HX1000 1000 W Platinum ATX power supply

The Corsair HX Series HX1000 delivers 1000 W through an ATX12V v2.4 and EPS12V 2.92 design. It uses a single 135 mm fluid dynamic bearing fan with Zero RPM mode for silent operation at low loads. All Japanese capacitors ensure tight voltage regulation and long-term reliability. The fully modular cable set simplifies builds and cable management.

Upgrade from lower efficiency or semi-modular units

Replacing a Bronze or Gold rated supply with this Platinum unit cuts waste heat and lowers running cost. The switch from fixed cables to full modularity removes unused connectors and improves airflow. The jump is worth it when building a high-end system that demands stable 12 V delivery and quiet operation under sustained load.

Suited for high-performance PCs needing 1000 W

This unit fits builders who want Platinum efficiency, zero-fan silence at idle, and a 180 mm depth that suits most ATX cases. It provides eight 6+2-pin PCIe connectors and six SATA power plugs for multi-GPU or storage-heavy configs. Users with smaller cases or modest power needs should verify clearance and consider a lower wattage model.

Questions about this item

What case clearance does the 180 mm length require?

The power supply measures 180 mm long so the case must provide at least that much clear depth behind the motherboard tray for the unit to sit without pressing on cables or drive cages.

Which cables must be attached during installation and what is the common oversight?

Connect the 24Pin main connector, the required 6+2-Pin PCI-Express leads and any SATA power cables; the step often missed is setting the +12V rail switch to the desired Single or Multi Rail mode before powering on.

What component determines the unit's long-term reliability and when is it rated to last?

The 135 mm fluid dynamic bearing fan and all Japanese capacitors are rated for 100000 hours MTBF, so under normal loads the fan is the only moving part likely to need replacement after many years of service.
