-----------------------------------------------------------------
The new Corsair RM series, the 2019 is not actually in the name, so that mix-ups are actually pre-programmed, rely on completely new techniques to make the power supplies fit for the upcoming updates of the ATX specification. The new specification recommends 70% efficiency at 2% load, which currently only very few power supplies can do. But the RM 2019 can do it and even more!

i wish this is in english! good stuff there
Thanks, We Added English subtitles.
Spannendes Netzteil. Bin gespannt wie andere das mit der hohen Effizienz bei niedrigen Lasten lösen werden.
Also, I read your review on the RM650.750 and 850. At the end of the review you stated that you and corsair were in contacts to further investigate the problems with the 650 version. Did you get new samples? were the problems ever fixed? hope to hear from you, I am planning to get a RM650 :)
The first versions also had start problems, which Corasir wanted to fix. The problem was more severe with rm650 than with the larger ones.
I have to talk to some colleagues and see how the last status of Corsair is, the latter might take a while because the employee is sick
@@tweakpc Thank you very much for your hard work! Me and a lot of people really appreciate what you guys are doing. I was going to choose between the Corsair RM650 (2019) and the new Seasonic GX-650. Which one would you recommend? Also, will you guys be doing a review on the new GX-650? I can't find any reviews on the internet at all, it's crazy to think a famous PSU series still has not been reviewed hehe. I think it is safe to assume that they have fixed the issue with the older version (Seasonic Focus Plus) randomly turning off/blackscreen due to problems with compatibility between certains GPUs, namely the GTX 970 and Vega 56/64 GPUs.
@@Woopdeedew Thanks.
Both have their advantages and disadvantages. Do you mean the Focus GX or the Prime GX? Some we haven't had yet, I have to see which are more interesting to review.
I don't think you're doing anything wrong with either of them.
If you are concerned then take the RM
@@tweakpc Oops, my bad should have been more specific hehe, I meant the Seasonic Focus GX-650 Gold. Yeah, supposedly, the new GX,PX and GM line up are a "fixed" version of the old Seasonic Focus Plus series. problem is, I can't find a review anywhere. Thank you so much for replying to my comments.
@@Woopdeedew Not your fault, the new name is irritating. Yes, we had one here, I have to look, because Robert did it for a print magazine. Apparently they fixed the shutdown problem, but these peaks are now affecting Ripple.
But I still have to look.
If you use the affected graphics cards then an RM Corsair would be the choice.
Alternatively check out the Tt GF1, I found it surprisingly well done
hey hello maybe you could help me figure out something. whether such a phenomenon is normal. I have a corsair rm 650 2021 version and I am wondering about the operation of the fan. My point is that when it turns on a benchmark that causes a high load on it, enough for the fan to turn on. even if I turn it off immediately after the fan starts, it will run for at least 15 minutes despite the fact that the load will not be anymore. is it normal in these power supplies that this fan, when it turns on, has a certain time of operation, despite the fact that the load is no longer there. because when I load it for 15 minutes and turn off the load then it stops after a while. and when I cause a temporary load then it will also rotate 15 minutes. is something like this normal? or is it a defect
It,s normal the Fan is Temperature and load Controlled
@@tweakpc thanks for the answer . but in the case that I gave there is no temperature or load, so why does the fan spin for 15 minutes. is it some kind of waiting by the power supply after it temporarily got a high load? is it done so that it won't turn on and off too often?
@@zgl7248 When you load the power supply, the temperatures in the power supply increase. The rest of the hardware also generates waste heat. Therefore, the PSU does not immediately switch off the fan when the CPU/GPU load drops, but with a delay.
@@tweakpc but including, for example, the furmark test for the processor and gpu for 5 seconds it will not generate any higher temperature and the fan spins 15 minutes anyway and only a temporary high load which is not so high at all because my whole system 100 loaded with a maximum load of 350W. and the second thing was that I tested the power supply outside the pc case. So due to the temperature, it's not for sure.When testing power supplies, did you meet and think that such a long passive state is normal? because as for me it looks like programmed because always looking at the time it comes out exactly the same
@@zgl7248 sure there may also be a timing element. This is a feature so the fan will not constantly switch on off if the load changes often. Some units have this, especially newer corsair that have digital controlled fans. I have not yet testet the rm 2021, only rmx 2021.
So, the PWM change that increases ripple only happens when you have very low load right? if you are not using low load it will stay on LLC resonant and will only change to burst mode if the PSU is using low load? I
no not exactly, the problem is not at low load but at the threshold of the operating mode when switching from low load to normal operation.
So there was actually only a problem if you were unlucky, because to operate a PC exactly at this threshold
@@tweakpc If I solder fan to 12v rail , will I dodge this issue? How pwm signals get effected by that ? It will only behave via temps?
Hello. Which one is better. Corsair RM750 or FSP Hydro G Pro 750? Both are guaranteed for 10 years.I guess there is no uvp in fsp and the fan size is smaller.but they say better as pcb. Eco mode key is available in fsp. I am curious about your comment.
I don't know the FSP, but they are usually not that quiet and I checked and some tests say that the RM are quieter
@@tweakpc Thank you. You are right. RM is better at silence.
Does it have good efficiency if my total system powers is needing 550 Watt?
You can see full efficiency tests in our review here in the charts:

