INTRODUCTION

   Small form factor PCs may have been quite popular when i first started doing reviews (primarily as HTPCs) but they were never really for me, mainly due to their limited interior case space. Still, there's no denying that there's an increasing segment of the market that favours them because of their compact size and this is also why we've lately seen the introduction of more hardware components compatible with micro-ATX and mini-ITX cases. SFX power supply units in particular have significantly risen in popularity since 2020 and today with me i have one of the highest acclaimed models currently available in the market, the Focus SPX-750 White by Seasonic.

   Sea Sonic Electronics Co., Ltd was founded more than 40 years ago by engineers. Since its early beginnings the company has rigorously maintained its focus on the research, development and production of technologically advanced, high quality products. In 1981 Sea Sonic expanded into the production of PC power supplies to become one of the first manufacturers in this market. Soon after, the manufacturing of high quality and performance PC power supplies became the core identity of Sea Sonic.

   The Focus SPX line of SFX power supply units is available in black and white colors and includes 650/750W output models (just 750W for the white version) all of which are fully modular and feature the 80 Plus Platinum certification (92% electrical efficiency). Other features include Seasonic’ s three-phased thermal control for optimal balance between silence and cooling (three modes, fanless, Silent and Cooling), APFC (active power function correction), DC to DC design, 100% Japanese aluminum capacitors, gold plated connectors, 92mm fluid dynamic bearing fan and several industrial grade electrical protections including OPP (over-power), OVP (over-voltage), UVP (under-voltage), SCP (short-circuit), OCP (over-current) and OTP (over-temperature). The Focus SPX-750 750W model which i have here with me can deliver up to 862W (peak) and sports a strong 62A single +12V rail which can deliver 99% of the units’ total power output - 744W (minor rails have an output of up to 118.6W). Finally, Seasonic covers their entire Focus SPX line of power supply units with a really generous 10-year limited warranty.
