A quick peek at the GPUz readout for those curious.

Power consumption

New to the RTX 3000 series cards are some detailed power measurement readouts available to programs like GPUz. We see the card max out at ~360W, with around 105W of that consumed by the 24GB of GDDR6X itself and roughly 200W consumed by the GPU core. This leaves around 55W 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. Our system consumed a maximum of 560W from the wall, or around 515W from the PSU itself. Minus the GPU, this leaves us at around 155W from the rest of the system, which is about right. We’ll wager these readings are pretty accurate.

Clock Speeds

From GPUs above, we see the RTX 3090 Trinity top out at 2010Mhz on the core, with it hovering around 1900 MHz steady state out of the box.
