ASRock has unveiled a new line of power supply units (PSUs) aimed at improving safety for users of NVIDIA’s RTX 50-series graphics cards. These PSUs feature built-in thermal sensors that monitor cable temperatures and cut power if overheating is detected — helping to prevent damage and reduce fire risk.
Why It Matters
The move comes in response to ongoing concerns about overheating connectors, an issue first seen with the RTX 4090 and still affecting some RTX 50-series cards. At the root of the problem is the 12VHPWR connector, where uneven current distribution across the cable’s wires can lead to excessive heat. In worst-case scenarios, this has caused connectors to melt.
Key Safety Features
ASRock’s solution is simple but smart. Their new PSUs include:
- Two 12V-2×6 connectors – These are standard for high-end GPUs.
- Additional two-pin thermal sensors – Embedded in the connectors, they monitor the temperature at the cable interface.
- Automatic power shutoff – If the sensors detect that temperatures are too high, the PSU cuts power to prevent further damage.
This proactive approach adds a layer of protection that could help avoid the physical damage and potential hazards associated with overheating cables.
Part of Taichi and Phantom Gaming Line-ups
The new PSUs will be available under ASRock’s Taichi and Phantom Gaming brands, both known for their focus on performance and reliability. While full specs, pricing, and release dates haven’t been confirmed yet, the addition of thermal safety features will likely appeal to high-end PC builders and gamers using next-gen GPUs.
A Step Towards Safer High-Power Builds
As GPU power demands continue to rise, especially with the latest RTX 50-series cards, safety features like these could become essential. ASRock’s thermal-sensing PSUs offer a practical response to a well-documented issue — one that could help users avoid costly damage or system failures.
