RMx Series: The reliable, high-performance, 100% modular power supply by Corsair


TheCorsair RM650x 80PLUS Gold power supply features 100% modular cabling and an energy-efficient "80PLUS GOLD" certification rating. It delivers reliable power with minimal losses. Its comprehensive cabling and high power output make it easy to assemble the PC of your dreams.

TheCorsair RM650x PS U is quiet thanks to a 135mm thermo-regulated fan. Thanks to the fan's Zero-RPM mode , the power supply runs completely quiet when not in use.


A first-class power supply

Reliable, quiet, modular, powerful, efficient - theCorsair RM650x power supply has it all. With 80PLUS Gold certification, a 10-year warranty, and carefully selected components, you can be sure that your setup will be reliable.

The RMx series power supplies feature carefully selected capacitors and transformers to eliminate coil squeal and other background noise that can be annoying in quiet environments.


Quiet and efficient

The Corsair RMx power supply is designed to minimize excess heat, so the fan doesn't even need to run when the PSU is at low to medium power. When it is under heavy load the 135mm fan takes over in near silence thanks to its optimised blades.

With80 PLUS Gold certification, theCorsair RMx Series power supply allows you to reduce your electricity bill while ensuring stable voltages and continuous power to your entire system. It's ideal for maximizing the life of all your components.


Fully modular power supply

The Corsair RMx Series power supply isfully modular, allowing for quick and easy assembly. You can use only the cables you need, and leave the rest in the box for future upgrades. Your power supply is upgradeable!

Its modular cables are black and flat, with a low profile, for an enclosure with optimised airflow and a clean, crisp look. They are essential for all cases with windows giving a full view of your configuration.

    Config Gaming

    It does its job as a power supply in a pleasant silence.
    I bought it to power a not very demanding gaming configuration, but what a surprise to see that this power supply is only supplied with 1 EPS/ATX12V 8 pin cable for the processor power supply whereas my motherboard requires an 8 pin cable and an additional 4 pin cable for overclocking (Asus Rog Strix B550-F Gaming card). I'm not sure if this is a good idea or not, but I'm not sure if it is. The cables are too reinforced at the level of the connectors which can quickly become an ordeal to make a correct management cable because it is difficult to bend them correctly so I ended up buying a Pro kit of cable for power supply with individual sheathing of type 4 at 100€ to complete this already expensive power supply. I'm not sure if this is a good idea or not, but I'm sure it's a good idea to buy a power supply that's not a good idea, so I'm not sure if it's a good idea to buy a power supply that's not a good idea.

    Good quality but limited number of connectors

    Hello,
    You can't hear it, the packaging is of good quality and there is a 10 year manufacturer's warranty.
    Attention, we do not find the detailed documentation on the site of the manufacturer (only paper version in the package).
    There are only 3 EPS12V or PciE outputs.
    My motherboard bought on a site of the LDLC group (MSI MPEG UNIFY) requires 2 EPS12V power connectors and only one is delivered with this power supply. So I had to buy a second one.
    There is only one connector left to power the graphics card. I might have to change my power supply if I want to upgrade to an RTX3000. Corsaire is developing a 12-pin cable that connects to two 8-pin ports on the power supply.
    Unless you can connect the RTX3000 to just one connector on the power supply and use the 2 connectors on the PCIe cable to connect to the adapter provided by Nvidia. Hopefully the power from one power supply connector is enough
    The same model in 750w has 1 more connector and comes with 2 EPS12V cables.
    I'm afraid I already regret my purchase, I hope not.

    modular and stable

    As usual, a reliable, modular, silent and stable privateer.

    I use RM850 for the house (double 2080Ti) but for the office pc's it's enough ^^

    Efficient and practical

    This power supply is a standard size, small enough to fit in my SL600M tower in vertical (an atypical tower with vertical airflow).

    There is a plethora of cables of various types, I do not regret this purchase.

    Quiet and modular

    Received this morning and immediately installed. Easy installation. No more superfluous cables in the box: thanks to the modularity. And above all: no noise! The last thing I needed to replace on my computer was a completely silent machine. It changes the way I work from home!

    Easy and practical

    Very good power supply, which is easy to install, and is also very quiet. Now I hope it will last me at least 10 years.

    Excellent feeding

    It's a very quiet modular power supply with a pocket for storing cables, small collars for attaching wires, 2 graphics cards, lots of sata and fan adapters. It also works perfectly, even when under load, so you can't hear it at all.

    A complete diet

    Very good, quiet and efficient power supply. The modularity is great, especially since the cables are thin and can be run more easily in narrow places. It is sufficient for my configuration (RTX 2080+i7-8700+4 SSD+1 SSD NVME+Ventirad+7 fans+2 DDR4 bars).
