Corsair 750W RM750x 24-pin ATX White power supply

Corsair RMx Series RM750x is a 750 W ATX power supply in white color, 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 organized cable management even in smaller cases. Active PFC and over 90% efficiency at typical loads give you stable and economical system power. The RMx series is oriented towards low noise and reliability with 100% Japanese 105°C capacitors and multiple protections.

What you get

With power from 750 W and four separate 8-pin PCIe (6+2) connectors, you get a serious base for a modern graphics card, plus an option for a more aggressive upgrade in the future. The two 8-pin EPS/ATX12V (4+4) CPU connectors allow you to comfortably power 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 only include what you actually use, and the case stays clean and ventilated. The 135 mm rifle bearing fan with optimized fan curve and Zero RPM Fan Mode means that at lower loads the power supply often works practically silently, which is a plus for quiet gaming and workstation machines. Built-in protections (OVP/UVP/SCP/OPP/OTP) and 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 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 facilitates airflow and building a clean, aesthetic white build.
• 135 mm rifle bearing fan with Zero RPM Fan Mode – the fan stops completely at low load for quiet operation and turns on 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 FDD adapter cover from high-end GPU to a stack of SSD/HDD and peripherals.
• 100% Japanese 105°C capacitors (industrial-grade) – designed for higher thermal stability and longer life during extended operation.
• Multiple protections (OVP/UVP/SCP/OPP/OTP) and MTBF 100,000 hours – protect your components from overvoltage, short circuit, overload, and overheating, with a focus on long-term reliability.

Who it is suitable for

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 cables do not spoil the view. If you plan an extreme multi-GPU setup or super heavy overclock configurations, it may make sense to look at higher wattage, but for one 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 Corsair RM750x a very meaningful foundation for a serious, cleanly assembled and reliable gaming or workstation build.
