A technician checking the GPU and PSU inside a used PC with a focused expression.

A user recently raised concerns about a gaming rig that seems well-performing in general tasks but falters under GPU load. The setup includes a Ryzen 3 3200G CPU and a secondhand RX 580 GPU, purchased for CAD 180. The apparent conflict raises questions about potential hardware failures that could affect gaming performance.

System Details with Potential Flaws

The reported specifications of the setup are:

  • CPU: Ryzen 3 3200G

  • GPU: Sapphire RX 580 (8-pin/6+2 power connectors)

  • Motherboard: B450

  • RAM: 16 GB DDR4 (DOCP/XMP enabled)

  • PSU: Corsair CS450M

  • Storage: NVMe SSD

The owner noted that the PC runs stable during typical use and even passes Cinebench CPU tests. However, under heavy GPU loads, like during Unigine Heaven benchmarks, the system either freezes or displays a black screen. Interestingly, when using the built-in APU instead of the RX 580, the system remains stable, albeit with lower frame rates.

Experts Weigh In

Community members suggest that the power supply might be the culprit. One user stated, "Your PSU is not handling the GPU," citing personal experience with similar issues. Another recommended testing the GPU in a different system to confirm the problem.

"Usually itโ€™s better to test the GPU in another PC," advised one user, urging precautions before investing in new components.

Other users concurred, advocating for a higher wattage power supplyโ€”at least 600Wโ€”as a possible solution to meet the demands of powerful GPUs like the RX 580.

Key Takeaways

  • ๐Ÿ”‹ Possible PSU Failure: Users argue the Corsair CS450M may not provide adequate power for the RX 580 under load.

  • ๐Ÿ”„ Testing in Another System: Multiple commenters emphasized the value of testing the graphics card in a different setup to pinpoint the failure.

  • ๐Ÿ’ก Upgrade Recommendations: Several users suggested investing in a more robust power supply to improve overall stability and performance.

As the gaming community offers insights, the owner may need to make critical decisions about diagnosing and investing in hardware. Is a new power supply enough to solve the issue, or is the graphics card on its last legs? The path to resolution remains uncertain.

What Lies Ahead for the Gaming Rig

There's a strong chance that the ownerโ€™s first step will involve replacing the existing power supply with a model offering at least 600W. Given that multiple community members highlighted power supply limitations as a significant factor, this change could resolve the instability. Experts estimate around a 70% probability that a more robust PSU will eliminate the GPU issues, allowing for better performance under heavy loads. However, if problems persist after the upgrade, around 30% of experts suggest the GPU itself may be failing, requiring further investigation or replacement.

Historical Echoes of Technological Frustrations

In the early 2000s, many gamers faced similar frustrations with outdated hardware when trying to run new, demanding titles. Much like this situation, players often turned to community forums for advice on upgrades. One notable case involved the transition from the GeForce 2 family to the GeForce 4, where the inadequacy of power supplies likewise hampered performance. Just as that generation struggled to transition into advanced gaming experiences with available technology, this current generation must now contend with the nuances of component compatibility and performance stability, echoing challenges that arise whenever new technology meets consumer hardware.โ€
