What PSU Do You Need for the NVIDIA GeForce RTX 5070 Ti?

Recommended wattage, the realistic minimum, and the connector you need — with a live peak-draw estimate.

Why 750W and not less?

The NVIDIA GeForce RTX 5070 Ti has a board power of about 300W, but it can spike well above that for milliseconds at a time. Add a typical gaming CPU and the rest of the system, then keep the supply in its efficient 50-80% load band, and 750W is the comfortable target. The NVIDIA GeForce RTX 5070 Ti uses a 16-pin 12V-2x6 connector, so an ATX 3.0/3.1 power supply with a native 12V-2x6 cable is strongly recommended — it removes the fragile adapter and is rated to ride out the card’s transient spikes without tripping.

Frequently asked questions

What power supply do I need for the NVIDIA GeForce RTX 5070 Ti?

A 750W 80+ Gold unit is the recommended choice; it covers the card’s peak draw plus a transient-safe buffer and keeps the PSU in its efficient load band. 700W is the realistic minimum for a single-GPU build.

Is a 700W PSU enough for the NVIDIA GeForce RTX 5070 Ti?

It can run a modest build, since the card itself peaks around 300W, but it leaves little headroom for a power-hungry CPU or transient spikes. Stepping up to 750W is the safer, quieter long-term choice.

Does the NVIDIA GeForce RTX 5070 Ti need an ATX 3.0 power supply?

Yes — it uses a 16-pin 12V-2x6 connector, and an ATX 3.0/3.1 unit provides the native cable and the transient-spike rating these cards expect.
