Seasonic Prime 850W Titanium Power Supply Review

The Seasonic Prime 850W arrives in the same super shiny, highly reflective box that gets attention immediately.

The bundle is quite extensive. All the modular cables are stored in a cardboard box. Seasonic supply a user manual, a case badge, sticker, mounting screws as well as various plastic and branded felt cable ties.

The power supply is well protected between two thick slabs of foam. Seasonic have also wrapped it within a soft felt bag, shown above. They also supply a regional specific power cable. Full marks for packaging.

Seasonic have sleeved the main motherboard cable. All the other cables are ribbon style, flat – ideal for saving space and improving airflow when routing cables. They also include a regional specific power cable.

The cables are all very high grade, which is reassuring to see.

Both Prime 650 and 750 watt units are equipped with 4 PCI-E 6+2 power connectors – catering for the SLI and Crossfire audience. The 750 watt unit has 4 more SATA connectors, increasing from 6 on the 650W to 10 on the 750W. The 850W unit we are looking at today has 6x PCI-E 6+2 power connectors.
