Best SFX PSUs to Buy in 2018 – Computer Power Supply

If you are building a decent gaming PC, the PSU or Power Supply plays an important role in determining reliability. In this article, I am going to list the best SFX Power Supply which you can easily by in 2018. An SFX PSU is a small form factor power supply that is smaller than a regular ATX PSU.

As I mentioned above that Power Supply is the important component of your Computer System. Many users choose a power supply based on total wattage alone, assuming that higher is always better. But, there are many factors which you have to look after before buying a new ATX PSUs.

How to Choose the Best Power Supply

1. 1. The First thing you have to look at before buying a new Power Supply is that the Manufacturer. Always go with the reputed brand. Avoid cheap, generic power supplies.
   2. If you are going for the SFX PSUs, then you must have known that these are very small as compared to normal ATX. So, size is also an important parameter to consider.
   3. You should also check the PSU’s connectors to confirm the unit is compatible with your particular system. The term 20+4 pin refers to a connector that can function as either a 20-pin connector or a 24-pin connector.
   4. Check the number of +12V rails in the Power Supply. A “single-rail” power supply has a single, high-power +12V rail for feeding power to hungry system components. A “multi-rail” unit divides its output between two or more +12V rails.

These are some of the parameters which you have to look before buying a new SFX PSU for your PC.
