Customer Ratings & Reviews

I generally have never had any problem with Corsair products. This power supply replaced my mothers from 2012. Yeah 2012. They're generally only supposed to last 7 to maybe 10 years and that thing was over 13 years old. Well her original power supply which was an ATX one from like 2011 or 12 and I think it was still okay but it was just so old that when I put my computer parts in it from 8 years ago it demanded more power and I didn't want to have it. Underpowered so I got her about 100 maybe 200 w more than she needed just in case he needs more power later on. Overall Corsair products are great products until you need customer service. I bought a power supply a 1200 w one and it's supposed to come with two pcie cables for the graphic cards. For some reason it was a mistake in the box and it was only one in there and most gpus nowadays are so overpowered to use three plugs back in the day. Corsair used to give you more than what you needed back in the day they used to use two, so they'd give you like four or even five. This one didn't even give you enough for a High-End graphic card which uses three plugs. The mid-range ones use two so you know you always got to give a spare even when you're buying a piece of furniture. They always give you at least one or two extra screws in case one of them gets stripped or they break and you know and then they give you dual PCI Express adapters which can become unstable and where two plugs plug into one power unit and it's just not a safe thing to use. Most of the friends that I have never use those cuz they say they can be unstable they can heat up. One said they had theirs melt. It's just not safe. You need three separate pcie cables, not two combined into one so I said why did you even include those? If you're going to include one and give us extra pcie cables, it took them over a month. Numerous mistakes. Then they sent me four PCIE dual cables and I'm like that's not what I asked for. In fact I said specifically don't send me these for one reason or another and that's what they did the first time and it wasn't even the ones that came in my power supply after are going back and forth with them for over a month. I said look send me exactly the same type the flat pcie cables separate ones not dual the exact same ones that come with my power supply do not deviate from it. Donami send me braided one send me the exact same ones that came at my power supply with the exact same part numbers that are on the cables and after over a month of arguing back and forth they finally sent me the correct cables and four of them. That's my only reason. Wife of four star is out of five. You know if you don't have any problems with the products which I think 90 to 95% of the time you won't and there's no issues then you generally don't have to worry about their product cuz I have some quality products there. Just make sure that when you're buying a power supply you buy a little leeway in case you get more energy demanding parts like gpus. So if you think you need a thousand get 1200 if you think you need $750, then get a 850 or $1,000. Always get a little more than what you need for a little leeway just in case and that's what I've always done since 1999. The price was good also on this product because it was on sale and it was less expensive than going to a competitor. So the timing was perfect that this was on sale cuz she needed it. Hers was so old I wasn't going to take a chance on it even if it did last another couple of years. It was well past its prime so I got her on new modular one so I didn't need all the extra cables that the old one had. That's how old it was

Works perfectly and is able to fully power a 5070 GPU or any you might have in your PC. The ability to dial the fan as well or just have it function on automatic is a really nice feature.

Had this PSU for about a little over a month now and it performs extremely well. I was a little worried about the heat output, but the adjustable fan control is a nice addition to help you maintain lower temps woth higher loads. That being said, I typically keep the dial in the "off" position that way the auto fan control takes over and I can keep noise to a minimum. Overall. Very solid purchase and Corsair continues to impress

This is a good PSU made by a good PSU company. It is ATX 3.1 compliant, which means it will come with the necessary bits to hook up your shiny new graphics card without popping the cable (provided the user plugs everything in correctly). Solid form factor, generous cable lengths, basically everything you would expect from a good PSU purchase.

So far, so good. I've used Corsair power supplies in the past and had good luck with them. I was happy to see the size of the fan as the larger fan is much quieter. The build that I used this in for reference is an asus main board with a Ryzen 7 9700x paired with an rtx 3080. I was able to add 7 140mm fans to the case for good airflow. Result is a system that is very quite and is really only noticable when gaming, and even then not as loud as the PC my son has. Overall I'm happy with the power supply and would recommend. If you want to run more than a single video card you may need a larger power supply. There are websites that you can use to virtually build your system and get an idea whether it will adequately support your planned system to both number of connections and wattage wise. A word of warning though for modular power supplies. Bag and tag your extra cables and mark for power supply. Some older Corsair cables that fit the slots are wired differently and can fry equipment if you use them

Awesome PSU. very quiet, runs cool, and no problems at all curing set up or during operation.

Love it. It is a lot quieter then my old one. I love how I can adjust the speed

Works great . Easy install for a new pc builder! Modular so you use what you need. Good fir cable management!

so easy to install! and cut out having to use a lot of unnecessary wires!

Great PSU after doing research I found this was a highly rated power supply. I really like the adjustable fan knob I put it at lowest setting so it's always running. It's replacing only a 3 year old EVGA PSU that went bad and was causing my PC to crash. After I installed the Corsair no more crashes!

Quiet, easy to install, no issues and best of all; it works

Easy to install and fully modular, easy for anyone who hasn’t installed a modular before.

Very nice power supply rates extremely well for protection on your computer from brown outs and consistency. 850w is more than I'll ever need. Corsair is a great company that stands behind their product as well. I had an old version that I had to RMA it was 6 years old and no question asked they sent a replacement. I really like this brand

Great PSU. The manual fan knob is an interesting feature but if placement of the tower doeant make that accessible, its not very usable. The cable management is great with the fully modular design. Very quiet as well.

I have been a corsair power supply guy for several years now. I was initially a EVGA guy but made the jump over and so far haven't gone wrong. I end up buying this unit for the new nvidia power connection. Stored the previous RM850e I had as a backup or for when I upgrade the wife pc in the future. This power supply is powering a 7800x3d, 32gb of ddr5 on a Asus B650e board, asus tuf 5700ti and all the other usual stuff.

ATX 3.1 power standard from Intel, RMx PSUs have the connections needed to power today’s demanding PC hardware including a native 12V-2x6 connector. 100% Japanese 105°C-rated electrolytic capacitors deliver fantastic electrical performance, while a 140mm FDB fan provides low noise cooling. Backed by a ten-year warranty, RMx PSUs are the gold standard for many years to come.

Got this unit for a new PC build. I have used Corsair products before and never had any issues. This new power supply is great as it is totally modular and you can use only the cables that you need leading to a cleaner look and easier cable management. Would definitely buy again.

Very nice PSU. Like the nicely finished cables with separators. Had a little "new" smell with first use under power, but that went away quickly. All in all, I can recommend this PSU.

Was having trouble with my desk top crashing all the time. Then i bought a new graphics card and had Bestbuy install it. They advised me I needed a new power supply unit to support the new graphics card. I agreed it was necessary to run my new Cinema 4d app. They installed itand I have not had a single crash since that. Very happy guy today

This thing is a beast. It is crucial for my pc, which is fully decked out with Corsair. I have 10 Corsair fans, 128 GB of Corsair RAM, and a Corsair AIO cooler. Other Corsair peripherals that I have are a Corsair XL Extended mouse pad, a Corsair wireless charging pad, which is used to charge my Corsair mouse! This PSU is a must-have!! Try it out for yourself! Corsair never disappoints!
