    Entry-level semi-modular PSU

    I build PCs as a hobby for use as HTPCs, gaming rigs, and most recently as crytocurrency mining rigs. This PSU was purchased for a mining rig. Corsair is a top quality brand, and their warranties are fantastic (I've personally had to RMA a PSU that failed after 1.5 years in an HTPC, and they replaced it with a more current PSU that had a higher max wattage and higher efficiency rating with minimal hassle). When running a $1000 rig 24/7 at 100% draw for the GPUs, you don't want to cheap-out on your power supplies (though I sort of did by going for Bronze rather than Silver or higher). Plus, modular PSUs just make cable management (even in open-air rigs) much easier. This PSU is semi-modular in that it has hard-wired connections for the mobo and cpu power, and modular connections for everything else. This is fine because with very few exceptions, you'll always be using the cpu/mobo connections in any PC setting. Only some of the cables are sleeved. The PCI-e, mobo, and CPU cables are sleeved, but the SATA and molex cables are not. While this isn't a deal-breaker, it is bit of a let-down because it affects the aesthetics in a traditional rig, and the way the non-sleeved cables are laid out (almost like old ribbon cables) they can be difficult to bend and manipulate. At $99 for a 750w semi-modular, 80 Plus Bronze PSU, this is the absolute upper end of what I'd be willing to pay (I had a gift card, so it was easier to justify, and it was available in-store when I needed it). It has worked without any issues providing power to 3x R9 270s, a 65w cpu w/ stock cooler, 4x 1gb sticks of DDR2 ram, and nothing else. I would not recommend running 3x GPUs of this PSU for a traditional PC with additional fans/peripherals unless you are using one of the newer Maxwell-chip cards. But again, I've had no hiccups with it so far, and I trust Corsair's warranty fulfillment unconditionally.

    I bought this power supply in the store and once I installed it, it would cause issues on boot up and under load since day one till it died and it was rated well above the required power for the custom pc I just built, and dealing with corsairs tech support for weeks and them saying I was wrong and doubting me when I said it was the power supply finally I bought a EVGA Supernova 650W it instantly fixed the problem pc ran so smooth no issues like before then I call corsair explain the new power supply fixed it they finally let me rma it but because I lost the receipt I can only rma it once for the 5 year warranty and I have to pay the shipping and after all hassle with there tech supports and the fact that product is extremely poor quality I don't even want to rma it anymore I just rather not deal with corsair in the future.

    Solid PSU - Always Use This Model

    I've been using this model from Corsair since before it was called the "CX750M'. I currently use one, and I will probably write another review for how the next one I buy works for my little brother when we get his when we upgrade his 8800 GTS to something a little stronger. This review, however, is for one I helped buy for a friend when he was doing a new build following an older build. He plans to upgrade his 750Ti to a GTX 1080 and change his AMD noname CPU (from when they just named them according to how they ran against Intel CPUs) to a top of the line i7. So far, it has run fine and has been a great upgrade from his HP prebuild 300W fire hazard. I recommend this PSU as a default choice for a one-card one-CPU build (if you are doing i-Series or one Xeon), and if you need something beefier, I always recommend staying with Corsair. In my build, I currently am running an EVGA SSC GTX 970 with an i5-4690K, and I have not had a problem yet. If I planned to overclock and up the power target beyond 100%, I think I would still be comfortable with this PSU. When I go forward with this build and future-proof it with a second SSC GTX 970, I think, if the wattage calculations still stay below 750 with a load, I would STILL trust this PSU.

    Great Power Supply

    Well this is my first PC upgrade I'm working on and I purchased a Galaxy - GeForce GTX 650 Ti Boost 2GB GDDR5 PCI Express 3.0 Graphics Card. It needed a new power supply and I wanted to get one that would be strong and last a while. A friend at Best Buy recommended going with the 750 and after reading the reviews I chose this power supply. I ordered it early on a Friday and received it Monday at the store. The reviews I read did not disappoint. This was my first time upgrading a power supply and it was really easy. I like how the cables are removable from the power supply and it keeps everything clutter free. I have a rather small computer and I still fit it in smoothly. I have an older motherboard and the 8-pin connector easily pulls apart to a 4-pin connecter to connect to my CPU. My computer is quieter than before even after installing a much better graphics card and PSU. The matte black finish easily scratched in my smaller computer shell and the sticker in the middle of the PSU is already coming off. I still give it all 5 stars!

