Key takeaways
- Thermal Grizzly announced their WireView Pro 2 device, which monitors the temperature and current of the 12VHPWR connector. This improved version will also offer data logging for three months and should cost $100.
- WireView Pro 2 is expected to be released by the end the year, with improved hardware and software compatibility.
The WireView GPU Pro is a device from Thermal Grizzly that measures the power consumption of a graphics card.
The device connects to the 12VHPWR power connector of the graphics card and is hooked up to the power supply through a power cable. You can then see the power consumption data on an OLED screen.
It also features a connection detector and temperature sensors, as well as a buzzer for audio warnings for overheating. The device measures power consumption every 60 seconds and can be used to monitor consumption over a given period of time.
Interestingly, Thermal Grizzly is already planning the WireView Pro II, which will be an updated version of its predecessor. Instead of the 60-second window, it will record metrics (current, voltage, and temperature) every 5 seconds and store data for up to 3 months.
The WireView Pro uses per-pin sensing to monitor each of the 16 pins of the 12VHPWR connector. This way, it can identify which pin carries too much current, which one is loose or oxidized, and will also detect anomalies quickly.
The aim here is to identify issues before they cause any permanent damage. However, Roman from Thermal Grizzly ( ) also acknowledged that it might not always be true, as overheating can occur due to subtle resistance on a contact point.
Also, he said that WireView wasn’t completely fail-proof. Twelve of the 3,700 units that used a 12VHPWR plug had issues. This equates to a failure of 0.3%. Thermal Grizzly, despite the low failure rate, is ‘learning from mistakes’ to create a better product.
There’s also a small two-pin connector near the WireView USB-C port and a Y-splitter cable, which can connect it to the motherboard’s power button. That way, it can trigger a system shutdown if needed.
The USB-C port can also be used to hook the WireView up with your PC and configure settings via compatible software. You can store data, including potentially images or other files, and then uninstall the software. The device will work independently.
All Thanks to Nvidia?
Roman sarcastically thanked Nvidia for its poor 12VHPWR connector, which led to the conceptualization of a product like WireView. Nvidia’s 12VHPWR is often used in high-end GPUs like the RTX 4090 and has been reported to melt or overheat.
Some people have even lost entire GPUsbecause of this. WireView is a simple product that has helped people monitor temperatures and save thousands.
As they say, one man’s loss can be another man’s gain. Thermal Grizzly has proved this to be true. NVIDIA’s connector mistake would have prevented the creation of a new product. Nvidia may have upgraded its 12VHPWR to a better version over the years, but reputational damage has already been done.
WireView Pro 2 will be available by the end this year for a price of about $100.
The custom 12VHPWR plug would take at least three months to produce, and therefore cost around $25 more. Plus, with improved hardware, software compatibility and per-pin current sensors, the $100 price seems reasonable.
Nvidia could throw a curveball by moving away from 12VHPWR and to a new connector, rendering products like WireView Pro uncompatible with different GPU versions. This is easier said than accomplished, given the cost and operational challenges.
