Nvidia's RTX 4090 shipped with a 12VHPWR power connector that Nvidia itself confirmed had melted in roughly 50 known cases by November 2022, prompting a class-action lawsuit alleging a serious electrical and fire hazard, with the connector's sensitivity to partial seating identified as the root cause.
Make your guess on the slip to reveal the answer- "The RTX 4090's 12VHPWR power connector is a safe, reliable standard for high-wattage graphics cards."✕ FALSE
BUYING THE HYPE
▸ HYPE VS REALITY
Nvidia marketed the RTX 4090 as its flagship, top-of-the-line graphics card, sold at $1,599 with a redesigned 12VHPWR power connector intended to be a safe, reliable standard for high-wattage GPUs going forward.
Within weeks of the October 2022 launch, real reports of the 12VHPWR connector melting or burning began appearing, with Nvidia confirming around 50 known cases globally by November 2022 and community-tracked reports continuing well beyond that. A class-action lawsuit alleged Nvidia sold the card with 'a defective and dangerous power cable plug and socket' posing 'a serious electrical and fire hazard.' Independent investigation found the connector required precise, full seating to avoid the failure, with an estimated failure rate around 0.04% -- a small percentage, but on a card sold in large volumes, translating to a real number of actual melted connectors and at least one widely reported case where a pet cat alerted its owner to a smoking, melting connector.
A 'safe, reliable' power standard shouldn't produce real, repeated, independently documented cases of connectors melting and catching fire, even at a low failure rate -- a fire hazard is a fire hazard regardless of how rare, and a real lawsuit and Nvidia's own acknowledged case count confirm this wasn't isolated user error alone. The connector's design being unusually sensitive to partial seating is itself a real design weakness worth knowing about before spending $1,599.
This verdict would change if new, independently verifiable evidence emerged directly supporting the claim "The RTX 4090's 12VHPWR power connector is a safe, reliable standard for high-wattage graphics cards." — evidence stronger than what's currently on record contradicting it.

▸ FAQ
Did RTX 4090 power connectors really catch fire?
Yes, in documented real cases -- Nvidia confirmed roughly 50 known melting incidents by November 2022, and reports of connector melting continued afterward, including at least one case where a pet alerted its owner to a smoking connector.
What caused the RTX 4090 connector to melt?
Investigation found the 12VHPWR connector needed to be fully and precisely seated to avoid the failure; the adapter's design made improper insertion easy to do unknowingly.
