ASUS ROG THOR 1200W 1200P3-GAMING-E 24-pin ATX ATX Black Power Supply

ASUS ROG THOR 1200P3 is a high-end ATX power supply with 1200 W power, aimed at serious gaming and workstation configurations. It combines 80Plus Platinum and Cybenetics Platinum efficiency with ATX 3.1 and PCIe 5.1 compatibility, so you can be assured for the next generations of graphics cards. In the case, you get a fully modular design with etched cables, a large 135 mm fan, and low noise levels certified with Cybenetics Lambda A++. There are also extras for enthusiasts – an OLED display for real-time consumption and AURA Sync ARGB lighting.

What you get

With a real 1200 W output power and ATX 3.1 / PCIe 5.1 compatibility, this power supply is ready for top graphics cards with a 16-pin 12V-2x6 PCIe connector that comes in the package (ROG Equalizer cable). Active PFC and high efficiency (80Plus Platinum + Cybenetics Platinum) mean less heat loss, lower power consumption, and more stable voltages under load. The 0dB technology and the fan mode selection button give you the choice between completely silent idle and more aggressive cooling when needed. The fully modular cables help with clean cable management and better airflow, especially in more compact or tightly packed ATX cases. The OLED display for real-time consumption is useful if you want to monitor the system under various loads without additional software.

• 1200 W output power – sufficient for a high-end CPU + flagship GPU build with room for overclocking and future upgrades.
• 80Plus Platinum and Cybenetics Platinum efficiency – lower losses and less heating, which supports the long life of components.
• ATX 3.1 and PCIe 5.1 compatibility – ready for modern and future graphics cards, including via 1 x 16-pin 12V-2x6 PCIe cable.
• 135 mm fan with dual-ball bearings – reliable active cooling designed for long life under high load.
• 0dB technology and 0dB Fan button – the fan stops at low load for completely silent operation and you choose when to activate it.
• Fully modular etched cables – connect only the necessary connectors, reduce cable chaos, and improve airflow.
• OLED display and AURA Sync ARGB lighting – see the current consumption of the system and synchronize the lighting with other components.
• Cybenetics Lambda A++ – confirmed very low noise level, suitable for quiet or showcase configurations.
• Full set of protections (OPP, OVP, UVP, SCP, OCP, OTP) – protect your expensive components from power anomalies.
• Compact ATX dimensions 190 x 150 x 86 mm and weight 2.37 kg – dense, heavy, and stable PSU that fits in standard ATX cases.

Who it is suitable for

This power supply is for serious gaming and creator builds that pursue high-end GPUs, powerful CPUs, and a lot of peripherals, without compromising on noise, stability, and future compatibility. It is suitable if you want an ATX 3.1 foundation ready for PCIe Gen 5.0/5.1 cards and want to see the real consumption of your system. It is not a particularly logical choice for budget configurations or low consumption systems, where much of its potential will remain unused.

The combination of 1200 W power, dual Platinum efficiency, and ATX 3.1 / PCIe 5.1 support makes the ROG THOR 1200P3 a solid foundation for a long-term high-end build. And the silence, modular cables, and OLED display distinguish it as a component that not only 'gets the job done' but gives you real control and visibility over the system.
