CORSAIR CX750M (2025) Power Supply: Affordable Power for Next-Gen GPUs

The CORSAIR CX750M (2025) is a semi-modular ATX 3.1 power supply designed to support the latest GPUs, including the NVIDIA RTX 50-series. With a native 12V-2x6 cable, Cybenetics Bronze efficiency, and a low-noise 120mm fan, it delivers reliable power without breaking the bank.

Native 12V-2x6 Cable

Say goodbye to adapters. The included 12V-2x6 cable is fully compatible with NVIDIA RTX 50-series GPUs and also supports 40-series cards. This means less clutter and a cleaner build.

Ample Power for High-End Systems

The CX750M provides up to 600W of GPU power through a single cable, enough for the RTX 5070 and 5070 Ti, as well as the RTX 4070 and 4080 lineups. The 750W total output is perfect for mid-to-high-end gaming rigs.

Latest Standards Compliance

ATX 3.1 and PCIe 5.1 compliance ensures the power supply is future-proof, meeting the latest requirements for power delivery and connectivity. This provides reliable power throughout its long lifespan.

Semi-Modular Design

Main power cables are attached, but all other cables are modular, so you only use what you need. This keeps your case tidy and improves airflow.

Quiet and Cool Operation

The 120mm fan spins silently under low and medium loads, ensuring near-silent operation. At full power, it still maintains efficient cooling with minimal noise.

Who It’s For

Builders who need a reliable, affordable power supply for their gaming PC. Perfect for systems with RTX 50-series or 40-series GPUs, and anyone who values a clean, quiet build.

Frequently Asked Questions

Will the CX750M work with my RTX 5070 graphics card?

Yes, the CX750M includes a native 12V-2x6 cable that directly powers RTX 50-series GPUs like the RTX 5070. It provides up to 600W of GPU power, which is more than enough for that card.

Is the CX750M quiet under load?

The 120mm fan spins silently under low and medium loads. Under heavy loads, the fan speed increases, but noise levels remain reasonable for a 750W unit.

What does semi-modular mean?

It means the essential cables (ATX 24-pin, CPU power) are permanently attached, while the other cables (SATA, PCIe, etc.) can be removed. This reduces cable clutter in your case.

Is this power supply future-proof?

Yes, it's ATX 3.1 and PCIe 5.1 compliant, and includes the 12V-2x6 connector, so it's ready for the latest hardware.

Quiet and reliable

The CX750M is a solid PSU. It runs silent even under load, and the semi-modular cables make cable management easy. My system has been stable for months. Great value.

Good PSU, but cables are a bit stiff

Works flawlessly with my RTX 4070. The 12V-2x6 cable is a nice addition. However, the SATA cables are stiff and hard to bend. Overall, a good buy.

Sleek and functional

The black finish is nice, and it's compact enough for my mid-tower. Cybenetics Bronze is decent for the price. I've had no issues so far.

Works but fan is audible

Powers my system fine, but the fan is a bit louder than I expected, especially under load. It's not terrible, but I notice it in a quiet room.

No complaints

Installed it in a new build with a 4070 Ti Super. Plenty of power, connectors are well-labeled. The low-noise fan is indeed quiet. Would recommend.

Great upgrade from old PSU

My old PSU died, so I picked this up. It runs my entire system smoothly, even during heavy gaming sessions. The modular cables helped me keep my case clean.

Coil whine issue

I hear a persistent coil whine whenever the system is on. It's annoying and not what you'd expect from a reputable brand. I'm returning it for a replacement.

Solid choice, minor cable length

The PSU is reliable and the 12V-2x6 cable works with my GPU. However, the CPU cable is a bit short for my full-tower case. Managed with extensions.

Perfect for mid-range builds

I have a Ryzen 7 and RTX 4080, and this supplies plenty of power. Bronze efficiency is fine. The fan is silent in idle. Great PSU for the price.

Almost perfect

Good build quality, performs as expected. Only downside is the sleeving on the cables could be nicer, but that's minor. I'm happy with it.
