I used this to replace another PSU which blew, and it was a huge upgrade. Noise levels are zero, and the cables look great and there are plenty of connectors so I doubt you’ll have any problem using this power supply
My partner’s original power supply finally kicked it after many years, so I’m impressed at how long these last, especially with the lack of up keep he did on his pc. It doesn’t have as many cables and connectors as my own psu but for his build it was ideal, making cable management alot easier than the mess of my own. Super easy and quick to fit back in to replace the old one.
Had a string of cheap Chinese power supplies last only a few months
So swopped to this branded unit and no problems so far after a few months
This one is 550 watt but its more heavy than the 800 watt cheap one I replaced it with
I`ve bought two of these so far. They seem to work well and are easy to fit in the average desktop system. the only thing to note is that the output wires are NOT colour-coded. They are all black. So you need to know what you are doing and take some care fitting it all together. Other than that, all seems fine. And the price was very reasonable.
No noise, i can hardly ever hear it. As easy to install as any power supply with 2 different 8 pins (6+2 and 4+4) and corsair is arguably the best brand you can get for a power supply. 15/15
Perfect little PSU for an APU rig. Low cost to operate, well built. Ran 3400g with vega 11 rig. 5600x with 6500xt and 5600x with rtx 3050 running fine also. Ran perfectly all three times I’ve bought this. No failures in any of them after two years.
Good value.
good psu for the money havent had a problem with it since installing the new one and yeetin the oldd one in the trash (where it belonged cheap crap psu)
Modular cables are great so no need for all the legacy connectors, ended up needing three of the four just because I have a couple of old drives and a gpu so saved a bit of clutter from the cables. Great value and as I mentioned you can barely hear it.
A direct replacement for a Corsair CX600 damaged by a power surge. It’s quieter than the original which was itself chosen for its low noise performance. Semi modular wiring made it much easier and tidier to fit. Ordered on a Saturday afternoon and delivered by lunchtime on Sunday! Highly recommended.
Having now used this for 2 years i can give a good review.
Its powering a 3600 with 16gb ddr4 and a 2060
I havent had any issues with ocp etc. I pretty much never turn my pc off so it has probably ran constantly for those 2 years and *touch wood* it has not failed me yet.
Sometimes i will have sporadic long gaming sessions and it handles it well even with a slight gpu overclock (i removed the overclock because the overclock was messing with some games which is no fault of the psu)
Overall to me an excellent budget power supply
Well let’s say I’ve had 2 other power supplys and this one by far has lasted the longest doing its job, the power delivery could be better but you get what you pay for, if anything I should have bought a seasonic as they are the best rateing on the market, but Corsair doing it’s job for now can’t complain!
I have given a 5 star for easy to install but in reality I had a friend install it for me – although he found it straight forward I feel you need some knowledge. The product itself has been working well for several months now on my old Dell computer and much cheaper than getting a new computer.
Always buying PC supplies as cheap, but good as possible! So when these popped up for 36.00 i nabbed one. Owned a few of these in the past and knew their quality. Unlike the Aerocool and gamemax cheap psus(also used a lot), these have a good heft to them and decent conponents for the dosh!
The cables are black sleeved as you can see in the photo which is great for maintaining aesthetics, although I’m not sure as to why corsair wouldn’t advertise this on the amazon listing and instead show ugly ketchup and mustard cables.
450w is enough for most (definitely not all) budget 1st 2nd and 3 gen ryzen 3 and 5 builds with graphics cards under the GTX 1660 super in terms of power draw (above this and you may want to consider more wattage or simply better quality with the CX/TM lineup). Always check your total system power draw with a service like PC part picker before building. Edit: on the amd side RX 570 is ideally the highest power drawing card you want to go with , an RX 580 should be fine but I wouldn’t reccomend it and neither does AMD.
Overall for the sale price of 23 that I paid this is a shockingly good deal. Time will tell how it holds up.
