Pure Power 9 500 CM Review: Testing |Specs | CPU Performance| Pros and Cons – It has been some time since the last test of a product from be quiet! but it is time to rectify the situation with today the very last power supply from the German brand, I named the Pure Power 9 in its semi modular version 500 Watts!

The power supply has the heavy task of succeeding the pure power L8 which was (and still is as long as there are on the market!) An excellent model combining quiet operation and very correct performance all for a price of the most reasonable. The Pure Power L9 series is available in 2 versions, one modular and one non-modular, only the latter is currently available and it is on it that today’s test will be carried out. On the program a power supply with a power of 500 Watts,
Offered at a price of around 85 € and accompanied by a 3-year warranty, let’s see what the beast has in its belly!

Sobriety is the order of the day, it looks like two drops of water like that of the pure power L8, a photo of the power supply in profile, the name of the model, the brand of course with the logo of the 80Plus Silver certification and the mention “cable management” which means that it is modular. On top of that be quiet! adds a small listing of the beast’s strengths, namely silence, high performance, multi-GPU support as well as the 3-year warranty.

At the back there is a table showing the distribution of the power, the dimensions of the beast as well as the length of all the cables and their number, at least there will be no surprises once the box is opened.

be_quiet_pure_power_9_500W_CM_box4

Inside the box we find the pure pure 9 wrapped in bubble plastic as well as of course the bundle!

be_quiet_pure_power_9_500W_CM_bundle

In addition to the power supply there are of course the modular cables, a power cord, the manual as well as the eternal screws and some plastic cable ties. The bundle therefore offers the minimum and this is quite sufficient for a power supply.

Here is the beast! At first glance almost identical to its little sister the modular L8, black paint very well done, a fan equipped with an orange border which is the color that the brand likes. The build quality is very good and nothing suggests that the pure power 9 is rather entry-level oriented.

be_quiet_pure_power_9_500W_CM_dessous

For quite some time now, be quiet! endows its power supplies with a bar-type grille rather than the eternal honeycomb, the look is more sympathetic and it does not change the air flow too much. Not much to say except that the border around the fan looks pretty good.

be_quiet_pure_power_9_500W_CM_dessus

As usual the underside (or what we will see once the pure power 9 installed in a box) is very sober, there is nothing 😉

be_quiet_pure_power_9_500W_CM_cote1

On one side the name of the brand is engraved in the metal, this looks pretty good but unfortunately this is not what we will see if the power supply is installed at the bottom of a box with the fan facing the low. Also note the presence of the warranty sticker, point of opening of the beast otherwise you can say goodbye to the warranty!

be_quiet_pure_power_9_500W_CM_cote2

On the visible side there is a large sticker with the required warnings as well as a power distribution table, we can see that the pure power 9 is equipped with 2 12V rails, like the L8 version.

be_quiet_pure_power_9_500W_CM_cote3

At the back the landscape is rather well known, in addition to the switch and the on / off button a honeycomb grid is present, it does not however cover the whole of this face, there is however enough space to breathe.

be_quiet_pure_power_9_500W_CM_cote4

The interesting part, the connectors for modular cables! On the left we can see the cables which are directly attached to the power supply, namely the 24-pin and the 4 + 4-pin processor, these 2 are anyway mandatory so there is not much to complain about. On the right there are 3 connectors for Sata and molex peripheral cables as well as 2 connectors for PCIe cables.

be_quiet_pure_power_9_500W_CM_interieur

be quiet! has as most of the time went to see FSP to manufacture its pure power 9, although the latter is very recent we are here in the presence of a derivative of the FSP Raider S, nothing too surprising that said given that it is also 80Plus Silver certified. The build quality is very good, the capacitors are mostly TEAPO and even if we are not up to what we can find on more high-end platforms they should still do the job well.

The pure power 9 fan is a 12 cm model rotating at a maximum of 1600 RPM, fortunately it should not reach this speed there 😉

The number of connectors and cables on the pure power 9500 CM are more than sufficient, of course the eternal 24-pin and 4 + 4-pin are present as well as 2 cables for the PCIe connectors, it could have had 1 single cable can power a graphics card but be quiet! has chosen to put 2. There can be several choices for this, either for a matter of heat release due to having 1 single cable, or to better distribute the 12V on the 2 rails, whatever However, it is always better to have 2 cables for a graphics card that consumes a lot, but unfortunately this will not help the cable management on the back of the motherboard. In addition to that we are entitled to a total of 6 x Sata, 3 x molex as well as the small FDD (which is really useless in 99% of cases),
The length of the cables is on the other hand a little tight for my taste, especially the PCIe cables with 50 cm which will force them to pass through the front of the motherboard and not the back in the rather bulky cases, 5 cm more n would not have been luxury.

