Corsair, a leading manufacturer of gaming peripherals and components, has significantly revamped its product lines in recent years. This includes advancements in wireless technology with Slipstream for gaming mice, and smarter Hydro Series coolers with iCUE integration. Even the budget-friendly K68 RED LED keyboard has been replaced by the upgraded K60 Pro. Following this trend, Corsair has also revitalized its CX series of power supplies, introducing a fresh design and improved performance to better meet user needs. The Corsair CX750F RGB, the most powerful offering in the updated CX lineup, aims to power high-end and demanding PC systems. This begs the question: can a CX series PSU truly handle top-tier components? Let’s delve into a closer look at this power supply.

Corsair CX750F RGB: A Muscular and Powerful Design

While Corsair is renowned for its high-end power supplies capable of powering the most demanding PCs, their previous generation of budget and mid-range PSUs, including some CX models, didn’t always meet user expectations. With the redesigned CX series, Corsair appears to have taken a more comprehensive approach. Departing from the traditional plain, boxy design, the CX750F RGB adopts a more robust, muscular aesthetic reminiscent of the higher-tier RM series, which has garnered positive feedback from enthusiast users.

The first impression is of a noticeably thicker and more robust steel chassis compared to the previous flatter, thinner design that felt somewhat flimsy. The interlocking design of the chassis panels creates a unified and secure structure, enhancing overall rigidity. Attempting to disassemble the unit without specialized tools proved to be a futile exercise, further underscoring the robust construction.

Unlike most conventional power supplies, the CX750F RGB adopts a top-mounted fan orientation, similar to recent high-end PSUs like the ROG Thor 850W Platinum. Corsair has equipped the CX750F RGB with a 120mm RGB fan. Uniquely, this fan features a dedicated switch on the back of the unit to disable the RGB lighting independently. This design showcases the attractive RGB lighting, but with many modern PC cases concealing the PSU, this feature might not always be visible. Users looking to showcase the RGB lighting will need a compatible case with a window or cutout above the PSU shroud, such as Corsair’s 4000X RGB and other 4000 series cases.

Connectivity and Control

The front panel features a comprehensive array of connectors, including four 8-pin CPU/PCI-E connectors, two motherboard connectors, and three SATA connectors. A key differentiator for the new CX series is the ability to control the RGB fan lighting through the RGB In connector. This allows synchronization with CORSAIR iCUE Lighting Node CORE (sold separately or included with cases like the 4000X RGB) or direct connection to compatible motherboard ARGB headers, offering greater customization compared to other RGB-equipped PSUs.

The included cables are primarily flat ribbon-style, with the exception of the sleeved motherboard cable for added durability and protection. The CX750F RGB is fully modular, unlike the semi-modular design of the previous CX750M, offering greater convenience and cable management.

Performance and Testing

The CX750F RGB utilizes high-quality internal components manufactured by HEC, incorporating modern technologies and adhering to the 80 Plus Bronze efficiency standard. Testing involved powering demanding systems with CPUs like the AMD Ryzen 7 5800X and Ryzen 9 5900X, paired with GPUs ranging from the Sapphire Pulse RX 5600 XT 6G to the Gigabyte RTX 3080 Vision OC 10G.

The PSU performed admirably, consistently delivering sufficient power to both CPU and GPU under heavy load without any voltage drops or shutdowns. Even with the system drawing over 650W with the Ryzen 9 5900X boosting to 4.7GHz, the CX750F RGB remained stable. The fan operated quietly throughout testing, barely audible over the GPU and AIO cooler fans.
