Seasonic M12 II 620 Evo: Review | Specs | CPU | Hashrate| Setup

Seasonic M12 II 620 Evo: Review | Specs | CPU Performance | Hashrate| Setup | Pros & Cons| Test – Here I am back at Seasonic after testing the latest revision of the Seasonic S12 II 520 (here) with its big sister, the M12 II 620! On the program, a 620 Watts power supply equipped with 80Plus Bronze certification, new “FDB” fan as well as full modularity.
I have already had in my hands an older revision of the M12 II (test here) and the only downside I could find was a rather aggressive ventilation management and therefore noise pollution in charge (with a conventional configuration consuming a little over 300 Watts) a little high. If Seasonic did its job well as I saw in my last review of the S12 II then it might turn out to be a little more interesting.

8.1 Where to find the Seasonic M12 II 620?

8.2 Related posts:

Offered at around € 100, it is around € 10 more expensive than its little sister, it shares exactly the same platform but you only pay a little extra for modularity, something to interest those for whom space is limited!

The box is rather sober, as usual with Seasonic, there is essential information such as the model, the power, the 80Plus Bronze logo but also a small mention of the presence of Japanese capacitors capable of handling 105 °, generally absent in entry-level power supplies. However, marketing has struck lightly here with this little phrase “The Ultimate Fully Modular Power Supply”, ultimate fully modular power supply? What about the “P” and Snow Silent versions from the same brand then? 😉

At the back we find a listing of the main points of the beast, namely Japanese 105 ° capacitors, intelligent ventilation control, multi GPU support, a 5-year warranty as well as the advantage of having a fan. “FDB” instead of the old ball bearing.

On the sides we find the power distribution table, the number of connectors available, a listing of protections, dimensions, etc.

Inside we find the manual placed on the foam containing the power supply, the modular cables are on the right in a bag provided for this purpose. The packaging is identical to all Seasonic products, the foam perfectly protects the power supply unit.

The bundle is made up of:

1 x Seasonic M12 II 620 power supply unit
1 x power cord
1 x Seasonic sticker
1 x manual
4 x screws

A bundle reduced to the minimum vital here, apart from the sticker which will be used to show everyone that the PC is powered by a Seasonic power supply!

Here is the beast! It is clear that nothing here is made for the flashy, the S12 II is all black with a honeycomb-shaped grille above the fan. Unlike the S12 II it is a little deeper, you have to fit the PCB of the modular connectors, however, we only go from 14 to 16 cm, which remains reasonable.

Everything is done in the respect of sobriety here, carcass painted in black, black fan, honeycomb grille and even the black warranty sticker! The build quality is there, no doubts about it even if this is not a high-end model.

Nothing extraordinary on the underside, it’s black, desperately empty, one thing is certain, the sobriety is there!

On one side we find the M12 II Bronze logo on a black background and on the other a power distribution sticker.

Completely modular as I said at the beginning of this article, everything is well indicated and there will be no risk of making a mistake by plugging something in the wrong place. We can easily recognize the Seasonic leg, all the brand’s totally modular power supplies look like this!

At the back there is a honeycomb grid, a small 0/1 button and a small Seasonic sticker showing that the power supply is compatible from 100 to 240VAC.

The design now known and recognized, a Seasonic S12 II base to which has been added a PCB and modular connectors, the same design that has been taken up by many different brands (Corsair, XFX and so on), Japanese capacitors from quality and excellent workmanship.

And here is the big change of the last revision, the “FDB” bearing fan, supposed to be quieter than the old ball bearing while keeping an excellent lifespan, well this is the same one as we find on the Snow Silent (but which is in white), the HA1225M12F-Z from Ong Hua running at a maximum speed of 2050 RPM for a given consumption of 5.4 Watts.

