This in-depth blog post explores everything you need to know about the Dell SFF power supplies, with a particular focus on the Dell 3060, 5060, 3470, and 3080 SFF PSU models. We’ll review technical specs, discuss compatibility, provide upgrade recommendations, and compare against third-party alternatives. By the end of this article, you’ll have a complete understanding of the Dell SFF PSU landscape, helping you make informed decisions whether you’re replacing or upgrading.
🔍 Overview: What Is an SFF Power Supply?
Small Form Factor (SFF) desktops are compact PCs designed for space-saving deployments without sacrificing essential performance. These systems require SFF-specific PSUs that are smaller in size (typically around 200W–300W) and built to match the dimensions and airflow of the SFF chassis.
The Dell OptiPlex 3060, 5060, 3470, and 3080 models are among Dell’s most popular business desktop lines and share similar SFF PSU form factors with key differences in wattage, connector types, and efficiency ratings.
⚙ Dell SFF PSU Models: Core Specifications
Let’s start with a breakdown of the specifications for each of the target models:
| Model | PSU Wattage | Form Factor | Efficiency Rating | Main Power Connector | GPU Compatibility | Upgrade Options |
|---|---|---|---|---|---|---|
| Dell 3060 SFF | 200W | SFF | 80 PLUS Bronze | 8-pin proprietary | Low-profile GPUs | Limited |
| Dell 5060 SFF | 200W | SFF | 80 PLUS Bronze | 8-pin proprietary | Low-profile GPUs | Limited |

Warning: Always verify the pin layout and voltage rails before using a third-party PSU in a Dell system.
🧰 How to Upgrade Safely
If you want to upgrade your PSU in a Dell SFF PC, follow these steps:
- Check compatibility with your motherboard’s power connectors.
- Use a Dell 8-pin to 24-pin adapter if switching to a standard PSU.
- Measure the space available in the chassis.
- Ensure your replacement PSU provides enough wattage (esp. for GPU).
- If installing a GPU, check the combined power draw vs PSU capacity.
