The RMx Series, a family of low-noise PC power supplies that maker Corsair has described as being one of the quietest and most reliable options available, is now available with several improvements, including ATX 3.1 compliance, a native ATX 12V-2×6 connector, and a manual fan speed control knob, Corsair has announced. These modular PSUs, which feature Gold-certified efficiency (up to 91%) and an A+ noise rating from Cybenetics, are cooled by a 140 mm Fluid-Dynamic Bearing fan with a magnetic dome structure and manual fan override knob.

Corsair on its new PSUs:
Available in 750W, 850W, and 1000W models, every RMx Series PSU is fully ATX 3.1 compliant and includes a native 12V-2×6 connector to support both current and future high-end GPUs. The 140mm 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-2×6 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 150mm x 86mm x 160mm and include a wide variety of cables and connectors that vary based on the model purchased.

The original RM series was the one that shook my confidence in Corsair PSUs. They used to be my “didn’t need to wait for the review” brand. Not after that.
Hello Seasonic

The only Corsair PSU I have is cuz it was built by Seasonic.
I've never had an issue with my Corsair PSU's. Them and Seasonic are usually who I go with.

I never had any issues with the ones I purchased either. I didn't own an RM series.
But they were a bulletproof brand for a long time. You could count on every model going into a review and crushing it.
Until that RM series kinda choked. Then they were just mere mortals again - like almost every other PSU vendor out there.
Right now Seasonic is the only brand I can think of that's more or less nailing it with every model out there. Some may be better than others but none of them are downright failing or dangerous.
That first RM series from Corsair was pretty bad if I recall. They shored it up with subsequent releases. I'd link to the H review, but it's no longer there =(
I leave you with this instead, which is a poor substitute

That's when I stopped looking at them, think jonnyguru had some review of them but that site is gone too, but I think since he's moved to Corsair they improved again, still mostly go for seasonic ever since.

I had the RM1000 unit for a while, and it seemed to be very good though the system it was in the PSU was probably overkill.
