The Seasonic PRIME PX-1600 is a premium 1600W ATX 3.0 power supply designed for high-performance gaming and workstation builds. It features full ATX 3.0 and PCIe 5.0 compliance with 2x native 12VHPWR (16-pin) connectors rated at 600W each, perfect for modern GPUs like RTX 4090. Achieving 80 PLUS Platinum certification (92% efficiency at 50% load), it uses 105°C-rated Japanese electrolytic capacitors for reliability and longevity.
Key highlights include Micro Tolerance Load Regulation (MTLR) under 0.5% for stable power delivery, fully modular cabling with PVC embossed sleeves for clean builds, and a 135mm Fluid Dynamic Bearing (FDB) fan with advanced digital hybrid control for silent operation. The cable-free PCB connection enhances output quality. Backed by a 12-year warranty, it’s built for demanding setups with top-tier protection (OVP/OCP/OPP/SCP/UVP).
