GPU - teal blank screen, no signal to monitor (AMD Sapphire R9 280X X Vapor)

[robert_8]

Hello,
Problem occurred 12 hours ago during playing, when I got a Teal screen, had to restart, loaded game back up, same thing. (desktop was working fine)
After 3rd restart, black screen, monitor wouldn’t get signal from GPU, couldn’t get into Uefi.

Situation right now: - GPU cleaned (was dusty)
- now i’m working off of the Intel onboard graphics only
- GPu seems to get power, fans work ok, led also, when powered with with 2x 6+2 pin PCIe
- tried all the display slots from GPU to connect with, but monitor says “no signal”, if i unplug it says "cable unplugged ofc
- reinstalled desktop software for AMD gpu
- didn’t give gpu to friend for testing (yet)
PSU is called Sirtec High power Element smart 750w (not sure if i’m allowed links)

The GPu seems to have power but incapable of displaying anything. Let me know if i need to take it to the hardware repair.

Hello

It sounds like your graphic card has failed. I will get some more opinions in here.

Welcome to PCHF robert 8,

PSU is called Sirtec High power Element smart 750w (not sure if i’m allowed links)

There is one thing that is possibly worse than using a known poor quality brand of PSU and that is using one that is unheard of, for brands of PSU to trust and brands to avoid please refer to the links in my sig.

Your, GPU AMD Sapphire R9 280X X Vapor, this card requires a 750W PSU with a minimum of 42 amps on the +12V and 1x 6-pin + 1x 8-pin.

The PSU that you have been using, Sirtec High power Element smart 750w, specs here by the manufacturers own admission can only produce 675W so has been depriving your GPU and other hardware of the clean and stable power that it needs, this may or may not have permanently damaged your GPU and one or more of your other components.

Without swapping in a known good brand and adequate spec of PSU you have no way of knowing this, best suggestion would be to get your Sapphire R9 280X X Vapor video card tested by a local tech or tech store that has the required hardware to test the card, this unless you have a family member or friend with a computer that has the appropriate spec PSU fitted and who would be willing to test the card for you.

Hi Robert.

I do agree with Phil. I would look at replacing that power supply as soon as possible since continual use of poor quality power supply units from brands that we haven’t heard of can damage your hardware components over time especially if they are incapable of providing their rated continuous power that they claim they support.

Since that video card requires a 750 watt power supply, I would look at getting this replacement PSU, Corsair CP-9020092-UK RM750x 750 W 80 Plus Gold Certified Modular 135 mm Thermally Controlled Fan Power Supply Unit - Black.

See if you can have your video card tested first to make sure that that card hasn’t actually died but it will require a system that can support the power requirements of the card.

If you have confirmed that the video card works in another system, then the culprit is your power supply but I would replace that power supply regardless because you don’t want that power supply unit to die and take out your other components with it.

[robert_8]

seems reasonable, thanks. Although me postponing to clean it from dust (it wasn’t even half bad dirty, compared to what I’ve witnessed during the years), and not being experienced enough to react to tell-tell signs like rare blue screens in the last period (assuming wrongly win10 causing them, since win10 HAD a lot of BS reputation), surely i’m to blame, rather than the PSU, which for 5 years i had no issues with at all. And yes i love corsair also, but Sirtec isn’t a no name Chinese brand exactly either) yes i see the horrible marketing name of the P.supply now, i have no idea why i got it. Oh yea, college budget and girlfriend.
Well see, what a reflow can do in a service, generally i’m lucky. I’m surprised none of you suggested it.

I would not suggest it, the card could be fine only to be placed in an oven and then rendered useless.

Sorry to say that most Chinese brand PSUs are only heard of because the end users have had them fail on them and they then have to post on tech forums looking for help.

Not long or interesting enough to warrant sitting down with the popcorn but take a look at the video here

Thank you, definitely inclined on buying a new GPU also, since reballing (70$) or reworking with second hand chip seems a temporary solution and costly at ~200$ total in the worst case.
The PSU will be replaced also. THX Evan for the suggestion. Just as an advice or hint, (since i don’t know the specs of the new graphics card yet) what should i be looking for in a new PSU, besides the 2x AUX connectors wattage requirements matching the power supply’s? Just get a 750watt from a known brand, check if the cabling fits my needs and that’s it? As a casual user it’s kinda hard for me to go into amps

Here is a review for some psu’s.. Best Power Supplies of 2025 - Top PSUs for Gaming PCs | Tom's Hardware

On the amps thing..the higher the amps on your 12 and 5 volt rails in a psu,means it can sustain the power needed without frying the psu,or in other words it is heavy duty to run your power requirements.

You need to make sure the unit is a modular which means that you can only plug in the power cable connections that you need and that its from a known brand like Seasonic or Corsair and that the unit is at least 80 plus bronze efficient because that will mean the unit is a higher quality piece of hardware.

Poor power supplies tend to be lower than 80 plus efficient in their continuous wattage rating and have lower amp capacity especially on the 12 volt rail.

For casual user’s having the appropriate wattage amount, a modular unit, and at least an 80 plus bronze efficient rating is a good starting point for choosing a power supply.

Are voltage stabilizers worth if i buy a 80 plus bronze =< rated? (since I have DAC, Amp, mixer, receiver, speakers, lamp also plugged in an extension cord with many outlets)
And what software for newbies do you suggest that will show me if all my PC components are well enough supplied? Literally show me verdicts “x is good” etc. not just show me numbers, cause i might or might not be able to interpret them correctly.

You would be better off with a UPS that also has AVR, some reading for you here

(since I have DAC, Amp, mixer, receiver, speakers, lamp also plugged in an extension cord with many outlets)

Care should be taken not to overload things, hope that the extension has a minimum of surge protection.

And what software for newbies do you suggest that will show me if all my PC components are well enough supplied? Literally show me verdicts “x is good” etc. not just show me numbers, cause i might or might not be able to interpret them correctly.

Most are only a guide** and should not always be taken as 100%, the two most accurate available tends to be the BIOS readings and any monitoring software they may have been provided with the MB, in this instance you should be using the AI Suite 3 program, see here

** Third party monitoring programs can give inaccurate readings if they conflict with a MBs own monitoring software which they quite often do.

If you also want a good estimation of how much power your computer is using you can use OuterVision’s Power Supply Calculator to see how much power your computer will use.

Any update for us Robert 8?

[robert_8]

Changed PSU and confirmed what i already knew on a friends PC regarding the Gpu, no display, fans + led work on it. Only option is to take it to a service, for a free diagnosis, even if i won’t rework it (if it’s the processor). I HOPE it’s a capacitor failure or something else .
I was playing with the idea of cleaning it more, applying new thermal pads, and paste on, but i doubt a miracle will happen. Taking it to a service is priority n1.

[phillpower2]

If the card was tested using the correct spec of hardware on your friends computer and it did not work it would suggest that the card is dead.

Taking it to a service is priority n1.

Best course of action (y)
