Hi guys. I think my 3090 is dead. I was having a gaming session last night when all of a sudden my pc shut down and wouldn’t power on again. The only way I could get my pc to boot was to remove the power cables from the gpu. As soon as I reconnect them it doesn’t power on again. Motherboard standby lights are lit up though. My gpu is on a riser cable but even with that detached it still won’t power hence the reason I think it’s the gpu. What do you guys think? It’s in a water loop so I’m probably not gonna be able to rma.
 
Put the stock cooler and pads if you have them back on, test it and if it still knackered RMA it anyway.

Which model and brand is the 3090 ?

Are you sure it's not a PSU issue too ?

What are the full specs of your system ?
 
Sounds like short on power rails.

Your psu detects short and cuts off to prevent more damage and potential fire.

Put card into it's original state and rma.
Do not fak about Any more. All u gona do is risk burning a hole in pcb.

If to make sure, take a multimeter and probe 8 pin connectors, u will see zero resistance there. It might be easy to fix , but if I had to guess I would put my money on a mosfets to the gpu.

Thanks for your help guys. My specs are 5950x, asus strix oc 3090, 32gb gskill ram, asus hero viii motherboard. My powersupply is a phanteks revolt x 1200w. The gpu is fitted with a ek block and in the same loop as cpu. 2x420mm rads and 1x 280mm rad. I think I’ll just drain down and try to fit the original cooler. See if I can see any damage and try to rma. I was actually playing destiny 2 when it shut down. No wonder :p

Are any leds lighting up at the PCIE power connectors on the ASUS STRIX 3090 ? When you start the system up look at the back of the card under each PCIE power connector if an LED is lighting up under any of them.

Like on this video the lights blinking or they maybe just on and solid red. If they are on it could mean a power supply issue, you will need to check the manual if they are on and what they are doing and the order the light up with and if flashing or solid on.

Watch this video from the 3 minute point he talks about the leds and power connectors on them.



Showing where the leds are.

If u cant smell burns then u won't see visual damage.

Give hi fi to your psu. Its over current Protection Worked.

Or the psu has some dead rails on it now ?.. pure guessing and made up rubbish. Doesn't mean the protection worked at all, it could just have taken out some rails on the psu and now no power to the gpu or the rails are damaged and once a load is put on them the psu doesn't allow the pc to start up as it is basically in fault found mode.

Come on guys quit the silly guessing if you don't know don't reply to help people that need help.. All you are doing is adding to the frustration of the person needing help even if they don't realise your help was wrong.


Like this comical event yesterday...

That is not a missing piece, it's a slot for if you want to mount a liquid cooling pump to the back of it, specifically it's an Intel style mount. Packaging looks sealed. Might be worth talking to OCUK if you're really worried about the packaging, but that's definitely not a missing piece. I imagine OC will ask you to try out the GPU to see if it works.

GPUS now have a space in the back for intel water coolers...:rolleyes::cry:.. Seriously this is the level of help on here recently.

This.
Btw u are right, maybe it is psu that is shorting, but considering the description and % of gpu failure vs psu failure, I would bet my money on gpu .

Also if gpu is shorting and u keep powering on and on, then u simply asking for a magic smoke and 12v into gpu chip.

Actually I think they were on. I could see a solid red light. I thought it was a reflection from my motherboard. Will check again when I get home. I didn’t realise they had leds there.
 
So I retried my pc when I got home. The leds do not light up when connected to 12v rail on the power supply but do illuminate when disconnected from it. Pc still will only boot when gpu is disconnected from the 12v rails. So the question is gpu or power supply. How can I test without another gpu or power supply?

If you're getting video when removing the 3x8pin power connectors I would try a different psu first. Not sure where you purchased the psu and gpu from but if from okuk maybe send both back for them to test which is causing the problem if you don't have another psu or gpu to test with or another computer you can test the gpu on.

No I’m not getting video my cpu hasn’t got intergrated graphics. It just tries to post and keeps looping until it comes up with an error code.
