RTX 5090 owner reports explosive capacitor failure on PNY GeForce RTX 5090 ARGB OC, bending heatsink fins
Explosions on modern graphics cards are exceptionally rare, but one PNY GeForce RTX 5090 ARGB OC has made headlines after a late-night failure that sounded like a firecracker. According to the user’s account, the system was under light load while editing video, GPU temperatures were below 70°C, and everything appeared normal—right up until a loud pop, sparks, smoke, and a strong electrical smell filled the room.
Photos shared by the owner show a capacitor near the 16-pin (12VHPWR) power connector that appears to have ruptured with enough force to bend adjacent heatsink fins. Notably, the 16-pin connector itself reportedly remained intact. The system was powered by a Super Flower Leadex III 1300W 80+ Gold PSU using the native 12VHPWR cable supplied with the power supply, not a third-party adapter.
While the root cause hasn’t been confirmed, several plausible scenarios were discussed by the community:
– A defective or marginal-quality capacitor that failed under normal operating conditions
– A soldering or assembly defect that led to localized stress or shorting
– Direct or overly close contact between the capacitor and the heatsink, potentially transferring heat into the component and accelerating failure
It’s important to note that NVIDIA provides the GPU and memory modules, while board partners design the PCB, choose supporting components, and assemble the card. Without a formal analysis, it’s impossible to assign definitive blame, and this appears to be an isolated case. Still, for a flagship card in the $2,000-plus range, a catastrophic component failure is alarming and warrants investigation.
The owner reports that the RMA was approved, which should at least make the situation right for that customer. However, the incident raises understandable questions about component selection and quality assurance for this specific model. Some users also pointed out that if the capacitor was making contact with the heatsink, thermal transfer or vibration could have contributed to premature failure. Others noted that while melting or mis-seated 16-pin connectors have been the most common power-related issue on high-end GPUs in recent years, an exploding capacitor is a different and far more dramatic symptom.
What RTX 5090 owners can do right now
– Ensure the 12VHPWR cable is fully seated with no visible gap and minimal cable strain at the connector
– Check for clearance between components and the heatsink; nothing should be touching that isn’t designed to
– Maintain good case airflow to keep hotspots in check
– Avoid questionable adapters; use high-quality, native 12VHPWR cables from reputable PSUs
– If you ever smell burning electronics, hear a sharp pop, or see smoke, power down immediately and unplug the system
– If in doubt, contact the card maker’s support for inspection or RMA
At this stage, the incident appears to be a one-off, but it’s a reminder that even top-tier GPUs can encounter rare hardware failures. An official teardown or statement would go a long way toward clarifying whether this was a singular defect or something that requires a design or process adjustment. Until then, users can reduce risk with careful cable management, proper clearance, and attentive system monitoring.
