ASUS ROG STRIX 1200W 1200P-GAMING-E 20+4 pin ATX ATX Black, Multicolour Power Supply

ASUS ROG STRIX 1200P Gaming is a powerful 1200 W ATX power supply, aimed at high-end gaming and enthusiast configurations. It operates in a wide input range of 100–240 V, making it suitable for more unstable networks. With 80 PLUS Platinum and Cybenetics Platinum certifications, you get high efficiency and less heat loss. The format is standard ATX in a compact body of 160 x 150 x 86 mm, making it suitable for most mid and full tower cases.

What you get

With an output power of 1200 W and up to 100 A on the +12V rail, you can easily power high-end CPUs and modern GPUs with high peak loads, including PCIe Gen 5 cards via the native 12V-2x6 connector. ATX 3.1 / PCIe 5.1 compatibility means you are ready for the new generations of graphics cards, without adapters and compromises. The GaN MOSFET design and active PFC help achieve higher efficiency and more stable voltages under load. The fully modular, tinned OFC wires facilitate cable management and reduce losses, while the 0dB mode with a button gives you the choice between absolute silence under low load and more aggressive cooling when desired.

• 1200 W output power with up to 100 A on the +12V rail provides enough resources for high-end GPUs and multi-core CPUs without the risk of shortage.
• 80 PLUS Platinum and Cybenetics Platinum efficiency reduce losses and heating, which also helps for quieter operation.
• ATX 3.1 standard and PCIe 5.1 compatibility with native 12V-2x6 connector prepare you for current and future generations of graphics cards without the need for adapters.
• 135 mm Axial-tech fan with dual-ball bearings ensures long life and stable cooling, while 0dB technology stops the fan under low load for a quiet system.
• Fully modular design and tinned OFC cables allow you to connect only the necessary wires and keep the interior of the case tidy with better airflow.
• ROG EQUALIZER 12V-2x6 PCI-E cable with GPU-First design optimizes power delivery to the graphics card, which is critical for high power GPUs.
• Full protection (OPP, OVP, UVP, SCP, OCP, OTP) keeps your components safe from overload, overvoltage, short circuits, and overheating.
• MTBF >120,000 hours @ 25°C indicates long-term reliability, while a weight of 1.84 kg and dimensions of 160 x 150 x 86 mm make it convenient for a wide range of ATX cases.

Who it is suitable for

This power supply is for serious gaming and enthusiast builds with powerful GPUs, overclocked CPUs, and plenty of peripherals, where stability and efficiency are a priority. It is also suitable for configurations with long gaming/rendering sessions that keep the system under high load for extended periods. If you are building a basic budget build, this model is more of an overkill and you won't feel a real benefit from such a large capacity.

The combination of 1200 W power, ATX 3.1 / PCIe 5.1 compatibility, high-class efficiency, and quiet operation with 0dB mode makes ASUS ROG STRIX 1200P Gaming a very stable foundation for a serious, long-term high-end build.
