Power Supply Seasonic Prime TX-1300 ATX3.1 SSR-1300TR2 80 Plus Titanium 1300W

Seasonic Prime TX-1300 1300W ATX 3.1 80+ Titanium Power Supply

The Seasonic PRIME TX ATX 3.1 series is built on every strength of the PRIME TX platform, with added compliance for the ATX 3.1 and PCIe 5.1 standards. This 1300W model combines the market's highest efficiency tier with quality components, making it an especially good match for the latest power-hungry graphics cards and processors.

Power & efficiency

The unit delivers 1300W and earns 80+ Titanium certification, the highest efficiency level available within this standard, with 94% efficiency at 50% system load. Such high efficiency translates into less wasted electricity, less heat and noticeable savings over time.

Cables & connectors

The model is fitted with native 12V-2×6 connectors in the 16-pin PCIe Gen 5 standard, engineered for new PC components that require ATX 3.1 and PCIe 5.1. That lets you connect a next-generation graphics card directly without adapters for a safe, stable link.

Reliability & cooling

A Digital Fan Control system manages cooling intelligently and precisely according to the actual load. Japanese electrolytic capacitors rated to 105°C ensure stable power delivery and long-term endurance even under demanding working conditions.
