What can be said about the RMx series? This is another solid mid-range entry from Corsair that's sure to last the life of your PC. If not, it's backed by one of the best warranty's in the business. No issues getting up and running in a few minutes, cables were strong, but flexible. I'm still a little annoyed Corsair doesn't include all braided cables, but those are easy enough to replace if you want to go for that super-clean look. The power supply fired up and performed perfectly at idle and under load, no issues with whining caps, noise in the power line, or other issues some mid-range PSU's tend to exhibit. If Corsair built this thing to a price point, it certainly doesn't show. Bottom line, if I could give an extra half Egg to the RM-750x, I absolutely would - ... MoreWhat can be said about the RMx series?

I subtracted one Egg for the lack of all braided cables, and the lack of that fan test button which, in my opinion, should be mandatory for any PSU with a zero RPM fan mode! At the end of the day this PSU breathed new life into an old HTPC for me, and the PSU will likely out-last all of the components in the machine.

I have been a Corsair fanboy for years. They make good stuff. I have NEVER had one of their products fail me. A decent power supply is critical to the reliability and stability of the entire system…you don’t want to skimp here. Install and function went just fine…and I really love the modular power cable design…so much cleaner and easier to route through your case!

Out of all the failures I have had, the PS is the most frequent, followed by hard drives, Logitech wireless mice and un-maintained water cooling systems. You never know when they are going to fail. I personally have never had a PS fail on day 1, but I have seen anywhere from 1 month to 2 years. The ones I have seen go, go up in flames!... well at least sparks and burny smells. I always worry it might burn the house down if I am not there, and usually I am not. Some have just degraded to the point of causing strange behavior – which is really hard to troubleshoot. The few I have diagnosed turned out to be due to capacitors, usually bulging, but sometimes exploded. If this model’s “Japanese capacitors” are truly better, then I will be happy.

If any PS makes it beyond two years in your exact same rig, you are probably good to go for a very long time. Since I don’t like down time, my approach to sizing the PS is to ensure my most likely point of failure can handle the peak load without breaking a sweat. That means not driving the whole or any components anywhere close to their limits. That is why I add +50% to +100% capacity to my calculated power draw to size the PS. Yes, that is right – double the capacity! Everything runs cool, quiet, more efficiently and in the mid-range of each components electrical and temperature specifications. This might cost you an extra $30 - $100 (maybe more on the super high end), but you will make some of that up in efficiency, come out way ahead when you don’t have to suffer down time and heaven forbid the rare case of burning the house down. 750W should be plenty for your average gaming rig with one decent video card. There are two PCIe cables, each with two connectors. Probably more cable than needed. Based on what I just laid out, driving multiple high-end video cards will likely lead to early failure of any 750W supply. Who knows, maybe this one is different. I gave it 4 eggs only because it has only been installed for 3 weeks. I will upgrade to 5 if it makes it to a year. Update (3/25/19) - Still working great. No complaints.

Used it in my build with a 3080 and an i5 12600KF. Works perfectly. Had previously purchased a 750 MSI PSU I from another store and the thing worked for 5 minutes before dying. Got refunded for that one. Absolutely no issue with this corsair 750 PSU. Would highly recommend.Scan delivered within 2 days so it was great that I didn't have to wait too long to get the build finished.
Received this Corsair RM750x Power Supply Model # CP-9020179-NA for review. The PSU arrived undamaged and well packaged. Like all power supplies installation is fast 4 screws and a Phillips head screw driver you are mounted. Unlike most power supplies this is fully modular. Meaning all cables can be removed, where as in semi modular the 24 pin power cable is still hard wired in. This allows for much easier PC building. Having over 20+ years of PC building fully modular are by far easiest for cable running. Planning and making a clean interior is just easier when you can control each individual cable. This power supply is very quiet under operation. I loaded it to one of my PCs that has an 8700k at 5.2 ghz, 2 GTX 1080’s, 3 SSD, 4 Hard Drives, 5 case fans, and a ... MoreReceived this Corsair RM750x Power Supply Model # CP-9020179-NA for review.

