Edit: title should be "Check your rail splittings"
Think I found the issue. I bought this cable:
Now on my new Straight Power, one PCIE connector uses both rails (manual also clearly states which PCIE slot you should use, this was not mentioned anywhere in the Pure Power manual) but on the old PSU it seems to not be the case. There I should have used both PCIE slots ...
So it looks like the GPU was only using one rail the whole time.
Pretty easy to miss tbh. Either be quiet! should have specified that this cable does not work correctly with the Pure Power or make a bigger disclaimer in the manual on how to properly connect the GPU.

Now AMD just needs to look into better supporting an USB-C KVM 😡
When I checked, the Pure Power had weird power tables, with the 12V rails being shared, one for GPU + CPU and another for GPU + Motherboard + Drives (on the Straight power the GPU has a dedicated 12V rail I think.)
The USB-C would also require some extra wattage to power the devices connected I guess. I don't think that would be enough to cause issues, but electronics are weird (like USB3 external hard drives affecting USB2 wireless devices.)ID: gw6r5fn
Updated my post. You seem to be right.
PCIE slot on the Pure Power is only connected to one rail. So I should have used both.
This was not really mentioned anywhere expect if you check the tables manually. Also used a be quiet! power cable which had no disclaimer that it might not work with Pure Power correctlyID: gw5ifgw
USB-C theoretically did not need to power anything because I used a powered USB hub :dID: gw6idym
No but the USB controller on the board required power to operate. If your PSU is drooping under load it could easily explain the issues.
that's weird, be quiet! is reputable brand though
so all new high performance graphic card minimum requires 850W psu to run well?ID: gw617xb
I think for most users 750 is enough, but it does depend on how PSUs handle those huge peak loads (I have a 750w gold CoolerMaster pay, 3080 and a 5800x and my systems rock solid after the USB fixes)
I guess at this point going for an 850 is probably your safest bet especially with some of the pre-overclocked cards? Love to see a like 4 popular 750w PSUs vs modern high end GPUs to see how they handle it! Be some good informationID: gw63j4r
Yeah, i even ran R7 3700X and RTX 3080 with be quiet! 600W bronze with minimum setup and having no problem whatsoever for few months playing MSFS intensely But now I change to CoolerMaster 850W gold so I could add few hdds and coolers, and for safety measureID: gw6dtpl
Brands mean nothing when it comes to PSU's. Literally all of them have some cheap crap PSU's that you really shouldn't buy.ID: gw807fd
I have had a 6800XT running with a 3600 on a 550W PSU with no problems for 6 months.
Also had stability issues with certain PSUs in a dual PSU config with v64. Fixing them is always a reminder to not cheap out on a PSU and always overspec, due to peak/burst power draw of multiple modern GPU models from both manufacturers.ID: gw5wp1l
I'm happy that I still have my Cooler Master V1000 Gold-rated unit from the days I had a dual R9-290X setup (600W+ draw from the GPUs alone...). That 1000W PSU then carried through to my Vega 64 and 6800XT with zero power issues. If anything, it's had it easy for a while now.ID: gw7uw21
I have a Be Quiet Straight Power 1000W Gold with a really nasty setup in terms of power draw, no issues so far.
BeQuiet is a pretty quality PSU manufacturer in my experience, not sure if it's the right idea to mislead people into saying that it's a cheap power supply. People had all kinds of problems as soon as the first gen of Navi came out, some where the power brick extension itself was a fault and not the hardware itself but many were also due to PSUs having separate power rails and people wiring the VGA power cable to the same rail which caused all sorts of trouble.
Regardless, it fixed your problem so that's good to hear.
I doubt the PSU was the issue, but it's always possible there was some power line noise too strong for the filtering on the video card to handle.... But then I would expect stability problems before USB problems.
I had issue with a Seasonic Focus Plus 750W with 6800xt, under load (overclocked) it shutdown a PC.
Now running on be quiet! Straight Power 11 Platinum 850W and all is fine!ID: gw76kkw
I had a Thermaltake Smart 600w I got for my build in 2017
Upgraded from an RX580 to a 3060 ti
Poor little guy got kicked to the curb and I grabbed a Corsair 850 RMx
Overkill, but better over than underID: gw77iqq
Interesting that one of the best PSUs can't handle it, but an 850W handled it just fine. Makes me wonder if they lowballed the PSU requirement, and it should've been 850W. Though I guess the average user doesn't overclock.
