Seasonic PRIME TX ATX 3.1 Spec and Price in Brazil
Seasonic's flagship: the PRIME TX ATX 3.1 is 80 PLUS Titanium certified at 94% efficiency under half load, and Seasonic backs it for twelve years, the same term the rest of the PRIME range carries. Both current units, 1300W and 1600W, carry native 12V-2x6 connectors for PCIe 5.1 graphics cards and a 135mm fluid-dynamic-bearing fan under digital hybrid control that stays stopped at low load. At 210mm deep it is a large unit, so check clearance before buying it for anything but a full tower.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers describe the internal design as very high quality, built from proven components and finished to flagship standards.
- The 135mm fan stays stopped for long stretches even at several hundred watts of load, so it runs quietly in ordinary use.
Commonly criticised
- At 210mm deep and around 3kg it is a large, heavy unit that will not suit every case.
- It is positioned at a premium price for its capacity.