550W PSU, good while it was working. Unfortunately it failed. Done the paper clip test, the fan is spinning which according to Corsair means it’s working fine. Finally once I’ve plugged the other PSU everything was working fine, meaning something has gone wrong with Corsair 550W PSU.
Bought it in January 2018.
Good thing that it has 5 year warranty.
Just submitted an RMA replacement with Corsair, so will update once they reply.
A very solid, entry level PSU, Corsair make very reliable PSU’s in my experience, I always use them in my PC builds and everyone of them continues to to get the job done. I used the CV550 to power a budget gaming rig. I don’t believe that I’ve ever heard any of the Corsair PSU’s, certainly not over the case fans and CPU cooler, the fan inside them only activating occasionally. Solid, reliable performance.
For my first full build this PSU is great.
the modular connections means you can slim down mess in the case but if you do need to use them they are easy to install and uninstall.
The motherboard and processor connections arnt modular but that doesnt matter as you will always need them realistically.
its looks sleek and sturdy and runs silently.
Corsair are trusted and reliable which is what you are looking for in a PSU.
This is a review for the 450 W version (modular)
I’m not affiliated so I only speak from a hobbyist perspective
I’ve used this PSU twice. Once in 2017, and now in 2020 as well. You can trust a brand like crucial and I think it’s the best value for money. My philosophy is to save a buck and spend on a reliable PSU (like this one)
I can confirm it runs well with the following parts so far:
i54570s
i74790
Ryzen 5 3600
Nvidia GT1030
Nvidia GTX 1650
Nvidia GTX 1060 GB
…plus SSDs and RAM and bunch of coolers (7x Arctic 90 mm)
Being modular it’s a plus, saving you from cable clutter etc. The cables themselves are properly protected
So…for a low TDP system based on the above (don’t trust me and don’t PSU calculator before choosing a PSU), this is the one for me. It’s well balance between stability and power delivery, quiet, small to fit any standard ATX case, and hasn’t crashed (even while OCing the 1650)
I generally get the TX-M versions (550M, 650M) as for me they have been stable, relatively low-noise, and for the sytems I use them it more than sufficient (high-end CPU, medium GPU, SSD). But with the current lack of availability and higher-prices I took a chance on the CX-M.
The 450M is the lowest in the range but should still be fine for mid-end CPU/GPU and here I am using an APU (integrated graphics) thus more than sufficient. If you intend to use it in mATX or ITX system you’ll have to pay more for the semi-modular version – otherwise save some money and get the normal version.
It seems well constructed though lighter than a TX (albeit 550M) – still it supposed to use DC-DC conversion, rifle-bearing fan and decent (though not top-end) capacitors. It is only “Bronze” not “Gold” rated after all.
It does not seem to have the audible relay “clank” that the TX does on off/on. The fan seems to be similarly quiet at low-level utilisation, sadly no “off” or “eco” mode at this price – though generally higher-end PSUs only have it.
Personally, if you can spare the money and use a higher end GPU or overclocked CPU – I would say get the TX which should also last longer. For budget builds (but not cheap) the CX seems decent so far. Time will tell if it will last as long as a TX.
An excellent unit for anyone considering upgrading their build. I brought this for a computer assignment to upgrade my dad’s computer. It’s quiet and capable, and while not the highest spec it is certainly good value. The only downside is the number of cables – being a non-modular unit all the cables come attached and you cannot remove them. Not to worry, as it is a learning curve for next time. That said, I am confident this unit will contribute to giving my dad’s PC some extra life for some years yet!
This power supply came with clear instructions so that even a noob like me, building my first PC, was able to install it fairly easily. I’ve deducted 1 star because the SATA power cable that comes in the box is a 4 way splitter, which meant I wasn’t able to to connect my SSD drives and had to buy some extra SATA power extension cables. Maybe I was wrong to expect it to have all the cables I’d need, I don’t know.
