SFX PSU Buying Guide
SFX power supplies are becoming increasingly popular among PC enthusiasts who want to build compact and portable systems. SFX PSUs are smaller in size than standard ATX power supplies, making them perfect for mini-ITX and micro-ATX builds. In this guide, we’ll take a closer look at SFX PSUs and how to choose the right one for your needs.
What is an SFX PSU?
SFX stands for Small Form Factor, which refers to the size of the power supply. SFX PSUs are smaller than ATX power supplies, allowing them to fit in compact cases. The standard size for an SFX PSU is 100mm wide, 125mm long, and 63.5mm tall. In comparison, ATX power supplies are typically 150mm wide, 86mm tall, and 140mm long.
SFX power supplies are not limited to mini-ITX and micro-ATX builds. They can also be used in standard ATX cases with an SFX to ATX adapter bracket.
Why Choose an SFX PSU?
There are several reasons why you might choose an SFX PSU over a standard ATX power supply:
- Size: SFX PSUs are smaller in size, making them ideal for compact builds.
- Portability: If you frequently transport your PC or plan on building a portable PC, an SFX PSU can help reduce the overall weight and size of your system.
- Ease of Installation: SFX PSUs are easier to install in small cases due to their size.
Power Output
When choosing an SFX PSU, the power output is a crucial factor to consider. The power output of an SFX PSU is typically lower than that of an ATX PSU due to its smaller size. The wattage of an SFX PSU can range from 200W to 800W, with most models falling in the 450W to 650W range.
Before choosing an SFX PSU, it’s important to determine the power requirements of your system. The power consumption of your system will depend on the components you use, such as the CPU, GPU, and other peripherals.
Most manufacturers provide a power supply calculator on their website that can help you determine the power requirements of your system. It’s important to choose an SFX PSU that can handle the power requirements of your system without being overloaded.
Modular or Non-Modular?
SFX PSUs can be either modular or non-modular. Modular power supplies feature detachable cables, allowing you to connect only the cables you need for your system. Non-modular power supplies come with all the cables attached, which can lead to clutter and make cable management more challenging.
Modular SFX PSUs are generally preferred by PC builders due to their ability to reduce clutter and simplify cable management. However, they may be more expensive than non-modular power supplies.
Efficiency and Certification
The efficiency of an SFX PSU is an important factor to consider. A more efficient PSU will consume less power and generate less heat, which can help reduce your electricity bills and the load on your cooling system.
PSUs are certified by organizations such as 80 Plus and Cybenetics, which test and certify the efficiency of PSUs based on their efficiency at different loads. The most common certifications are 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, 80 Plus Platinum, and 80 Plus Titanium.
The higher the certification level, the more efficient the PSU is at converting AC power to DC power. While higher-certified power supplies are generally more expensive, they can pay for themselves over time through reduced energy bills.
Fan Size and Noise Level
The size of the fan in an SFX PSU can affect the noise level of your system. Smaller fans tend to be noisier than larger fans, as they need to spin faster to provide the same amount of cooling. When choosing an SFX PSU, look for models with larger fans or low-noise fans to minimize noise.
Brand and Warranty
When choosing an SFX PSU, it’s important to choose a reliable brand with a good reputation for quality and customer service. Some of the most popular brands for SFX PSUs include Corsair, Silverstone, EVGA, and Seasonic.
Most SFX PSUs come with a warranty ranging from two to five years. A longer warranty period can provide peace of mind and protection in case of a failure.
Conclusion
Choosing the right SFX PSU for your build can be challenging, but it’s important to consider factors such as power output, efficiency, certification, fan size, and warranty. By carefully considering these factors and choosing a reliable brand, you can ensure that your SFX PSU will provide reliable and efficient power to your system for years to come.
