Pros: It arrived in a fairly discrete box that only says Newegg on the outside.
When I lifted the power supply from the box I can feel how solid and heavy it is. It weighs almost 4 lbs.
This is the quietist power supply I have ever used. Drawing 310 watts at the wall with a i7, and a GTX 1080 The fan never kicked on. I had to add extra hardware to get the load high enough for the fan to even spin. And even then, it was still much quieter than the ambient noise in my office.
Looking through the ventilation holes i can see the labels on some of the parts inside. I can see they used 105c rated capacitors and the ones I can read are branded LG.
LG has been making capacitors for a long time and Corsair’s 10 year warranty should reflect their confidence in this power supply.
I don’t want to sound like a brown noser but I have been repairing computers for decades and have never once seen a failed Corsair power supply. There are only two brands I recommend when it comes to power supplies and Corsair is one of them. I have used Corsair power supplies in nearly all of my personal, family and work computers. I don’t know the exact number but I have had at least 50 of them pass through my possession and never once had a problem with one. They seem to last forever. My oldest one is a CX500 which i purchased in 2012 and it is still working today. Cons: Cosmetically I have seen some nicer power supplies from Corsair. It seems like all the power supplies they offer now have the same finish which is a paint over metal and it appears to be less durable than some of their previous finishes.
This power supply has a few spots where the paint is chipping already, and a few of the Allen head screws that keep it together did not take the paint very well and have a bit of silver color showing through the black. It also came in a plastic bag and not a fancy velvet bag like most of my previous corsair units. This is very nitpicky and wont matter to most people but I did notice. Overall Review: Nobody ever mentions cable lengths anymore so I included them here.
It comes with a 5 foot long 16 AWG power cable.
There are 4 sata power cables, providing 14 sata power connectors total.
Two of these cables are 34 inches long and have 4 connectors on them.
The other two cables are 30 inches long and have 3 connectors on them.
The 24 pin ATX power cable is 25 inches long and is the only cable with sleeving.
There is a single 31 inch long molex power cable providing 4 molex power connectors.
There are 3x EPS/ATX 8 pin 4+4pin CPU power connector cables that are 27 inches long.
There are 2x PCI Express Power Cables 8 Pin (6+2) Each cable has two connectors and are 30 inches long capable of supporting 4x GPU connections total.
It also comes with 10 zipties and 4 screws for mounting.

Pros: Seemingly the same energy usage as the previous generations RM650x
Personally, I really like the styling of the integrated grilles.
Fully modular and mostly flat cable design.
More than enough cable length for any case Id be putting it in.
Fan stays off at low load. Cons: Theres not a massive price parity between this unit and the RM750x which comes with better internals.
The flat 24-pin cable is pretty annoying to handle, especially the end thats split into two that plugs into the PSU side.
Some of the PCIe connectors are wired in strangely which puts the orientation as such that its almost impossible not to twist up part of the flat cable to plug it in properly, not really very cool. Overall Review: For the money, you could probably just go ahead and jump up to the 750x for literally 5 extra dollars and get a better power supply (depending on what kind of sales youre seeing). That being said, its still a great power supply and I think itll do just fine. This particular unit performed the same in a power consumption test as the RM650x from the prior generation that I had lying around to compare it to. What that tells me is that Corsair to some extent is continuing to improve these designs. While this until isnt sporting the 80Plus Platinum certification, its also not going to break the bank in terms of cost. I think you either love or hate the flat cables and I personally love them. There were, however, a few troubles with my cables in that the 6+2 connectors required some twisting of the wires to get the proper orientation. This is really annoying with flat cables because well, now theyre twisted and you can see it.
Honestly, whether it makes more noise than the 650x at peak load I couldnt really tell you. My GPU fan makes more noise than it, so its really hard to capture a sound reading. That being said, it definitely stays quiet under all conditions save when the fan actually comes on during gaming. I didnt really even notice any extra sound, just that it was blowing air. All in all, Id say this is a great unit, but if the price is close, just spring for the RM750x.

