I highly recommend the RMx series over the RMe series. The RMx is completely silent in Idle and during load. In comparison to the RMe it has terrible coil whine during idle and sometimes it would disappear during load but be back again when idle. I wish I had done some research before purchasing the RMe and even getting a replacement which had the same issue.
I bought this whilst building my first PC, it was extremely easy to set up, came with all of the cables (and more) that were needed.
It was very easy to set up due to everything being labeled, it is very quiet and efficient. If you are in need of a powerful power supply I would recommend this product!
When building a PC for gaming you should spend a decent amount on a quality power supply.
Some people buy a cheap PSU then after the build have problems with then diagnosing what is wrong.
With my build i could have gone for 750w but for the sake of another 10 i thought i would get the 850w.
It looks like a high quality product. Comes with all the power cables you need for your build.
Having all of the plugs on the side is a simple concept but helps alot for visibilty when building.
Hoping it lasts a long time
I didn’t expect anything less than an exceptional product from Corsair. No 1 for memory and PSU’s for me
I did have a 750 watt HX750 PSU still working perfectly from previous build /system which was working perfectly after more than 10 years but my new PC build looked to need a little more power to be safe so went with this RM850x SHIFT from Corsair. Wow! this new shift layout of side connections instead of the conventional rear of PSU is perfect, specially in my new Lian Li 011 D Evo which makes cabling even more easy and neat, I didn’t need the Drive Tray above the location for PSU in the case so this shift PSU from Corsair fits beautifully in this Cases layout and is near to SILENT in operation
10/10 to Corsair for another great solid built product
10/10 to Amazon for speedy service as per usual
As with most things Corsair make, this is really well made and feels like a quality product.
Super easy to install and the cables it comes with are of a very high standard
Excellent and quite power supply. Comes with ample cable selection and totally modular. I, unfortunately, was using it for a micro atx case without sufficient clearance for the cables to sit comfortably into the PSU. My mistake and not that of the PSU or seller but just a word of warning for others.
i use this to support my rtx 3070 and a i9 13900kf with loads of rgb. this is definitely worth it even if it’s to much power as it won’t need a upgrade anytime soon.
Having a direct 12VHPWR adapter for my RTX4080 is a relief rather than depending on an adapter. Can replace the cables for a Cablemod set later down the line as the current cables are not plastic, but I’m really happy with it.
Pros:
Power Capacity: With its 1000 Watt capacity, the RM1000x offers more than enough power to handle high-end components like the RX 7900 XTX graphics card and other power-hungry components. This ensures stable and efficient power delivery even during demanding tasks or gaming sessions.
Efficiency: The 80 PLUS Gold certification indicates that the power supply is highly efficient, converting more power from the wall outlet into usable power for your PC components. This can help reduce electricity costs and waste heat, keeping your system running cooler.
Fully Modular Design: The fully modular design allows you to connect only the cables you need, minimizing cable clutter inside your case. This not only improves airflow but also makes cable management easier during the build process.
Build Quality: Corsair is well-known for producing high-quality PC components, and the RM1000x is no exception. The power supply is built with premium components, which contribute to its overall reliability and longevity.
Quiet Operation: The RM1000x features a Zero RPM fan mode, which means the fan won’t spin at low to moderate loads, resulting in quieter operation. This is especially beneficial during light computing tasks or when the system is idle.
Overcurrent and Overvoltage Protection: Corsair equips the RM1000x with multiple safety features, such as overcurrent and overvoltage protection, to safeguard your components against power fluctuations and potential damage.
Cons:
Price: The RM1000x is positioned as a high-end power supply, and the fully modular design and high wattage capacity can make it relatively expensive compared to lower-end models. However, the extra cost is often justified by the added benefits and build quality.
Overkill for Some Setups: Unless you are running a very power-hungry system with multiple high-end components or are planning to upgrade further in the future, the 1000 Watt capacity might be overkill for some users. A lower wattage model could be more cost-effective for more modest setups.
Overall, the Corsair RM1000x is an excellent choice for enthusiasts and gamers who demand a robust, high-performance power supply to support their powerful components. It’s efficient, reliable, and has a modular design, making it a top-tier option for those willing to invest in quality hardware. However, if you don’t require the full 1000 Watt capacity, you might consider looking at other options within Corsair’s lineup that suit your specific power needs and budget.