The number of connectors on the Seasonic M12 II 620 is more than enough, the eternal 24-pin and 4 + 4-pin CPU as well as 4 6 + 2-pin connectors divided into 2 cables, 8 x Sata, 5 x Molex and a small molex adapter -> floppy drive for those who still need this. It goes without saying that it will be possible to feed a large configuration, more than what 99% of users will ever need!
The cable length is also largely sufficient even for the largest towers, especially for the 4 + 4-pin with its 65 cm.
Note that apart from the 24-pin the cables are not sheathed but the wires are glued to each other to end up with flat cables, we like it or not.

The Seasonic M12 II 620 has 576 Watts on the + 12V, divided into 2 rails of 24A each, enough to power a good big configuration, too bad it does not however have the 620 Watts for which it is sold in full on the 12V, but this is the case for almost all power supplies equipped with the 80Plus Bronze certification on the market. This certification ensures a minimum efficiency of 85% (European standards) at 20% load, which will ensure a release of heat and therefore a cooling requirement contained.
The ventilation is entrusted to an “FDB” fan from Ong Hua, the same as in all recent Seasonic power supplies (Snow Silent 750, S12 II etc ..) which should be particularly silent (as long as it is not running. thoroughly of course!).
The dimensions as I said above are more important than its little sister the S12 II, in fact we gain 2 cm in length to go from 14 to 16 cm, it is not huge but it could be prohibitive in some small boxes , especially mini-ITX.
Regarding the price it turns around 100 €, which is not cheap but not excessive either, we must not forget that we are present with a power supply equipped with Japanese capacitors and modularity total, it will also be able to supply almost all the configurations of the market, even the largest gamer configs.

The consumption

Before starting, let’s take a look at the performance of the power supplies compared to the Seasonic M12 II 620, 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.

As we can see the performance of the Seasonic M12 II 620 is clearly not bad, even very far from it! In the same way as its little sister the S12 II, it almost tickles the 80Plus Gold power supplies under load with its 355 Watts as well as at rest with 78 Watts, it goes without saying that these results are very good for a power supply that has “Only” 80Plus Bronze certification. As usual, the power supply is not pushed to its limits with the test configuration, but it represents what is done in a high-end configuration designed for games nowadays, so what 99% of users are likely to pull at the socket.
Note that the consumption was recorded when taking and forcomplete configuration , under load for example and on the 355 Watts “drawn” from the outlet, the components only consume between 320 and 330 Watts of the 620 Watts available.

The tensions

Same platform, same observation, the M12 II 620 turns out to be stable but of course not at the level of its big high-end sisters, the 12V goes from 12.05V at rest to 11.94V under load, the 5V from 5.05V to 5.07V and the 3.3V from 3.32V to 3.34V. For the moment the M12 II 620 does not disappoint, just like its little sister the S12 II, it only remains to see if the nuisances are up to the task, but with the new “FDB” fan this should in no case. be a problem just like all models that are equipped with it!

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.

Seasonic_M12_II_620_results_noisances_sonores

The fan is indeed much quieter than what we saw in my test of the old version of the M12 II, with 32 dB at rest for 34 dB under load, it is clear that this is not the case. power supply which will be the problem when the configuration is used! Like the S12 II 520 tested recently, the fan emits a very slight rolling noise once the ear is really glued to it, but disappears as soon as you are more than 15 cm away, so nothing that could not be source of inconvenience.
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).

Here we are at the end of this test, what to say about the Seasonic M12 II 620?
After the test of the M12 II 520 at the beginning of the year which was not lacking in assets, there was however a small point to review from these gentlemen from Seasonic, namely an aggressive ventilation which rose very quickly in the turns. The latest revision equips the beast with the “FDB” bearing fan which now equips a large part of the brand’s power supplies and therefore allows a much lower sound level than before (at least at the same load), which is very clearly a good point for those who want a minimum of silence.

However, it incorporates all the good points of the old revision, namely very good manufacturing quality, total modularity, a known and recognized platform as well as very good quality components and an 80Plus Bronze certification ensuring performance and clearance of very contained heat.
Offered at a price of around 100 € the Seasonic M12 II 620 is not cheap but seeing the services it offers it will be perfect for those looking for a reliable power supply for their gamer config, we unfortunately have nothing without nothing!
