Korean outlet QuasarZone tested the GeForce RTX 5090 Founders Edition running Cyberpunk 2077 at 4K with DLSS 5 enabled, recording peak power draw near 650W and a 16-pin (12VHPWR) connector temperature of 91.7 degrees Celsius, higher than the GPU die itself. The RTX 5080 also showed a temperature rise with DLSS 5 on, though smaller in magnitude than the 5090's.
Brazilian YouTube channel TecLab modified a Galax HOF OC LAB RTX 5090 to run on three 8-pin Mini-Fit Jr. power connectors instead of Nvidia's dual 16-pin design, by rewiring the Sense 0 and Sense 1 pins to fool the card into recognizing the new configuration. The card still hit its full 575W TDP and ran stable at 3.4GHz across load tests up to 900W and 120A peak current, with temperatures staying around 35°C and no firmware changes needed.
A HardOCP forum user reported that their MSI RTX 5090 Gaming Trio OC suffered a melted 16-pin power connector after testing Nvidia's new DLSS 5 feature in NBA 2K27, currently the only game with official support. The user's monitoring software showed sustained power draw above 610W, more than 150W higher than the card's typical 450W gaming load, before the connector overheated and several pins were visibly scorched.
