High-End Gaming, Workstation, Enthusiast Builds, Multi-GPU Systems

Overview

The Seasonic PRIME TX-1000 is a flagship 1000W fully modular Titanium-rated power supply built for uncompromising high-end systems. It drives a single powerful +12V rail at 83A with Micro Tolerance load regulation that keeps output within 0.5%, underpinned by an Active PFC + Full Bridge LLC + synchronous rectification + DC to DC topology and Japanese 105°C capacitors. A 135mm Fluid Dynamic Bearing fan with Premium Hybrid semi-passive control ensures near-silent operation under light loads, while the extensive cable set offers a native 12VHPWR plus six PCIe 6+2 connectors to handle modern and multi-GPU setups. Seasonic stands behind the PRIME TX-1000 with a 12-year warranty and a 100,000-hour MTBF at 25°C.
