PC Build - Help Requested

[Radegast74]

I read a good article about the rumors swirling over the 5090 power requirements:

VideoCardz reports that the 5090's thermal design power (TDP) will be set at 575 W, up from 450 W for the already power-hungry RTX 4090. The RTX 5080's TDP is also increasing to 360 W, up from 320 W for the RTX 4080 Super.


That also puts the RTX 5090 close to the maximum power draw available over a single 12VHPWR connector, which is capable of delivering up to 600 W of power (though once you include the 75 W available via the PCI Express slot on your motherboard, the actual maximum possible power draw for a GPU with a single 12VHPWR connector is a slightly higher 675 W).

Looks like we will potentially need a new generation of motherboards at some point, just to meet the power requirements for these newer video cards!

Rumors say next-gen RTX 50 GPUs will come with big jumps in power requirements

We’ll likely find out more about Nvidia’s next GPUs at CES next week.