I purchased the corsair power supply as it is a high end unit which does what it says on the tin,
I had a mysterious fault with my PC where the unit was cutting out when certain programs were loading up heavy graphics, it turned out that my original power supply was not able to respond to the power demand thus causing this anonymous cut out fault.
In my experience Corsair produce outstanding product which is highly durable.
I feel this is safe than one old power supply
I recommend to use this
I should have first to check any fault when power supply know it’s too dangerous to stop and my computer I understand why I should have learned my mistake.
Much thanks it’s great!
No problems so far, perfectly reliable, but you need to be sure about your case’s internal width. If this was a few millimetres narrower I wouldn’t have had to chop out some of the sound deadening material from my case. The cables are still being pressed against the side a bit too much for my liking, but it seems OK.
Power supply is study and very well built so when plugging a mains cable into it it doesn’t bend or pull on the psu. It comes with a range of different cables with different variations for different pieces of hardware. Having the connectors on the side is a lot better for most atx cases (might not be compatible with some cases due to clearance) as bigger psus don’t give a lot of room for hard drive cages and also it improves installation when plugging in the cables you need. The noise level from this power supply isn’t bad as the fans are very quiet.
The Bad:
Even though this is a very good power supply the only issues I have with it are the cables that come with it are not sleeved and the pcie connector (2+6 pin) the two pin is bridged from the 6 pin showing that costs were cut on the wires. My complaint about the cables not being sleeved is because it makes the cables look cheaper and more likely to get damaged. A lot of cheaper power supplies even have sleeved cables even if they are the mustard and ketchup colours.
Installed this into my Sharkoon TG5 RGB Case and it fits perfectly, and lets me route cables a lot nicer than the previous power supply I had, powering a 5800X3D and a 5700XT it’s not exactly using all 850w but it’s nice to have the preparation for a more power hungry card. Haven’t done too much testing but I currently can’t hear any coil whine which is another nice improvement over my last PSU. Overall, a recommend if your case will accommodate it.
The connections are on the side, it’s not a deal breaker but does mean you need a reasonably wide case , and an opening to the PSU behind the motherboard backplate
Great item in general and fits may case and PC well (AMD 9750x and GTX1070).
My only complaint was that the wires are quite stiff and fitting the side case onto the case required some careful management and use of a hair drier to help smooth out bends.
I received the package damaged which is seen in the pictures but everything inside seems to be fine, I will install this unit and see if it works but it looks good there are a lot of cables but since it’s a fully modular power supply it should be easy to install. I would say you should probably get it from a different seller and when it’s on discount but it’s good value either way.
While there isn’t a whole lot to say about a power supply, it is absolutely solid. The modular cables are a godsend, saves all the clutter when trying to cable manage. Speaking of wires, there are PLENTY of modular cables included for all your needs, Corsair is very generous with them. The construction is pretty nice too, doesn’t feel cheap or tacky which is what you would expect from a high-end Corsair product. The “Zero RPM” fan is also an excellent addition, the fan won’t spin up for a while until you start running 3D applications, i.e. games, heavy loads, etc.
My only minor complaint is due to the size of the unit and my mid-tower case, I have had to remove the case hard disk cage to fit my cables, and I have lost 3TB of hard drive storage as a result. This is a very minor problem for me as I am trying to phase them out of my system in favor of SSDs.
1. Fully modular so dont have to worry about excess cables clogging up the case
2. can support large graphics cards with high power needs Eg: my 3080 needing nearly 500W at times.
3. silent fan mode meaning the fan wont spin under low use leading to a quiter pc overall despite output.
4. easy install, as with most PSU 3 or so screws in the back and your sorted
5. Plenty of outputs for many devices/ hungry cards etc
Cons:
1. All PCIE cables are daisy chained/ pigtail cables, there is some debate whether these are safe/ ok to use when a card needs 2×8 pin PCIE but the general advice is to use 1 cable per 8 pin slot leading to the second pigtail/ daisy chain dangling in the case. Not that bad but not perfect if you want an incredibly clean pc.
2. the labelling on the back of the psu is good but a little confusion between which of the ports is sata and which is pcie
3. sata power cables are daisy chained, not bad for power consumption etc but leads to some strange cable management in the rear of the case HOWEVER this can be a pro , the daisy chained cables are almost perfect length to have 2 HDD in the bays with the cleanest cable management ive seen out of the box. SSD not so much so its a give and take point.
All in all, id’ definatly buy it again and its good value for money