    I'll start by saying I am a loyal Corsair customer and have been for over a decade. In four machines in my house there is not one that doesn't have at least one or two Corsair components. This is the second Corsair PSU I've purchased after a 650HX, and I'm happy with what I received. To keep costs down, this PSU doesn't come with the nice cloth bag to hold your extra cables, and the cable wiring itself is a little thicker/stiffer than my HS, but for 100W more power at $100 less cost, I can handle non-PSU related cost cutting. This PSU went into an older Core2Quad gaming machine which will see about $350-400W pulled peak, and so far I've not heard the fan kick on at all over the case fans. Voltages have remained steady and are just above their rated amounts (which is what you want). Without having it for years it's hard to say it's perfect, but if my track record with previous Corsair equipment is anything to go by, it will far outlast any of my expectations.

    The modular nature of this power supply helped keep the internal clutter of my old PC build to a minimum. It packed right in, was quiet, and does the job just fine. I know it's a power supply, so it's not exciting, but it did help me keep my old machine running while I wait for new updated processors from Intel for my next build. I replaced an almost 5 year old Corsair power supply that was a workhorse on my 3d rendering machine. I put the old one through its paces and thought I'd stick with corsair for the next one. 2 local BB employees actually built their own computers and were able to answer a lot more questions than I would expect about power draw, video cards, and cabling inside a home built desktop. I couldn't be happier with this purchase. Why wait for 2 day shipping from a big online retailer when I can just go to my local Best Buy store and fix my computer in 20 minutes that same evening?

    Upgrader

    Bought this for an upgrade to a DELL 8500 i7 Mid Tower. Upgraded the GPU to a EVGA GEFORCE GTX 770. The card needed one 6 and one 8 pin power connector that the original power supply did not have. Upgrading the PSU was simple, just follow the cables from the PSU to the motherboard, fans, and drives, disconnect the old power cables one by one, matching and plugging in the new cables as the old ones are removed, and remove the old power supply, removing the retaining screws and bending the retaining clips back on the chassis to release the power supply. Find the new required cable for the GPU, and install all the new cables on the new PSU. Fit the new PSU into the case (needed to bend the chassis retaining clips out of the way, as the new PSU is larger). The new GPU runs cooler and quieter than the original.

    I upgraded to this power supply after a name brand 600w power supply from Best Buy died on me after 3 months. Not running anything crazy- an amd 8 core, and one graphics card. This is my first fully modular power supply, so I appreciated being able to remove unused cords from my case. I am most impressed with the noise, or should I say, lack of noise, this power supply puts out. It runs very smooth and quiet and I haven't had any issues with it so far. I'm happy with the wattage in case I want to upgrade to two graphics cards in the future. I had a smooth time with in store best buy staff when swapping my in warranty 600w for this one, and I just needed to show my best buy rewards history (since I made the mistake of tossing the receipt). Warranty is 3 years, which seems fair enough considering how often I build a new computer. Highly recommend this baby.

    Horrible product and horrible Best Buy service

    Chip

    I have bought two of these things so far. The first one lasted 3 months before i smelled a faint burning electrical smell. that same day it completely shut off. Replaced it with another one, thinking i got a bad one, and the second power unit did the same thing after only a month. Replaced them both with the original 650W PC power unit, which is cranking away just fine. No reason why my computer would be too strong for a 750W and okay with a 650W. Opened my big mouth when i tried to take the second one back, and Best Buy refused to take it and told me to go through the manufacturer. Yeah, because that always works out great. Corsair makes good memory chips, but stay away from their PC power supplies. It will be a long time until i shop at Best Buy again.

    Easy to install. It's heavy telling you that's its quality. The only thing during the installation I did not like. Was the fact that they tell you it has 8 SATA CONNECTORS, there are 2 strings of 4 so you have to plan you cable management. I have put this thing under a good load and its holding up. It's not getting hot. I can't say much about the fan because I have so many on my tower to hear it. System setup AMD FX 8320 Asus m5a99fx pro R 2.0 10gb DDR3 1600 Nvidia gtx550 ti (175watt) Corsair h80i water cooler 2 DVD rw 6 fans And 6 UBS devices drawing power from the power supply So I still have room to expand if I need to.

    Clean install, reserving judgment on longevity

    I had to buy this unit on the fly because my other Corsair power supply failed at random after nine months. This was the best option available in store at my local Best Buy. Luckily it was on sale for the Amazon price (Best Buy is usually overpriced on components). Unlike the CX600 I had before, this unit is truly modular: only the motherboard and CPU power cables are permanently attached. This made for a much cleaner installation than the CX600. So far my system is humming along just fine while I wait for my replacement from Corsair, which will probably end up being used for another build down the road. I'm giving the product four stars for working out of the box, but from now on I'll reserve my fifth star for products that have help up for more than a year without incident.

