About this tag
The gpu power tag collects WindowsForum.com discussion of how much electricity modern graphics cards draw and how that load is delivered through the cable and connector. Coverage centers on the 16-pin 12V-2x6 connector used by high-end cards such as the RTX 5090, including measured connector temperatures and peak wattage under sustained 4K gaming with DLSS enabled. The recurring theme is margin: how close flagship GPUs run to their rated power limits, how short spikes push past them, and what that means for connector heating, melting reports, and safe cabling in a desktop PC.

    RTX 5090 DLSS 5 Test Drives 12V-2x6 Connector to 91.7°C

    Korean hardware site QuasarZone ran a 20-minute Cyberpunk 2077 test at 4K with DLSS 5 turned on. On its RTX 5090 Founders Edition, the 12V-2×6 power connector reached 91.7°C, up from 80.9°C with DLSS 5 off, and power into the 16-pin input peaked at 646.7 W. That is one test on one set of cards...
