Seasonic X-Series 850W Power Supply Review

Rating: 9.0.

Recently we analysed the Seasonic X-Series 1250W power supply aimed at the ultra high end enthusiast market. Today we supplement that review with a look at the more cost efficient X-Series 850W model, priced around the £150 mark. This is a fully modular design which has achieved 80 Plus Gold Certification.

Seasonic are using high grade 105c Japanese capacitors with a focus on maintaining low noise levels regardless of the load situation.

In a similar fashion to the 1250W version, the X-Series 850W adopts a “Hybrid Silent Fan Control” design, which offers three distinct operation modes, fanless mode, silent mode, and cooling mode. The X automatically adjusts fan mode and speed according to the ambient temperature level. This brand new design not only optimizes heat dissipation, but also prolongs lifespan of the system by reducing unnecessary fan rotation.
