1500W ATX Titanium PSU

The Corsair AX1500i is a fully modular ATX12V v2.4 power supply rated at 1500 W with a single +12 V rail capable of 125 A. It carries 80 PLUS Titanium certification and achieves 94% efficiency under typical loads. A Digital Signal Processor manages voltage regulation and enables real-time monitoring through Corsair Link software.

Multi-GPU builders and workstations

This unit suits systems that demand up to ten PCIe 6+2 pin connectors and twenty SATA power connectors for dense storage arrays. The Zero RPM fan mode allows silent operation at low load. Builders needing fewer connectors or a lower maximum wattage should consider a smaller power supply.

Single +12 V rail at 125 A

The single-rail design delivers the full 1500 W through one +12 V rail rated at 125 A, simplifying cable routing for high-current graphics cards. Over-voltage and overload protection are included. MTBF is rated at 100000 hours.

Questions about this item

Does the Corsair AX1500i come with all cables needed for a motherboard, two CPUs and six graphics cards?

The box includes one 20+4 pin motherboard cable, two 4+4 pin CPU cables, six PCIe 6+2 pin GPU cables, five SATA cables, three 4-pin peripheral cables and two floppy adapters.

The specs list ten PCIe connectors but only six GPU cables — how do I use the remaining four?

Each of the six supplied cables carries two 6+2 pin heads, giving twelve total heads; the ten-connector rating means the unit can power up to ten PCIe devices simultaneously.

What does the 1500 W rating mean when the +12 V rail is rated for 125 A?

The single +12 V rail can deliver 125 A, which equals the full 1500 W capacity, so the headline figure is available to GPUs and CPUs without rail balancing.
