What 360 W means for this card

At the 85% load these figures assume, a GeForce RTX 5080 draws about 306 W in a game, and a machine built around it about 426 W from the wall. At California's average electricity price that comes to $269 a year, of which the card itself accounts for $167.

What stands out about the GeForce RTX 5080

A generation on from the RTX 4080.
Against the RTX 4080, a generation earlier: 40 W more rated power (360 W against 320 W), the same 16 GB of memory and about $10 more a year to run at the US average.
Less memory than the closest AMD card by rated power.
The RX 7900 XTX is rated at 355 W to this card's 360 W, but carries 24 GB of graphics memory against the RTX 5080's 16 GB.
Room for 11 of the 20 open models in the local-LLM dataset.
With Q4_K_M weights and an 8K context, its 16 GB holds models up to Qwen2.5 14B. The local-LLM page for the RTX 5080 covers every model at every quantisation and context length.

Building around the GeForce RTX 5080

NVIDIA suggests an 850 W power supply. With any of the 26 processors in the PSU calculator, a build with this card needs 850 W.

Frequently asked questions

How much power does the GeForce RTX 5080 use?

Its Total Graphics Power is 360 W, which is the limit rather than the average. At a realistic 85% sustained load a demanding game pulls around 306 W from the card, and roughly 426 W from the wall once the rest of the machine is counted. NVIDIA recommends a 850 W power supply.

How much does it cost to run a GeForce RTX 5080?

At the US average of 19.42 cents per kWh, 4 hours of gaming and 6 idle hours a day works out at about $269 a year for the whole machine in California, $102 in Nevada and $409 in Hawaii. The card's own share of that is roughly $167.

What power supply does a GeForce RTX 5080 need?

NVIDIA recommends 850 W. The card plus a mainstream system peaks around 480 W, so that recommendation leaves about 370 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 5080 it takes 24.3 idle hours to cost as much as 4 hours of gaming — more than fits in a day, so on this card gaming always dominates.

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.
