1200 W ATX 3.1 power supply

The ASUS ROG-STRIX-1200P-GAMING-E is a fully modular ATX 3.1 power supply rated at 1200 W. It uses GaN MOSFETs to raise efficiency by up to 30 % and carries 80 PLUS Platinum plus Cybenetics Platinum certifications. A single +12 V rail delivers up to 100 A for stable high-current loads.

Ideal for high-end gaming and workstation builds

The unit suits systems that need a 16-pin 12V-2x6 GPU connector plus four 6+2-pin PCIe cables for multi-GPU or high-power graphics cards. It also provides two CPU 4+4-pin connectors, six SATA and three peripheral connectors for storage and accessories. Builds with limited case depth should verify the 160 mm length before purchase.

Headroom for flagship GPUs and heavy workloads

The 1200 W capacity comfortably handles a top-tier graphics card and overclocked CPU together, with the GPU-First voltage stabiliser improving delivery by up to 45 %. The fan stays off under light loads for 0 dB operation, while Cybenetics A noise certification keeps sound below 20 dB at higher loads. Protection circuits include OPP, OVP, UVP, SCP, OCP and OTP.

Questions about this item

What motherboard connector must my board have to use the 20+4-pin cable supplied with this PSU?

Your motherboard needs a standard 24-pin ATX socket; the 20+4-pin cable splits to fit either 20- or 24-pin headers.

Will the single 16-pin 12V-2x6 cable work with an older graphics card that only has 8-pin sockets?

The 16-pin cable is keyed for 12V-2x6 GPUs; for older cards use the four included 6+2-pin PCIe cables instead.

How can I confirm the 0 dB fan mode is active after I build the system?

At low load the fan stops completely; you will hear no spinning noise until power draw rises above the silent threshold.
