Seasonic Prime 750W Titanium Power Supply Review

Rating: 9.5.

It has been talked about and teased for many months, but today we finally get to present our analysis of the new PRIME 750 watt power supply, a pivotal supply in a very important new range for market leading manufacturer Seasonic.


Seasonic are releasing Titanium rated 650W and 750W supplies now, with a more powerful 850W unit due for release in August … followed by the flagship 1000W unit with availability set for November. At the end of the year the plans are for Seasonic to release an additional 600W fanless unit – specifically targeting the enthusiast audience who love the ‘sound of silence’. Based on the Seasonic track record in our labs we have high hopes for this upcoming fan less 600 watt power supply.

While we are focusing on the new Titanium 750 watt unit today, Seasonic also have plans to release Platinum and Gold PRIME supplies later this year at the end of Q3 and in Q4. Over the coming months we hope to get our hands on a wide selection of units to supplement this PRIME launch review today.

The Seasonic PRIME Titanium range is fully modular, and they incorporate low noise 135mm Fluid Dynamic Bearing fan.

  • Ultra-High Efficiency, 80 PLUS® Titanium Certified.

    Was this tested at 230V or 110V?

    This Review says 10 year Warranty but Seasonic says 12: http://seasonic.com/prime/ – it’s only 2 years, but so are some Warrantys.

    You might get 3 or more builds out of it, and it will still be under Warranty.

    It’s not like it’s going to fail in 12y1m and you may never need more than the 1000W model; with Chips using less and less power, and few upgrading their Homes’s wiring to higher amperage sockets.