Pros: The first thing you notice in taking the RM850 out of the box is the weight. It has that premium heft to, solid and heavy. This isnt one of those inexpensive power supplies that seem to be no more than a metal box with a few heatsinks inside. First inspection shows the historic beveled edges design with no bling, just purpose built and classy white legends and a small information label on the top. The power supply is 6 ½ inches in length so its slightly longer then ordinary supplies so make sure you check.
The box contents are sparse. There is the bag of modular cables, a stout power cord and very small bag of zip ties and black anodized mounting screws. There is also a small booklet labeled Important Information that holds the warranty and safety information in a dozen languages. There was no user manual, which I am used to finding but never open anyway.
The modular cables are the by now familiar black flat ribbon design and they are labeled for the noobs not familiar with modular power supply. There are (4) SATA cables, (1) molex cable and strangely enough (3) of the 8 pin auxiliary CPU power cables. This is a first for me but then maybe some of the new, high end motherboards require (3) cables. Also, surprisingly for a power supply of this magnitude, there are only (2) PCIe video card cables. I guess SLI really is dead. Also this the first power supply that doesnt include an adaptor for a floppy connector. Also not included is the old Corsair vinyl pouch to hold the cables you are not using.
The modular cables are a reasonably tight fit and clip into the power supply easily. No fighting to get the connectors in or out. Something else I like is that the (3) CPU 8 pin power Aux cables have clips to hold the 2 (4) pin conns on the motherboard side together. Ive said a few salty words fighting to get these conns seated when the 2 (4) pin ends are just meant to sit next to each other. The Aux CPU cables are approximately 26 inches long so they should stretch from a bottom power supply mounting location up to the top of the motherboard.
I dont currently have a high powered computer on the bench. The only system I have currently being built is a Ryzen 3 3200G system with an ASUS A320I-K motherboard in a NZXT 520 air case. The RM850 is overkill for this system but Ill soldier on. The NEXT 520 Air is a small mid tower and the power supply goes under a shroud on the bottom. The power supply fam faces down and breathes through a filter. Check your cases but it seems like 75% of the cases out there are this configuration. So why is the printing on the side of power supply upside down? I know this is the back of the case and covered by the side panel but still It also shows how far I have to go to find something to complain about.
The cables all fit just fine and of course there was plenty of power. I know this for a fact because I must have turned the power supply on and off fifty times while dealing with a BIOS update problem. Cons: Printing is upside down Overall Review: Corsair is one of those companies that seems to be everywhere. They make so many different computer products that you cant escape the. They are also one of those companies that I know I can trust. I keep returning to their power supplies and memory and cases and All in One cooling units. I have 4 systems at my house and 3 of them have Corsair power supplies. They just work. This one is the same. Its quality built and solid and you just know its going to work. Thats enough for m e.

