Key Takeaways
1. A Reddit user reported a malfunctioning RTX 5080, highlighting potential issues in the RTX 50 series.
2. The RTX 5080 showed a red light warning, indicating a cable connection issue, leading to reduced GPU performance.
3. Damage was found at the PSU end of the 12VHPWR connector, though not as severe as issues with the RTX 5090.
4. Tests revealed RTX 50 series cards could reach extremely high temperatures and draw excessive current, suggesting design flaws.
5. Concerns over the reliability of RTX 5090 and 5080 may lead buyers to consider alternative options like the RX 9070 XT.
If the issues with the spontaneously combusting Ryzen 7 9800X3D and GeForce RTX 5090 power connectors weren’t enough, there’s a new problem on the horizon. A Reddit user recently shared their experience with a malfunctioning RTX 5080, which has almost half the thermal design power (TDP) of the RTX 5090.
The Discovery of a Problem
User u/Ambitious_Ladder1320 realized something was wrong when their GeForce RTX 5080 began flashing a red light, an indicator often linked to a cable connection issue. After re-seating the cable and rebooting their system, the warning light disappeared; however, the GPU performance dropped to PCIe Gen3 speeds. Consequently, their display’s refresh rate and resolution were noticeably lower. A closer look revealed significant damage at the PSU end of the 12VHPWR connector, though it was not as severe as the issues seen with the earlier RTX 5090.
Design Flaws in the RTX 50 Series
This points toward a possible design flaw in the RTX 50 series, especially since Der8auer’s tests showed that the cards could reach temperatures of 150 degrees Celsius and pull as much as 22 Amperes of current—much higher than the wire’s specifications allow. Gamer’s Nexus has also jumped in to examine the situation, offering to purchase the PSU, cable, and the RTX 5080 for further investigation.
User Error or Serious Concern?
We will have to wait and see if this is a matter of user mistake, a theory proposed by at least one Redditor. Regardless, this raises red flags for anyone considering buying an RTX 5090 or 5080. However, acquiring one of these cards is nearly impossible right now. It might be wiser to hold out for the RX 9070 XT, and with a bit of luck, you could even get your hands on the 32 GB version later this year.
