The RTX 5070 Ti and RX 9070 XT have nearly identical manufacturer power ratings and the same recommended PSU capacity for their reference specifications. In two independent gaming comparisons, however, the RX 9070 XT used more power on average. What that means for your electricity bill depends on your gaming hours and local rate—not just the wattage printed on a product page.
What do the manufacturers’ power figures mean?
NVIDIA lists the reference RTX 5070 Ti at 300 W Total Graphics Power (TGP) and recommends a 750 W system power supply. AMD lists the RX 9070 XT at 304 W Typical Board Power (Desktop) and a 750 W minimum PSU recommendation. These are the manufacturers’ published specifications, not measurements made under a shared test method.

How much power do they use while gaming?
Game draw can differ from a specification-sheet figure because it depends on the game, settings, frame rate, card design and measurement method. In its 2025 review testing, PC Gamer reported average card power of 303 W for the RTX 5070 Ti and 352 W for the RX 9070 XT. TechSpot’s 52-game comparison, published May 22, 2026, summarized the Radeon as typically using about 20% more power. Those are review results, not a guarantee for every game, partner card or PC configuration.
#1 Best Overall
- Fully Modular PSU: Reliable and efficient, low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs.
- Intel ATX 3.1 Certified: Compliant with the ATX 3.1 power standard, supporting PCIe 5.1 platform withstands 2x transient power excursions from the GPU.
- Keeps Quiet: A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load.
- 105°C-Rated Capacitors: Delivers steady, reliable power and dependable electrical performance.
- Modern Standby Compatible: Extremely fast wake-from-sleep times and better low-load efficiency.
Sources: PC Gamer’s 2025 comparison and TechSpot’s 52-game comparison. These reported figures are card-power results; they should not be read as whole-PC wall-power measurements. A wall meter includes the rest of the system and the power supply’s conversion losses. Idle use, transient peaks and equal-frame-rate comparisons are separate questions, and the cited average figures do not settle them.
What PSU do you need?
For their reference specifications, both companies give a 750 W PSU recommendation. That shared figure means choosing between these two reference GPUs alone does not change the nominal PSU capacity on paper. It is not a guarantee that every 750 W unit will suit every build.
Rank #2
- ATX 3.1 and PCIe 5.1 Support: Fully compatible with Intel ATX 3.1 specifications, with native PCIe 12V-2x6 (12+4 pin) connectors for modern GPUs.
- 80 PLUS Gold Efficiency: Provides up to 90% efficiency, reducing energy consumption and heat output during operation.
- Smart Zero Fan Technology: Automatically adjusts fan speed based on load, minimizing noise during low-load operations.
- Fully Modular Design: Includes low-profile flat black cables, making cable management easier and improving airflow inside your case.
- High Amperage Single +12V Rail: Provides reliable and stable power delivery, optimized for high-end gaming and workstation builds.
- RTX 5070 Ti: NVIDIA lists either two PCIe 8-pin cables used with the included adapter, or a PCIe Gen 5 cable rated for at least 300 W. NVIDIA recommends a PCIe CEM 5.1-compliant PSU. Its 750 W figure is based on a system configured with a Ryzen 9 9950X, and NVIDIA notes that requirements can vary with system configuration.
- RX 9070 XT: AMD lists a 750 W minimum PSU recommendation. Check the connector and power instructions for the specific retail card; do not assume every partner model uses the same arrangement.
Before reusing or buying a PSU, check the exact graphics card maker’s instructions, the CPU and other components in your build, the PSU’s quality and condition, and whether it has the required native cables. NVIDIA also cautions that specifications may vary by add-in-card manufacturer. A partner card’s own product sheet takes precedence over a family-level reference figure.

How much could the power difference cost to run?
Calculate GPU energy use from its average draw, your hours of use and your electricity rate:
Rank #3
- 80 PLUS GOLD CERTIFIED
- 10-year limited warranty, guaranteeing long term reliable operation
- Fully modular design
- ATX 3.1 & PCIE 5.1
Energy (kWh) = average power (W) ÷ 1,000 × hours used
Cost = energy (kWh) × your electricity price per kWh
Rank #4
- 80 PLUS Gold Certified: Delivers up to 90% energy efficiency under typical loads, reducing power consumption and heat generation
- ATX 3.1 & PCIe 5.1 Ready: Fully compliant with the latest standards, ensuring compatibility with next-generation components
- Native 12V-2x6 Connector: Features a dual-color design for safer and more reliable power delivery to modern graphics cards
- Low-Noise Operation: Equipped with a quiet 120mm fan that provides effective cooling while maintaining minimal acoustic levels

For an illustration using PC Gamer’s reported averages, the gap between the two cards is 49 W, or 0.049 kWh per hour. Across 1,000 gaming hours, that is 49 kWh. At an assumed $0.20 per kWh, the difference would be $9.80 for those 1,000 hours. The rate is an example input, not a claim about a current or universal electricity price.

Why can your card or results differ?
Specifications and benchmark averages describe particular products or test conditions, not every configuration. NVIDIA says system requirements can differ by configuration, and both vendors’ reference figures may not match a partner card’s design. Game engine, resolution, settings, frame-rate limits and test method can all change observed draw.
For a comparison specific to your PC, look for measurements that identify whether they record card power or wall power, name the games and settings, and explain whether frame rates are capped or matched. Do not multiply a card-power figure into a whole-system bill without accounting for the rest of the PC.
