Corsair RMx 2021 Series

In so many respects, the Corsair RM1000x ticks all the right boxes the savvy power supply consumer should be looking for. It’s potent coming in with 1000 watts of power output, it has an 80-plus Gold efficiency rating, and as can be seen throughout our testing, it didn’t skip a beat once no matter what we asked it to do. Without a doubt, however, particular highlights of our tests were the amazing low noise-output and, of course, that incredible low ripple noise.

Corsair's RMx series was due for a revamp. A lot of time has passed since 2016, and technology has moved on to allow Corsair to create a better RMx series PSUs for 2021's PC market. Corsair's new RMx series of power supplies come with a new external aesthetic, an updated fan design and official support for features like Windows 10's Modern Standby. Outside of that, a lot of Corsair's RMx series remains the same, such as the series' 80+ Gold efficiency rating, which remains a laudable efficiency standard. With a 10-year warranty and a high efficiency rating, RMx PSU users are likely to upgrade every component in their systems before changing their power supply. The RMx has been designed as a long-haul PSU purchase, and official support for features like Modern Standby helps differentiate Corsair's old and new units.

Nach nunmehr fast drei Jahren laufender Produktion hat sich Corsair dazu entschlossen, seine beliebte RMx-Linie endlich zu aktualisieren und auch den Anforderungen aktueller Grafik-Hardware besser anzupassen. Es gibt wieder fünf Modelle mit Kapazitäten von 550 W bis 1000 W. Alle sind voll modular und der OEM ist immer noch Channel Well Technology, wie auch vorher schon. Und da ich nicht immer nur be quiet! in den Fokus stellen kann und will (auch wenn es der einzige Hersteller ist, der das komplette Line-Up zum Testen dagelassen hat), gibt es heute seit Langem mal wieder einen etwas ausführlicheren Netzteiltest.

CORSAIR bietet das neu überarbeitete CORSAIR RM850x zu einer unverbindlichen Preisempfehlung von 159,90 € an. Damit bewegt sich dieses Netzteil im günstigeren Mittelfeld des Preisvergleichs (bezogen auf Netzteile gleicher Leistung und Zertifizierung). Das Netzteil ab heute in fünf Leistungsstufen von 550, 650, 750, 850 und 1.000 Watt im Handel zu haben. Wir vergeben unsere Empfehlung.

Corsair hat Ende März 2021 eine neue Version seiner Mittelklasse-Serie RMx vorgestellt, welche nun mit einem Lüfter mit Corsairs Magnetschwebetechnik ausgestattet sind. In den anderen Bereichen ist Corsair aber mit einer Effizienz nach 80 PLUS Gold, voll-modularem Kabelmanagement und hochwertiger Technik der Tradition der Vorgänger-Revisionen treu geblieben. Wie sich die 2021er Version auch im Vergleich zum Vorgänger von 2018 schlägt, werden wir anhand des RM850x im Test prüfen.

The RM850x is a definite improvement compared to its predecessor, offering ALPM support and a better fan. The new RM850x is noisier at high RPM, so overall noise output has notably increased. Still, you cannot call the new RM850x loud, but it lost the title of the quietest 850W Gold unit that its predecessor had. I prefer the ML fan over the FDB one since it is more reliable, especially at high operating temperatures.

After almost three years in production, Corsair has finally decided to update its popular RMx line to better suit the needs of today’s graphics hardware. There are again five models with capacities ranging from 550 W to 1000 W. All are fully modular and the OEM is still Channel Well Technology, as before. And since I’m not always just be quiet! (even if it’s the only manufacturer who left the complete line-up for testing), today we’ll have a more detailed power supply test for the first time in a long time.

Having a high-quality PSU pays dividends build upon build. We'd recommend a fully-modular design touting at least 80 PLUS Gold Efficiency, rock-solid voltage regulation and ripple suppression, all wrapped up in a chassis housing a high-quality fan able to run in semi-passive mode. Corsair aces each of those metrics with the RM850x (2021). Featuring the premium ML fan for the first time, there's a lot to like. It's also aimed at the HEDT crowd through provision of three 8-pin CPU connectors for this capacity, offers consistent performance across the board, and at 160mm deep, ought to fit into most chassis.

The new Corsair RMx PSUs have ASM compatibility and perform as well as their predecessors, while even improving on them in some key areas, including efficiency at very light and light loads. The ML fan is a great addition. Not that the riffle-bearing fan on the previous generation wasn't good, on the contrary, but ML fans are better since they do not have any problems operating under high operating temperatures for prolonged periods. Another major change is the third EPS connector with the 850 W and 1000 W RMx models. I can't help but wonder which CPU will need this many EPS connectors, but Corsair will have their reasons.

Viele Empfehlungen wurden bereits für Netzteile mit einem Wirkungsgrad nach 80Plus Gold im Preisbereich um 100 Euro ausgesprochen. Optimierungen an Effizienz und Lautstärke sind aber auch im Jahr 2021 noch Stellschrauben für erfolgreiche Weiterentwicklungen, wie sie Corsair RM650x und XPG Core Reactor 650W im Test darstellen.

This power supply is excellent, that goes for silence, build quality, gold-rated efficiency, and the impressive 10-years warranty. However, Corsair will need to be careful; yes, we consider this to be a more premium PSU; however, this 650W model now will cost 130 USD/EUR, and that, my friends, is steep. You do need to place it in perspective with that ten-year warranty, though. However, perhaps 130 bucks are not that much for such a trivial and important component inside that PC real estate of yours. For a gamer gaming a few hours per day, you need to wonder if you need a Platinum or even Titanium power supply as the price premium might be way more than what it will cost you in energy. Looking at it from the other side, the less power you consume, the better, of course, from that environmental point of view. In the end, we do feel that the RMx 2021 price range could be a notch lower; then again, it just screams out loud how much Corsair quality this product series is and offers. You cannot go wrong with the RMx 2021 series as long as you are willing to pay for the premium. Other than that, the PSU ticks all the right boxes from dark design, modular, efficient, and sheer silence. It is a PSU series that is pure gold, pun intended.
