The CX550F is among the many finest mid-level PSUs that includes RGB lighting. Corsair teamed with HEC for its CX-F line, and it used a contemporary platform together with a high quality fan with superior RGB lighting, that means that the manufacturing prices elevated; therefore, the CX550F prices greater than the class’s common. Nonetheless, in addition to the eye-candy options, the unit additionally affords good efficiency and isn’t noisy below regular working circumstances.
For those who do not care a lot in regards to the RGB lighting, which is the principle motive to spend extra and purchase the CX550F, you can even take a look at the Corsair CX550M and the XPG Pylon 550. Each use much less superior platforms than the CX550F but nonetheless supply greater general efficiency. If we had an RGB class in our best PSUs article for mid-level items, the CX550F might be included.
The Corsair CX550F is the bottom capability member of the corresponding line, which has three members. All of them function RGB lighting and are primarily based on a contemporary HEC platform. Furthermore, they arrive in two colours, black and white, and all their cables are modular. The CX550F is rated Bronze within the 80 PLUS commonplace and Gold by Cybenetics. It additionally has a noise score of Cybenetics-Normal++ (30-35 dB[A] common noise output). Often, this unit goes for $90, so it is not precisely inexpensive. Nonetheless, in the course of the overview, Corsair supplied it at a lower cost of $65.
Corsair despatched us a white unit that appears nice with the identical colour modular cables and the RGB lighting results of the fan. The RGB lighting may be managed by the non-obligatory Corsair iCUE RGB lighting controller or a appropriate mainboard by the included 5V ARGB adapter. For those who do not need to purchase the Corsair controller and your mainboard does not help RGB management/sync, you may customise the PSU’s lighting through a push-button on the entrance.
To cycle by lighting modes, you will need to press and maintain the button talked about above for about three seconds. If the present mode is not rainbow, you press the button shortly to cycle by colours. You must also do not forget that the push-button will not work if the PSU is in software program management mode, related to the Corsair controller or the mainboard.
The out there lighting modes are: rainbow wave, rainbow, rainbow breathe, rainbow blink, sequential, strong, single blink, and pulse. You even have the choice to disable the fan’s lighting.

The PSU’s low capability does not enable for multiple EPS and two PCIe connectors, with the final put in on the identical cable. Nonetheless, the variety of peripheral connectors is enough.
All cables are lengthy sufficient, however as ordinary, we want to see longer distances between the peripheral connectors. Nonetheless, the dearth of in-cable caps is sweet information for many customers Additionally it is good to see thicker 16AWG gauges as much as the primary PCIe connector for decrease voltage drops for the reason that identical gauges need to deal with a pair of those connectors.

Corsair helped HEC construct this platform, which is superior for a merely Bronze unit within the 80 PLUS scheme. The CX550F manages to be slightly above the bottom Gold effectivity threshold within the Cybenetics scale, incomes the corresponding effectivity certification. As an alternative of the everyday double-forward topology we often discover on this class, HEC used a half-bridge topology and an LLC resonant converter for elevated effectivity. Furthermore, we see a synchronous design and a pair of DC-DC converters for the minor rails on the secondary facet.
The EMI filtering stage contains all vital elements, so we anticipate low EMI emissions. There may be additionally a discharge IC to limit power losses on the bleeding resistors. Furthermore, there’s a MOV for voltage surges and an NTC thermistor for decrease inrush currents. The latter just isn’t supported by a bypass relay, which is a bummer.
The one bridge rectifier can deal with as much as 10 Amperes.
The APFC converter makes use of two Infineon FETs and a single increase diode offered by the CREE. The majority cap is by Hitachi, which offered its capacitor enterprise to a Chinese language model.
The APFC controller is a Champion CM6500 IC. One other Champion IC, the CM03X, is used to limit vampire energy by reducing off the APFC converter throughout standby.
The primary FETs are organized in a half-bridge topology, whereas an LLC resonant converter boosts effectivity. It’s managed by an MPS HR1001C (opens in new tab) IC.
The FETs that regulate the +12V rail are on the solder facet of the principle PCB. 4 Nexperia FETs are utilized in whole. The minor rails are generated by eight FETs and use an Anpec PWM controller.
The electrolytic filtering caps on the secondary facet are principally offered by Teapo, and belong to the SC line. A lot of polymer caps are additionally used for ripple filtering functions.
The 5VSB circuit makes use of a single SBR on its secondary facet. The PWM controller is a Energy Integrations TNY290PG IC.
A number of polymer caps are put in on the modular board.
The supervisor IC is a Weltrend WT7527, supporting all important safety options however OTP (Over Temperature Safety).
Soldering high quality is sweet
The cooling fan makes use of a rifle bearing, so it is going to final a very long time. Its RGB lighting can also be of fine high quality.
