The GeForce RTX 4090 is the most power-thirsty consumer GPU ever made, and that can have consequences.
Posting on the NVIDIA subreddit, /u/reggie_gakil simply says his ” RTX 4090 Adapter burned .” He shared a picture of the card and of the adapter, both of which are reproduced here. In the thread, he comments that he was playing Red Dead Redemption 2 when it happened, and remarkably, the card itself is still functional, although he intends to RMA it regardless.
Both NVIDIA as well as CableMod reached out to the user in the thread. NVIDIA spoke to him in DM, so we have no idea what they were discussing, but CableMod offered to replace the user’s adapter for him.
That’s supported by the guide from CableMod, who says to give at least 3.5cm of clearance before bending the 12VHPWR cables vertically, and to never bend them horizontally at all. That makes cable routing a little difficult in most cases, where the GPU’s power connector and the pass-through for the cable routing plates aren’t likely to match up exactly on either axis.
