Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (Low Noise, Zero RPM Fan Mode, 105°C Capacitors, Fully Modular Cables, Compact Size) Black

Bought this after I had a PSU fail on me because I heard from friends and other reviews that Corsair PSUs were super reliable. They were right. I've had 0 problems. The cables are great, never had a power issue. Would recommend to anyone looking for a PSU.

You’ll most likely be getting the newer 2024 model, not the older 2018 version, so it’s worth checking other RM850x listings, you’ll find it priced more competitively there. This particular listing should be updated to avoid confusion, since the older model is no longer being produced or sold. That said, the RM850x is an excellent PSU: reliable, efficient, & quiet. It’s just not worth paying an inflated price here when you can purchase the same unit for less elsewhere.

Bought this to replace an old 650x corsair PS I had in my last build for the current rig. That power supply lasted nearly 11 years people! Sure it was older and not modular as that wasn't a thing - but 11 years? My system is centered around corsair from the cpu cooler, ram, fans, pc case, mouse pad and psu. Everything runs flawlessly, simple to install with a focus on aesthetics and the cable management is insane - especially with that 5000d case. 850x is more than I require, but this is also future proofing as I intend to be using this psu for a decade or so. Its fully modular, meaning you can only attach the wires you need, which eases the strain of the cable management chaos. I have 4 cables attached to power the cpu, gpu, sata sdd backups and of course all the rgb modules on the back panel). Great, quiet and modular psu backed by Corsairs legendary quality.

I purchased this PSU as an upgrade from the factory unit in my Dell Optiplex 7010 MT. If you are looking to put one of these in this same type of PC, a word of warning: this PSU barely fits. I thought I would actually have to return it, but I was able to squeeze it in while sliding the side panel latch forward. Luckily, the latch still moves back enough to allow the side panel to stay closed, but the latch does rest against the PSU. Aside from that, I really like this PSU. The cables are a bit stiff, as some have stated, but I found that they hold bends really well because of that. This is definitely suited for a larger case, given the size of the unit and the actual cables. It was a tight fit to route the cables around some of the hard drives in my mid tower. At normal load, the fan doesn't run at all. Until I put a GPU into the PC, I don't think I will ever see the fan spin up. One of the reasons I opted for this unit is because of how many SATA cables it has. If you are building a media server, it's a great option since you can attach plenty of drives to it. Overall, I would definitely recommend this PSU.

GENERAL INFORMATION As with all Corsair products, this power supply turned out to be a wonderful buy from a name brand - especially if you can snag it when it's on sale for just $90. PROS - Very limited noise level - almost completely silent - Doesn't crash/fail like cheap alternatives - Looks great in all-black PC builds, if visible - Built in cables are well designed - the SATA cables, for example, have multiple connectors on one cable to allow for insanely easy chaining. - Labeled cables. Sometimes, non-labeled cables can be hard to find where to place in your PC. These ones are clearly labeled: PCIE, CPU, SATA, etc. CONS - The price. It's a really nice price when on sale, but when not on sale, you can find some cheaper alternatives from non name brand companies. However, as this is a power supply, you should NOT cheap out on it. CONCLUSION I think this power supply nailed the job. It's a great supply for my computer with a 3070ti and 5800x. Really proud of this one.

Good power supply that works well with high end components (Ryzen 5950X with a RTX 3080). Under load, my power pull hit 750 watts sustained and the PSU had no problems handling it. The PSU doesn't make much noise and was easy to install. My only complaint with this power supply was with the provided power cable. Rather than providing a 3 pin grounded power cable, a 2 pin power cable with a grounding wire was provided (picture provided). Not really a problem since I have lots of 3 pin power cables, but why include such a specialized cable that won't work with most household outlets. If someone were to make the mistake of using this cable on a standard household plug and didn't connect the ground wire, it would present a fire hazard. There are a lot of reviews stating that the power supply stopped working or burned out components on their motherboard. I suspect that this may be the reason.

I want to make this quick so let me just clear some things very quick, my rig has never come near to using the full 850 watts, so I wouldn’t know how it performs under heavy work loads. Also, I live in Cali, so temps are around 75-85 here on average, so I don’t know how it performs in really hot environments. Now, that being out of the way, I wanted to say this is a great PSU. For one, I’ve owned it for about 4 years and haven’t had any noise complaints because it’s very quiet. This next part is VERY IMPORTANT to me and should be for you as well. About 5 months ago, my PSU began having problems and would randomly shut off, I contacted customer support and let them know, they replied fairly quickly and were nice. I got my replacement in about 3 days and that was that.. TLDR: - low noise levels -great customer support -good power efficiency

RM650x, 750x, 850x, SF600, SF1000, the PSUs for my current builds. Without a doubt, the RMX Series will protect and deliver clean power to your investment. Don't be builder that loses a system to a cheap PSU. With a 10 year warranty, you know the RMX was built to last. I say go one step further, and protect it all with a decent battery back up (UPS).

The Corsair RMX series is very good for people that are serious about overclocking and there are lots of tests that prove it. I, however, am a lighter user and just care that the power supply performs reliably and the RM650x has not let me down. Another major factor for my purchase was the 10 year warranty that came with it, giving me peace of mind for my current PC build and any upgrades/rebuilds I end up doing for the next decade. Furthermore the 80+ Gold certification is a great thing to see. There are cheaper power supplies but with the features and reliability that the RM650x offers I say its worth the investment.

LLevo con ella 2 años, funcionando sin problema, me siento protegido, actualmente tengo una 3060ti y todo super bien

Corsair isn't what I'd call an old school PSU vendor, but damn have they ever proven they're here to stay. My favourite PSUs back in the day were OCZ and PC Power & Cooling. They were my go-to vendors but sadly neither exists anymore the way they used to. Since then I've been using Corsair PSUs and I couldn't be happier with their performance. I have a Corsair HX850 as my original modular PSU, so when I went to build my new PC I picked up this RM850x model. It's fully modular, it's whisper quiet, it isn't too long, and it has all of the connections you could want. But what sets this unit apart is that it comes with TWO CPU connectors! So you can hook it up to a motherboard with an 8pin and 4pin connector for the CPU. If you're doing any serious overclocking with an i9 or Ryzen 3900+ this is absolutely the PSU for you. The only thing I don't like is how the connectors have this extremely stiff wrap near the actual plug ends. While you can still do a clean cable build in a case, these stupid stiff wraps will prevent you from being able to twist or curl the cables so that they aren't sticking straight to the side for a couple inches before going back to being a regular cable. Why they chose these stupid wraps I'll never be able to guess, but they unfortunately exist. If you're using the stock cables this unit is a 9/10, with the point loss for those ridiculous stiff wraps. But if you're going to use cable extensions or aftermarket cables then this unit is easily a full 10/10.
