1300 W ATX12V power supply for high-end builds

This fully modular ATX12V unit delivers 1300 W through a single +12 V rail. It targets enthusiasts building workstations or multi-GPU systems that need clean, high-current power. The 160 mm length fits most mid-tower and larger cases. Japanese capacitors and a 140 mm hydraulic bearing fan support long-term reliability.

Native 16-pin cable and full modular cabling

A native 12VHPWR cable rated for 600 W enables direct connection to PCIe Gen 5.0 graphics cards without adapters. Full modularity lets builders install only the cables they need, reducing clutter and improving airflow. The package includes eight 6+2-pin PCIe connectors and twelve SATA connectors for drives and peripherals.

1300 W continuous with 200 % excursion headroom

The platform sustains 1300 W continuous output and can handle 200 % total power excursion per the Intel ATX 3.0 design guide. GPU power excursions up to 3x are supported on the 16-pin connector. Efficiency reaches 90 % at typical load and 70 % at low load, while active PFC maintains a power factor above .9 across 100-240 V input.

Questions about this item

How often will the 140 mm hydraulic bearing fan need replacement?

The fan uses a hydraulic bearing rated for long life, and the unit's MTBF exceeds 100,000 hours, so replacement is unlikely during typical ownership.

What limits continuous output before protection triggers?

The single +12 V rail delivers the full 1300 W; sustained loads at that level are protected by OPP and OTP, which shut the unit down if limits are exceeded.

How loud and hot does the 140 mm fan run under all-day load?

The smart hydraulic bearing fan adjusts speed to load and temperature, keeping noise low at typical loads while maintaining safe thermals during extended 1300 W operation.
