Is it normal for an Asus RTX 4070 Ti Proart to have red LED on while the computer's running?

As the title said. I recently upgraded from an old college laptop to a new PC and I'm not sure if a graphics card is supposed to have the red LED on all the time? I'm sorry if this has been asked before but I'm really new to these RTX cards.

Try looking through these posts on the Asus forums. It seems to be related to the new 16-pin connectors.

Sometimes with my old 3080 I also had the red VGA light on yet everything worked, go figure...

Solved it usually by reseating the card, bad contact somewhere

Thanks for the links. I read up and nobody was really sure what the problem was. Very confusing indeed.

 

Maybe I'll try and reconnect the pin connectors, see if it fixes that.

 

Thanks again!

from what I was reading it seems if you are using the 2, 3, or 4 8-pin to 16-pin adapters the red light is likely to always be on. If using an actual 16-pin connector directly from the PSU the light should only be on when the system is powered down. It's only speculation as I've yet to own a card that has the 16-pin connector and with all the problems people are having I'm quite happy about that.

Now that you mention it, yes. I've recently noticed that the red LED is always on even on PC shutdown and it's connected with an adapter. I guess a way for ASUS say that the power is fine?!

The 16-pin has a communication pin for the GPU to tell the PSU that it needs power and that it's going to take it so the PSU can provide said power without damaging itself or the card. That pin can't talk to the PSU with an adapter. So I imagine that light just means the GPU isn't communicating with the PSU so it will always be on with an adapter and only on when the system is shutdown with a genuine 16-pin from the PSU.

That's probably it yes. I'm just glad that the GPU is not exploding really :3
