What PSU do I need for a GeForce RTX 5070 Ti?

750 W to 750 W, depending on the processor beside it. With a Ryzen 7 7800X3D the answer is 750 W.

Where the watts go — Ryzen 7 7800X3D with GeForce RTX 5070 Ti

Power draw by component for a GeForce RTX 5070 Ti build
Component Power
Ryzen 7 7800X3D at its ceiling 162 W
GeForce RTX 5070 Ti board power 300 W
Motherboard 25 W
Memory module x2 6 W
NVMe SSD 7 W
Case fan x3 6 W
Continuous draw 506 W

The recommendation of 750 W sits that draw at 67% of the supply's rating. The target is 80%: supplies lose capacity as they age, and a graphics card's millisecond transients have to come from somewhere.

Why the answer is a range

A GeForce RTX 5070 Ti is rated at 300 W of board power, and NVIDIA recommends a 750 W supply for it. That single figure has to cover every processor anyone might pair with the card, which is why the honest answer depends on yours: across the 26 processors here this card needs anywhere from 750 W to 750 W.

With a Ryzen 7 7800X3D the whole system draws 506 W at once — 300 W for the card, 162 W for the processor at its power ceiling, and 44 W for the board, memory, drives and fans. That calls for 750 W, leaving the supply at 67% of its rating rather than sitting on top of it.

Frequently asked questions

What PSU do I need for a GeForce RTX 5070 Ti?
Between 750 W and 750 W depending on the processor. With a Ryzen 7 7800X3D the answer is 750 W: the system draws 506 W at full load, and that leaves the supply at 67% of its rating.
How many watts does a GeForce RTX 5070 Ti use?
300 W of total board power under load. That is the card alone — a complete system adds the processor's ceiling and roughly 44 W for the motherboard, memory, drives and fans.
NVIDIA recommends 750 W. Why does this page sometimes say more?
Because a card maker publishes one figure per card and it has to work with any processor. On this card no processor here pushes past it. Where the build needs less, the recommendation stays at the vendor's number.
Is a 750 W PSU enough for a GeForce RTX 5070 Ti?
Yes, for every processor in this table. It is NVIDIA's own recommendation and no pairing here exceeds it.

A sizing estimate, not a measurement. It adds the processor's power ceiling, the graphics card's rated board power and an itemised allowance for the rest of the system, then leaves headroom so the supply is not running at its limit. Real draw depends on the board's power profile, how far the parts are overclocked, and how a particular graphics card handles transient spikes. Treat a result within 50 W of a supply's rating as a reason to choose the next size up.
