Corsair 750W RM750x 24-pin ATX White power supply

The Corsair RMx Series RM750x is a 750 W ATX power supply in white, aimed at mid-range to high-end gaming and workstation configurations. It combines 80 PLUS Gold efficiency with fully modular flat cables and a compact ATX chassis, which facilitates tidy cable management even in smaller cases. Active PFC and over 90% efficiency at typical loads provide stable and economical power delivery to the system. The RMx series is focused on low noise and reliability with 100% Japanese 105°C capacitors and multiple protections.

What you get

With a power output of 750 W and four separate 8-pin PCIe (6+2) connectors, you get a solid foundation for a modern graphics card, plus the option for a more aggressive upgrade in the future. The two 8-pin EPS/ATX12V (4+4) CPU connectors allow you to comfortably power more demanding motherboards and processors without worrying about stability under load. The fully modular design with flat white cables makes assembly and cable management much easier — you connect only what you actually use, and the case remains clean and well-ventilated. The 135 mm rifle bearing fan with an optimized fan curve and Zero RPM Fan Mode means that at lower loads, the power supply often operates practically silently, which is a plus for quiet gaming and workstation machines. The built-in protections (OVP/UVP/SCP/OPP/OTP) and an MTBF of 100,000 hours highlight the focus on long-term reliability.

• 750 W Power – sufficient for modern gaming and workstation systems with a powerful CPU and a serious GPU, including future upgrades.
• 80 PLUS Gold efficiency (>90% at typical load) – less heat loss, lower power consumption, and cooler operation of the power supply.
• Fully modular flat white cables – you use only the necessary cables, which improves airflow and the construction of a clean, aesthetic white build.
• 135 mm rifle bearing fan with Zero RPM Fan Mode – the fan stops completely at low loads for quiet operation and kicks in smoothly when needed.
• Rich connector set – 1 x 24-pin ATX, 2 x 8-pin EPS/ATX12V, 4 x 8-pin PCIe, 9 x SATA, 8 x Molex, and an FDD adapter cover everything from high-end GPUs to stacks of SSD/HDD and peripherals.
• 100% Japanese 105°C capacitors (industrial-grade) – designed for higher thermal resistance and a longer lifespan during prolonged operation.
• Multiple protections (OVP/UVP/SCP/OPP/OTP) and 100,000-hour MTBF – protects your components from overvoltage, short circuits, overloading, and overheating, with a focus on long-term reliability.

Who it is suitable for

The RM750x is a good choice if you are building a mid-range or high-end gaming PC, streaming, or workstation configuration and want a balance between power, silence, and efficiency. It is also suitable for more stylish white builds where the cables should not ruin the look. If you plan an extreme multi-GPU setup or super heavy overclocking configurations, it might make sense to look at a higher wattage, but for a powerful graphics card and a strong CPU, 750 W is a very good core.

The combination of 750 W power, 80 PLUS Gold efficiency, quiet operation with Zero RPM Fan Mode, and fully modular white cables makes the Corsair RM750x a very sensible foundation for a serious, cleanly built, and reliable gaming or workstation build.
