Problem occurs when PC loses connection following GPU activity decline during intense tasks
Problem occurs when PC loses connection following GPU activity decline during intense tasks
Hi everyone!
I own a PC that I assembled some time ago and have been using smoothly for a while.
Over time, I noticed a problem where the screen would go dark and alert me about a lost connection during heavy GPU usage. After investigation, I realized this occurs when the GPU's demand stays high even though the system's needs stay constant—like when rendering, the GPU usage stays around 99% for a while before gradually dropping to between 70-80%, taking seconds to a minute. Eventually, the PC shuts down.
I could still hear apps running and I managed to talk on Discord, but the screen was black. A quick power cycle usually resolves it.
However, if I correctly diagnose this as the GPU needing more power than available, my suspicion shifts to older wiring in a building that hasn’t been renovated yet. It seems the GPU might lose its ability to get the required power when overall power demand rises. That’s possible?
While it makes sense that the PC would semi-reboot when the GPU lacks sufficient power, I’m curious if there are any solutions I can try.
I have no background in power supplies or electricity, but from what I understand, this could simply be the GPU demanding more than it receives.
I attempted to move the power supply into a different outlet in my apartment, but it didn’t help. Perhaps a dedicated battery for the GPU or a special setup could provide temporary power? Or maybe there’s a simple ritual I could perform to help?

What's the age of your PSU?
GPU: NVIDIA GeForce RTX 3070
The issue here is that your PSU may not meet the requirements, even if it's brand new. This is because the RTX 3000 series is known for significant power spikes, often leading to shutdowns or failures (your choice).

This is why those who upgraded to the RTX 3000 series were advised to overprovision their PSU's capacity and also invest in a stable unit. You might consider obtaining a well-built 850W or higher model, or checking if your wall outlet is functioning properly before proceeding.
