1 (12V-2x6) 12年保証 Cybenetics チタン A 完全モジュラー RTX 5090 AMD RX 9000 Ready AI ワークステーション.

Overview

The Seasonic PRIME TX-1600 is a flagship power supply unit that delivers a massive 1600W of continuous power, compliant with the ATX 3.1 standard. It carries both 80 PLUS and Cybenetics Titanium certifications, achieving over 94% efficiency at 50% load. Built to handle next-generation graphics cards like the RTX 5090 and AMD RX 9000 series, this PSU is an excellent choice for high-end gaming rigs and AI workstations. Its standout feature is the dual native 12V-2x6 (PCIe 5.1) connectors, which can supply two high-power GPUs simultaneously without adapters. The fully modular cable design uses embossed PVC cables that are flexible and easy to route inside your chassis, allowing for clean, professional-looking builds. All internal capacitors are 100% Japanese brand, ensuring long-term reliability. With a 12-year warranty, this PSU is built to last through multiple system rebuilds. The 135mm fluid dynamic bearing (FDB) fan operates in hybrid mode, stopping entirely under low loads for near-silent operation.

Compatibility Guide

The Seasonic PRIME TX-1600 uses the standard ATX form factor, making it compatible with most mid-tower and full-tower cases. However, the unit's depth measures 210mm, which is longer than average. Always check your case's PSU clearance before purchasing — cases with a PSU shroud depth of at least 230mm are recommended for easy installation. It comes with two native 12V-2x6 (PCIe 5.1) connectors for RTX 40/50 series and upcoming AMD Radeon RX 9000 GPUs. For older graphics cards, multiple 6+2-pin PCIe connectors are included. The dual EPS12V 4+4-pin CPU connectors ensure compatibility with high-end motherboards like the ASUS ROG CROSSHAIR X870E HERO or MSI MEG Z890 ACE.

Product Info

Released in July 2023, the Seasonic PRIME TX-1600 (model PRIME TX-1600 ATX 3) sits firmly in the high-end, enthusiast tier of the PSU market. Its 1600W capacity and Titanium efficiency rating are overkill for most users, but for those running multi-GPU setups or sustained high-load workloads, it offers the headroom and stability needed. The 12-year warranty is among the longest in the industry, reflecting Seasonic's confidence in the build quality.

Best Use Cases

First, hardcore gamers building a single-GPU system with an RTX 5090 or RX 9000 series card, paired with a power-hungry CPU like the Core i9-14900K or Ryzen 9 9950X. The MTLR (Micro Tolerance Load Regulation) ensures rock-solid voltage stability during transient spikes from GPU power draw. Second, professionals running AI/ML training or 3D rendering on multi-GPU workstations (e.g., two or more RTX 6000 Ada or RTX 5090 cards). The high efficiency reduces electricity costs over long runs, and the dual 12V-2x6 connectors eliminate the need for messy adapters. Third, future-proofing enthusiasts who want a single PSU that can handle any conceivable upgrade for the next 10+ years. A 1600W unit ensures you won't need to swap the PSU even if next-gen components draw more power. ## Alternatives
Direct competitors include the Corsair HX1500i (1500W, 80 PLUS Platinum) and the be quiet! Dark Power Pro 13 1600W (80 PLUS Titanium). The Corsair offers digital monitoring via iCUE software but falls short on capacity and efficiency. The be quiet! Dark Power Pro 13 matches the Titanium efficiency and offers even lower noise levels, but its warranty is 10 years, two years shorter than the Seasonic. If you value the longest warranty and dual 12V-2x6 connectors, the Seasonic PRIME TX-1600 is the better pick.

Things to Consider

1600W is far more than what a single-GPU gaming PC needs. For a typical build with one mid-to-high-end GPU, a 1000W Platinum PSU would be sufficient and significantly cheaper. The 210mm depth can cause fitment issues in smaller cases; always verify clearance before buying. Additionally, the 12V-2x6 connectors are not backward-compatible with older GPUs without adapters, though standard PCIe cables are included for those. If you don't plan on running dual high-end GPUs or extreme overclocking, this PSU may be overkill.
