connectors plus two external 10K NTC sensors with 5 cm and 20 cm cables


• Audible buzzer alerts for incorrect cables/connections, exceeded temperature limits or adjustable current limits


• Aluminum housing with optimized cable management and an OLED for quick, review‑friendly measurements

Useful for assessing GPU power use and detecting power peaks on high‑power cards; the device can become very hot during operation, so avoid touching the casing and allow it to cool after shutdown.