    Faulty product

    Not too sure if I have the worst luck on earth or if it is the company who is making this power supply but I purchased one that had happened to be faulty (it would overheat). I contacted the manufacturer for a replacement and received one with no problem. After installing the replacement, it overheated again and the fan did not kick in at the time of heating. So, I decided to purchase a new power supply manufactured by a different company and have yet to have problems with the new one I purchased. Based on the other reviews, it seems as if I the most unfortunate man in the world. So, based on my experiences with the quality of the product and the services of the manufacturer, I cannot recommend this product.

    Replaced a Corsair 620HX one of the first semi/modular psu's. { I could go and get this and replace same day, when I bought mine .. they did not have 3 different versions - lines } After purchase and it not lasting 2 weeks. I did a little research and found that this series of the new Corsair line did not have a very good track record. I was pleased when it went, it did not take anything else with it. I did replace it with a AX series of the Corsair line and it has performed as well as the original so far. If you are replacing a OEM psu of the same wattage or less, you are probably going to be ok. If you are a builder / custom builder ... then look at one of the better lines from this supplier.

    I bought this for the new build, works great and being that it is modular the cable management is cleaner. I do have 1 thing to comment on, not an issue as I gave this PS a 5 star rating. With my build/case setup, I added 4 additional case fans for intake. Being that these were added to the already 3 case fans, there were no remaining 3 pin case fan slots on the motherboard. This power supply does come with peripheral cables that end in a female molex, but it is up to you to purchase the cable that can hook these up to the remaining 3 pin fan power cables. Again, not a huge issue, just make sure you do your research on ALL of your cables before you say to yourself, "I'm all done gathering the parts, now time for the build." Again, great PS definitely a go to brand.

    Well, Pinky, it crashed faster than one of Brain's plots to take over the world. If Uwe Boll made power supplies, instead of atrocious movie adaptations of games, this is what he would have created. It's like the E.T. Extra Terrestrial of power supplies, it should be buried in the New Mexico desert. 15 minutes after boot up, the PC shut down. Took it to a repair shop, and they said the power supply was bad. Cost me $30 extra for the diagnostic, and I was without my computer because of it.

    I like the semi-modular style of this PSU for cable management. It seemed to be a good unit until 10 days after installing it and my new EVGA GTX 1070 SC. Whenever the graphics card was under load it would produce a lot of coil whine from the PSU. At first I thought it was my graphics card, but was able to isolate it to the PSU. Some people might be able to live with that coil whine, but it was too loud for me... I have now installed an EVGA 650 GQ and am very happy with it, not to mention it's about the same price for slightly less power but much better components. Just get the better PSU, it's worth it!

    Had PC issues where my 5v was showing red, it would cause my computer to restart, crash and sometimes just not power on. Two PC places did a free diagnostic and couldn't find out the problem. The first one suggested getting a new PC. The second place couldn't find anything wrong and just suggested upgrades. Having had to replace a PSU before and having had similar pc problems before I decided to replace the PSU to see if that would fix my issue and if it didn't I knew I could return the product since it would be known to work within the first few days. It was easy to install and I enjoy that I as able to save space due unused cords not needing to be attached.

    Since I had to replace my desktops PSU several years ago I was sure I needed to do it again when I heard my other desktop fans on "high" all the time. This unit just slipped right into the case and was easily attached to the motherboard, drives and graphics card. Its somewhat modular but I wound up using most of the cables due to my setup - BUT its still a nice option to have to not have a lot of unused cable cluttering up your machine. Has a 3 year warranty which I found acceptable for its "bronze" rating and price point. A nice unit all in all and its nice to have my quiet desktop back.

    My power supply failed so I needed one during my warranty RMA for a replacement. It was a few pounds lighter than my power supply, at the same wattage. Not sure if it is using cheaper components. It will get the job done, nothing special other than the modular cables, but that is becoming the norm. No louder than my previous power supply. Final note the CX series Power Supplies are the lowest line of power supplies @ 750 watts. I paid $79.99, really this should be priced around $59.99 as it is a bottom line power supply from Corsair. I would only use this for single graphics card set ups (No SLI, or Crossfire). And no Over Clocking. Just a basic PSU here.
