SKU CH-1CPE-4GSTX

A 1200W ATX 3.1 Platinum power supply with GaN MOSFETs, smart voltage regulation and a native 12V-2x6 connector for PCIe 5.0 graphics cards

  • TypeATX
  • GaN MOSFETs deliver superior power efficiency and cooler operation
  • Patented smart voltage regulator ensures stable graphics-card power
  • Large ROG heatsink lowers component temperatures and noise
  • Dual ball-bearing fans last up to twice as long as oil-sealed designs
  • ATX 3.1 compliant and PCIe 5.0 ready with native 12V-2x6 connector

ROG STRIX 1200W Platinum PSU

This ASUS power supply delivers 1200 watts through an ATX form factor. It uses gallium nitride MOSFETs and a patented smart voltage regulator for stable, efficient power delivery. A large ROG heatsink covers critical components to lower temperatures. Dual ball-bearing fans and 0dB technology keep operation quiet during light loads.

Ideal for high-end ATX 3.1 builds

The unit suits builders assembling systems that demand ATX 3.1 compliance and a native 12V-2x6 connection for modern graphics cards. It fits quiet-focused rigs thanks to the semi-passive fan mode. Buyers who need a smaller form factor such as SFX or a lower wattage for compact cases should look elsewhere.

Integrates into ATX 3.1 systems

The supply slots into standard ATX cases and provides the 12V-2x6 connector required by PCIe 5.0 graphics cards. GaN components allow a cleaner internal layout, freeing space for cable routing. Ensure the chassis accommodates a full-size ATX unit and that the motherboard supports the ATX 3.1 power specification.

Questions about this item

What motherboard power connector does the 1200W ATX supply require?

It uses the standard ATX 24-pin motherboard connector plus the required EPS 12 V cables for the CPU.

Will the native 12V-2x6 output work with my existing PCIe 8-pin graphics card?

Yes, the 12V-2x6 connector is backward compatible with 8-pin PCIe plugs through an adapter or the cable’s split end.

How can I confirm the fan is running in 0dB mode during light loads?

The fan stops completely below the thermal threshold; you will hear no spin noise while the system idles or browses the web.