@@tweakpc thanks!
Thank you for the very informative video. Should I be worried for buying the RM750 (Chinese capacitors) instead of the RM750x (Japanese ones) for my Ryzen 3950x, single video card build? I regret about not reading more before making the decision. Are Japanese capacitors that much more reliable? I don't plan to overclock but am worried after finding out there are Tier PSU lists. @TweakPC thank you!
No, not really, firstly Corsair gives a guarantee and secondly the Japanese capacitor subject is highly exaggerated.
The simple Japanese capacitors are also made in China. If you want to have really good Japanese capacitors you have to pay much more, I would say that in the lower price segment it can even happen that Taiwanese & Chinese capacitors are better.
Don't let the topic drive you crazy
@@tweakpc so in short the subject which capacitor is made from either from china or japan doesn't actually matter? I actually bought the RM650 it came today, it's still pretty good for a Ryzen 5 3600? Might overclock soon but for now It'll be running stock.
Was für Schutzschaltungen hat das Netzteil eigentlich
hallo ich habe das RM650 seit gestern verbaut und wenn ich den pc ausschalte hört man vom Netzteil ein surren, erst wenn ich den schalter auf 0 stelle wirds ruhig. Ist das Netzteil defekt?
Ist schwer zu sagen aus der Entfernung, ein leichtes surren kann normal sein, aber auch auf einen Defekt hinweisen.
Du solltest ggf corsair Anschreiben was die dazu sagen. Vg Thomas
Nope das scheint normal zu sein, denn bei mir ist es auch so :)
The fan should start at about 40% load (260W)?
The fan control is not only load but also temperature controlled. in newer reviews you will find several curves for different cases.
wäre fast ne überlegung wert
Überlegung für was ? :)
Kauf dir lieber ein Straight power e11 von be quiet
@@tweakpc als Netzteil für mein kleines 3way SLI
@@Olafapfel is mir der aufpreis absolut nicht Wert
Aktuell kosten die noch etwa gleich viel, aber mal sehen wie sich das entwickelt. Vom Straight Power soll ja auch ein Update kommen. Ich denke daher die Straight Power gehen vom Preis dann eher hoch die RM eher runter.

Hello, thanks for the in depth video!
In India there aren't many choices for 750w gold psu with 10 year warranty other than the Corsair. I'm planing to get the RM750 for a Ryzen 5900X and (3080 or 6800XT in future). Seasonic no longer sells their stuff here anymore.
I've read many bad reviews for thr RM750, how likely is it to recieve a bad unit ? Don't want to fry my motherboard and other components from a defective psu.
For the old RM or the new RM series? The protection circuits are actually quite good and complete.
If you prefer seasonic you can get them from other brands, Corsair offers the AX series
@@tweakpc thanks for the reply!
The Corsair unit was already 2 years old apparently. They didn't have the RMx 750 which seems to be a good unit.
I managed to order an Antec Earthwatts Gold Pro 750w . (EA750G Pro 750W 80+ Gold)
This is a rebadge of the Seasonic FOCUS 750 Gold SSR-750FM 750W 80+ Gold with 7 years warranty.
Hab ein neues für 70€ geschossen und werd es morgen mal testen

Ist das 850 Watt Netzteil genauso gut wie die anderen beiden
ja, das 850er findest du auch im Test www.tweakpc.de/hardware/tests/netzteile/corsair_rm_2019_650-750-850/s01.php
@@tweakpc Wissen sie zufällig wie die Abmessungen sind bei dem 850 Watt netz Teil?
Hallo, ja ich habe eine Frage zum Kauf: Im Vergleich zum "be quiet! Straight Power 11 750W", kann ich da auch bedenkenlos zu diesem hier greifen oder was würde jetzt im Vergleich stark dagegen sprechen?
Natürlich kannst du da zugreifen.
Hast du denn bestimmte Fragen?
@@tweakpc Stehe halt nur zwischen den zwei Stück. Möchte halt ein ordentliches Netzteil mit 2 Stromanschlüssen für die CPU. Das hier sah da ganz gut aus...
@@Der_wahre_C17 Viel Falsch machst du mit keinem der beiden Netzteile.
Das ganze ist extrem subjektiv, schau dir nochmal die beiden verlinken Tests an und überlege was dir in welchen Punkt wichtiger ist. Das E11 hat einen sehr hochwertigen Lüfter, das RM hohen Wirkungsgrad bei geringen Lasten. Anmerkung vom be quiet E11 kommt bald die Platinum Version, es könnte sein das es also viele Angebote geben könnte wenn die alten abverkauft werden.

geile siech!
Hmmm... Thermaltake GF1 Reihe schneidet besser ab, in allen Bereichen.
GF1 ist ATX 2.4, Die RM Reihe bereits ATX 2.52. Je nachdem was betreiben wird, schneidet die RM besser ab!!!
Beides Top Netzteile mit Stärken und Schwächen, Hauptsache die Tests waren bei eurer Kaufentscheidung hilfreich VG Thomas
Is the rm850 still the good option to buy in 2021 ?
Yes it is
RM850 is newer version , so you can buy it even in 2025! 👍
Das Spulenpfiepen kann ich hören wenn mein PC ausgeschaltet oder im sleepmode ist. Wurde auch schon ausgetauscht, hat sich jedoch nichts geändert. Sonst stört es nicht so stark, ist ja relativ leise
Hi, Das hat eigentlich nichts mit dem hier genannten Phänomen zu tun und auch nicht mit dem typischen Spulen-fiepen der Grafikkarte. Wenn das sehr sehr leise ist also nur wahrnehmbar wenn man mit Kopf dran geht, könnte das normal sein, manchmal ist ein leichtes surren Hörbar. Kommt das Geräusch denn 100% vom Netzteil?
VG Thomas
@@tweakpc ja kommt vom Netzteil aber es Stör ja nicht
Is the rm650 is a good option in 2021?
yes
@@tweakpc is 1stplayer steampunk PS650SP is good? It is like 50$ dollar cheaper in my country...which do you think is better option?
