Seasonic Prime TX-1300 (1300W, 80+ Titanium, ATX 3.1)
A pro-tier 1300W flagship with 80 Plus Titanium efficiency, full modularity, ATX 3.1, and 12VHPWR, built for high-end multi-GPU or RTX 5090 systems and backed by a 12-year warranty. The Titanium rating and headroom are its selling points for power-hungry enthusiast rigs. It's plainly overspecced for typical single-GPU builds, where 1300W of Titanium is more than needed — a narrow, top-end fit.

Verdict
Best for
- high-end multi-GPU or RTX 5090 builds
- Titanium-efficiency enthusiasts
- 12-year warranty halo builds
Who should skip this
- Single mid-range GPU rigs — 1300W is vastly more capacity than they'll ever draw, and Titanium efficiency goes unrewarded at low load
- Value builders — the Titanium tier and 12-year warranty command a steep premium over an ample Gold 1000W
- Compact cases — a 1300W ATX unit is physically long and can crowd cable routing in smaller chassis
