Seasonic VERTEX PX-1000 1000W 80+ Platinum ATX 3.0 power supply

High-efficiency ATX 3.0 power supply

The Seasonic VERTEX PX-1000 delivers 1000 W of continuous power with 80 PLUS Platinum efficiency. It targets builders assembling high-performance systems who need stable voltage regulation and full modular cabling. The unit includes a native 12VHPWR cable for modern graphics cards. It suits users who value certified components and a long MTBF rating.

Fully modular design simplifies cable routing

Only the cables required for the build need to be connected, reducing clutter inside the chassis. The 160 mm depth fits standard ATX layouts without intruding on drive bays or large coolers. Active PFC handles 100-240 V input across 50/60 Hz automatically. Japanese 105 °C capacitors support tight ±3 % regulation on the 12 V, 5 V and 3.3 V rails.

Hybrid fan control balances thermals and noise

The 135 mm FDB fan stays idle during light loads and spins up only when temperature demands it. Platinum-rated efficiency lowers waste heat, easing the thermal load on the case airflow. Over-voltage protection adds a safety layer during unexpected transients. The platform is rated for 100,000 hours MTBF under normal operating conditions.
