Where the watts go
| Item | Power | Per year | Cost / year |
|---|---|---|---|
| Gaming hours | 609 W | 888.8 kWh | $173 |
| Idle hours | 70 W | 153.3 kWh | $30 |

What 575 W means for this card
At the 85% load these figures assume, a GeForce RTX 5090 draws about 489 W in a game, and a machine built around it about 609 W from the wall. At California's average electricity price that comes to $362 a year, of which the card itself accounts for $259.
What stands out about the GeForce RTX 5090
A generation on from the RTX 4090.
Against the RTX 4090, a generation earlier: 125 W more rated power (575 W against 450 W), 8 GB more memory (32 GB against 24 GB) and about $30 more a year to run at the US average.
The highest rated power of the 34 cards here.
At 575 W, a machine built around the RTX 5090 costs about $202 a year to run at the US average — $111 more than one built around the lowest-rated card, the RTX 4060.
The most graphics memory of the 34 cards here.
Its 32 GB is 8 GB more than the next largest amount in the dataset, 24 GB.
Room for 17 of the 20 open models in the local-LLM dataset.
With Q4_K_M weights and an 8K context, its 32 GB holds models up to Mixtral 8x7B. The local-LLM page for the RTX 5090 covers every model at every quantisation and context length.
Some builds need more than the 1,000 W supply NVIDIA suggests.
Paired with the Core i9-14900K, the whole build calls for 1,200 W; 10 of the 26 processors in the RTX 5090 PSU table take the requirement above 1,000 W.
