What PSU is required for the RTX 4060? NVIDIA recommends a 550W power supply for the RTX 4060, though some models may work with 500W. The GPU draws ~130W under load, but system-wide power needs, efficiency losses, and transient spikes necessitate a higher-wattage PSU. Always prioritize units with 80 Plus Bronze certification or better for stability.

How Much Power Does the RTX 4060 Consume?
The RTX 4060 has a TDP of 130W, peaking at 150W during heavy workloads. Actual consumption depends on cooling, overclocking, and game optimization. Pairing it with a 550W PSU ensures headroom for CPUs (e.g., Ryzen 5 7600X or Intel i5-13400F), storage, and peripherals. Undervolting can reduce draw by 10-15% without performance loss.
Which Power Connectors Does the RTX 4060 Use?
Most RTX 4060 models use a single 8-pin PCIe connector, though Founders Edition cards may draw power directly from the PCIe slot. Avoid adapters; use PSUs with native 8-pin cables. Modular PSUs simplify cable management, while daisy-chained connectors risk voltage drops in multi-GPU setups (not applicable here).
Third-party models like the ASUS Dual RTX 4060 and Gigabyte Windforce OC utilize the traditional 8-pin design, while compact ITX variants often rely solely on PCIe slot power. Below is a comparison of popular models and their connector requirements:
| Model | Power Connector | Minimum PSU |
|---|---|---|
| NVIDIA Founders Edition | PCIe Slot Only | 500W |
| MSI Ventus 2X | 1x 8-pin | 550W |
| ZOTAC Twin Edge | 1x 8-pin | 550W |
Does PSU Efficiency Affect RTX 4060 Performance?
Higher efficiency (80 Plus Gold/Platinum) reduces heat and energy waste, improving PSU longevity. Lower-quality units may struggle with transient spikes, causing crashes. For example, a 500W Bronze PSU delivers ~450W sustainably, whereas a Gold unit provides ~475W. Efficiency matters most in high-temperature environments or 24/7 workloads.
Efficiency ratings directly impact power delivery consistency. A Platinum-rated PSU maintains >90% efficiency even at 50% load, reducing thermal stress on components. This becomes critical when pairing the RTX 4060 with power-hungry CPUs like the Ryzen 9 7900X. Consider the following efficiency benchmarks at 50% load:
| PSU Rating | Efficiency at 50% Load | Typical Heat Output |
|---|---|---|
| 80 Plus Bronze | 85% | 45°C |
| 80 Plus Gold | 90% | 38°C |
| 80 Plus Platinum | 92% | 35°C |
Can a 500W PSU Run an RTX 4060 Safely?
Yes, but only with low-power CPUs (e.g., Ryzen 5 5600G) and no overclocking. Stress testing shows 500W units hitting 90% load, risking instability during spikes. Tier-B PSUs (Corsair CX550M, EVGA 500 BQ) are the minimum. Avoid no-name brands—their 500W units often deliver <400W reliably.
What Happens If You Use an Underpowered PSU?
Insufficient wattage causes shutdowns, blue screens, or hardware damage. For example, a 450W PSU with an RTX 4060 and i5-12400F may trip overcurrent protection during gaming. Symptoms include flickering screens or GPU throttling. Always use PSU calculators (e.g., OuterVision) and add 20% headroom for aging components.
How to Future-Proof Your PSU for GPU Upgrades?
Choose 650-750W units for headroom. Future GPUs (e.g., RTX 5070) may require 200W+ and new connectors. Modular PSUs with PCIe 5.0 12VHPWR support (MSI MPG A750G) ensure compatibility. Prioritize multi-rail designs for safer power distribution across components.
Expert Views
“The RTX 4060’s efficiency masks its sensitivity to poor power delivery,” says Alex Rivera, senior engineer at Cooler Master. “A low-end PSU might handle daily tasks but fail during transient spikes unique to Ada Lovelace GPUs. Invest in units with Japanese capacitors and a 7-year warranty—it’s cheaper than replacing a fried motherboard.”
Conclusion
The RTX 4060 demands a 550W PSU minimum, with adjustments for CPU and peripherals. Prioritize reliable brands and future-proof with higher-wattage, efficient units. Balancing cost and performance ensures stability and longevity for gaming or content creation setups.
FAQ
- Can I use a 450W PSU with the RTX 4060?
- Not recommended. Even with low-power components, 450W leaves no headroom for spikes, risking instability.
- Does the RTX 4060 need a new PSU if upgrading from a GTX 1060?
- Yes. The GTX 1060’s 400W requirement is lower than the RTX 4060’s 550W. Older PSUs may lack connectors and efficiency.
- Are PCIe adapters safe for the RTX 4060?
- Avoid them. Adapters increase resistance and fire risk. Use PSUs with native 8-pin or 12VHPWR cables.
