Corsair RM850, RM Series, 80 Plus Gold Certified, 850 W Fully Modular ATX Power Supply – Black


Ready for Modern Standby

Modern Standby is an upcoming feature for Windows 10 that vastly improves your PC’s sleep and wake functionality. The technology allows your system to wake from sleep more than twice as fast and maintain a network connection during sleep to continue downloading updates and receive notifications.

  1. 80 Plus Certified

    The RM Series delivers power at up to 90% efficiency, lowering energy consumption, noise, temperatures, and your power bill.

  2. 105°C – Rated Capacitors

    Using industrial-grade electrolytic capacitors, RM Series power supplies offer the unwavering power and long-term reliability you demand from a CORSAIR power supply.

  3. Zero RPM Fan Mode

    The RM Series’ cooling fan doesn’t spin until you need it, for near-silent operation at low and medium loads.

Tuned for Low Noise Operation

A 135mm rifle bearing fan with a specially calculated fan curve ensures that fan noise is kept to a minimum, even at full load. When at low and medium loads, the fan stops spinning entirely until it’s needed, resulting in virtually silent operation.

Compact Size

A 160mm-long casing ensures an easy fit in almost all modern enthusiast PC cases, providing more space for cable management and airflow in your chassis.

  1. Ten-Year Warranty

    Corsair provides a ten-year warranty on all RM Series power supplies; your guarantee of reliable operation that will last across several system builds.

  2. Multiple-GPU Ready

    PCI-E connectors to power dual or triple (RM850 only) GPUs for your most ambitious PC gaming builds.

  3. Fully Modular Cables

    Use only the cables you need for quick and easy installation, simplifying routing and cable management. Store your unused cables in the included cable bag.

    Powerful PSU with zero complaints.
    I’ve been using this PSU for a fortnight or so. From my limited experience, it’s done exactly what I need it for.

    The instructions manual is a little vague but there’s an abundance of “how to install” on YouTube and on the web.

    Noise level is minimal.

    I would recommend and am very happy with my purchase.

    I like the modular system, not used it before. Much tidier. The cooling fan is nice and quiet.

    Great price
    Great product, comes with everything you need for modern parts and expandability, has 2 sets of 3 sata connectors and 1 set of 4 which saved me plugging in another sata cable if you have a fan hub that uses sata power.

    Prefer it over the RM650x

    Great, but be prepared
    It’s done me well so far. Just a heads up to people wanting to use a lot of RGB and newer pc parts. A 650W PSU will not serve you as well as a higher W will. Always go modular. Always decide on a higher wattage if you’re going to be using very high end parts. These PSUs can last you up to 10 years so spending more on a higher wattage may save you a hefty amount in the future.

    Bought from Amazon warehouse as used-like new. It had obviously been installed at some point but it was 50 lower than a new one at the time so I went with it.

    Worka as expected!
    This PSU would be enough for most builds, be it small builds that use 1650ti or less and even bigger ones that use 2070 or 2080 cards (or equivalents).

    It is very easy to fit inside the tower as I set up some cables before fitting and other cables after fitting it inside. I have been using it for months now and I never encountered an issue with it.

    Does exactly what I needed it for. Absolutely no issues with it. For a power supply it’s definitely worth buying from a trusted brand like Corsair, not some cheap make. All the cables are black which is a nice bonus, no ugly yellow or green cables!

    Golden Review Award: 2 From Our UsersIt is what it is
    I didn’t realise I ordered the RM850 and not the RM850X.

    If I could go back I’d go for the latter, that’s not to take anything away from the RM850 as it does exactly what it says on the tin.

    No issues thus far, but I read that the components in the RM850X are slightly better and it comes better packaged with braided sleeves on all cables as opposed to just the ATX 24 pin.

    Golden Review Award: 2 From Our UsersThe best PSU for a midrange PC!
    Got this as a replacement for my Cooler Master MWE550 which was failing at just 1 year of serving. Absolutely perfect! Solved all my problems plus gave me extra room to overclock my GPU. 650W and 80+ Gold Rating helps in more efficiency. Cabinet didn’t have enough headroom for the PSU’s wires because of my cabinet having a separate PSU shroud but it’s the problem with the cabinet. Everything ran smoother. Fixed my random shutdowns caused by the old faulty PSU. Will be the best PSU if you have a midrange spec PC like mine.

