Vertex PX-1000 1000W ATX power supply

The Seasonic Vertex PX-1000 delivers 1000W of continuous power in a standard ATX form factor. It carries 80+ Platinum certification for high efficiency across typical loads. The unit suits workstations and high-end gaming builds that demand stable, high-wattage output.

Fully modular cabling and compact ATX dimensions

All cables detach from the unit, so only the required leads occupy the case interior. This simplifies routing and improves airflow in tight layouts. Builders who need more than 1000W or a smaller SFX footprint should consider alternative form factors.
