Seasonic PRIME TX-1000 1000W Titanium PSU

The Seasonic PRIME TX-1000 is a 1000 W ATX12V power supply certified to 80 PLUS Titanium with an average efficiency of 93.28 %. It uses a fully modular design and a single +12 V rail rated at 83 A. A 135 mm fluid dynamic bearing fan with hybrid control offers a selectable fanless mode. Premium Japanese capacitors and micro tolerance load regulation under 0.5 % support stable delivery for high-performance systems.

Suited for high-end builds needing 1000 W Titanium

This unit suits builders who want full modular cabling, a single 83 A rail and Cybenetics A- noise certification. It provides eight 6+2-pin PCIe connectors and fourteen SATA power connectors for multi-GPU or storage-heavy configurations. Buyers who need a lower maximum power rating or a non-modular design should look at something else. The 170 mm depth also requires a case that can accommodate that length.

Check case clearance and cable requirements before

Verify that your chassis allows a power supply depth of 170 mm and that the 24-pin ATX and EPS connectors match your motherboard. Ensure the eight 6+2-pin PCIe cables meet your graphics card needs and that the fourteen SATA connectors cover your drives. Confirm the 100-240 V input range matches your mains supply. The unit includes OPP, OVP, UVP, OCP, OTP and SCP protections.

Questions about this item

Will the 170 mm length fit in a standard mid-tower case?

The unit is 170 mm long, which matches the typical maximum for most mid-tower cases. Check your case specification for the exact PSU clearance before ordering.

Can I run two high-end graphics cards with the eight 6+2-pin PCIe connectors?

Yes, the eight 6+2-pin connectors support up to four dual-connector cards or two cards that each need three connectors, all on the single +12 V rail rated at 83 A.

Does the fan stay off at low load and how do I choose the mode?

A rear switch selects S3FC for fanless operation at low load or S2FC for constant fan spin; the 135 mm fluid-dynamic-bearing fan runs only when needed in S3FC mode.
