Corsair returns to the load with a new power supply model, after the RM in version “i” (for the functionalities linked to Corsair Link technology) of which I was able to test the 750 Watts version here we are entitled today to the “x” version. On the program we find the same strengths as the RMi, 100% Japanese capacitors, operation at 50 ° ambient, hybrid operation of the fan (off when idle and up to a certain consumption), 100% modular, 80Plus Gold certification, etc. In the end the only visible differences are the fan which goes from a 13.5 cm FDB to a 13.5 cm with a “rifled bearing” and the lack of compatibility with the Corsair Link software.
The RMi are excellent power supplies and there is no doubt that the RMx will follow the same path, but this will have to be seen during testing!
Regarding the price, we are 20 € less than the RMi at equal power, therefore between 109 € and 179 € for models from 550 to 1000 Watts, all with a guarantee that inspires confidence of 7 years.

Corsair_RM550X_boite1

The box changes from white for the RMi to black for the RMx, there is a photo of the product on the front with the model, the power available, the 7-year warranty, the 80Plus Gold certification as well as a small list of strengths of the beast. Marketing is not very present here and that’s a good thing!

Corsair_RM550X_boite2

At the rear are graphs representing the performance as well as the sound level depending on the load, we can see that the RM550x will be in fanless mode up to around 225 Watts. Also present a table of the power distribution, the 12V alone delivers the full power for which the power supply is sold, namely 550 Watts (well 549.6 Watts but let’s not quibble!).

Corsair_RM550X_boite3

On the side, a listing of all the available connectors, we notice that the 550 Watts version only has 2 PCIe 6 + 2-pin connectors which will allow you to connect a single graphics card, quite honestly this will be enough for 99% of users. The number of Sata connectors is also very sufficient with the possibility of connecting 6 peripherals, as well as 4 peripherals powered by Molex.

At the opening of the box we find the manual placed on a cardboard mold (egg packaging type!), On the right the bag of modular cables and the power cord.

Corsair_RM550X_bundle

The bundle consists of:

  • 1 Corsair RM550x power supply
  • 4 fixing screws
  • 1 sticker Corsair
  • A handful of cable ties
  • 1 power cord
  • Modular cables
  • Manuals
  • 1 warranty leaflet

Corsair therefore offers a complete bundle, with everything you need to plug in the beast, no frills here, it is a power supply after all 😉

Corsair_RM550X

Here is the beast! All dressed in black and covered with stickers. The paint, the general finish and the materials are very good and there is no doubt that we are facing the high end here. Let’s take a closer look at all of this.

Corsair_RM550X_below

The RM550x is a true copy of what we find on the RMi, namely a grille made of bars and not honeycomb under which we find the fan with gray blades. The quality is like its big sister, namely excellent.

Corsair_RM550X_above

Below is a sticker indicating the make, model, the various checks carried out as well as obviously a power distribution table, this can always be used!

Corsair_RM550X_cote1
Corsair_RM550X_cote2

The two sides are identical with the presence of a good big sticker recalling the brand and the model, we would not want the power supply to pass for another model! Note that regardless of the direction of connection, the sticker will be in the right direction.

Corsair_RM550X_cote3

A very classic rear end with a honeycomb grid covering almost all of the space, it is clear that the heat dissipation will be done without the slightest problem. Ah yes, a small label reminding the model, you never know, in case you haven’t seen it on the sides (or below!).

Corsair_RM550X_warning

Note that on this part there is a sticker explaining that the power supply works in hybrid mode, that is to say that at rest the fan will not turn and therefore do not worry!

Corsair_RM550X_cote4

The interesting part, modular connectors! As we can see there is not as much here as the 750 Watts version of the RMi that I tested previously, normal with a 550 Watts model! However, there is everything you need to connect a PC, even a fairly loaded one, 1 PCIe connector, 1 CPU connector, 2 connectors for the 24-pin as well as 3 for Sata and Molex peripherals, it may seem a little empty. but don’t be fooled!

Corsair_RM550X_interieur

Corsair continues the adventure of RMx models with CWT here, the build quality is very good and all the capacitors are Japanese. The design is identical to the 650 Watts model of the RMi.

Corsair_RM550X_interieur_ventilateur

The fan is therefore a Corsair NR135L, 135 mm with a maximum consumption of 2.64 Watts.

Molex + Molex + Molex + Molex45 + 15 + 15 + 15 cm
Molex -> FDD10 cm

The number of connectors of the RM550x is largely sufficient for almost the majority of mono-GPU configurations on the market, in addition to the eternal 24-pin connectors, 4 + 4-pin CPU and the 2 PCIe 6 + 2-pin connectors there are also 3 cables responsible for supplying a total of 6 Sata peripherals and 4 Molex peripherals. A small adapter is also present and will allow you to connect a floppy drive (who still has that?) Or any other device using a connection of this type.
All the cables will be able to adapt to a large tower without problems, 61cm for the 24-pin, 65cm for the 4 + 4-pin as well as 60 + 15cm for the PCIe, there will be no problem to connect all the components .
Note that the 24-pin, 4 + 4-pin and PCIe cables are not flat but round and sheathed, each to its preference according to the tastes and I personally prefer this type of cables but it would have been more homogeneous to deliver all the cables. round cables for once, or all flat! In short, this does not change the quality of these in any way, but I find it a bit strange 🙂

