In the minds of customers, Seasonic has long been associated with products for enthusiasts, so the PRIME line presented in 2018 was created with the sole purpose of emphasizing the status of the brand. For this series, only elite power supplies with "titanium" and "platinum" quality certificates, the famous silent cooling system, modular cables and useful little things like a case for removable cables or an assembly screwdriver are selected. Well, the circuitry is such that it could be used in an Iron Man suit. Is it a joke if not the top-end Seasonic PRIME GX in overload mode provides 22% of the power reserve on the main line.


The model range of the PRIME series includes a whole scattering of elite power supplies with a serious power reserve and quality certificates of 80+ Platinum, 80+ Titanium and 80+ Gold. Most of the variants are represented by versions from 650 to 1000 watts, which are accompanied by a few and not quite format models for 450 and 1200 watts. All of them relate to the ATX form factor. Seasonic is confident in the quality of electronics and the reliability of cooling systems, so they give most PRIME models as much as 12 years of warranty, although in this market it is customary to limit 3 – 5 years of service.

In addition to the classic components, there are also unusual variations in this line, in which the cooling fans are replaced with radiators with passive cooling. Some units in this series can boast an 80PLUS Titanium quality certificate and the highest power output among all fanless power supplies that are sold in 2021.

All this makes the PRIME FANLESS models an perfect solution for any situation that requires absolute silence and phenomenal reliability from the equipment.
