What are the peak power consumption levels for the RX 9070 XT Red Devil and RX 7900 XTX Red Devil

PowerColor Red Devil Radeon RX 9070 XT

- Peak Power Consumption: The RX 9070 XT Red Devil requires a minimum power supply of 900 watts, which is identical to the requirement for the RX 7900 XTX Red Devil[1][3][4]. This high power requirement is due to its 3.0 GHz boost clock and the inclusion of three 8-pin power connectors, which provide ample headroom for overclocking and maintaining performance under demanding loads[4][7].
- System Requirements: The 900-watt power supply requirement applies to the entire system, not just the GPU, indicating that the system should be capable of delivering at least 75A on the 12V rail[3].

PowerColor Red Devil Radeon RX 7900 XTX

- Peak Power Consumption: The RX 7900 XTX Red Devil also requires a minimum power supply of 900 watts, which is about 100 watts more than AMD's official recommendation for the standard RX 7900 XTX model[1][3]. The standard model typically requires an 800-watt power supply[3].
- System Requirements: This high power requirement is consistent with the card's high performance capabilities, including a TDP of 355 watts and the use of three 8-pin power connectors[2][5].
- Real-World Usage: In practical scenarios, a system with the RX 7900 XTX Red Devil can pull around 600 watts from the power supply under heavy loads, assuming a 90% efficiency rate, which is close to the recommended minimum PSU capacity[5].

Both cards are designed for extreme performance and require robust power supplies to ensure stable operation, especially when overclocked.
