Corsair RM750x (2024) Power Supply Review: A Quiet, Efficient, and Reliable PSU

When building a high-performance PC, choosing the right power supply unit (PSU) is crucial for both system stability and longevity. The Corsair RM750x (2024) stands out in the crowded PSU market, offering a balance of efficiency, quiet operation, and reliability, making it a solid choice for gamers, PC enthusiasts, and those building workstations. In this review, we’ll take a detailed look at what makes the Corsair RM750x a top-tier PSU in 2024.

Key Features and Performance

The Corsair RM750x (2024) delivers 750 watts of continuous power, which is enough for most mid- to high-end PC builds, including those with powerful GPUs like the NVIDIA RTX 4070 or AMD RX 7800 XT. This is a sweet spot for users who want to ensure ample headroom for overclocking and future upgrades without going overboard with wattage.

What truly sets the RM750x apart is its 80+ Gold efficiency certification. This rating indicates that the PSU operates at an impressive 90% or higher efficiency at typical loads, minimizing energy waste, keeping electricity costs low, and reducing excess heat generation. In practice, this means the PSU will waste less energy in the form of heat, allowing for quieter operation and improved overall system cooling.

Fully Modular Design for Better Cable Management

A major selling point of the Corsair RM750x is its fully modular design. This means that you only need to connect the cables you actually need for your system, helping to reduce clutter inside your case. Fewer cables mean better airflow and a cleaner aesthetic, which is especially important in systems where cooling is paramount. For PC builders, this modular approach simplifies cable management and leads to a more organized, efficient build. Corsair’s use of high-quality, soft-touch cables also ensures that connectors are easy to handle and secure.

Silent Operation with Zero RPM Fan Mode

One of the standout features of the RM750x (2024) is its zero RPM fan mode, which ensures that the fan only spins when the PSU reaches a certain load threshold. This results in almost silent operation during light loads or when your system is idle. Even under heavier loads, the 135mm fan with a fluid dynamic bearing helps keep the noise level to a minimum. This makes the RM750x a great option for those who prioritize a quiet, noise-free computing experience, such as in home theaters or gaming rooms.

Robust and Reliable Components

Corsair has a long-standing reputation for using high-quality components, and the RM750x (2024) is no exception. The unit features 100% Japanese capacitors, which are known for their durability and long lifespan. These high-end components contribute to the power supply’s reliability and stability, ensuring that it can handle high-power loads without degradation in performance. Whether you’re running demanding workloads, heavy gaming sessions, or even video rendering tasks, the RM750x is designed to deliver stable, consistent power.

Safety and Protection Features

A quality PSU is only as good as its ability to protect your valuable components from power issues. The RM750x comes equipped with a full suite of protection features, including over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-power protection (OPP), short-circuit protection (SCP), and over-temperature protection (OTP). These protections ensure that your system remains safe from electrical failures, offering peace of mind when using high-end components or pushing your system to its limits.

Sleek and Compact Design

Another appealing aspect of the Corsair RM750x is its aesthetic design. The PSU features a minimalist, matte black finish with subtle branding, making it an ideal choice for users who prefer a more understated look for their builds. The compact size of the RM750x also makes it easy to install in most cases, even in smaller chassis, without compromising on performance.

Pros and Cons of the Corsair RM750x

Pros:

• 80+ Gold Efficiency: Minimizes energy waste and keeps power delivery stable.
• Zero RPM Fan Mode: Ensures near-silent operation during low to medium loads.
• Fully Modular Design: Improves cable management and system airflow.
• High-Quality Components: 100% Japanese capacitors for durability and reliability.
• Comprehensive Protection: Multiple safety features to protect your components from electrical issues.
• Compact and Sleek: Ideal for both aesthetic and functional PC builds.

Cons:

• Price: The RM750x is priced at a premium compared to non-modular or lower-efficiency models. However, the price is justified by its build quality and features.
• Not Ideal for Extreme High-Wattage Setups: If you’re building a system with multiple GPUs or a very high-end CPU, you might need more than 750W to handle those extreme power demands. In most cases, though, 750W is sufficient.

Final Thoughts: Should You Buy the Corsair RM750x (2024)?

The Corsair RM750x (2024) is an outstanding power supply that offers a combination of efficiency, quiet operation, and long-term reliability.