Just goes to show though that PSUs are starting to get behind the requirements of future GPUs in general. The 3090 comes to mind with the triple pcie-8pin requirement on some products.
Hopefully the next generation of GPUs shows a reduction in wattage, otherwise we're going to see another slugfest of cards running at 80C+ normally and end up back in the Radeon Rx 2xx days (no offense, but those cards were awful imo. Even the 295x2, as beautiful as it is, was horrendous).
be quiet! cheap PSU? I literally used REALLY cheap PSU in all my PC-s (random 450W on, njoy 500-550W for RX580, now Thermaltake Smart RGB 600W, never had a problem. It's not the cheap brand that's bad, it's the specifications. Also, even now, I kinda had "GPU problems" (restart at high load) when using one power outlet from the house, so it depends on alot of factors.ID: gw6iqpw
What's the betting that power outlet has a poor / high resistance on the earth (ground)ID: gw6tin2
Yea, I already changed that one, it was one of the olders from the house, actually I guess the original one back from the 90's.
Thats why I buy only Seasonic Prime. I had a Bequiet 1000 W a few years ago, it failed completely, after infinite RMA times they sent me a 1200 W with heavy coil whine. I rather buy a Seasonic 650 W which has zero noise or coil whine. The 12 year warranty alone tells this is something I won't upgrade in a while.
BTW, even the 500 W Corsair CX PSU I bought for 30 € when I had to RMA that bequiet turned out to be better, it served in my secondary PC until last year. Now it has issues under load, but it still lasted way longer than that Dark Power Pro and I bought it used.
Don't trust brands when it comes to PSUs. Read a review of the particular model you're interested in from someone who knows what they're talking about and actually owns an oscilloscope. And make sure you're buying the same model, not some "updated" model with the same name.
Unless something has changed recently, I don't think beQuiet is a "cheap" PSU brand. Sure, there will always be edge cases and faulty units from even the most reputable brands but making a generalization just on a single personal experience seems off. Surely it's possible that 700w was simply not providing enough juice to all the components.ID: gw6ply5
Think I found the issue. I bought this cable:
Now on my new PSU one PCIE connector uses both rails but on the old PSU it seems to not be the case.
So it looks like the GPU was only using one rail the whole time.
Pretty easy to miss tbh. Either be quiet! should have specified that this cable is supposed to only work correctly with the straight power or make a bigger disclaimer in the manual of the Pure Power on how to properly connect a GPU.
Was the fan bad throughout this period? Perhaps the PSU had problems supplying stable current because of the bad fan.ID: gw5ldfh
No it just recently started making noise. It worked fine but the noise was not something I was willing to endureID: gw7685y
Is your fan pulling from below the case or from inside?
I wonder if something got sucked in that damaged the fan and PSU
6800 and 6900xt can trigger overvoltage pzrotexrion when over clocked from micro spikes . 70 amps on 12v rail was enough for mine
My PSU makes a really scary noise when booting up my PC. It's perfectly fine otherwise; waking the computer from sleep, gaming, etc. is all normal. But first booting up the PC after it's been turned off completely, there's a rapid-clicking fan noise like the fan blades are slapping against something really hard.
I've already gotten a replacement once, and it's been months since then so I doubt I can do it again, but it is nerve-wracking. It's a Thermaltake Toughpower GF1 850W 80+ Gold, though, and I believe Thermaltake is a reputable brand? I just don't know.ID: gw7rmvv
i have the 650 toughpower GF1, dont have that issue. running a 5600x/5700xt.
I agree OP. I purchased a low quality G2 Supernova and Seasonic unit for my 6900XT. Both were gold rated, but both buzzed super loud under load. I initially ignored good advice and didn't get an RMx series that were known to be quiet because availability was better on the other two. Anyway, I'm not on RMx 850 and loving it. So freakin quiet.
I went overboard many years ago with a 1500w PSU (The Radeon 2900XT in Crossfire would shut down my 750W at the time), still works fine and without any stability problems.
Got it super cheap, also.
After two be quiet! PSU failed on me I switched to Seasonic. Their premium models have 12 years of warranty. A company must be really fucking confident their products are good to give that much. Never had a single issue since.
did you daisy-chain your PCI-E power cables?ID: gw6k94m
Updated my post, seems to be a mismatch between cable and PSU.
Pretty easy to miss tbh. Cannot test now but I guess if I connected to two PCIE slots on the Pure Power it should have worked aswell.
Also had no reboots or crashes which would indicate that the GPU is not getting enough juice. Only USB was dropping out...
