PSU Requirement Breakdown
NVIDIA GeForce RTX 4060 Ti
AMD Radeon RX 9070
⚠ AMD Radeon RX 9070 requires 2 separate 8-pin PCIe power cables. DO NOT daisy-chain — each cable must run directly from the PSU to the GPU.
Power Efficiency Verdict
NVIDIA GeForce RTX 4060 Ti requires less PSU headroom per dollar spent. It needs 450W recommended at $399, versus 600W at $449 for the AMD Radeon RX 9070.
Frequently Asked Questions
Which PSU do I need for NVIDIA GeForce RTX 4060 Ti?
NVIDIA GeForce RTX 4060 Ti has a 160W TBP but can spike to 251W during transient loads. We recommend a minimum 450W ATX 3.1 PSU for safe operation with headroom.
Which PSU do I need for AMD Radeon RX 9070?
AMD Radeon RX 9070 has a 250W TBP and transient peak up to 426W. We recommend a minimum 600W ATX 3.1 PSU for stable operation.
Does NVIDIA GeForce RTX 4060 Ti or AMD Radeon RX 9070 need ATX 3.1?
NVIDIA GeForce RTX 4060 Ti uses a standard 8pin-x1 connector and does not strictly require ATX 3.1, though an ATX 3.x PSU is still recommended for transient headroom. AMD Radeon RX 9070 uses 8pin-x2 and does not require ATX 3.1.