Pros: Gold certified efficiency
Quiet and cool
Zero RPM fan mode
105C rated capacitors
Supports modern standby mode
Fully modular
Huge selection of cables
10 year warranty Cons: 12V rail deviation
No bag to store unused cables Overall Review: Corsair was originally incorporated in 1994 selling high quality memory. Since then they have branched out in to peripherals, PC cooling, solid state drives and power supplies.
The power supply is often overlooked by many PC builders, perhaps because its not as sexy as the GPU or CPU! I admit that I was indeed one of those PC builders, until I used a series of cheap powers supplies in the late 1990s, one of which killed a motherboard and the other started a small fire!!! Since then, I pay a great deal of attention, and budget accordingly in order to find and use a better quality of power supply. I used a number of Power PC and Cooling power supplies until OCZ purchased them in 2007. After this I started using Coolermaster Power Supplies and more recently Corsair. I have a 1000W Coolermaster V in my main rig and Corsair CV 450 and 550W PSUs in my work PCs.
A few years ago, a 1000W power supply might have made sense, especially if like me you were running power hungry Nvidia GTX980Ti in SLI and an Intel i7-8700K. These days its not hard to find CPUs that have a TDP of 65W and more powerful GPUs like the 6700XT that draws a maximum of 230W. So is a 1000W power supply overkill? Yes it is, so I was extremely happy when Newegg asked me if I wanted to test the Corsair RM 850W power supply, which is a fully modular gold certified power supply.
My test PC has an AMD 5600X, Asus X570 motherboard, 2x16gb of PC 3800 DDR, 2TB NVME M2 drive and 3 older HHDs that I use for backup and media streaming. AMD recommends a 650W power supply for the 6700XT, so perhaps the 850W Corsair is still overkill, however it gives me a little wiggle room for next generation components.
Extensive testing of a power supply can be extremely complex for a PC builder as we dont have access to expensive equipment like power analyzers, oscilloscopes and spectrum analyzers. I can still perform basic stability tests using software to load the cpu and GPU, like Battlefield V with ultra graphics settings at 2560×1440, Cinebench R23, HWinfo, Kill A Watt (to measure power draw from the wall socket), IR thermometer to measure temperature of the power supply under load and a power supply tester to check rail stability.
This power supply has a single 12v rail capable of providing up to 850W and 150W split between the 3.3V rail and the 5V rail! By my calculation, this power supply can deliver a max power of 1000W. The power supply is smaller in size than the Coolermaster V1000W, fully modular and comes with a huge assortment of cables, most of which will not be needed; still they are good quality, if a little stiff. The power supply has a 135mm rifle bearing fan that does not spin at low and medium loads and I never heard the power supply even at full load over the sound of my case fans. My PC is watercooled, so pretty quiet at the best of times. The power supply comes with a huge 10 year warranty, which is a plus as far as I am concerned. Its always great to see companies like Corsair standing behind their products.
Testing
I loaded up BFV Campaign Mode and HWInfo and logged all metrics during the 2 hour gaming session. These were recorded, along with the Kill A Watt wall socket readings and temperature. I played a further hour of Control, to retest all parameters and finally ran 30 mins of Cinebench R23.
Results
At idle Kill A Watt reported a power draw from the socket of between 90-98W, BFV pulled 319-326W with 80% cpu utilization and 80% gpu utilization. Control pulled between 345-354W from the wall with 98% gpu utilization and 28% cpu utilization and Cinebench R23 milticore pulled 145-148W from the wall with 100% cpu utilization.
The PC was 100% stable, no restarts or stutters. Temperature at the PSU never exceeded 35C during my testing and was inaudible.
According to HWINFO 12V rail deviated more than I would have liked at 1.6%.
5V rail varied from 4.94V to 4.98V or 0.81%
12V rail varied from 11.98 to 12.172V or 1.6%
3.3V rail varied from 3.264 to 3.280V or 0.49%
Conclusion
I was impressed with the power supply; it took everything I could throw at it. It was quiet, kept cool and was well behaved, no shut downs, stutters or reboots. It also appeared to wake up my pc a little quicker than my Coolermaster, although I did not specifically test this. I docked one star for the 12V rail deviation, 1.6% was definitely higher that I liked.
Recommended.

Pros: If you’re looking to power up a high-performance computer, this thing is a beast. It can handle up to 1000 watts of power, which means it’s perfect for hardcore gaming or any power-hungry tasks you throw at it. 80 Plus Gold certification, which not only makes it super efficient but also saves you some serious cash on electricity bills and you know that it’s built well. If there is one thing you don’t want to cheap out on, it’s a power supply. Being fully modular, so you can connect only the cables you need, making your build look clean and professional. I also like that they provide you with a beefy looking power cable, not some wimpy one. I had this power supply hooked up to a i7 9700k with 32GB of RAM and an Intel Ark 770. No problem at all, I mainly play RUST and this power supply wasn’t even breaking a sweat. Good venting for the heat that was coming out, but honestly it wasn’t too bad at all. Much better than my last EVGA 750 watt power supply. Cons: First off, it’s quite pricey compared to other power supplies out there. If you’re on a tight budget, it might be a bit of a splurge. Also, because it’s a high-wattage unit, it might be overkill for some average PC builds. Unless you’ve got some serious power-hungry components or future upgrades in mind, you might not fully utilize its capabilities. Another thing is that the cables, although of good quality, could be a tad bit stiff and hard to manage. So, keep that in mind if you’re all about that clean cable setup, it’ll take a bit more work to keep it clean and hidden. Overall Review: If you’re in the market for a high-performance power supply, the CORSAIR RM1000e is definitely worth considering. It delivers the power you need for demanding tasks, boasts excellent efficiency, and comes with a range of useful features like its modular design and built-in protections. Just make sure to evaluate your specific requirements and budget before making the final decision. If you’re a serious gamer or tech enthusiast who wants top-notch performance and doesn’t mind investing a bit more, this power supply won’t disappoint. However, if you’re on a tight budget or have a less power-hungry system, you might want to explore other options that better align with your needs. Ultimately, it’s all about finding the right balance between performance, budget, and future expandability. I’ll run this power supply for a long time. I really like it.

