Description
Product Overview
The Seasonic Prime TX-1300 is a flagship 1300‑watt ATX 3.0 power supply engineered for extreme performance and efficiency. Certified 80 PLUS Titanium, it achieves up to 94% efficiency at typical loads, reducing waste heat and electricity costs. A single 135 mm fluid‑dynamic bearing fan provides quiet, consistent cooling, while the full‑modular cable system simplifies cable management and improves airflow inside the case. Built with premium components, including low‑ripple capacitors and micro‑tolerance load regulation (0.5 % variance), the unit guarantees stable voltage across all rails.
Usage
Designed for high‑end gaming PCs, professional workstations, and content‑creation rigs, the Prime TX-1300 powers multiple GPUs, high‑speed CPUs, and fast storage arrays without compromise. Its wide input voltage range (100‑240 V AC) makes it suitable for global markets, and the 6+2‑pin system bus connector supports the latest graphics cards. Whether assembling a custom water‑cooled rig or a compact ATX case, the fully modular design and PVC‑embossed cables enable clean builds and optimal airflow.

FAQ
Is the Prime TX-1300 compatible with the latest RTX 40 series GPUs?
Yes, the unit includes 6+2‑pin connectors and provides sufficient amperage to support multiple high‑end RTX 40 series graphics cards.
Can I use this PSU in a small form‑factor case?
The Prime TX-1300 follows the standard ATX dimensions (8.3 x 6 x 3.4 inches). While it fits most mid‑tower and full‑tower cases, very compact cases may require a smaller form factor.
What does the 12‑year warranty cover?
The warranty covers any defects in materials or workmanship for 12 years from the date of purchase, including full replacement or repair of the unit.
How does the micro‑tolerance load regulation benefit my system?
MTLR maintains voltage variation within ±0.5 % under varying loads, ensuring stable power delivery and protecting sensitive components from voltage spikes.
Do I need to install any additional software to monitor the PSU?
No additional software is required; the PSU provides standard voltage and power monitoring via the motherboard’s BIOS and compatible monitoring tools.
