Our 5 Best SFX Power Supply in 2022

Last Updated on August 19, 2022

The beauty of being a PC enthusiast is that you’re not constricted by any particular form factor, manufacturer, chipset, with the whole industry operating under de facto formats. The ATX form factor for power supplies, motherboards, and PC cases has stirred up competition between hardware manufacturers since the late 1990s and has made PC building much more accessible to your average consumer. Prior to the implementation of ATX, which was done by Intel in 1995, form factors were mainly proprietary to each company, riddling the PC market with incompatible parts, unfair pricing models, and a lot of confusion cast towards your average consumer.

Since then, the PC enthusiast market has come a long way. A lot of people compare it to lego blocks for adults. While the ATX format is probably one of the main reasons why PC building is so accessible in 2019, other formats still do exist, and that’s one of the beauties of building your own station. The SFX format is just a derivation from the ATX standard. For all intents and purposes, it functions in the same way and comes with all of the same connectors. You still get the same architecture, the same 24-pin ATX connector, the same outputs, the only difference being its size. SFX power supplies will fit in cases that are closer to PC modding than PC building.

Building in a custom case will likely require you to shop for an SFX power supply since smaller cases oftentimes don’t fit a full ATX power supply. For this reason, we’ve compiled a list of the top 5 best SFX power supplies that you can purchase in late 2019 and early 2020.

Our Verdict

Five PSUs, one choice. I’ll have to give the Seasonic Focus SGX-650 the cake, but only because of the care put by Seasonic into their packaging and the slightly better fan. Every PSU on the list was good. Grab one that’s within your budget and you’re going to be on your way to building a highly-compact, highly-performant system.
