Magnetic Levitation Cooling Meets High Efficiency
CORSAIR RMx Series fully modular power supplies are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC with the cooling power of potent Magnetic Levitation fans.

135mm Magnetic Levitation Fan
Utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low bearing noise, and superior reliability.

High Efficiency
With upwards of 90% peak efficiency, RMx produces less noise and less heat, which means less time worrying and more time gaming.

Fully Modular with Multiple EPS12V Connectors
Completely modular cables means you only connect the cables your system needs, and the wide range of included cables adds broad compatibility with modern graphics cards and motherboards.
Also compatible with the 12-pin GPU Power Cable for the hottest new GPUs.

Zero RPM Fan Mode
At low and medium loads the cooling fan switches off entirely for near-silent operation, but once the action picks up, the fan activates, ensuring critical component temps stay in check.

Technology and Reliability
For consistent, reliable power and superb electrical performance, each RMx Series power supply features a robust resonant LLC topology with DC-DC conversion, and 105°C rated 100% Japanese capacitors. With precise timings, RMx supports Microsoft Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency.

CERTIFICATIONS
The Cybenetics organization measures efficiency and noise levels across the PSU’s entire operational range, using more than 1,450 different load combinations.

The "Gold" efficiency rating is defined as ≥87% to <91% (depending on input voltage).

The "A-" noise level test is measured in those same configurations to be ≥25 dBA & <30 dBA under noise data averaging.

TEN-YEAR WARRANTY
Ten-year warranty backed by the CORSAIR global technical support team.

YOUR BUILD, YOUR WAY
Every fully modular CORSAIR PSU is compatible with a wide range of CORSAIR accessories. From individually sleeved cables in a variety of color combinations to 12-pin micro-fit GPU cables and 12VO motherboard cables, complete your build your way.

OK PSU - fan a bit noiser than hoped for

The PSU is fine, I'm sure that in general the build quality is worthy of its reputation. However what has disappointed me slightly is that the PSU fan has a slight audible rattle to it. It's barely audible at my sitting distance from it at about 1m+ in a quiet room, but I can just hear it enough for it to disappoint me. I have no idea if this is faulty or typical, but I've opted to accept it. If it was located under my desk or further away I probably wouldn't be able to hear it. Also the fan comes on slightly more often than you may expect - although the marketing material states that the fan won't come on below 350W, it doesn't state that it will also come on whenever the PSU temperature reaches around 40 degrees, which in a warm room and a PC under load is easily achievable, even below 350W. With my setup I had generally expected the fan to never come on because I would rarely if ever exceed 350W, but the temperature trigger still trips it on. Just something to be aware of. So typically I hear the PSU fan after gaming once all the other fans have settled down but the PSU is still trying to cool itself.

Great service and kit

Equipment is great quality and works perfectly. My main reason for the score is the quality of service. For some reason my Google pay used the shipping address as my address from 3 years ago, I was panicking and emailed Customer services, who were brilliant and managed to change it before it was dispatched which was within 2 days of ordering!