Good, well designed hardware, which worked straight away without issue. The PSU is pretty quiet, looks smart and the modular design means you only need to install the cables needed, meaning you are not left with lots of loose ends dangling around inside the PC. Lots of cable ties also supplied, meaning you can keep things tidy in the case.
Only downsides are the lack of instructions provided (had to download from their website) and the SATA cables being a little short, meaning I had to use 2 rather than 1 to connect up my 3 devices.
On the whole, though, recommended.
Why are PC power supplies such crap? This is the 3rd power supply for my main system. They all claim to be ultra reliable, capacitors hand-rolled in Japan etc. and they all blow up after a few years. I hope this one is different.
When I installed this unit I started using the modular cables from the previous modular PSU (they were in the right place etc.). As soon as I connected any of these cables to the Corsair unit the PSU stopped – so it seems that you have to match the modular cables to the PSU. Not a big problem but worth knowing.
Got this today and went to install – but am now having to wait for an adapter.
One of the non-modular cables is a 20-pin motherboard connector. BUT if you have a Lenovo PC then it’s very likely you’ll need a 10-pin connection. As the 20-pin cable isn’t one of the modular parts, the only option is to try and find a 20-pin to 10-pin adapter, which will be anything from 3 to 10 depending on where you look and how quickly you want it.
Probably should have researched more and read more reviews, but this seemed like a good buy and I think most people would assume that, if a pretty well established brand such as Lenovo commonly use a 10-pin connection, that a leading PSU manufacturer would allow for that. Apparently not.
Apart from that, looks like a good quality PSU and comes with plenty of SATA connections, which is a big part of why I was upgrading.
So a good option but check your motherboard power connector first to avoid any frustration.
**Update after adapter received**
Unit was installed today and I have to say I was genuinely astounded by the noise reduction. When I first turned it on I thought I’d done something wrong, as I’m so used to a sub-standard PSU that roars into life when you turn it on.
This is effectively a silent-running PSU, and unless you’re right next to the unit with literally no other sound in the room, you’ll barely (if at all) notice it.
Installing the various elements was a fairly tricky business as the length of the cables for my system means there was a lot of excess that needed to be tucked out of the way, but the unit comes with some zip-ties to help with that.
Only real pain was that I am basically unable to use a couple of the SATA power connectors because the cables had to be twisted in such a way that I lose some of the reach.
But I still have some flexibility to continue upgrading my system, and can now do so knowing that the power needs will always be met for what I am planning, (with plenty of spare capacity to not be over-working it every time I play a game).
Definitely a recommended purchase from me, and one more star over my original rating – can’t give 5 because it was still frustrating having to wait for an adapter before it could be used.
Overview:
A well priced and well performing power supply for prebuilts, office computers or lower power draw gaming PCs. The horrors of the Corsair CX (GREEN) models aren’t to be confused as this is a well rated unit with 80+ Bronze efficiency.
I needed this for a R3 1200 | GTX 1050 system, with some headroom for a small upgrade; a higher end system would be better suited with a higher wattage unit in order to not stress the PSU and keep within the highest point of the 80+ specification – efficiency rating.
Advantages:
40, going budget doesn’t always mean a huge loss of quality or features
80+ Bronze Rated
Simple, not industrial and not ‘gamery’ aesthetic with a well fitting label.
Fan noise doesn’t stand out from either my Corsair AF 120 (Quiet Editions) or my AMD Ryzen Wraith Stealth cooler.
Disadvantages / Desired improvements:
One feature you do miss out on is modular cables (At least for the unit I got), and since the cables are wrapped and have some ‘heft’ to them cable management isn’t as much of a breeze as with modular units.
Whilst a low wattage unit, which also runs “cool” to “luke warm” from idle to full load; there is no ventilation on the front of the PSU – the side that faces inside your case. Again, this seems like a minor flaw due to the small amount of power it will put out, but if I was running my computer under load 24/7 as a, say, budget home server – I would get slightly uncomfortable about any possible hotspots.
