Is There a Major Difference In Corsair RM vs RMX?

A major difference? Maybe not. However, there are a number of distinctions between the Corsair RM and RMX series. Let’s look into this one by one.

Corsair RM Is Cheaper

Perhaps the most evident difference between the two power supply units is that Corsair RMX is more expensive.

However, manufacturers do have a valid explanation for this. After all, they have equipped the newer PSU with considerable improvements and additional features.

Corsair RMX Is Equipped With Better Quality Capacitors

Customers already know that when it comes to the quality of installed capacitors, Corsair RM is of no match to RMX. Low-quality capacitors were installed in the RM series to make it more affordable for buyers on a tight budget.

Quality of Cooling Fans

Although their quality still remains a topic of debate between Corsair users, it is obvious that RM hosts more affordable cooling fans as compared to RMX.

Corsair RMX is equipped with high-end Japanese Nichicon and NR135L fans whereas RM hosts Hong-Hua fan and Chinese Elite caps.

RM Models Support Modern Standby Mode

One advantage that RM users enjoy is that it comes with Standby Mode in Windows 10 which ensures your PC turns on quickly instead of taking ages to come to action.

Observations have shown that PCs with RM PSU take only about 5 seconds to turn on from S3 sleep mode.

RMX Models Contain In-Cable Caps

RMX models are equipped with in-cable caps. These help to fight against ripple suppression (or so the customers thought!).

Later on, the manufacturers at Corsair pointed out the PSU’s performance was not much different with or without this technology and so did not feel the need to continue using it for other series.

These were some basic differences that we came across when reviewing Corsair RM vs RMX power supply units. Is it still not enough to draw the final choice?

Then let us look into the two products individually and examine their most distinctive features, pros, and cons to see which one is more suitable for you.

2. Corsair RMX Fully Modular Power Supply

Specs

Brand: Corsair | Model Number: CP-9020179-NA | Product Weight: 3.65 pounds | Product Dimensions: 6.3 x 5.91 x 3.39 inches | Color: 80PLUS Gold | Size: 750 Watt |

Review of Corsair Corsair RMX

This series was launched in 2015 as an alternative to the RM series for customers who were not willing to compromise on the quality of the capacitors. Moreover, the manufacturers were keen to introduce some other improvements as well.

There were a number of features that were retained in the RMX series. These included the zero RMP mode to enable the noise-free operation and 135 mm rifle bearing as well. Now let’s have a look at features that were enhanced in order to make the RMX series more desirable.

The first change was to install up-to-date capacitors. Corsair RMX series was equipped with 105-degrees capacitors that can perform well at high temperatures.

Therefore, it was deemed safer to use without the fear of malfunction. This was reflected in the warranty time that Corsair promised for this series. Customers can enjoy swooping 7 years of completely guaranteed use.

Furthermore, as we mentioned in the pros of Corsair RMX, it came with a more extensive power line. You can choose from low wattage of 550 W, 650 W, 750 W, 850 W, and 1000 W.

Another difference is that RMX has Type 4 cables which means it carries additional 4 pins and capacitors. This was an evident improvement over the Type 3 cable structure of Corsair RM750. It helped regulate the voltage and keep the load of the power supply unit under check.

The last thing Corsair manufacturers had to take care of was how troubles customers felt when using bulky dongles and inefficient Link software. What could the possible solution be? Remove the software altogether!

As you can see, Corsair RMX undoubtedly came with multiple enhancements. However, it also carried a pricey tag so users really had to be smart when choosing between the features they need and deciding how much they should be spending on it.

• RMX series have more advanced protective features as compared with its previous competitor.

• Some of the improvements that were installed to ensure a safer user experience included Over current protection, over-voltage protection, under-voltage protection, short circuit protection, and over-temperature protection.

• Over-current protection shuts off the power supply unit when there is a current overload.

• Over/under voltage protection keeps the voltage of the device under control and it quickly turns off the power if any rapid fluctuation takes place.

• Short circuit protection, as the name implies, is the feature that comes into place to save the gadget in case a short circuit happens.

• The last protective feature i.e. over-temperature protection shuts off the rail in case the temperature rises too much.

• Next, RMX is made of Type 4 cables with additional 6-pin cables for SATA use and peripheral power.

• Similar to the RM series, this model also allowed for minimal noise pollution while in operation. This was made possible by installing a smart fan controller that only begins when the PSU reaches a specific value.

• RMX model has a 160 mm casing. Since the size is an important factor to consider when most customers are making the purchase, this model gets extra points because it fits into all modern PCs.

• Japanese capacitors proved to be more reliable than Chinese counterparts that were installed in RM Corsair models.

Take-Home Message – Corsair RM vs RMX

After going through the review, we can safely conclude that one of the most basic differences between Corsair RM vs RMX is their cost. Corsair RMX, being the latest version, is a bit expensive as it carries minor other improvements as well.

However, the good news for customers with a tight budget is that Corsair RM is equally competent and reliable for long-term use. It is equipped with all the features that one expects from a good power supply unit so you don’t have to feel sad about sticking to an older product.
