ASRock Taichi RX 6800 XT Black Screen and No Signal Error [GPU or PSU Problem?]

[Chronosis]

Hello people, since one months ago, I've been having a problem and I don't know whether it's a gpu or psu problem. I randomly encounter black screen and no signal error regardless of playing games or surfing through the internet and etc. The pc still runs when I'm having the issue, I can hear my friends on discord or videos from youtube and etc.

Whenever I restart the pc after I encounter this problem, the VGA led on the motherboard lights red and therefore, I won't be able to boot the pc. To overcome this issue, I basically unplug and re-plug one of the pci-e power connectors that goes to the graphics card.

Whenever I reboot the pc after doing this unplugging and re-plugging pci-e cable solution, I see that in the device manager my graphics card is shown as "disabled". I try enabling the graphics card but I get a driver error from amd software. Despite getting this driver error, I restart the pc and this time pc runs fine until I encounter the same problem of getting black screen and no signal again. I have to do all the work again to be able to use the pc again :/

I have Cooler Master MWE 700W Bronze V2 230V as a power supply unit. From some forums I saw that people advise not to plug the pig-tailed (I hope that's the correct term for it :d) pci-e power cable to the graphics card but I don't have any other option rather than plugging both the normal and pig-tailed cable because the psu I'm currently using have 2 pci-e cables that have additional pig-tailed pci-e 8 pin cable for each of them, making a total of 4 pci-e 8 pin cables.

To make it more clear, I added an image.

Things I tried:
Updating gpu driver,
Updating the bios to the latest version,
Disabling zero rpm function on amd software
Undervolting through amd software
Increasing the power limit through amd software
Switching to win10 from win11
Switching pci-e gen switch from auto to gen3

What would be my problem? I think it's a psu related issue but I don't want to spend money on a psu without being "almost" certain about that the psu is causing the problem :d
I'm thinking about buying a 750w gold certified psu. I would have wanted to buy a more powerful psu with higher wattage but in Turkey the prices are very high, unfortunately.

My Specs:
Motherboard: MSI B350M Mortar (Latest BIOS)
RAM: GSkill FlareX 2x8 DDR4 16GB
CPU: Ryzen 5 5600
GPU: AMD ASRock Taichi RX 6800 XT
PSU: Cooler Master MWE 700W Bronze v2 230v

It does not sound like a PSU problem, since your computer is still running and you can hear your on-line friends.

Also, it does not appear to be a problem with your cabling because, assuming I read you correctly, it worked fine until a month ago.

But the best way to be sure is to swap in a known good spare PSU. This is a good idea regardless, since EVERYTHING inside the case depends on good, clean stable power - including the graphics. And while in there, make sure the interior is clean of heat trapping dust.

Beyond that, you need to try a different graphics card and see what happens.

I have the brother of this card, Phantom Gaming with the same issue. After much diagnosing, turned out it was the card as one of the DisplayPort was starting to fail. I ended up rma the gpu and it has been working fine since. I suggest rma the card if you have already tried a different DisplayPort. Asrock sent me a new card.

I bought it from Amazon Japan and the guarantee is not available unfortunately :/
I'll try using the other displayport

I forgot to say that I'm already using the hdmi port of the graphics card. However, I'll try buying a dp cable and using the dp port on the graphics card.

I'd believe you should plug both cables (with 8-pins) into the card and not just one, either the PSU has some over current protections on each its 8-pin cable or the power isn't stable enough; besides BIG Navi 3x cards are know for quite large power spikes that, if aforementioned my 2 points do not cover, your PSU just doesn't handle and you'd have to upgrade it to the latest LLC resonant design.

Edit: Did a little digging, looks like your PSU is LLC design, so try and connect both 8-pin cables to the card and report. If it still looses output, it's powerspikes are just too much for this 700W unit.
I just checked, at AsRock they recommend an 800W PSU for this card, so...

