The Seasonic Focus Plus Gold 750FX 750W PSU Review: SeaSonic Quality at Mainstream Prices

Conclusion

Exceptional quality, both internally and externally, is the signature feature of the Focus Plus Gold 750FX. Externally, the designers made sure that the PSU will be aesthetically appealing with a modern, yet not extravagant design. Internally, SeaSonic is using only top-quality components from known and reliable manufacturers – including using only Japanese capacitors – all while the design and assembly of the Focus Plus Gold 750FX are both exceptional. It is no coincidence that SeaSonic backs this unit up with a 10-year warranty, one of the longest offered for a PSU.

In terms of performance, the Focus Plus Gold 750FX is a great all-rounder, yet a master of none. Its greatest characteristic is the excellent acoustics performance, with the PSU operating inaudibly under low-to-regular load when the ambient temperatures are not too high. The power quality of the PSU may be unimpressive when compared to what top-tier PSUs may achieve, yet the figures are undoubtedly admirable for a mainstream product. It does run a little hot considering its power output and electrical efficiency, yet it's not hot enough to cause any issues.

As good as it may perform, there is a catch with the unit’s specifications that we should note – SeaSonic rates the PSU for operation up to 50°C, yet de-rates its power output for temperatures above 40°C. While the Focus Plus Gold 750FX was able to deliver the entirety of its rated power output while operating in our hot box, the platform is only rated for operation up to 40°C, and higher ambient temperatures will severely shorten the unit’s lifetime. Which for most builders shouldn't be a problem, but it could potentially be a concern if you intend to use the PSU in a consistently warm environment without air conditioning.

Overall, SeaSonic is obviously aiming the Focus Plus Gold series at the heart of the advanced PC market, with units that offer ample power output and good performance for the typical gaming/advanced workstation PC while preserving a relatively sensible price tag. The retail price of $110 is reasonable and on par with other high-quality products of comparable performance and quality, making the Focus Plus Gold 750FX an excellent deal for users that want a very reliable, good all-around PSU.
