Total Score

Today in our Corsair CX750F RGB 750W PSU review, we’ll talk about the product’s performance and other important information about it.

We’ll also talk about the colours we’ll see with their advertised “Full RGB” power supply. Ever since Corsair’s first RGB product’s debut (except for their PSU lineup), they’ve been doing it well.

But now, it’s a different story with their CX-F RGB PSU series. They aim for the best gaming gear & hardware suited to last for a long time.

Corsair steps up their game each year, giving additional features that will benefit gamers. In terms of aesthetics, they always put all their effort into it, especially with RGB.

This is where the Corsair CX750F RGB 750W PSU comes in, providing 750 watts of power and 80 PLUS Bronze Efficiency. The Corsair CX750F RGB 750W PSU is their strongest CX-F series Power Supply.

To properly see the power of RGB with this power supply, make sure to select a decent case.

The Corsair CX750F RGB 750W PSU also comes in a white variant, which is our sample here. The white version suits white cases and this power supply is a good aesthetic choice if you have such a case.

Before we get started with all the features and specifications, let’s first head over to the packaging section of our Corsair CX750F RGB 750W PSU review.

Corsair CX750F RGB 750W PSU Packaging

The Corsair CX750F RGB 750W PSU has a neat package design, with a black & yellow theme. The product is displayed on the top and front side, with its logo on the upper-left portion of every side.

There’s quite a weight to it, so the electronic components must be high-grade too.

Inside, you get the usual user guide booklet, medium-sized black cable ties, and separate white cables (since this power supply is fully modular). Also included are the power cable, an A-RGB adapter, and the actual Power Supply Unit.

The Power Supply Unit is wrapped in a black foam, which protects it from any form of vibration. The power supply wires are wrapped in a ziplock plastic.

With that, shipping this product is completely safe. But in case you encounter problems, be sure to RMA your product immediately.

Corsair CX750F RGB 750W PSU Review – Design and Functionality

Let’s talk about Corsair CX750F RGB 750 PSU’s build design and how it powers up your computer components.

Let’s also discuss how well it functions with all its features.

The Corsair CX750F RGB 750W PSU, as indicated, provides 750w of total power to your computer. Most builds that have high-end components require lots of power, and this power supply will power up most of the high-end computers today.

For example, if you have an NVIDIA GeForce RTX 3080 Graphics Card and an Intel Core i9-10900K Processor, the Corsair CX750F RGB 750W PSU is sufficient enough to power up your build.

Since this is an 80 Plus Bronze power supply, its efficiency peaks at around 85% to 88%, depending on how much voltage there is in your outlet.

The cables are also detachable, which gives users an easier build experience. Not only will it look clean, but it will also lessen the hassle of chucking in any unnecessary wires on spots where there’s space.

If you’re looking to build a clean-looking PC, you should pick a fully modular power supply like the Corsair CX750F RGB 750W PSU. There’s also the RGB feature which shines on the fan chassis.

While black power supplies look good, we chose the white Corsair CX750F RGB 750W PSU, since it looks more decent in our opinion. It also shines much better than the black ones and looks aesthetically clean overall.

Cable Connections Supported

Let’s also not forget the cable connections supported within the power supply.

Here’s a list:



24-pin ATX Cable

4+4-pin 12V Cable2


6+2-pin 12V PCIe Cable2


SATA Power Cable



Molex Power Cable1


LED Cable1


Motherboard 5V Cable Adapter1


The Enjoyable RGB Lighting Experience

You can also control the RGB through the button behind or through your motherboard’s software and Corsair iCUE. Depending on the RGB connection you use, the software usage can vary.

Configuration through Corsair’s iCUE Software requires Corsair’s RGB Fan LED Hub, which can be sold separately. Once you have this, you can sync its RGB fan to your Corsair components.

To start syncing, simply connect the iCUE RGB Cable, and connect the other end to Corsair’s RGB Fan LED Hub. Then configure the lighting on Corsair’s iCUE Software.

If your motherboard supports RGB header, you can use the included A-RGB Adapter cable. This way, you can use your motherboard manufacturer’s software, and control the lighting from there.

Most RGB power supplies should look good if your computer case’s design has a transparent side panel and a see-through power supply shroud. Make sure to orient your power supply’s fan upwards.

For the best RGB experience, we recommend buying all Corsair products with RGB.

Now, let’s check out the key features of the Corsair CX750F RGB 750W PSU in the next section.

The cables are of high quality and have enough flex in them so that you can safely bend them around corners and route them through your computer case easily, without risk of damaging them.

The PSU is controlled via the Corsair iCue software which allows you to fully configure the RGB lighting. This means that you can finally have a PSU that matches the aesthetic style that you are going for with your gaming rig.

When the PC is running there is hardly any noise emitted from the PSU and even when under heavy load the noise is barely audible.