Pros: – The design on the power supply is sleek. Most power supplies, if not all, look identical except for maybe colors. This power supply has it’s own style with the geometric grills and the chamfered edges. It just looks sleek.
– It comes with enough wattage providing ample power for high-performance computer systems, including gaming rigs and workstations. I’m personally using a 5800x3d and a 3080 12gb gpu without any issues.
– This power supply is silent. It features a Zero RPM mode, where the fan remains idle under low to moderate loads, ensuring silent operation. The fan spins up only when necessary, providing efficient cooling while minimizing noise.
– One of the other things I’ve noticed about this power supply is how light it is. It’s only 3.5 pounds. I’ve seen similarly spec’d power supplies come in at a whopping 5.5 pounds. It doesn’t seem like a lot, but when you combine all the weight of the other components, it definitely adds up. Cons: – One of my biggest gripes about the power supply is that it doesn’t include premium sleeved cables. Most power supplies these days come with decent cables. Although it’s mainly aesthetic, a premium power supply should at least come with premium cables. Overall Review: – I highly recommend the CORSAIR RM850e power supply for users seeking a reliable and efficient PSU for their high-performance computer systems. Overall, the power supply offers exceptional quality and performance, making it a worthwhile investment for enthusiasts and professionals alike.

Pros: – EPS and PCIe cables use the same slots on the PSU.
– Comes with a dedicated direct 2×8-pin to 12VHPWR cable rather than just an adapter.
– Type 4 standard cables, so they can be used with other Corsair PSUs that are Type 4 standard.
– Small form for a high wattage PSU.
– Good packaging to secure all contents.
– Cheaper than the RMx lineup for the features. Cons: – Comes with only 2 1×8-pin PCIe cables; daisy-chain PCIe/VGA cables should be rid of at 850W and higher PSUs in my opinion.
– Typical, thick 24-pin connector that is hard to fit/bend in some cases with smaller cable management cutouts.
– Stock cables might be just shy of not reaching connectors on a motherboard/ and GPU in full-tower cases. Overall Review: I have never been a fan of Corsair PSUs by their price alone, but the features of this unit are enough to warrant the price and value. If you need a 1000W PSU, then this is a reasonable and tier A choice based on the Cultists Network’s list. You can see from the pictures that the unit is relatively small for 1000W at a depth of 150mm and weighs an estimated 3.66lbs or 1.66kg. My current daily PC has a 4070ti and 13600KF pairing, so I will not come anywhere near the rated wattage while under a typical gaming or workstation load. Guess I will have to test its limits and protections with a modded GPU and some XOC ;). The included 12VHPWR cable can handle 600W of power and supports an RTX 4090 on its own without adapter cables many 40 series cards come with. Overall, I think this is a competitive 1000W PSU for those who need or just want it for future headroom. No issues at all for me yet while using it.

Pros: – Compact
– Modular
– future proof
– good assortment of cables
I don’t know how they keep doing it, but they keep making power supplies smaller, more powerful, and more efficient. This thing is barely bigger than the size of the fan cooling it. It is fully modular so you won’t have to have unused cables taking up space in an otherwise clean build. The layout of the modular connectors also makes it easier to make changes unlike some others where certain connectors block you from removing other cables until they are removed. It has two types of sata power connectors to maximize case compatibility. 1 with straight connectors and 1 with 90 degree connectors. It also includes a power connector for 40 series Nvidia cards. It also runs very quiet and includes a 7 year warranty. Cons: There aren’t many. Each sata cable can power up to 4 devices. If you have more than 4 hard drives you may run into clearance issues on tome smaller cases with the straight plugs. I’ve had cheaper power supplies include multiples of each type. The main mother board power cable is very stiff and difficult to bend. This could lead to the mother board connector becoming disconnected while you are bending it into position. Make sure you check the connector before closing up your case and attempting to power it on. Overall Review: This is a great power supply. Powerful enough to handle powerful loads and quiet enough so that it won’t be the component making noise in your pc. The few cons there are will only affect niche users. For most users this power supply will give them all the power they need and still leave room for future upgrades.
