PSU Overview
The PSU in black and chrome and looks stunning! While holding it, one can feel the quality!
The top of the PSU resembles a honeycomb to allow sufficient airflow when the 135MM fluid dynamic bearing fan is engaged to cool the unit.
The front contains all the ports as well as the Seasonic logo and the Prime branding.
The side also contains the Prime branding and a small slit for additional airflow
The back contains the Seasonic logo with the input voltage of 100-240VAC, power cable port, power button, and hybrid fan control.
Features
The Prime TX holds the highly coveted 80 Plus Titanium certification. This means that the Prime TX has a 94% efficiency rating at 50% load. Additionally, Seasonic employs the use of a 135mm fluid dynamic bearing fan which is not only extremely reliable but is also a lot quieter than traditional ball bearing fans.

The Prime TX also uses a cable-free connection design to connect the back panel to the PCB. Other power supplies in the market connect the back panel to the PCB with cables, while Seasonic uses a copper plate. Although this will likely to be unnoticeable to consumers, Seasonic states that it improves output power quality.
Lastly, the Prime TX employs the use of micro tolerance load regulation. This was developed by Seasonic to maintain the output voltage within an extremely tight range, achieving 0.5% load regulation. In addition to high quality parts, this feature makes the Prime TX a super stable power supply.
Performance
After using the Prime TX 1000 for nearly a month, I have not once heard the fan turn on. During light tasks such as internet browsing and office work, the fan has never turned on. With more intensive tasks such as gaming, video editing, and rendering the fan did turn on but was still virtually inaudible. Ultimately, the Prime TX 1000 is extremely quiet! You’d be hard pressed to hear any fan noise unless you have incredible hearing and are in an extremely quite room!
We featured the Prime TX 1000 in our upcoming 9900K/RTX 2080 Ti Phanteks Evolv X custom water cooled build.
Conclusion
As expected, the Seasonic Prime TX 1000 stands above the rest in all aspects! The Prime TX is not only a great looking power supply, but it also displays incredible performance and reliability. Seasonic truly stands above the rest when it comes to power supplies, this is why they are the industry leader and fearlessly provide a 12-year warranty with most of their units!
Seasonic once again has made it extremely difficult to find a negative when it comes to the Prime TX 1000. Perhaps its availability may be its only con. At the time of writing, the Prime TX 1000 is listed as sold out at all major retailers, likely due to supply constraints resulting from the COVID-19 pandemic.
Anyone looking for a long-lasting premium power supply, will find the Prime TX series to be an ideal solution. Overall, we highly recommend the Seasonic Prime TX 1000 and are proud to award it our Editor’s Choice award!
