Frequently Asked Questions

Can the Prime PX-1600 power a flagship or dual-GPU build?
Yes. It provides two native PCIe 12VHPWR cables rated up to 600W each, and with 1600W on a single 133A 12V rail it easily powers a flagship GPU with headroom, or a demanding dual-GPU / AI workstation.
Is the Prime PX-1600 quiet and fully modular?
Yes. It is fully modular, and its 135 mm fan uses Digital Hybrid control that stays completely off under low and medium load for silent operation.
Will it fit in my case?
It is a full-size unit at 210 mm deep, longer than a standard ATX PSU, so confirm your case lists clearance for a 210 mm power supply before buying.
How is it different from the Prime TX-1600?
The PX-1600 is 80 PLUS Platinum, while the TX-1600 steps up to the higher Titanium efficiency. Both share the same Prime platform, dual 12VHPWR cables and 12-year warranty, so the PX is the more cost-effective flagship choice.
Singular Expert Insight
The Prime PX-1600 brings Seasonic's reference-grade Prime platform to a Platinum price point: maximum 1600W, dual 12VHPWR cables, Japanese capacitors and a 12-year warranty. It is the right choice for an extreme flagship or multi-GPU build where you want top-tier reliability without paying for the Titanium tier. Step up to the Prime TX-1600 for the highest 94% Titanium efficiency, or down to a 1000-1300W unit for a typical high-end single-GPU system. Pair it with a flagship graphics card or compare wattages across our power supplies.

Buyer's Guide

Buy it if
You are building an extreme flagship or multi-GPU rig and want maximum 1600W, Platinum efficiency, dual 12VHPWR cables and a 12-year Seasonic warranty.
Skip it if
You have a single mid-range or high-end GPU (1600W is overkill), or a compact case that cannot fit a 210 mm-deep PSU.
Also consider
The Prime TX-1600 for higher Titanium efficiency, or a 1000-1300W unit for a typical high-end single-GPU build.
