Concern About Shunt Resistors on ASUS GeForce RTX 5090 32GB TUF Gaming

[jjohanssonn]

Hello,

I recently purchased an ASUS GeForce RTX 5090 32GB TUF Gaming, but I haven’t received it yet. However, over the past few days, I’ve seen reports online about connectors and power sockets melting on FE cards.

I also found out that the RTX 5090 Astral will likely handle this issue better due to having six shunt resistors, compared to only one on the FE cards. This information is easy to verify for the Astral model, but I haven’t been able to find anything regarding the ASUS GeForce RTX 5090 32GB TUF Gaming.

The only confirmed detail I found is that the TUF model does not support Power Detector+, which gives me some concerns. I don’t want to risk melting my $2,700 GPU due to this issue.

Can you provide any official information on how many shunt resistors the ASUS TUF 5090 has?

What safety measures does my TUF card have to prevent this issue compared to the FE models? Or is it at the same risk level?

If the risk is just as high as on the FE model, I might have to reconsider my purchase and return the card in favor of the Astral model, even though it costs an additional $650 here in Europe.

Looking forward to your response. Thanks in advance!

hi
As far as I know, the shunt resistor should be two groups,
Since many review websites don't have TUF 5090 PCB pictures, we can't give a very definite answer, but many AIB designs basically have at least 2 sets.

The FE version only has one set, probably because it wants to save PCB space....

Hi @jjohanssonn ,

Thank you for your inquiry. We understand your concerns regarding the potential melting issues with the ASUS TUF Gaming 5090 graphics card.

Please rest assured that the ASUS TUF Gaming 5090 has a sufficient number of shunt resistors. Our products, including connectors and cables, comply with industry standards, and each graphics card undergoes rigorous burn-in testing during production to ensure there are no safety issues under normal use.

Here are a few situations that could potentially cause cable melting, and we recommend you pay close attention to them during use:

• Connector was not fully plugged
• Bad quality 3rd party cables/adapters
• Excessive bending of the cable

Additionally, Power Detector+ is a preventive function, and its presence or absence does not have any impact on product failures.

If you encounter any abnormalities or issues during use, please feel free to contact us. We will be happy to provide you with assistance.

Thank you for your support and understanding.
