Fantastic
Had this in my gaming pc for some time now. I have had no issues. Was really easy to install and runs some pretty high end hardware. Worth every penny
It's completely sile
I always choose much bigger PSU than I need to not trigger it’s fan, just for the comfort of silence. This one does make electrical noise at all. Very good product.
I don’t think anyone here needs convincing of the quality control that goes into Corsairs PSU’s and this 1000w shift model is no different. Powering my 4090, i9 14TH gen without so much as breaking a sweat. What more can I say. Great price on a great product, strongly recommended!
Quality PSU
Easy to install. Great features. Modular helps keep your case tidy, with no unnecessary cabling needed to be tied out of way. This will also assist air flow in case. Silent in operation.
Excelle
Excellent nothing more to say apart from the ports being on the side make feeding cables from the inside of the case to the outside makes cable management a dream.
Comfiest Power Supply
Standard Fully Modular PSU, Perfect White Colour with Cables to match.
Straight to the point:
Put all the cables in and installed power supply, forgot one CPU cable as needed 8+4pin, managed to have plenty of space to fit my hand in and plug the cable in the PSU, so saved much time of unscrewing and removing it to just add one cable, also future proofs my build in case I upgrade to a future GPU with more than only one 8pin cable I can simply add it whenever.
Cables let it dow
I have the 750 Watt version of this PSU and the cables are nicer and tidier on that cheaper model
The cables for the 24 pin power and the video card are a tangled mess.
And why in todays world of high powered video cards would they still continue with the 2 connectors on one cable nonsense.
Only You Corsai
I have been buying only power supplies from this company for years. And I have never been disappointed by them. Corsair is top of the top. Efficient, quiet and effective. I installed hundreds of these power supplies in the computers I built. And I will be loyal to this brand for the rest of my life. Only you-Corsair.
Worked as it should
I am not expert on PSUs but the one in my gaming PC died and I needed a replacement. I read some reviews and decided on this one. I was a bit worried because it is my first modular unit, but it was early to install. Lots of cables came with it, so I have quite a few left over (which I will probably loose). It came next day which was perfect.
So, easy to fit, quiet, flexible, well known make, what is not to like.
Good powerful psu
In use for about 6 months now, no issues ( although is a bit of overkill for my rig).
Mention to be noted that even it is fully modular, one must be careful when choose it how much space is available in the pc case ( width wise) if installed at bottom as the ports will be to close to the edge and will have to install it upside down ( sucking air from inside of the case, douable but not ideal). Plenty of space to be installed in a Fractal R5 XL but not enough ( for correct position) inside a Define R5 (mid tower pc case).
Apart this, recommended this psu. Powerful and quiet.
Wouldn’t recommend with a top mounted psu case
Great power supply other than the fact I have a top psu mounted case and it just makes it terrible to run wires from most of my wires are pressed against the top of my case properly not going to be good long term
Great PSU. Not so great price.
The cost of PSU’s much like GPU’s is kinda crazy right now. However if you need something to drive those expensive GPU’s you are going to require a decent PSU and this one is no exception. I cannot vouch for its efficiency but it is quiet and very easy to install. The side cable (thus its name ‘SHIFT’) is a great idea if your case has plenty of space to hide it behind. The PCI 3.0 spec was the other reason I purchased this PSU so I could have only one 12VHPWR cable connected to my brand new RTX 4080 Super and whilst not the most attractive looking cable at least it’s better than the 3 into 1 adapter supplied with the card. I might get a fancy braided cable later on if it bothers me but right now it does the job it is intended to.
Great Corsair quality and reliability, shift does make wiring quite a lot easie
Needed this for a gen 4 GPU power upgrade and had needed the extra watts. My previous RM650x lasted for 8 years running a heavily overclocked 980Ti/1080Ti and a 9900k without fail, sometimes whilst mining. No issues with reliability ever.
The RM850x seems to be of the same great quality, and the shift wiring really makes cable management easier in cases where you can’t slide the PSU out of the back of the case.
I recently upgraded my gaming rig with an Intel i7-14700KF processor and an RTX 3060 Ti graphics card, and I needed a power supply that could keep up with the demands of these high-performance components. The Corsair RM850x has proven to be the perfect choice.
First and foremost, the fully modular design of this power supply has made cable management a breeze. The ability to only use the cables I need not only keeps the inside of my case tidy but also improves airflow for better overall system performance. Having 3x 8 pin CPU ports is also a nice-to-have, in case I decide to upgrade my motherboard and or CPU at any point.
In my opinion, it’s very important to purchase a power supply from a reputable brand, known for producing solid power supplies, to ensure that the expensive components you are powering, stay safe, and get the power they need. Investing in a good branded power supply should also help it outlast the other components’ lifespan.
Running on an Intel i7-14700KF and an RTX 3060 Ti, power efficiency is crucial, and the RM850x with its 80 PLUS Gold certification does not disappoint. It efficiently delivers power to my components, ensuring stable and reliable performance during intense gaming sessions and demanding tasks. Both components have also been overclocked, and the RM850x doesn’t break a sweat.
The 850 watts of power is more than sufficient for my setup, providing headroom for any potential future upgrades. The power supply operates quietly, and the Zero RPM fan mode ensures that the fan only spins up when needed, keeping noise levels down during lighter loads.
Corsair’s attention to build quality is evident in the sturdy construction of the RM850x. The components feel durable, and the unit itself exudes reliability. This power supply comes with a 10-year warranty, offering peace of mind and showcasing Corsair’s confidence in the longevity of their product.
In conclusion, the Corsair RM850x 80 PLUS Gold Fully Modular ATX 850 Watt Power Supply is an excellent choice, at the right price. I am certain it’s going to last me 10+ years.
Solid and reliable however…
The wires are quite ugly that come with this product so if you are interested in aesthetics at all get ready to shill a little on some extenders or outright new ones.
Great quality 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 purchased this power supply after spending a week reviewing numerous power supplies online. This PSU is listed as a tier A high end power supply on cultist reviews
I had recently upgraded my GPU to a 7900xtx and my Seasonic prime 850w could no longer handle the power demands put upon it so needed to upgrade.
Due to supply shortages and high prices in the UK currently I decided to go for a cheaper option and so far I am glad I chose this power supply.
My first choice would have been a platinum or titanium rated Seasonic supply but this gold rated supply from Corsair is still impressive for the price.
Another benefit this PSU has is that it supports the new ATX 3.0 standard and comes with the new 12vhpc cable for when I need to upgrade my current GPU. The unit also comes with enough PCIe cables for any GPU requirement. Mine uses 3x cables. You get 6x cables total with 2x being able to daisy chain with but I don’t recommend you do that and instead use the 4x single 6/8pin cables instead.
The unit fits nicely into my PC case without issue however my case is very large. It’s a cooler master cosmos s2 case. Had this awesome case for nearly a decade now.
I am very happy with the build quality and the unit is extremely quiet with my PC under full load.
I would highly recommend this power supply if your on a budget but you do need to make sure it will fit in your case first as cables are on the side of the unit.
Convenient design, mediocre cables
Putting the cables on the side makes a lot of sense (if your case is wide enough, I did my research beforehand, so should you). The cables are quite stiff and not sleeved, which makes certain cables a bit scary due to single cables which i assume are for sensors being loose and strained. The 12VHPWR cable is too short, a wide case is likely going to be tall too, I had to do strain mine a bit more than is comfortable to plug it in, I would not keep it that way long-term.
Overall tho, great PSU and rates high in tests.
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.