Having over 20+ years of PC building fully modular are by far easiest for cable running. Planning and making a clean interior is just easier when you can control each individual cable. This power supply is very quiet under operation. I loaded it to one of my PCs that has an 8700k at 5.2 ghz, 2 GTX 1080’s, 3 SSD, 4 Hard Drives, 5 case fans, and a Corsair AIO liquid Cooler. Under max 100% load during torture tests the system pulls upwards of 735w from the wall and this power supply had no issues supplying power while under an 8 hour loop. It’s also been powering the same system now for 3 weeks with no issues. Without a load tester, it’s hard to know quantitively how much can I push this unit before failure. But being within 15w of its max rated loaded for hours with no issues helps give me peace of mind. I’ve been using Corsair PSU for a long time, and have been happy with every single one. Why do I use Corsair PSUs in all my builds for myself, friends, and family is an easy question to answer. Back in 2006 my then just over a year old AMD Duel Core 4800+ socket 939 build started to act up. Random FPS drops in CS:S, random stability issues such as reboots with no real source. Mind you this wasn’t an overclocked system. I checked the common things, fresh install of windows, new hard drive, new video card. One day a few capacitors in my motherboard blew. So I attributed all my errors to “o my motherboard was just bad all this time”. Replaced the motherboard, and guess what all my stability issues were still there. So I ripped the entire build apart. Upon checking the PSU from an a company I won’t name and shame, with a flash light I noticed one of the caps that was visible on the PSU were bulged. I took apart the PSU and guess what 2 smaller caps and one main were all blown. This was PSU that was 300w higher than what I needed, and it wasn’t cheap. So one bad PSU caused me many weeks of issues that were a pain to track down. This is where the Corsair RM750x comes into play. If you are going to spend hundreds to thousands dollars+ on a build, do yourself a favor a buy a quality PSU. It’s the one component you don’t want to cheap out on. This model you get a nice quiet, cool, high efficiency without breaking the bank. It’s backed by a huge 10 year warranty. That’s peace of mind that only a great track record based on reliability can provide. As someone who has worked on (repair/upgrade etc)over 1000+ PCs and built over 140+PCs buy quality parts it just makes things easier over the long run.
Ordered this product and a month later it stopped working. Was granted a replacement by Newegg, wasn't able to put it in for a while do to moving and other life issues. So it stayed in the box for a while. Finally got to install it 2 months ago. Shut my computer down last night, and now it will not turn back on. No signs of power at all. Computer is plugged into a surge protector and everything else that is plugged into it still works. After 2 months of barely any use the power supply is yet again dead, and now its way past the timeframe of being able to return it. Now I have no computer for my work, and I am out the money wasted on a terrible product.
Just bought this PSU closing in on 4 weeks. No reason to think it will not perform well. Here is why only 3 sparkles... The cables are very very stiff. Okay, I get it... Don't like them... spend more money! So to make the case look neat, I bought an extension kit from micro connect. Guess what? My ATX connection on the PSU is a 20 type 4 split. And you can't easily find those unless you buy it from.... Yep, Corsair aaaand its going to cost ya no small fee! Aaaand it's JUST the ATX cable!!! (not a kit)Needless to say... No more Corsair for me! Not a good first time experience

This is my 4th Corsair unit, the 550W unit is still in my HTPC (4690K and an assorted of components to watch 4K content), with somewhat everyday use. Previously this 9900KF had a Rosewill unit which is a 650W, plenty good but given the circumstances the Corsair is a better choice overall, considering that it comes with two CPU 8pin power connectors. I definitely recommend Corsair power supplies, the in-line resistors give me that peace of mind the unit could not damage any core component. Just make sure to save the plastic bag to store the extra cables. Although I like the cutouts, obviously more air-slow.
First off, if you haven't seen it yet, check out the PSU Tier List guide online. You'll find that experts have rated this PSU one of the best ones out there. The 650W version has served me flawlessly for years. When I upgraded to the 750W version, it actually only lasted me a day before suddenly not providing enough power to turn on my system. I trust this series so much that instead of getting a different PSU, I swapped this for another RM750x using Micro Center's awesome exchange policy. No issues whatsoever with the new one, or with Micro Center's service. Only docked a star because of the one-off dud PSU, but the exchange went so flawlessly and effortlessly that I would really give this 4.5 if I could.
It does the job, and is very stable supplying current where other cheaper brands may fluctuate slightly in the past I owned.Check your requirements but this should also be able to drive any single or dual graphics cards setups easily. Really, you don't need over the top 1000 watt supplies these days unless you have very good reason. I have 5 drives and, lots of USB devices, a single GPU Nvidia GTC 970 and 8700K mobo, and it gets not even close to maxing out under load. ( < 50%) but there is no harm having a bit of overhead, I have plenty here to to allow for a heavy duty SLI or crossfire setup should I want in future. as it is for what I use a 400 - 500 watt supply would have been plenty.Don't worry if the fan does not come on, it will only do so under load if ... MoreIt does the job, and is very stable supplying current where other cheaper brands may fluctuate slightly in the past I owned.Check your requirements but this should also be able to drive any single or dual graphics cards setups easily.

In any case it would have been a stretch. For the very obsessed cable management with large tower cases this may not be desirable, so I had it go over the top to avoid the extra stress (pull)) on the motherboard, that's okay by me. Corsair could have added a bit length here. OTOH the longer 2 x 4+4-pin CPU cable could reach neatly through the back of the case with a bit of room to spare.Other than that there are plenty SATA connectors and more than likely will contain everything you need, hopefully this should last a long time to replace my Silverstone which lasted 8 years. Obviously only longer term will tell how good the quality is, but it seems well build and is nice and is quiet.
