What 290 W means for this card

At the 85% load these figures assume, a GeForce RTX 3070 Ti draws about 247 W in a game, and a machine built around it about 367 W from the wall. At California's average electricity price that comes to $239 a year, of which the card itself accounts for $136.

What stands out about the GeForce RTX 3070 Ti

A generation before the RTX 4070 Ti.
Against the RTX 4070 Ti, a generation later: 5 W more rated power (290 W against 285 W), 4 GB less memory (8 GB against 12 GB) and about $1 more a year to run at the US average.
Less memory than the closest AMD card by rated power.
The RX 9070 XT is rated at 304 W to this card's 290 W, but carries 16 GB of graphics memory against the RTX 3070 Ti's 8 GB.
Some builds need more than the 650 W supply NVIDIA suggests.
Paired with the Core i9-14900K, the whole build calls for 750 W; 10 of the 26 processors in the RTX 3070 Ti PSU table take the requirement above 650 W.

Building around the GeForce RTX 3070 Ti

NVIDIA suggests a 650 W power supply. Across the 26 processors in the PSU calculator, a build with this card needs 650 W with the Ryzen 5 9600X and up to 750 W with the Core i9-14900K.

Frequently asked questions

How much power does the GeForce RTX 3070 Ti use?

Its Total Graphics Power is 290 W, which is the limit rather than the average. At a realistic 85% sustained load a demanding game pulls around 247 W from the card, and roughly 367 W from the wall once the rest of the machine is counted. NVIDIA recommends a 650 W power supply.

How much does it cost to run a GeForce RTX 3070 Ti?

At the US average of 19.42 cents per kWh, 4 hours of gaming and 6 idle hours a day works out at about $239 a year for the whole machine in California, $90 in Nevada and $363 in Hawaii. The card's own share of that is roughly $136.

What power supply does a GeForce RTX 3070 Ti need?

NVIDIA recommends 650 W. The card plus a mainstream system peaks around 410 W, so that recommendation leaves about 240 W of headroom — deliberate, because transient spikes on modern cards briefly exceed the rated limit.

Do idle hours matter?

More than most people expect. A PC left on but not gaming still draws roughly 70 W whatever card is installed, so the idle bill is flat while the gaming one is not. Over 6 hours a day that is $53 a year in California. On a GeForce RTX 3070 Ti it takes 20.9 idle hours to cost as much as 4 hours of gaming — more than fits in a day, so on this card gaming always dominates.
