This leaves around 60W that is used by everything else on the board, the fans, lighting, Video output ports, PCIe communications, and inefficiency losses in the various VRM stages. We see the card max out at ~360W, with around 80W of that consumed by the 10GB of GDDR6X itself and roughly 220W consumed by the GPU core. New to the RTX 3000 series cards are some detailed power measurement readouts available to programs like GPUz. We’ll have to test this more in-depth once we see some RTX I/O enabled titles hit the market, as reduced PCIe bandwidth could certainly make an impact there. Nvidia is preparing for RTX I/O, it needs to make sure it has several GB/s available to pull data directly from your high-speed NVMe drives without negatively impacting the performance of the card. With as ridiculously powerful as this card is, that’s pretty much unnoticeable. ![]() Even dropping clear down to PCIe 3.0 x8 is going to lose you less than 2% performance. As you can see, PCIe bandwidth isn’t much of an issue for gaming. ![]()
