Corsair HX1200i SHIFT 1200W 80+ Platinum ATX 3.1 Power Supply, Fully Modular

Corsair HX1200i SHIFT is a high-end power supply unit for serious gaming and workstation configurations, where stability and efficiency are more important than anything. With 1200W power and 80+ Platinum certification, you get a PSU that easily handles powerful GPUs and lots of peripherals without overheating. The focus is on reliable and clean power delivery under varying loads, plus good energy efficiency. The fully modular design makes cable management significantly easier, especially in more complex cases.

What you get

With 1200W, you have enough resources for systems with multiple NVMe drives, many fans, and a powerful CPU + high-end GPU, without worrying about future upgrades. 80+ Platinum and up to 92% efficiency mean less heat loss and lower power consumption during extended gaming or rendering. Thanks to Active PFC, the power supply maintains more stable voltage and handles network fluctuations better – important if the machine runs frequently under load. The modular design allows you to include only the necessary cables, which improves airflow and eases maintenance. The compact sizes for this class 200 x 150 x 86 mm make it suitable for most ATX cases.

• 1200W power provides a serious reserve for high-end GPUs, powerful CPUs, and rich peripherals, without risk of power shortage at peak consumption.
• 80+ Platinum certification means very high efficiency and less energy loss as heat under typical load scenarios.
• Up to 92% efficiency helps with lower electricity bills and a cooler system during long gaming sessions or heavy productive work.
• Fully modular design allows you to use only the necessary cables, making the build cleaner and improving airflow in the case.
• Active PFC improves the power factor and stabilizes operation during electrical grid fluctuations.
• Rich connector set with 1 x 20+4 PIN, 2 x 4+4-pin ATX/EPS, 4 x PCI-Express 6+2-pin, 8 x SATA, and 6 x 4 Pin Peripheral covers modern motherboards, powerful graphics cards, and several storages.
• Dimensions 200 x 150 x 86 mm make it compatible with most standard ATX cases, despite the high power.

Who it's suitable for

This power supply is suitable if you're building a high-end gaming build, streaming/rendering machine, or workstation, where stability under load is critical. It makes sense if you plan future upgrades and want a PSU that you won't replace with every serious change. If you're assembling a budget or mid-range configuration with moderate energy consumption, this power may come in handy.

The strongest combination here is the high 1200W power, 80+ Platinum efficiency, and fully modular design – a setup that gives you stability, flexibility, and peace of mind for a serious build and long-term use.
