What 220 W means for this card

At the 85% load these figures assume, a GeForce RTX 4070 SUPER draws about 187 W in a game, and a machine built around it about 307 W from the wall. At California's average electricity price that comes to $209 a year, of which the card itself accounts for $106.

What stands out about the GeForce RTX 4070 SUPER

The same rated power as the RTX 3070.
The RTX 4070 SUPER and the RTX 3070 are both rated at 220 W, so on these figures a machine built around either costs exactly the same to run.
Less memory than the closest AMD card by rated power.
The RX 9070 is rated at 220 W to this card's 220 W, but carries 16 GB of graphics memory against the RTX 4070 SUPER's 12 GB.

Building around the GeForce RTX 4070 SUPER

NVIDIA suggests a 650 W power supply. With any of the 26 processors in the PSU calculator, a build with this card needs 650 W.

Frequently asked questions

How much power does the GeForce RTX 4070 SUPER use?

Its Total Graphics Power is 220 W, which is the limit rather than the average. At a realistic 85% sustained load a demanding game pulls around 187 W from the card, and roughly 307 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 4070 SUPER?

At the US average of 19.42 cents per kWh, 4 hours of gaming and 6 idle hours a day works out at about $209 a year for the whole machine in California, $79 in Nevada and $317 in Hawaii. The card's own share of that is roughly $106.

What power supply does a GeForce RTX 4070 SUPER need?

NVIDIA recommends 650 W. The card plus a mainstream system peaks around 340 W, so that recommendation leaves about 310 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 4070 SUPER it takes 17.5 idle hours to cost as much as 4 hours of gaming, which a machine left on around the clock passes comfortably.

Estimates for informational purposes only. Total Graphics Power is a power limit, not an average: real draw depends on the game, resolution, frame cap, board partner design and any factory overclock. Electricity prices are state residential averages and your tariff will differ.
