DLSS 5 pushes RTX 5090 power to the edge, melts a connector during testing
DLSS 5 Neural Rendering appears to significantly raise RTX 5090 power draw, with the first reported melted 12V-2x6 connector on an MSI RTX 5090 Gaming Trio OC during NBA 2K27 testing. GPU-Z logged about 613.5 W board power (above MSI’s 575 W rating), and a burning smell revealed the connector melted to the socket; note that total board power includes PCIe slot power, so the connector’s load may not reflect the entire draw. NVIDIA has not commented, but this incident suggests DLSS 5 could push sustained power near or beyond the connector’s limits, though one case isn’t proof of a broader issue.
