FAQ

Is the Prime PX-1600 compatible with the latest RTX 4090 graphics cards?

Yes. The PSU includes dual native 12V‑2×6 connectors that match the power requirements of RTX 4090 and other PCIe 5.1 GPUs without the need for adapters.

What does the hybrid fan mode do?

Hybrid mode allows the fan to remain off at low to moderate loads, using passive cooling to keep noise near zero. When temperatures rise, the fan ramps up automatically to maintain safe operating conditions.

How does the 12‑year warranty work?

Seasonic covers any manufacturing defects for 12 years from the date of purchase. If a failure occurs within this period, the company will repair or replace the unit at no cost, provided the PSU was used under normal conditions.

Can I use this PSU in regions with 110 V mains electricity?

Absolutely. The Prime PX‑1600 supports an input voltage range of 90‑230 V AC, making it suitable for both 110 V (North America) and 220‑240 V (Europe, Asia) power grids.

What makes Japanese capacitors better than standard electrolytic caps?

Japanese capacitors have lower equivalent series resistance (ESR) and tighter tolerance, which results in more stable voltage regulation, especially during rapid load changes common in high‑performance computing.