The Corsair RM550x does not lie about the power delivered with a single 12V rail capable of supplying all of the 550 Watts for which it is sold, the 3.3V and 5V combined are capable of delivering 130 Watts, which is to say that this will suffice for 99% of “gamer” configurations on the market, no offense to these gentlemen who would make everyone buy 750 Watts!
80Plus Gold certification as I said with a maximum efficiency of 92% at 50% load, this will clearly help the power supply to release the minimum heat and therefore the need for cooling will also be less, which is always good for the nuisances sound. Speaking of the need for cooling, it will be provided by a brand NR135L, 135mm equipped with a “rifled bearing” specially designed to have a long life and a lower noise level than ball bearing fans.
The dimensions are fairly standard although it is not a very small size with 16 cm in length by 15 cm in width and 8.6 cm in height, it should logically not pose the slightest problem in an ATX case, to see in a mini ITX box however. In terms of weight, we are average for this type of product with 1.66kg, nothing out of the ordinary.
Offered at a price of around € 110, it can be really interesting because Corsair has provided it with a 7-year warranty as well as 100% Japanese capacitors and an MTBF of 100,000 hours but given for 50 ° (which ‘is very clearly not the case with everyone, being satisfied with 40 °, or even 25 °).

The test platform

The Corsair RM550x power supply has been tested on the configuration below:

  • Processor : Intel Core i7 875K @ 3.2 Ghz
  • Motherboard : Asus P7P55D

The consumption

Before starting, let’s take a look at the performance of the power supplies compared to the Corsair RM550x, indeed the different 80Plus certifications will directly influence consumption, so this will be a good way to have concrete results. Only the S12 600 (this did not yet exist at the time of purchase (but the following versions of this power supply had the classic 80Plus certification, so 80% / 80% / 80% at respectively 20% / 50% / 100% of load)) and FSP Hyper M 500 do not have 80Plus certification.

Corsair_RM550X_resultats_consumption

The consumption of the RM550x is really excellent, at rest and with 75 Watts we are at the same in the lower part of the 80Plus Gold in the comparison, at the same level as the 80Plus Platinum so as much to say that it is at all good. In load and with 346 Watts once again the RM550x does not do in half measure with quite simply the best result obtained on par with the Seasonic X650 KM3, at a small Watt of the Platinum power supplies of the comparison, there is really nothing to say about the news from Corsair.
Note that the consumption was noted at the outlet and for the complete configuration , in load for example and on the 351 Watts “drawn” at the outlet the components only consume approximately 324 Watts of the 550 Watts available.

The tensions

Corsair_RM550X_resultats_tensions

No worries about voltage stability, the Corsair RM550x holds everything without flinching with a 3.3V which goes from 3.34V to 3.36V, the 5V from 5.05V to 5.07V and the 12V from 12.17V to 12.19V, as much to say that the beast is very stable, without arriving at the level of stability of the more high-end power supplies of the comparison (but the prices are of course not the same!).

For the moment, we are very good with the Corsair in today’s test, but the real sinews of war are in the level of noise pollution, indeed who would like a low-consuming power supply with excellent voltages but who is breaking your ears? Corsair sells the silent operation of its RMx power supplies, hybrid ventilation, components chosen to have as little Coil Whine as possible, let’s see what that gives!

Noise pollution

Warning: Part to be taken with a grain of salt, unfortunately not having access to the appropriate equipment and using an android application to take the readings the measurements below are only indicative! The readings were taken 15cm from the feed.

Corsair_RM550X_resultats_nuisances_sonores

When the ventilator of the RM750i did not start in load that of the RM550x on the other hand starts up instantaneously, the ventilator is thus very clearly related to the consumption of the animal and not the internal temperature. Of course, when idle, the power supply is inaudible because the fan is not running, and there is no “Coil Whine” to report, under load the fan has not exceeded 32 dB, which is an excellent result and will not be heard in a box, largely muffled by the noise of the smallest fan (CPU cooler, graphics card, box etc.)!

Corsair_RM550X_random

Here we are at the end of this test, what to say about the Corsair RM550x? The price drops by 20 € compared to its big sister the RMi on models from 650 to 1000 Watts, the 550 Watts tested is only available on the RMx and it will cost around 110 € to get it. In the end and seeing the benefits there is no doubt that it will be perfect for a high-end gamer config!

Based on the excellent RMi Corsair series could not really go wrong with the RMx, in fact we keep the strengths of the big sister, excellent build quality, 100% Japanese 105 ° capacitors, 80Plus Gold certification, hybrid operating fan , operation up to 50 °, exemplary stability and strict silence. The only thing that changes is the lack of Corsair Link compatibility, which quite frankly between us is nothing more than a gadget, especially for a power supply!

Advantages

  • Silence
  • Stability
  • Build quality
  • 100% Japanese 105 ° capacitors
  • 7 year warranty

A big thank you to Corsair who allowed me to do this test.
