Power supply Seasonic PRIME TX-1300TR2, 1300W, 80 Plus Titanium PSU, SSR-1300TR2, ATX 3.1, PCIe Gen 5.1 - 1TX13TART3A10X

Seasonic PRIME TX-1300TR2 is a high-end 1300W ATX power supply, aimed at serious gaming and workstation configurations with powerful GPUs and plenty of peripherals. With 80+ Titanium certification and up to 94% efficiency under load, this PSU is designed for stability and low losses, even under long and heavy load. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 prepares you for current and future graphics cards. Add a fully modular design and a 135mm FDB fan, and you get a serious, quiet, and well-sized power supply for a top build.

What you get

With real 1300W and a wide input 100–240 VAC, this power supply easily handles high-end CPUs plus one or two power-hungry GPUs without pushing it to its limits. The two PCI-E Gen5 12VHPWR connectors provide direct compatibility with modern graphics cards without the need for adapters, while the eight PCI-Express 6+2 pin cover any combinations of GPUs and additional cards. With a total of 16 SATA and additional SATA 3.3 V and Molex connectors, you can attach a whole array of SSDs, HDDs, and accessories in a large chassis or NAS-like build. Active PFC and protections OPP, OVP, UVP, OCP, OTP, SCP protect your configuration from network issues or overload. The FDB bearing fan sized 135 mm is designed for low noise and long life, and with MTBF 100,000 hours, it’s clear that this PSU is meant for long-term use.

• 1300W nominal power allows you to power a high-end system with a powerful GPU/CPU without the risk of shortage during peak loads.
• 80+ Titanium certification and up to 94% efficiency mean less loss in heat, lower power consumption, and less load on the case cooling.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 compatibility ensure readiness for the latest graphics cards and standards without the need for adapters and compromises.
• 2x PCI-E Gen5 12VHPWR and 8x PCI-Express 6+2 pin provide flexibility for a multi-GPU setup or a combination of a powerful GPU and additional cards.
• 16x SATA, 2x SATA 3.3 V and 3x Molex provide enough power for many drives, controllers, fan hubs, and other accessories.
• 135mm FDB fan combines quiet operation with long life, suitable for machines that run for hours under load.
• Full set of protections (OPP, OVP, UVP, OCP, OTP, SCP) keeps your components safe from overload, overheating, short circuits, and power deviations.
• Size 210 x 150 x 86 mm in ATX format is typical for a powerful PSU and is good to keep in mind for more compact cases.
• 99 months warranty shows a long-term focus and trust in the reliability of the power supply.

Who it is suitable for

This PSU is a logical choice for high-end gaming configurations, workstations for rendering, 3D and video, as well as for enthusiasts with lots of storage and additional cards. If you are building a budget or mid-range build with a more economical GPU, 1300W and Titanium class will likely be excessive for you – a more modest power supply will do the same job. But if you plan long-term, an overkill PSU like this provides peace of mind and headroom for future upgrades.

The combination of 1300W power, 80+ Titanium efficiency, modern ATX 3.1 / PCIe Gen 5.1 standards, and a serious set of connectors make the Seasonic PRIME TX-1300TR2 a very stable foundation for a heavy, long-term build. This is the type of power supply that you install and forget about for a long time.
