What power supply does the NVIDIA GeForce RTX 5070 Ti need?
The NVIDIA GeForce RTX 5070 Ti draws 285 W on its own. Here is what that means for the supply you buy, and why the answer is not simply that number.
650 W
For a complete system drawing about 440 W under load.
Where the watts go
| Graphics card | 285 W |
|---|---|
| Processor (mid-range estimate) | 105 W |
| Board, memory and storage | 50 W |
| System under load | 440 W |
The recommendation adds 25% over measured draw. That is not padding: a supply run near its ceiling sits in the least efficient part of its curve, and graphics cards draw in microsecond spikes well above their rated figure.
