A 600W power supply unit (PSU) is generally sufficient for an RTX 4060, as NVIDIA recommends a minimum 550W PSU. However, total system power consumption, component efficiency, and transient power spikes must be considered. High-quality 600W PSUs with 80+ Bronze certification or higher can reliably support the RTX 4060 in most mid-range gaming setups.

What Are the Official Power Requirements for the RTX 4060?
NVIDIA officially recommends a 550W PSU for the RTX 4060. This accounts for typical gaming workloads and system configurations, including a mid-tier CPU, 16GB RAM, and standard peripherals. The GPU itself draws up to 115W under load, but total system consumption can exceed 300W depending on additional components.
How Does Total System Power Consumption Affect PSU Requirements?
The RTX 4060’s 115W TDP doesn’t reflect total system draw. A mid-range CPU (e.g., Ryzen 5 7600X) adds 105W, while RAM, storage, and cooling contribute 50–80W. Gaming setups often peak near 400W, leaving a 200W buffer on a 600W PSU. Insufficient overhead risks instability during power spikes or future upgrades.
Why Does PSU Efficiency Matter for the RTX 4060?
PSU efficiency (80+ ratings) ensures stable power delivery and reduces heat output. A 600W 80+ Gold unit provides ~540W of reliable power, whereas non-certified PSUs may struggle under sustained loads. High efficiency also lowers electricity costs and extends component lifespan by minimizing voltage fluctuations.
Efficiency ratings directly correlate with how much power is wasted as heat during conversion from AC to DC. For example, an 80+ Bronze PSU operates at 82% efficiency under 50% load, while an 80+ Gold unit achieves 87%. Over time, this difference can save 15–20 kWh annually for average users. Higher efficiency also reduces thermal stress on other components, which is critical for systems with limited airflow. Gamers running extended sessions should prioritize Gold or Platinum ratings to maintain consistent performance.
| 80+ Rating | Efficiency at 50% Load | Annual Power Savings* |
|---|---|---|
| Bronze | 82% | 12 kWh |
| Gold | 87% | 18 kWh |
| Platinum | 90% | 24 kWh |

Can a 600W PSU Handle RTX 4060 Transient Power Spikes?
Modern GPUs like the RTX 4060 experience brief power spikes up to 1.5x their TDP (≈170W). Quality 600W PSUs with robust 12V rails (e.g., 50A) can absorb these spikes without tripping protections. Cheap units may fail or cause crashes due to insufficient transient response.
How Do PSU Connectors Impact Compatibility with the RTX 4060?
The RTX 4060 uses a single 8-pin or 12VHPWR connector. Most 600W PSUs include at least one PCIe 8-pin cable, but newer units with 12VHPWR ensure future compatibility. Adapters can bridge gaps but may introduce resistance, slightly reducing efficiency.
The 12VHPWR connector supports up to 600W of power delivery through a single 16-pin interface, simplifying cable management compared to dual 8-pin setups. However, older PSUs may require a 2×8-pin to 12VHPWR adapter. Users should verify their PSU’s +12V rail capacity—at least 30A is recommended for stable operation. Below is a comparison of common connector types:
| Connector Type | Pins | Max Power | Compatibility |
|---|---|---|---|
| 8-pin PCIe | 8 | 150W | Universal |
| 12VHPWR | 16 | 600W | ATX 3.0 PSUs |
Are There Real-World Examples of 600W PSUs Running RTX 4060 Systems?
Testing shows systems with RTX 4060, Ryzen 5 7600X, and 32GB RAM draw 370–420W under gaming loads. A Corsair CX600 (600W, 80+ Bronze) maintained stable voltages, while a Thermaltake Smart 600W triggered occasional shutdowns during spikes. Component quality directly impacts reliability.
“A 600W PSU is adequate for the RTX 4060 in most cases, but never cheap out. Transient responses and rail stability matter more than headline wattage. I’d pair it with at least a Tier B unit from the PSU Cultist List.”

FAQs
- Q: Can a 600W PSU run an RTX 4060 and Ryzen 7 5800X?
- A: Yes, but ensure the PSU has a 45A+ 12V rail. Total draw may reach 450W under load.
- Q: Does the RTX 4060 require a new 12VHPWR connector?
- A: No—it supports traditional 8-pin connectors, but 12VHPWR improves efficiency in compatible PSUs.
- Q: Is 600W enough for RTX 4060 SLI?
- A: No. Dual RTX 4060s need 800W+ due to combined power spikes and increased heat.
