      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.

      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!

      A great budget PSU

      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.
