1200W ATX 3.0 Power Supply for PCIe Gen 5 Builds

This fully modular unit delivers 1200W continuous output at 45°C and meets Intel ATX 3.0 specifications. It is aimed at enthusiasts building high-end systems that require a native 12VHPWR connection for next-generation graphics cards.

Full Modular Design with Native 12VHPWR Cable

A 16-pin 12VHPWR cable rated for 600W is included in the box alongside black low-profile flat cables for 24-pin, PCIe and SATA devices. The single +12V rail simplifies cable routing, while the 150mm chassis depth fits most standard ATX cases.

600W 12VHPWR Connector Decides GPU Compatibility

The native 12+4-pin modular interface can deliver up to 450W to a PCIe 5.0 graphics card and 600W total through the connector. Verify your GPU's power requirement against this 600W limit before purchasing.

Questions about this item

How can I confirm the 120 mm fluid dynamic bearing fan is operating correctly once the PSU is installed?

The Smart Zero Fan mode keeps the fan off at low loads; it spins up automatically when power draw rises, so you will hear it start under heavy GPU or CPU load.

Which cables are included in the box and what must I purchase separately for a typical build?

The fully modular unit ships with a 24-pin ATX cable, five 6+2-pin PCIe cables, a 12VHPWR cable rated for 600 W, and twelve SATA power connectors; no extra cables are required for standard ATX 3.0 builds.

Should I choose the 1200 W version or a lower-wattage model for a PCIe 5.0 graphics card?

The 1200 W model provides a native 12VHPWR connector delivering up to 450 W to the GPU and supports 200 % power excursion, making it the appropriate choice for high-end PCIe 5.0 cards.
