Power supply Seasonic PRIME TX-1600 (1600W) 80 Plus Titanium PCIe Gen 5 PSU - SSR-1600TR

Seasonic PRIME TX-1600 is a high-end ATX power supply with 1600 W power and 80+ Titanium certification, aimed at the heaviest gaming and workstation configurations. With efficiency up to 94% and active PFC, it is designed to maintain stable voltages even under serious load. You get a fully modular design and a rich set of connectors, including PCI-E Gen5 12VHPWR, so you don't have to worry about powering modern GPUs. The black case and 135 mm FDB fan complete the picture with a quiet and thoughtful design.

What you get

With real 1600 W available and output power of DC 3.3/5/±12 V, this power supply is prepared for systems with multiple powerful GPUs, plenty of storage, and a serious CPU without hitting the limit. The two PCI-E Gen5 12VHPWR connectors give you direct compatibility with the new generation of graphics cards, while a total of 8 PCI-Express 6+2 pin cover older or professional GPU solutions. With a total of 16 SATA plus 2 SATA 3.3 V you can build a massive array of SSD/HDD, NAS, or storage server in one case. The three 4+4 Pin ATX/EPS provide enough power for high-end motherboards and HEDT platforms with reinforced VRM zones. The FDB fan with a diameter of 135 mm is designed for quieter operation and long life, which is important for 24/7 load.

• Power 1600 W – sufficient for multi-GPU builds, heavy workstations, and overclocked configurations without the risk of power shortage.
• 80+ Titanium certification with up to 94% efficiency – less loss as heat, lower load on the electrical network, and more stable operation under load.
• Two PCI-E Gen5 12VHPWR connectors – direct support for modern high-end GPUs, without the need for non-standard adapters.
• 8 x PCI-Express 6+2 pin and 3 x 4+4 Pin ATX/EPS – flexibility for systems with multiple graphics cards and powerful processors on enthusiast platforms.
• 16 x SATA, 2 x SATA 3.3 V and 3 x Molex – wide storage options, peripherals, and older hardware in the same build.
• Fully modular design – connect only the necessary cables, which simplifies cable management and improves airflow in the case.
• 135 mm FDB fan – smoother and quieter rotation with longer life, suitable for long gaming sessions or continuous operation.
• Wide input 100–240 VAC and ATX format – standard compatibility with most PC cases and electrical networks.

Who is it suitable for

This power supply is for enthusiasts and professionals building a high-end system – 4K/sport gaming, rendering, machine learning, or a powerful home/office server with many drives. If you are building a budget build or a mid-range configuration with a more moderate GPU, 1600 W is excessive and it’s better to opt for a lower class PSU.

The strongest point of the Seasonic PRIME TX-1600 is the combination of huge resource 1600 W, 80+ Titanium efficiency, and full readiness for ATX 3.0/PCIe Gen 5.0 hardware – a platform that allows you to think long-term.
