Hi everyone,
I'm using an ASUS TUF Gaming RTX 5090 OC with a Thermal Grizzly WireView Pro II Wired, and I'd appreciate some feedback.
I previously experienced several Current Imbalance FAULT warnings in WireView, particularly when the GPU was drawing around 450–535 W.
I recently disconnected and reseated the power connections on both the PSU cable and WireView side, making sure everything was firmly inserted.
Since doing that, I haven't seen any new Current Imbalance warnings in the screenshots I've captured, although two of the six conductors still consistently carry slightly less current than the others.
I also started lowering the GPU Power Limit using MSI Afterburner, first to 80% and then 75%.
Here are my readings:
| Power Limit |

| 100% |
528.6 W |
7.7 / 6.7 / 6.5 / 7.7 / 8.0 / 7.7 |

| 100% |
519.7 W |

| 75% |
463.0 W |
6.7 / 5.9 / 6.0 / 6.4 / 6.9 / 6.8 |
1.0 A |
| 75% |
457.5 W |
6.8 / 5.9 / 6.0 / 6.4 / 6.6 / 6.5 |
0.9 A |
| 75% |
459.7 W |
6.7 / 5.9 / 5.9 / 6.5 / 6.7 / 6.7 |
0.8 A |
These readings were taken after reseating the connectors. Before that, I had recurring imbalance warnings, but I don't have the exact earlier per-wire readings available for a reliable comparison.
At 75% Power Limit, the GPU is now drawing approximately 460 W, with individual conductor currents between 5.9 and 6.9 A.
The voltage stays around 11.98 V, and WireView's onboard temperatures are around 23–27°C. I understand these are not direct measurements of individual connector contact temperatures.
All WireView fault indicators currently show OK.
My questions:
- Is a difference of approximately 0.8–1.0 A between the highest- and lowest-current conductors normal at around 460 W?
- Should I be concerned that conductors 2 and 3 consistently carry less current than the others?
- Could the previous Current Imbalance warnings have been caused by a connector that wasn't fully seated?
- Does this current distribution look acceptable, or would you recommend replacing the cable or having the connectors inspected?
- Has anyone with an ASUS TUF RTX 5090 and WireView Pro II seen similar readings?
I'm aware that lowering the power lmit reduces current but doesn't necessarily fix a bad electrical connection, correct?
Thanks!
