When it comes to building a computer, one of the most important components is the power supply. It provides the necessary power to all the components, including the CPU, motherboard, RAM, and storage devices. With the increasing popularity of micro ATX boards, many users are wondering if they can use an ATX power supply with their micro ATX board. In this article, we will explore the possibilities and limitations of using an ATX power supply with a micro ATX board.
Understanding ATX and Micro ATX Power Supplies
Before we dive into the compatibility of ATX power supplies with micro ATX boards, let’s first understand the difference between ATX and micro ATX power supplies.
ATX power supplies are designed to meet the power requirements of standard ATX motherboards. They typically have a larger form factor and higher power output, ranging from 300W to 1000W or more. ATX power supplies usually have a 24-pin main power connector, an 8-pin CPU power connector, and several peripheral power connectors.
Micro ATX power supplies, on the other hand, are designed for micro ATX motherboards. They have a smaller form factor and lower power output, typically ranging from 200W to 500W. Micro ATX power supplies usually have a 24-pin main power connector, a 4-pin CPU power connector, and fewer peripheral power connectors.
Key Differences Between ATX and Micro ATX Power Supplies
The key differences between ATX and micro ATX power supplies are:
- Form factor: ATX power supplies are larger than micro ATX power supplies.
- Power output: ATX power supplies have a higher power output than micro ATX power supplies.

- Form factor: Choose a power supply that fits in your case.
| Power Supply | Power Output | Efficiency | Connectors | Form Factor |
|---|---|---|---|---|
| ATX Power Supply | 300W-1000W | 80 PLUS Gold or higher | 24-pin main power connector, 8-pin CPU power connector, peripheral power connectors | ATX |
| Micro ATX Power Supply | 200W-500W | 80 PLUS Bronze or higher | 24-pin main power connector, 4-pin CPU power connector, fewer peripheral power connectors | Micro ATX |
Conclusion
In conclusion, you can use an ATX power supply with a micro ATX board, but it’s essential to consider the physical compatibility, power output, and connectors. While using an ATX power supply can provide several benefits, such as future-proofing and increased power output, it’s crucial to weigh the drawbacks, including size, cost, and efficiency. When choosing a power supply for your micro ATX board, ensure it meets the power requirements, has high efficiency, and fits in your case.
By understanding the differences between ATX and micro ATX power supplies and considering the factors mentioned above, you can make an informed decision when choosing a power supply for your micro ATX board.
What is the main difference between a Micro ATX and an ATX power supply?
The main difference between a Micro ATX and an ATX power supply lies in their physical size and the type of motherboard they support. A Micro ATX power supply is designed to work with Micro ATX motherboards, which are smaller than standard ATX motherboards. On the other hand, an ATX power supply is designed to work with standard ATX motherboards.
