Nvidia’s RTX 5090 is reportedly a 600W MONSTER!

Tonnes of power! – Nvidia’s RTX 5090 is reportedly a power-hungry 600W GPU

Following on from today’s RTX 50 series power draw rumours, it has now been claimed that Nvidia’s upcoming RTX 5090 is a colossal 600W graphics card. This claim again comes from @Kopite7kimi, who appears to have confirmed the power targets of Nvidia’s RTX 5080 and RTX 5090 GPUs.

If this report is true, Nvidia’s RTX 5090 will effectively max out the potential of the 12V-2×6 (16-pin) GPU power standard. It is designed to deliver a maximum of 600 watts of power. While PCIe power can deliver up to 75 watts of additional power, Nvidia’s RTX 5090 has will push today’s power cables to their limits. As crazy as it sounds, many RTX 5090 GPUs may feature dual 12V-2×6 power connectors to enable heavy overclocking.

With a TDP of 400 watts, Nvidia’s RTX 5080 will only consume 50 watts less than an RTX 4090. Assuming Nvidia has increased their power efficiency, this should allow Nvidia’s RTX 5080 to match or surpass today’s RTX 4090. Even so, it remains to be seen how Nvidia’s RTX 50 series will perform compared to their predecessors.

With a 600W power draw, Nvidia’s RTX 5090 will require a colossal cooler. Basically, Nvidia need to find a way to dissipate 150W of additional heat. This may present a problem for Nvidia’s AIB partners. After all, they will all need to invest in beefier GPU heatsinks and more robust power delivery systems.

If this report is true, Nvidia’s RTX 5090 will consume more power than traditional gaming PCs by itself. This alone will push PSU manufacturers to create more higher-wattage units. After all, there needs to be an insanity-tier PSU that’s ready to power someone’s inevitable dual RTX 5090 workstation.
