The RMe series is more affordable than the RMx line, offering in its newest revision ATX v3.0 and PCIe 5.0 compatibility. The RM1000e uses an efficient platform and it also has a silent operation. Performance wise, don’t expect it to be close to the RMx line, because this would create internal competition.
Corsair’s RMe line with ATX v3.0 and PCIe 5.0 compatibility makes its debut today. This line has three members with 750W, 850W, and 1000W max power. All feature 12VHPWR connectors, which can handle NVIDIA’s newest GPU offerings. The RMe line is taxed below the RMx (Shift) one in terms of performance and price, and this is why Corsair used a different OEM for these models, HEC, while CWT makes the higher-end models. All RMe units have a single 12V rail, which is what most users prefer for quite some time now, and the retail prices are $140 for the 750W model, $170 for the RM850e, and $242 for the RM1000e. Typically, the street prices will be lower than the MSRP ones. For example, I found the RM1000e at $171 on Amazon, a huge difference from the MSRP. Corsair uses the “2023” prefix for the new RMe units to distinguish them from the older version. Another way to distinguish the new model is the Cybenetics badge at the face of the box!

I’ve noticed quite a few reviews of this PSU, both online and one person I know personally, which have reported really bad coil whine issues just by turning the PSU on. I’m wondering if there was a large bad batch that went out and the rest are fine or if this is a bigger problem. Regardless, I’m really glad to see a slightly more budget series from corsair to slip between their cxm and rmx series assuming this coil whine issue isn’t widespread.
This is a new product, just got released, so you probably refer to the previous RMe. We didn’t notice any strange issues in our tests, and we have tested almost a dozen different RMe models.
Hello,
Any incoming review of the RM850e model?
Once they send us a sample, sure!
Ah my mistake. Thanks for the clarification. I guess me and a couple others just got unlucky.
Hello Aris,
The soldering it’s bad as it can be. Off centered and off axis SMD, cold joints and manual soldering for some parts. High Power parts with half the flux.
You call this “Average soldering quality”? This thing it’s a fire hazard waiting to happen.
BTW can you give an example of bad soldering in your reviews?
Hi there! This unit is a fire-hazard? It passed hours of testing under the toughest possible condition without breaking or creating any issues.
Where did you see cold joints? If a joint is cold, the unit wouldn’t work at the first place.
Believe me this is average to my eyes. For me notably problems are mostly long component leads which can create shorts and when solder is missing, creating poor connections and increased resistance.
This is bad soldering example: https://www.techpowerup.com/review/xigmatek-maverick-s-500/4.html
The manual soldering done on some SMD parts point me to this cold joints issue, if the QC misses one then here you go.
Also too little flux for the FET’s could lead in time to a crack. Those parts get thermal cycle all day long.
Remember the we don’t buy PSU’s for 1-2 years.
Yeah the example is real bad, thanks for sharing.
Keep up the good work man.
Taka.
You talking crap.Shut up…..
Hello,
I saw two really comprehensive reviews on this Power supply. I decided to go for it for the UK model.
I have the 850-watt model(2023) as I do not intend to use an RTX 4090 or beyond. An RTX 3060 be my sweet spot in GPU.
I notice that on the back of the RM850e box, it says 105C Japanese caps.
On HBuster the review of the RM1000e artwork box just says – 105C Capacitors. I also checked with the RMx model box and it says 105C Japanese capacitors.
The RMe 2023 models do seem to have Japanese caps then.
That was great news as I was going to go for the RMx for an extra 20 UK pounds.
Because of huge capacity shortage, most of the good brands now use whatever they can find and is equal or better than the original specs.
What is the maximum power wattage output before the protection circuit kicks in??
Check in the Protection Features page, for this info, because it relies on the temperature, too.
Hi again,
Since posting my joy about the Corsair RM850e power supply. I had to return it. I brought it from the UK with the UK plug.
My rig is old school. On a Haswell Icore 7, 4960K, Z97 intel platform.I had to upgrade the 500watt power supply for a new GTX 3060 gpu.So chose the Corsair Rm850e PSU.And for future proofing.
To my surprise the RM850e had a coil whine and
a buzzing sound. This sound was reverberating through my 5.1 analogue speaker system. To be sure I removed the gpu to isolate the cause. And the coil whine and buzzing sound was still there.
I also stumbled upon a Corsair forum and they spoke about the RMxxxE. And reported similar tales of woe.
Now I am looking for a new PSU.
Coil whine seems to be a big problem again.
I noticed something strange but since i do not own an oscilloscope anymore maybe you can investigate more.
If and when the time allows i know you busy with the new house.
Since i plugged in the Asus RTX 3070, the coil whine from the card gets back to the 12v and 3.3v lines and the op-amps from my Audigy card deliver it to the headset. The same whine from GPU i can hear in the PSU transformer. There are a lot of users reporting Asus GPU’s for the noise generated by SAP II coils.
I noticed that the 5V line it’s not impacted and tested with an step-up convertor from 5V to 12v and step-down 3.3v and the audio card
on a pci-e extension cable ( just data with separate power). No more coil whine in the headset.
Changed the PSU from an 9 year old Corsair to a Thermaltake GF1 and the noise it’s like 20db less now but still there.
On the Asus card i traced the 12v line from pci-e slot to the memory VRM but cant find usage for the 3.3v, maybe some hidden trace inside PCB.
Most GPUs do coil whine at high FPS, during gaming menus for example.
I know all GPU’s have this more or less. But if I want clean audio looks like 2 PSU’s for me.
P.S. the old RTX2060 didn’t have this issue, headset or external AMP were clean of this noise.
Hi. I have just installed the 1000w version and have a problem with the 12VHPWR cable on my Asus TUF 4090. The red LED of the card lights up when the PC is off (as intended) but it stays on when I switch on the PC. This means that the card does not receive the proper power and remains off so that the PC does not boot. When I use the 4×8 to 12VHPWR Adapter which is included in the card and connect this adapter to 4 cables of the PSU the red LED of the 4090 turns off as soon as I switch in the PC and the PC boots properly. Does this included 12VHPWR cable deliver 600w or not? Or is it just broken?
as far as I know Corsair ships 600W cables with its PSUs. You could measure the Sense0 and 1 pins of your cable with a multimeter, if you have one, to see if both are grounded. IF they are, then the cable is set for 600W.
Thanks for coming back but I’m gonna send the Corsair PSU back as it did not solve my problem. For 2 weeks my PC keeps randomly shutting off, I mean really turning off with no error message, no freeze, no reset etc., just like I would switch off the PSU. I have removed all my sleeved PSU extensions, I have now even tried the Corsair PSU instead of my current Dark Power 11 1200W, but it makes no difference. Must be a kind of safety protection triggered, but it’s so random, sometimes unter high load in a stress test, sometimes “medium” load in games, sometimes desktop only. I have also noticed some kind of short “stutter” (like a short decrease of the general operation noise) coming 1-2 times a day when I watch or play with my UST projector, could it be that I have kind of low voltage dips in my house and the PC PSU is turning off because of that? Could an UPS then help? But then it must be huge one to run the system stable with a 4090 and a 13700k, like 2000VA? Or is there a cheaper way to “stabilize” the voltages for one power plug at home? Too many questions sorry ;)…..
It doesn’t look to be the PSU then but something else. You should check your home’s electrical infrastructure if everything is ok. These low voltage dips, brownouts, definately affect every electronics device, including PCs of course. A 1500VA UPS could support your system, if it is true sine. If you have electrical issues, a UPS could help, yes.
Or do I need one of those which connect to 4 ports of the PSU and not just ?

I would get Corsair’s official cables for the RMe.
