RTX 5090 Owner Built An Open-Source Tool That Shuts Down PC If It Detects The 12VHPWR Cable Drawing Too Much Power, But It Can Only Work On Specific GPUs
A user has developed an open-source tool to automatically shut down PCs if it detects dangerous power levels in the 12VHPWR cable of specific ASUS RTX 5080 and 5090 graphics cards. The tool aims to prevent hardware damage caused by excessive power draw, a known issue with these high-performance components.
Why it matters
This highlights the intersection of hardware reliability issues and community-driven software solutions in the high-end gaming PC market.
It’s well-documented that when an RTX 5090 is running at full tilt, it can end up melting the 12VHPWR connector due to its wattage-guzzling attributes. As powerful as it might be to deliver record-high framerates, this is one major trade-off that gamers have to watch out for. Fearing that the same fate will befall his GPU, one user has developed an open-source tool that automatically shuts down the PC if it detects that the graphics card is drawing too much juice.
Whether or not other RTX 5090 owners find the tool from Redditor “CoolerThanNos” helpful or if they prefer undervolting the GPU using software like MSI Afterburner, the open-source program available on GitHub to download is currently compatible with ASUS’ Astral lineup of RTX 5080 and RTX 5090. The reason these two graphics cards are mentioned is that ASUS has placed individual current sensors per pin to monitor power draw.