    My Specs:
    Core i5 9400F
    GeForce RTX 2060
    ROG B365-F Gaming Motherboard
    2+1TB HDD + 240GB M.2 SATA SSD
    Dual Monitor setup + Drawing tablet
    5 RGB case fans
    AIO Water Cooler for the Processor
    And of course, this amazing PSU.

    Highly recommended. Will update if anything happens with this.

    I'm powering a beast of a PC with this and it works well and provides stable power. Installation was painful though as it has extremely stiff wires and once inserted into the slots, they're difficult to take out, so only 4 stars instead of 5. It thankfully came with a bunch of cable ties which was nice.

    This was recommended by a local PC store, and it provides enough connectors for what I need. I like the fact that the fan doesn’t spin when it doesn’t need to produce as much power. Sadly it is shut away inside the case, but it does the job.

    What more could you want?
    Due to in being modular it makes installing it an absolute breeze! Also means connecting everything to the mobo is a lot easier instead of having to stretch a specific wire to that hard to reach spot.
    Can’t hear it running, it runs silently (either that or my other fans drown it out).
    at 750w I have plenty of room for overclocking/upgrading for the next few years.
    All in all, a top drawer psu.

    This thing has enough power and connectivity as power a star ship. I maybe missed a trick though and maybe should have got the 850i (or the nearest model to that) as it allows monitoring various aspects of it’s performance. I didn’t know that at the time though so my bad for not doing my research.

    Golden Review Award: 3 From Our UsersExpensive but powerful and stable. Cables could be bette
    It looks like a PSU and acts like one, so that’s a decent start. I don’t suppose there is a lot you can say about how a PSU is presented other than the cables that are supplied.
    A fully modular PSU, the RM850 is supplied with a plethora of cables for Motherboard, CPU, GPU, SATA and Molex power connections.
    There are enough for pretty much any application but the cables are also why I knocked a star off. They look cheap and at this price, they shouldn’t. Most, with the exception of the mainboard 24v cable, which has a braided sleeve, all others are “ribbon” flat types that look terrible and are quite hard to hide for cable discipline. You’d think being flat they would be easy but if they twist they stick out.
    I have an EVGA G3 in my other system and it’s all sleeved cables and they look much better and more “premium”.
    IF Corsair sort this the whole package is a winner in my book. Until then, it’s 4 starts overall as it does cheapen an otherwise expensive PSU.

    Great PSU for the money
    Delivery was when expected. The part was easy to install and the cables included are really good quality. The modular design mean you only have to use what cables you need so you can save space and improve airflow. All round great build quality for a reasonable price.

    Good one
    It’s great, although it has to pass enough time to really tell. But it looks like it will be a reliable product.

    Excellent seller.
    Seller was outstanding. Having purchased the PSU discovered that the problem was with the graphics card. Returned for refund. No probs.

    Good quality and performance
    A good quality PSU. I reccomend it if you want to chip off a few pounds on the cost of the PSU. It might not have the fancy cable pouch but you buy for the performance and it does do the job properly. Easy to assamble and has enought ports for all your needs if you are planning a mid to high end PC.

    A great power supply
    I haven’t heard this power supply once. It’s easy to install and the modularity of it makes cable management a walk in the park. Gold standard too.

    Great quality PSU
    I bought this product as an upgrade from my Corsair vs450 as I got a more power hungry GPU. Works well and was easy to install and my overall temps decreased which was a plus!

    Works great.
    Great Packaging and good amount of cables. Was upgrading from CX550m and had no issues what so ever.

    Always my first choice.
    Quality, reliability. I always buy RM 750/850s. Instructions could cause slight confusion over cabling for beginners but overall happy and expect it to run quietly in a server for next 6 years or more.

    Corsair quality as always
    Everything you expect from Corsair, pure quality, never once had an issue with any of my Corsair components. My only issue is that all psu’s Should come with sleeved cables or the rubber cables so you can choose which ever you prefer.

    Fantastic quiet and efficient PSU
    Great PSU, the modular design really allows for a cleaner build. The noise levels are incredibly low when the system isn’t being pushed – I even needed to check the fan did spin up as it was so quiet!

    I’ve used multiple Corsair PSU’s in the past but this one is a league apart. Well worth the investment.
