Gigabyte RTX 5090 AORUS MASTER ICE owner reports burned 16-pin adapter after power was limited to 500W
A user on Mobile01 reports that the bundled 16-pin power adapter for a Gigabyte AORUS MASTER ICE GeForce RTX 5090 burned after the PC began crashing during a gaming session. According to the user, the 16-pin connector on the graphics card itself looked normal at the time of inspection.
What makes this story particularly interesting is that the original poster says they had already been aware of 12V-2×6 connector reports and used only the original cables. He followed an online guide and used MSI Afterburner to cap the graphics card at 500 W.
“I remember I followed an online tutorial and used Afterburner to limit the graphics card to 500W. I will check the details again when I get home. Thanks for the advice.”

The user says the failure happened after about seven months of use, and they are concerned about possible internal damage to the GPU, the power supply, or other components.

We have seen many reports of burned connectors, but I do not recall many cases where the owner also reduced GPU power as a precaution. In this case, the user still ended up with a burned connector after limiting the card. He reduced the power limit from the RTX 5090 default of 575W to 500 W. But it is true that most RTX 5090 cards do not actually use 575W in typical gaming loads, so a 500W cap may not change much in practice. But this user also limited voltage.

The card owner says he will file a warranty claim and push back if the damage is blamed on “user error,” pointing to how many similar cases have been posted online.