The be quiet! Pure Power 9500 CM has a total of 480 Watts available on the 12V divided into 2 rails of 28A and 24A, enough to supply the vast majority of configurations on the market without the slightest problem. As I said, we are in the presence here of an 80Plus Silver certification, it does not run the streets and the manufacturers prefer to focus on Bronze or Gold, the efficiency goes from 87% to 20% load to 90% to 50 % load and 87% when the power is at maximum.
The ventilation is entrusted to a 12 cm fan of the brand capable of rotating at a maximum speed of 1600 RPM at its maximum.
The dimensions are rather classic with a length of 16 cm which should not pose the slightest problem in the vast majority of cases on the market, a pity however not to have made a more compact model which could be more suitable for a mini case. -ITX, but that’s not the main use for the little pure power 9!
Offered at a price of around € 85, the Pure Power 9 is the successor to the Pure Power 8 which has had great success on the consumer power supply market, let’s see what the tests give!

The consumption

Before we begin, let’s take a look at how the power supplies perform compared to the be quiet! Pure Power 9500 CM, in fact the various 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.

be_quiet_pure_power_9_500W_CM_resultats_consommation1

As we can see the consumption of the configuration with the be quiet! Pure Power 9500 CM is placed between the 80Plus Bronze certified power supplies and the 80Plus Gold, which is quite normal, with 80 Watts at rest and 352 Watts on load the difference with an 80Plus Gold power supply is very minimal.
Note that the consumption has been recorded at the outlet and for the complete configuration , in load for example and on the 352 Watts “drawn” at the outlet, the components only consume between 320 and 330 Watts of the 500 Watts available.

The tensions

be_quiet_pure_power_9_500W_CM_resultats_tensions1

Entry-level oriented power supply forces the voltages are of course not the most stable in the comparison, in fact the 3.3V goes from 3.33V at rest to 3.30V when charging, the 5V from 5.15V at rest to 5.22V when charging and the 12V meanwhile from 12.07 to 11.85V. The variation of 12V is not really the best but we remain largely in the nails of the ATX standard which allows up to 5% (therefore between 11.4V and 12.6V).

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.

be_quiet_pure_power_9_500W_CM_resultats_niveau_sonore

In terms of noise pollution there be quiet! should not be missed, as the brand plays on this point. Well here again the result is excellent, whether at rest or under load the noise generated by the power supply is inaudible, it will clearly not be the noisiest part of the configuration! I didn’t hear a single Coil Whine coming from the beast either, which could be a good point for those sensitive to this type of noise.
Note however that the power supply is not pushed to its limits so that could change with a graphics card consuming more (of the type R9 290 / 290X for example).

be_quiet_pure_power_9_500W_CM_random

Here we are at the end of this test, what can we say about be quiet! Pure Power 9500 CM?
be quiet! offers here a very well finished power supply, which will not show its entry level side and which has a look that will not be ashamed when installed in a windowed box. Semi-modularity will be welcome for those who want to have just the minimum number of cables installed in the tower, this will allow easier storage at the back of the motherboard. The performance of the Pure Power 9 is very correct, even if I would have liked a 12V which varies less in load, but we are not here in the presence of a high-end power supply.

The sound level is largely controlled with a power supply which is inaudible at rest and under load (with a configuration consuming around 300 Watts, which is representative of a good gamer config nowadays), a point that is close to the heart of the brand.

The only small thing that I could fault the Pure Power 9 is the length of the PCIe cables, indeed with 50 cm it will not be easy to go to the back of the motherboard to return to the graphics card, it will be necessary to often pass all this through the front and therefore have the cables visible, nothing serious though.
Offered at a price of around € for the semi-modular version 500 Watts la be quiet! Pure Power 9500 CM is a carefree replacement for the Pure Power L8, by being quieter and with higher efficiency and therefore lower consumption, it will be perfectly suited to a gaming configuration.
