20 Best Sfx L Power Supply (2023 Updated)

A switched-mode power supply (SMPS) is an electronic power converter that converts power using switching devices that are turned on and off at high frequencies, and storing the energy in inductors or capacitors rather than in batteries.

This type of power supply is much more efficient than a linear power supply because it doesn’t waste power in the form of heat.

Conclusion

The SFX L power supply is a great choice for a gaming PC. It has plenty of power to handle all of your gaming needs, and it is also very quiet. The only downside is that it is a bit more expensive than some of the other power supplies on the market.
