PSU Requirement Breakdown
NVIDIA GeForce RTX 4060
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
AMD Radeon RX 9070 requires less PSU headroom per dollar spent. It needs 600W recommended at $449, versus 450W at $299 for the NVIDIA GeForce RTX 4060.
Frequently Asked Questions
Which PSU do I need for NVIDIA GeForce RTX 4060?
NVIDIA GeForce RTX 4060 has a 115W TBP but can spike to 226W 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 or AMD Radeon RX 9070 need ATX 3.1?
NVIDIA GeForce RTX 4060 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.
