Seasonic Prime Ultra Titanium 1000W Power Supply Review

The Seasonic Prime Ultra Titanium 1000W is another stellar unit from the market leader. First impressions are positive – the box artwork is eye catching, the bundle is comprehensive and the build quality is at the highest level.

Load regulation is class leading and as we would expect with a Seasonic design they have massively over specified the capacitors. We managed to get just over 300 watts more from the supply before it safely shut down.

 

Ripple suppression and efficiency are both first rate, and technically the unit delivers the goods without any notable issues I could mention.

The modular cabling is great, although I have noticed some other manufacturers in recent months are making their CPU cable length longer to suit bigger physical builds. Something for Seasonic to look into perhaps in future revisions.

It is welcome to see Seasonic including some individual PCIe cables with this unit. This will be very welcomed by a specific enthusiast audience.

Seasonic offer a 12 year, market leading warranty with this unit, so you have peace of mind for a very long time indeed.

Right now we have no UK confirmed pricing. I know OCUK are starting to filter in units as we speak with the Prime Ultra Titanium 650W available at £179.99 inc vat HERE. No sign of the 1000W or 850W models, but we will update this page when possible.

Pros:

  • great build quality.
  • noise suppression is top drawer.
  • 12 year warranty.
  • massively over specified for 1000 watts.
  • 105c Japanese capacitors.
  • quiet.
  • plenty of accessories included.

Cons:

  • A longer CPU cable would help in really big system builds.

KitGuru says: The Seasonic Prime Ultra Titanium is one of the finest power supplies on the market. If you have the funds and need something this powerful, it should definitely be making your final shortlist.
