Customer Ratings & Reviews

My several year old Corsair RM850 was having issues and was time to be replaced. Went to Best Buy to see what they had for 850 PS and this was it. The upgrade is well worth it. The old RM850 was bronze rated, the new RM850x is platinum rated. It is doing a great job and giving plenty of power to my PC with no issues. Powers 3 SSD drives, a regular drive, 2 high end webcams, a Blue Yeti X mic, wired headset, gaming keyboard and mouse, 1070 video card and the rest of the PC including a radiator cooling system with no issues. Also use the PC to keep my phone at full charge. Is always on and have seen no issues so far. Fairly easy to swap out. Very nice cables and as a bonus extra comes with a nice little velcro closure bag for storage of extra cables.

This is currently powering a older i7 that is power hungry! Works just like it should. The cables are much better on this model versus the CM series. Plus its modular!! Cant go wrong with Corsair! Been using their products for years.

I'm quite happy with this PSU in my new monster rig, it has the additional 4 pin power that my newer Motherboard needs and many of the newer power supplies are omitting. The full modular connections are great for cable management too.

I upgraded my PSU to this one. Worked great no problems. Has plenty of power for future upgrades ie: graphics cards. This unit is fully modular so no unnecessary cables needed for easy cable management.

This is more than enough power for my RTX 2070 super GPU. If I ever need to do any over clocking, I'll have enough power to do so. This PSU is fully modular, which helped a ton because I only used the cables that were needed.

This power supply is sleek and powerful. It has the wattage to run pry much anything you throw at it. It also has plenty of slots available to connect all of the components you want. It comes with a bunch of cables, which it great!

Like all corsair PSU's, it's a fantastic device. Very easy to work with and the modular cables are great. Able to power a 3070 in my girlfriends PC with no issue. If you're looking for a quality basic PSU, this is it.

I've been running this PSU for a couple of years now and have no problems whatsoever. This is a super high quality unit and the fan is inaudible. It comes with a nice bag/case and a case for the spare cables. Highly recommended.

REALLY Easy installation and good instructions. Especially nice modular design and comes with more than adequate number of cables for motherboard, pcie boards, graphic cards, sata connections, and other accessories. Good job Corsair.

It is powerful and efficient. More than enough for the best gaming systems and modular for great electrical efficiency and no extra unneeded wires in your case. Software available that can monitor efficiency and heat. Best technology for a great gaming system.

Great power supply that I purchased so I could use a 2080ti. So far it has been great and has not cause a single issue. Modular and easy to setup, can’t go wrong. Should work with the new 3000 series from Nvidia as well

I needed a much larger power supply to support my new Asus Motherboard, i9 Processor, and RTX 2080 ti Ultra graphics card and this delivers exactly what is needed. Corsair makes amazing products that you can depend on to get the job done every time!

This Corsair Power Supply is one of the best among my power supply units I have been used. The fan is very quiet, it comes with shielded cables for PICE and CPU. This is 80 plus gold, so it saves energy.

The RM750x set the stage for this purchase. My AMD build is rocking that and with these new GPUs recommending 750W PSUs and pulling down 500-600W this is a safe bet for the next few generations! Super quiet as well

I have the following parts in my PC. CPU - Ryzen 7 3800x @ 4.5Ghz on all cores RAM - 2x16GB DDR4 3600 Storage - 1 x 256GB WD Black SSD, 1 x 1T Samsung Evo Plus SSD, 1 x 4TB Seagate Baracuda HD GPU - EVGA 2080 Super XC Ultra This PSU supplies all the power I need and will be great for when the new PGUs are released at the end of the year. I am going to buy the fastest GPU for VR when the 3080ti and AMD Big Navi cards release. Once I see the benchmarks and know what's the best for VR I will be buying that card.

Power supplies really haven't changed much in the last 10 years, but finally, this is a real game changer. Pros: - Completely silent, even under load - Fully modular-ness makes install/reinstall/removal a breeze - Fantastic for mini cases - Ultra short cables Cons: - Cables should be all loose, instead of ribbonized for maximum flexibility - SATA power should have both 90º and 180º options, instead of just 90º - Should have come with SFX to ATX adapter In the month I've used it so far, it's been nothing short of amazing. This, paired with the SG13 was the best machine I've ever built. Opted to get the Silverstone PP08 adapter for extra ventilation.

Excellent product and customer service! Bought this and Corsair actually chose to RMA my old P/S that I did not expect to be covered by warranty! The modular nature simplifies installation and it is quiet.

Bought this when upgrading to a Ryzen cpu. Modular is the way to go. No extra cables to hide, use only what you need. Had all needed connections. Simple, easy, and works great. Has a quite mode, and i never hear the fan on this.

Got this for my latest Gaming rig. Its not cheap but if you are spending 1200+ on high end components get something really reliable. Japanese components, 10 year warranty, silent operation. Plenty of power and modular

You can never go wrong with a power supply from Corsair. This is the most quietest power supply I ever had and has really nice cables. It even comes with 10 year warranty which another plus!