Though not exactly a disadvantage; I’ve only had this for a couple of months, it may fail on me tomorrow as it is my first time using this specific line-up, so do take what I say with a grain of salt as your results may vary.
There isn’t much you can really say about a PSU, rather you have to rely on reviews, and this one gets pretty good reviews. It’s not a top-end PSU so you can’t expect the very best, but it is far better than your cheap PSU and it will perform better for longer. Don’t eve expect any PSU to last forever though because they just don’t.They may well keep providing power for years and years but most seem to develop irritating noises well before they actually fail. The more expensive they are generally the longer they last, but there is no real guarantee. I bought two CX’s and one started making strange noises within about four years. The other is still going strong. This one is to replace the one that’s gone all noisy. Not bad really
I had the previous model CX600 in a system I put together. It failed, and when I looked in to fixing it, I was shocked to find the system was over 6 years old! I found this newer model and decided to stick with “the devil I know”. It is working fine and my system is back up and running. The only problem I had was with the SATA power cables. The leads on these supplies are all pretty long, but the SATA power connectors on the new supply are upside down on the cables compared to the old one, and so I had to be slightly more creative in the way I ran the power to the 3 hard disks I have in this PC.
Not very powerful (obviously 450) It’s quiet enough, though audible enough it’s still not very loud, easy to install, very tidy & cable management was a breeze. It’s also a very small unit so if you do have a small case this is a good pick; in my relatively generously sized case it just made cable management even easier.
I’ve had it for a short while now and it runs very steadily, I play demanding enough games almost everyday and it’s a solid temperature. I would recommend it, I wouldn’t buy 450 again myself as when I do buy another it will be more powerful this was just to replace a 650 that died from a different manufacturer.
Have no problems with PSU, the only problem i have is the PC Case it went into.
If you buy either this PSU or any other make sure it fits in your case properly checking measurements prior to installing the PSU.
The PC Case I’m referring to is the Coolermaster N300 Case where if you use a small psu it will miss two of the supports it is supposed to rest on, also by doing so damages your psu, have informed company i bought case from, will also be informing Coolermaster.
Ppl just be careful when you choose a case and PSU don’t do what i did.
So far I have been very impressed with the Corsair CX450M. From the unboxing to the quietness, it provides you with a good package. This PSU doesn’t get louder than your case fans. I purchased the model with modular cables, as I wanted a clean setup for now, and I plan to upgrade more things later on. Installation was very simple, as you can just slide it in the PSU slot in my NZXT S340 case. Being a Semi-Modular power supply means aside from the two motherboard connectors 1x 24pin and 1x8pin, which at your convenience can be split in half if your motherboard only requires a 4 pin connector. All the other cables can be plugged in when you need them which makes installation and cable management really simple.
In The Box
As you tear open the Amazon box, inside you are greeted with a nice black and yellow accented box. Then the PSU is protected in some bubble wrap, along with all of the peripheral cables:
Main connector 24 pin ATX
1x 8pin cpu power connector (8pin/4pin) 1x PCI-express cables (8pin/6pin ) (I currently don’t own a graphics card)
6x Sata connectors
4x peripheral 4pin molex style connectors for drives/fans etc.
2x floppy connectors (I won’t be needing )
You also get an instruction manual, and some cable ties to deal with the behemoth of cables that you are now going to have to deal with.
Pros And Cons
Pros
Semi modular
The cables are black, so no ketchup and mustard cables to put up with
Remains relatively quiet
3 year guarantee
4/8 pin cables can be split
Cons
Quite pricey
Cannot fault anything else in this PSU
Final Verdict
Asides from the price tag, there is nothing that I could fault about this product. Corsair makes sure you are provided with a power supply that is quiet, efficient and one that will last you a good while. This PSU is semi-modular, so you can achieve a clean, well cable managed PC.
