The new Radeon RX 9060 XT promises high-end 1440 p performance in a compact, single-8-pin form factor—but its advertised 160 W TDP only tells part of the story. Spikes during ray-traced gaming, CPU pairings such as Ryzen 7 9700X or Core i7-15700K, and common builder habits like enabling Smart Access Memory or mild GPU overclocking all push total system demand well above the spec sheet.

Is a 550W Power Supply Truly Sufficient?

A comprehensive guide for PC builders

Choosing the appropriate Power Supply Unit (PSU) for a new graphics card can be one of the most critical and often perplexing decisions for PC builders. This is particularly true with the introduction of new hardware like AMD's Radeon RX 9060 XT. While manufacturers provide baseline specifications, these figures frequently do not encompass the full spectrum of real-world power demands, especially concerning transient power spikes that can challenge even seemingly adequate PSUs.

Understanding the RX 9060 XT's Power Demands

Official Specifications Summary

Metric	Value	Notes
GPU Model	AMD Radeon RX 9060 XT	Desktop Graphics Card

The Critical Factor: Transient Power Spikes

Transient power spikes represent brief, intense increases in power draw that can overwhelm PSUs. These spikes can cause sudden system shutdowns even when average power consumption appears manageable.

Show All Budget Build Balanced Build Optimal Build

Build Type	CPU Pairing	PSU Recommendation	Rationale
Budget Build	Ryzen 5 7600, Intel i5 non-K	550W (High Quality)	Technically sufficient but requires premium PSU with excellent transient response. May need GPU undervolting.
Balanced Build	Ryzen 5 7600X, Intel i5-13600K	650W	Comfortable headroom for peak loads and transient spikes. Operates at optimal 50% efficiency point.
Optimal Build	Ryzen 7 7800X3D, Intel i7/i9	750W+	Maximum stability and future-proofing. Ideal for overclocking and component upgrades.

Conclusion: Making an Informed Decision

Key Takeaways

550W can work - but only with high-quality PSUs and efficient CPUs
Transient spikes matter - they can reach 280W+ and cause shutdowns
650W is safer - provides optimal efficiency and stability headroom
Quality over quantity - PSU brand and transient response are crucial
Consider undervolting - can reduce power draw by 20% without performance loss

Final Recommendation

While a high-quality 550W PSU can technically power the RX 9060 XT, a 650W unit offers better long-term stability, efficiency, and upgrade potential. For budget-conscious builders willing to accept some risk and potential fine-tuning, a premium 550W PSU from brands like Seasonic or Corsair can work with power-efficient CPUs.