If all else fails, you could try to contact ASRock. If I remember correctly, it replied to me in a day, and definitely requested a copy of the invoice. I sent the GPU to Southern California. If you have a copy of the invoice from Amazon Japan, that might fulfill the requirement.

As for the PCI-e plugs, if I am reading it correctly, you have 4x of PCI-e 8pins, with 2 of the pigtails hanging and not being used, correct? That should be fine. However, come to think of it, the PSU might be the issue afterall, as it may not be able to handle the transient spike requirement of the card.

I'm almost sure it's a psu problem. I'm saying this because I just tried unscrewing the windowed panel of my case and while doing this the windowed panel moved the pcie connectors a little and I suddenly got the black screen and no signal error again. It looks like I need to buy a new psu :d

I think I caused a misunderstanding, I'm not a native speaker so I believe I made mistakes while writing the issue I'm having :d I have 4x pci-e 8 pins including the pig tailed ones, so I need to use at least one pig tailed cable to install the graphics card

Get a 1000w PSU. Prices have dropped a lot recently so it might not be too expensive to try that option first before RMA.

Unfortunately my budget won't be enough for a 1000w psu but I'll try to buy a 850w psu with %80+ gold certification. RM850 will probably be the one I will be buying

Except that could mean the PCIe connector on the motherboard is the problem. You need to first, ensure all the connectors (data and power) are securely fastened.

I just tried unscrewing the windowed panel again. Soon as one of the pci-e 8pin gpu cable moved a little, I encountered the same problem again. I don't want to try the method again because I worry that I might damage the gpu :/

 

[Bill_Bright]

I'm afraid I am not getting through here.

There are two parts to every connection. Just because problems happen when you wiggle a cable, that doesn't prove it is the cable that is bad. Let's hope it is, because replacing a PSU typically is much easier, and more affordable than replacing a motherboard.

Just recently checked all the connectors and it seems all of them are securely fastened.

I hope it's a psu related issue

Perhaps you didn't read my edit of my post above, ASRock on their webpage recommends 800W power supply for this kind of card, so yours is definitely not enough to handle its power draw.

 

[Toothless]

I'm running an XFX 6800XT on a 850w. Overclocked hard the card maxes at 330w pull. Unless your PSU is junk, it's the card.

The pci-e cable that goes to gpu moved a little when I was opening the windowed panel of the case, leading to the issue. So, I believe it's about either the pci-e connector cable or the psu itself. I'm thinking about buying extender cables for the pci-e power pin cables but it may be risky in terms of power delivery and voltages, I believe.

While it is true that ASRock does indeed recommend a 800W supply, recommendations by the graphics card makers are ALWAYS way overkill (at least for the vast majority of users). This is because the last thing those makers want to do is recommend an underpowered supply. Therefore, they assume the user is using a power hog for a CPU, lots of power hogging drives and fans, and much more.

This is why, to properly determine power needs, one must research ALL the components that will go in that machine, then calculate the total amount of power needed. But that is a real PITA - even for experienced professionals. So I recommend using a good PSU calculator and the best and only one I use and recommend is the eXtreme OuterVision PSU Calculator.

As seen here, that computer could easily get by with a nice 600W supply. And note I even padded the results by bumping up the CPU utilization to 100%, added 2 SSDs, 1 hard drive, and even a Blu-ray drive, plus 3 140mm fans and said the computer will be used 16 hours per day.

Therefore, the OP's 700W supply is not only more than adequate, but even has enough extra headroom to upgrade to, or add even more power hungry devices ASSUMING that PSU is working properly.

So possible defective power connector on the card. Stop touching it.

If you could get a higher wattage power supply to test it, would be ideal, otherwise I just don't know.

It's definitely not capacity of the power supply that is the issue.

Pavie - do note the computer was working fine with that 700W power supply until a month ago. This may be a PSU problem but as Toothless notes,

It's definitely not capacity of the power supply that is the issue.

Thats easy to obtain
