CORSAIR Updates RMx Series PSUs with ATX 3.1 Compliance and Native ATX 12V-2x6 Connector

[btarunr]

Corsair today announced an update to its award-winning low-noise RMx series of power supplies with ATX 3.1 compliance, a native ATX 12V-2x6 connector, a manual fan speed control knob, and other improvements. Boasting Gold-certified efficiency (up to 91%) and an A+ noise rating from Cybenetics, the new RMx series includes fully modular, ultra-flexible embossed cables that simplify cable routing even in the most challenging of PC builds. Cooled by a 140 mm Fluid-Dynamic Bearing fan with a magnetic dome structure and a manual fan override knob, the RMx series remains one of the quietest and most reliable power supplies available.

"We're pleased to launch the new RMx Series with an entirely new electrical design that includes a six-layer PCB for better thermal and electrical performance, an upgraded fan, and full ATX 3.1 compliance," said Jon Gerow, Director of Power Supply Research and Development at Corsair. "We're also happy to announce it achieved the Cybenetics Gold rating for efficiency and the A+ rating for audible noise." Each RMx power supply features 100% Japanese electrolytic capacitors and delivers its rated power output at a 50°C ambient temperature, ensuring reliable power and longevity even under high-stress conditions.



Available in 750 W, 850 W, and 1000 W models, every RMx Series PSU is fully ATX 3.1 compliant and includes a native 12V-2x6 connector to support both current and future high-end GPUs. The 140 mm FDB fan is PWM controlled and features a half-dome structure that reduces surface friction, resulting in less noise and an improved lifespan. The specially calculated fan curve ensures fanless operation at low loads and minimal noise as power ramps up. Users who wish to override this can do so quickly and easily using the included knob on the rear of the unit.

The RMx Series features fully modular, embossed cables that are sleek and ultra-flexible, capable of making tight bends when connecting to nearly any device within a case, allowing for easy concealment. The 12v-2x6 cable includes low-profile combs for a clean look that compliments your GPU rather than obscuring it. The RMx PSU enclosure is all-new, featuring a stamped, low-restriction fan grill and an improved connector layout with clearer labeling. For users who want a splash of color, the RMx Series is compatible with Corsair Premium Individually Sleeved Type 4 PSU cables and our ARGB PSU cable strips, sold separately.

RMx Series power supplies measure 150 mm x 86 mm x 160 mm and include a wide variety of cables and connectors that vary based on the model purchased.

Anyone still consistently reviewing PSUs these days? There were sites in the past dedicated to this but recently at best one can get a recommendation for whatever is absolute best at the time but nothing more.

For PSUs I follow those 2 sites:

PSU Tier List rev. 17.0g - Cultists Network

PSU Tier List will help you to choose the best PSU out of hundreds of models on the market. From budget to the highest end Power Supplies.

I was following the cultist list but it appeared to be "abandoned". I'll check the second one more closely.

Ye, I hate buying PSU, that makes high pitched whistling sounds.

a few others sites do it but their reviews are...questionable

just to name a few that still do it, hardware busters is basically dedicated to it

He just regurgitated Aris lists to match his personal opinion, kind of pointless when Aris does his best of lists and has a running point system of all reviewed units

 

[JasBC]

Ah, so this was the reason they were running such a big sale on the RMx-units huh. . .

 

[ajcardiac]

@btarunr Thanks for the article.
The links to Corsair are now bad '404: Page not found'.
They seem worth a look when I next build.

 

[Nater]

Queue the shady Amazon sellers hocking previous years units as new.

 

[KLMR]

Look at the 12-2x6 cable. Where is going to fit if the GPU is big?

a CGI of a PSU internals...

Seriously... are you taking medicine? PR department, I am talking to you.

they work now

the only question I have is, does the manual fan knob go to 11?

 

[maxfly]

Love the old school fan knob idea but I can't tell what it goes up to.

You know what? I WISH!

Back in the day, I worked a while for Ultra. I designed a fan controller that could run the fan at 10% increments, highest would actually push 13.2V to the fan. I submitted the drawings for the control interface and this "overdrive" setting was labeled "11".

NOBODY GOT IT! NOBODY! They said, "we need to just label this 1 through 10" and I did the whole "but this one goes to 11" bit AND NOBODY GOT IT!!!!!

you were missing the mullet

Hmm... they're still using their Type 4 cables on this series. I was thinking they would make the move to the smaller Type 5 connectors like they did with the new SF and RMx SHIFT lineup.

No. Because it's not necessary. On the SF, it's necessary so an appropriate number of connectors can be placed on the PSU considering the wattage. On the Shift, there is an obstruction between the main PCB and the fan that limits the number of rows of connectors to two, so you have to use the smaller Type 5 connectors in order to get an appropriate number of connectors.

Everything happens for a reason.

And it fooled me for a moment. What a nice wireless and blobless PSU, with no wires and no black blobs of glue! Sadly, no one is able to do that yet.

Makes sense. I'm not against Corsair staying with the Type-4 cables (looks at two braided Type-4 kits in a box at the corner of the room). I was thinking that the Type-5 cables were some sort of successor to it with the newer models.

 

[Leatherjacket]

Very interesting! I am very surprised Johnny Guru is apparantly now in favor of the 12VHPWR connector now despite Corsair rejecting the native connector with their first ATX 3.0 psus. I mean the reasons were totally understandable but anyway...
Biggest selling points are defintely the TYPE 4 cable connectors and the manual fan knob. I give Corsair big credit for not abandoning all my custom cables! Hats off to the Corsair PSU department! I'll definitely buy one of these!

 

[Makaveli]

hmm does corsair still have an AX line in 2024 or is HX most current?

Queue the shady Amazon sellers hocking previous years units as new.

I am very careful what I buy from that company because they are a cover for thousands of sellers that they know are selling fake stuff but don't shut them down.! I try to buy as little as humanly possible from them, usually desperation or they are the sole seller are the reasons why, otherwise I try to go with known online PC Hardware stores that are often the same price anyway. Mild rant over.

ordering from Amazon is fine as long as you confirm this.

You don't even necessarily need the "Sold by", as long as it ships from Amazon it's already at least 90% safe.

 

[Wasteland]

Good stuff. Looks like they ditched the inline capacitors on the stock cables--that alone is a big plus.

I'm running three of the older version of this PSU at the moment. Don't anticipate their needing replacement any time soon. But when I do need to replace them, this is what I'm getting. Thanks for your work, Jonny.
