Key Takeaways
1. Another case of a burnt power connector on an MSI RTX 5090 GPU has been reported, adding to existing incidents in the RTX 50 Series.
2. The damage includes burnt and melted connection points on the GPU’s power connector and the PSU cable, with visible deterioration at the PSU end.
3. The affected GPU was used for about a month at stock settings without any overclocking.
4. The PSU cable was a stock 12VHPWR cable from a Corsair SF1000L, chosen due to concerns over custom cables.
5. The 12VHPWR connector is rated for 600W, matching the RTX 5090’s power draw, raising concerns about inadequate load balancing in the GPU series.
There has been another incident involving a burnt power connector on an RTX 50 series GPU, according to reports. A Reddit post highlights the burnt power connector on an MSI RTX 5090, along with damage to the cable at the PSU end. This case adds to the list of burnt connector problems documented in the RTX 50 Series 12VHPWR Megathread, bringing the confirmed total to five. The GPU was bought around a month ago and was functioning without any overclocking.
Details of the Incident
In the post by user ‘Roachard’, the damage to their MSI 5090 GAMING TRIO OC’s power connector is clearly visible, with several burnt and melted connection points, plus burnt pins on the PSU cable. Notably, the cable also shows damage at the PSU end. The user mentioned that it was a stock PSU 12VHPWR cable that came with the Corsair SF1000L, chosen specifically due to other reports of melting issues with custom cables.
Examination of the Damage
The plastic connector on the PSU side has a noticeable bulge, and the cable appears to have burnt white. It remains uncertain if that specific port on the PSU is now dysfunctional or if the PSU itself has sustained damage. Roachard noted that the GPU was acquired approximately a month ago and was being operated at stock settings.
Technical Insights
The setup included an Asus Strix B650E-I motherboard paired with a Ryzen 7 9800X3D CPU. Comments on the post suggest that the issue might stem from inadequate load balancing on the RTX 40 and 50 series GPUs. Additionally, the 12VHPWR is rated for a maximum power delivery of 600W, which matches the power draw of the RTX 5090 under load, leaving little to no headroom for safety.
