ASUS ROG Strix RTX 3090 OC - Blinking Red LED

[Beauzinga]

Hi all,

Recently I have noticed that a single red LED is flashing on one of the three power connecters, the far left one. I need to turn off my PSU at the switch to make it stop blinking.

Attachment 94563

This issue has only started recently and only appears when playing games.

My PSU is a Corsair RM850x, I use three separate PCIe power cables as recommended by ASUS, the card is running at stock with the latest bios.

You can see my full computer specifications in my profile.

Appreciate any help.

Shutdown your PC, remove the main power cord from your PC power supply for couple of minutes (5 mins). Insert back the power cord and start your PC. This may help.

It may also PSU over load or cap not provide sufficient capacity load. It also depend how your internal peripheral drawing power from PSU, and not much juice left from PSU. 850W PSU my not sufficient power to drive 3090 let alone OC variant. But some of them claim it sufficient enough and debate goes on. It all depend the part and peripheral within your system power drawing from your PSU.

Thank for the reply.

This is what I currently do but still comes back.

What I find interesting is that I've never had this problem even when I've been using Asus AI overclocking for the cpu in the bios for well over a year now. It just all of a sudden started in the past few days. I have a feeling it could be a faulty trigger or a random high voltage peek.

For now I have disabled the AI overclocking and just see how it goes with the power now.

Beauzinga, I've had the same issue on my 3090 OC - from day 1. And I have a 1000W PSU.

My firm believe is that this power overload detection is WAAAAY too sensitive and poorly constructed. So I have chosen to completely ignore it.

In the "GPU Tweak III" app, there is a nice Power Detect switch. Mine is permanently in OFF position and my 3090 still runs perfect, even when overclocked.

Cheers.

Hey,

Thanks for the reply.

From what I've gathered online, it seem that other people are also having this issue from 850w to 1200w power supplies. They do also mention to turn off the Power Detect in GPU Tweak III. Some people think its a bug too that ASUS need to address but do you know if disabling it via GPU Tweak III it will say off if I uninstall the software. Also is there any risks that come by disabling it? My computer seems to run perfectly fine and has been since day one.

I personally do not think removing an add on software will cause any negative effect. I do not install any GPU Tweak III on my system so I cannot comment any about it. But those online wrote that it having issue with PSU which I do not think it a fair statement. I tried 1000W, 1200W even 1600W PSU with no issue. Once a while I did encounter blinking red light but what I did was to switch off the PSU and remove the main plug for a while, reconnect and it disappear. What my guess was the while the system turn off the power distribution may not discharge the GPU power completely. Please correct me if I am wrong.
