RGB for the Toughpower DPS G RGB series power supply, but the result was not as impressive as expected because the lighting was quite poor and difficult to “integrate” with the light show of the system.

Recently, AeroCool introduced Aerocool Lux RGB source models with… integrated RGB LEDs next to it. This design is somewhat too simple, can not show off the beauty of the LED and even this LED can not “catch color” with the PC system in general.

With that in mind, Corsair, one of the leading manufacturers of PC components from the US, has launched an all-new CX-F RGB series power supply unit, bringing in its ambitions to dominate the kit market. ATX sources have controllable RGB LEDs on the market today.

Therefore, users must use a chassis with high ventilation capacity to ensure that there is always cool air to cool the components inside the power supply.

This detail shows that the Corsair engineers are not … “lazy” that just integrating a cooling fan into a common position on the power supply is done, but the company engineers have separated the lamp circuit and the fan circuit. compared with conventional wired fans.

This design on the Corsair CX550F RGB is absolutely essential to being able to show off your RGB LED-equipped heatsink.

Due to the shell’s design Corsair CX550F RGB It is quite sturdy and very difficult to remove, so the writer has not had the opportunity to open up to see the layout of the internal components, but through careful observation, it can be seen that the radiator fan of the power supply is probably a customized version. variable of Corsair SP120 Pro 120mm with acceleration to 1400rpm with 8 high quality RGB LEDs.

According to some sources, the “conscience” part of the Corsair CX-F series power supplies released during this batch is outsourced by HEC.

Gentle testing with systems including microprocessor Intel Core i7 8700 and Gigabyte RX 5500 XT Gaming OC 8G graphics card, the power supply is still capable of working well for many hours of continuous Horizon Zero Dawn PC playing.

The LED system on the power supply works quite impressively with high brightness, thanks to its familiar 8-bulb structure. However, due to the unique design, you must choose cases with “hole punching” for the power supply instead of “confined” into a separate area as with most cases on the market today.

General, Corsair CX550F RGB is a power supply with a solid design, possessing an impressive RGB LED heatsink but still capable of stable operation with “heavy” components for a long time, can satisfy the love demand from the “hardcore” fans of the “light-color-flash” chassis show that is very popular in the market today.


Must say Corsair CX550F RGB is a product brought by Corsair to a radical “transformation” compared to the CX series power supply version available on the market from 2017 onwards.

The company has brought a new, sturdier, much stronger design, with the heatsink lights and controllable 8-ball RGB LEDs through the iCUE program, becoming the first power supply line of Corsair in the mid-range segment becomes “smarter” besides the previous line of products RXi, AXi and HXi.
