Issues with Abrupt PC power interruptions (overcurrent protection)?
Issues with Abrupt PC power interruptions (overcurrent protection)?
Hi,
first my system setup:
CPU: Ryzen 7 5900x
Board: Asus Crosshair viii Hero wifi / MSI Tomahawk
GPU: STRIX GTX3090 on a PCIe 4.0 Riser
PSU: 1200Watt BeQuiet Dark Pro 12
RAM: 32GB G.Skill Trident Z RGB für AMD DDR4-3200 DIMM CL14 Quad Kit
SSD: M.2 NVME Samsung Pro 250GB OS, +1TB Samsung Pro additional space
The entire thing is custom hardpiped and powered by EK-Quantum Kinetic TBE 300 D5 PWM D-RGB - Acetal,
thermals are not an issue according to hardware monitor
Display is on 1920x1080
Now to the issue:
My system keeps abruptly blackscreening under heavy load.
Event viewer code is 41 - 63 kernel power error,
which leads me to believe it is
most likely due to the PSU safety features kicking in.
I am not 100% sure yet if GPU or CPU load is the cause. Possibly both. The system has been running for
just about 3 years with rare black/blue screen restarts.
I assume i never really put it through its paces enough for it to reach the limit.
Now that system requirements for games have increased i might just have reached it.
The issue can easily be reproduced when i try to deploy in Tarkov or run Heaven Benchmark or
start the MSI afterburner oc scanner.
What i have done so far: Not kidding i literally put my RAM sticks into the fridge
since the ASUS board was known to have RAM issues..... it actually got me 20 seconds
further into the deploy on Tarkov
😀
- other than that to result
Removed RAM sticks for single and dual, no result
Replaced Motherboard from ASUS to MSI, no result.
Set PCIe back to 3.0 no result
Disabled Precision Boost for CPU -> kinda feels like it improved it
Limited GPU Frequenzy to 1500/1600 starting at 800mV -> enabled me to at least deploy in Tarkov
If i stand on the edge of the Tarkov map and look in - it tends to crash.
If i get into an engagement - it tends to crash.
Maybe someone here has a better guess than me on what might be happening.
My feeling is the power consumption spike of the 3090 is strong enough to
tear the whole system down? Then again its a 1200 Watt PSU and a (supposedly)
good quality one as well. From what i know Tarkov is a CPU heavy game so it could
also be the CPU, Heaven on the other hand is clearly GPU focused.
There have been reports on transient power consumption spikes for the 30-Series
cards which might cause blackscreens, maybe this is the issue here...
My next step is to replace the PSU or even have GPU and CPU/Motherboard
run on 2 different PSUs. I dont think the issue is CPU/GPU health related or caused by bad
memory as i have checked all sticks.
If anyone has had similar experiences with 3090 black screen i would love
to hear other suggestions i can try before i order another 300$ PSU :/
Love and Happiness

When the safety feature on the power supply activates, you need to switch the on/off button to restore normal operation.
Consider connecting the GPU straight to the motherboard. Reason: Some risers were damaged or missing.
Yes, I understand; it would be difficult with a solid loop, but you have to try your best.
OCP usually comes after fans start increasing speed.
Occasionally you have to unplug or disconnect the PSU before and after turning it on for it to function, while other times it works without any action. Regarding your memory purchase, it's unclear if it came in a single package or multiple smaller ones.
RAM was purchased as a quad stack 4x8 GB. That's accurate. Occasionally it becomes unresponsive and I can press the buttons however many times I want, unless I disconnect power completely and that usually forces a full PSU reset with no further action. There are also instances of blackouts where I can simply return to the normal power button and restart the PC. Then there are those cases when the system restarts automatically, typically within 2-3 seconds after the blackout occurs. The GPU was connected directly during initial build and testing, using an air-cooled setup. The riser has been in place for three years now, and since I've used two different risers (PCIe 3 and PCIe 4) to check for issues, I don't believe the problem is there. Thank you very much for your feedback so far!!!! Bunny
Hey, just to complete this thread - i bought a MSI Ai1300P ATX 3.0 PSU and the issues are gone. It seems my old PSU got bad over time. Thank you for ur help!

They gradually deteriorate, which means the output now is reduced compared to when they were acquired in year one. Their aging can accelerate based on the conditions they face. Additionally, with cable extensions, they might need to replace units more often; the increased length results in higher rail voltage drop.
