When it comes to building the ultimate gaming rig or a powerhouse workstation, a power supply is your silent hero, and there’s no better time to upgrade than Amazon Prime Days. For a limited time, the ROG Strix 1200W Platinum PSU is available at a significant discount, dropping 16% off MSRP down to $214.99 (USD). Whether you’re aiming to maximize the performance of the latest NVIDIA RTX 50 Series or AMD Radeon RX 9000 Series GPUs, this platinum-rated power supply is engineered to be the foundation of any high-end build.
The heart of a modern gaming PC
Ask any enthusiast or hardware reviewer: today’s graphics cards demand not only raw wattage, but consistently clean, efficient power. The ROG Strix 1200W Platinum PSU delivers on all fronts. Its formidable 1200-watt capacity is designed to comfortably handle any next-gen GPU on the market alongside a powerful CPU. The unit’s 80 PLUS Platinum certification ensures up to 92% efficiency at half load, reducing waste heat, allowing for quieter operation, and keeping energy bills in check, all benefits that every gamer can appreciate.
A key weapon in the ROG Strix Platinum PSU’s pursuit of efficiency is its innovative GaN MOSFET. It delivers superior power efficiency by up to 30%, resulting in lower energy waste. Plus, the smaller size of GaN MOSFET allows for a more organized internal layout within the PSU. This optimized design provides space for larger heatsinks and enhanced airflow, improving heat dissipation within the PSU.
Built with next-gen GPUs in mind
Modern graphics cards have evolved not just in performance but also in their power requirements. Top-shelf units like the ROG Astral GeForce RTX 5090 aren’t shy in their usage of high-end wattage to support the best frame rates and exceptional performance in AI and content creation workloads. When you plug in a new card equipped with a 16-pin connector, the ROG Strix 1200W Platinum PSU is ready. With native PCIe 5.0 (12V-2×6) support, you get clean, stable power delivery straight to your GPU, no adapters or cable clutter required.
This PSU is ready to power any rig you can assemble, no matter what kind of graphics card (GPU) you put under the hood. That’s where the GPU-FIRST intelligent voltage stabilizer comes into play. It ensures that even an overclocked graphics card always has the stable power flow it needs to perform at peak capacity during intense gaming sessions, providing 45% more stable flow to the GPU versus without the stabilizer. And if you prefer a classical CPU-focused voltage sensor, you can disconnect the Strix Platinum series’ IVS cable.
Robust cooling keeps the action going
Long gaming sessions and intense creative workloads generate heat, especially when high-powered components are pushed to their limits. The ROG Strix 1200W Platinum PSU features beefy ROG heatsinks and a 135mm Axial-tech fan with dual ball bearings, ensuring both efficient cooling and whisper-quiet operation. The fan only spins up when needed, thanks to the 0dB fan mode. It keeps your battle station silent during lighter workloads, only ramping up airflow during marathon gaming sessions or heavy rendering tasks.
Premium components, unrivaled reliability
What sets the Strix PSU apart are top-shelf components. Inside, you’ll find 100% Japanese capacitors, known for their stability and endurance under heavy load. A proprietary PCB layout minimizes electrical noise and ripple, safeguarding your prized components and delivering rock-solid, consistent voltage.
We back the Strix 1200W Platinum with a 10-year warranty, so you know this investment is built to last. And with heavy-duty protection features, including OPP (Over Power Protection), OVP (Over Voltage Protection), SCP (Short Circuit Protection), and more, your system is shielded from the unexpected.
Flexible connectivity and modular design
Anyone who’s built a PC knows the struggle: managing a web of cables while trying to maintain airflow and a clean aesthetic. The fully modular design of the ROG Strix 1200W Platinum PSU means you only use the cables you need, reducing clutter and maximizing airflow. The included cables are sleeved for durability and style, and the unit offers a generous slate of connectors.
