Reviews around price (4.53 of 5)

  • Efficient, cheap price, durable, and gets the job done well
  • Despite having bought this at an unfavorable price, the CX600 has proved to be dependable and good quality
  • All the power I need and could possibly need in the foreseeable future at a great price
  • Plus Bronze Power Supply delivers great power and performance at a reasonable price range.

Reviews around quality (4.50 of 5)

  • Corsair sources have largely defect known as Coil Whine (an annoying noise produced by the poor quality of its components).2
  • I replaced mine with an EVGA G2 750w, because not only was my cx750m noisy and low quality, it also had horrible efficiency
  • Very good quality unit with very tight voltage regulation
  • The build quality of this PS is decent but not as good as other ones in this price range
  • My power supply started smelling as if some electronic was burning after about a year

Reviews around product (4.21 of 5)

  • I was very nervous buying this product as I had never attempted to install a PSU before
  • This is an excellent product that was very easy to set up.
  • So I do not recommend this product because of my experience
  • It was a good fit and works great so far, good product.
  • the power supply works fine, but for the things I do (which I would imagine most people who would buy this would buy it for, that being gaming) it just is a bad product

Reviews around system (4.18 of 5)

  • Power supplies are an often overlooked system component as when they work well, you never notice them
  • It's the thing that can cause your system to be unreliable, and you never want to question if it's working right.
  • get a model which shuts the fan off when not under load if you want a truly quiet system.
  • I wanted a powerful, but quiet system that would overclock well with 24/7 stability.
  • and I have several internal and external Hard Drives including a 2T external hard drive and this Corsair Rmi Series ,RM750i power supply takes good care of it all with out any issues so if you need a powerful Power Supply then this could be what your looking for

Reviews around psu (3.88 of 5)

  • It was never an extremely quiet PSU, and so upgrading to the RM750i was great
  • PSU should be like this now, small works nicely and very quiet
  • Everything works, and the PSU is completely silent most of the time
  • great set of modular cables for any setup and a good solid dependable psu all around
  • The computer is NOT a gaming PC (it's a photo editing rig), so the PSU wasn't stressed.

Reviews around cable (3.25 of 5)

  • Worked great after installation, the modular cables make cable management very easy
  • Worked great after installation, the modular cables make cable management very easy
  • the cables are so stiff and difficult to get into place!!
  • The only issue I have is that the cables are a bit stiff, so it's hard to organize them properly
  • It was just as hard getting the other end of the cables to plug into the PSU itself (which is why I blame the cable)

Reviews around fan (3.24 of 5)

  • My only slight disappointment is that the fan is louder than my previous power supply
  • The fan in this power supply changes speed according to heat, so it is very quiet
  • Very quiet fan, comes with all the cables you could need

Reviews around 12v rail (2.37 of 5)

  • My power supply started smelling as if some electronic was burning after about a year
  • Unfortunately, the product does not look as good as in the pictures (only leaving this because the flat cables it is shown with were one of my primary reasons of buying)
  • I actually prefer this over braided designs as it is much faster to reach a nice looking result - less need to tie things down
  • Basically in "Single" position, the full output of the PSU 12V rail is available to any and all connectors.
  • Everything works as it should, I find it very useful to be able to measure the consumption of the PC in real time, efficiency, each voltage and its temperature

Reviews around plastic (2.29 of 5)

  • Unfortunately, the product does not look as good as in the pictures (only leaving this because the flat cables it is shown with were one of my primary reasons of buying)
  • The plastic makes the cables fairly stiff to bend easily (as many power supplies already do) and is difficult to really get a 'flat' wire setup when moving around a case
  • It is packaged in a very premium manner, including a felt drawstring bag for the main powersupply, plus a re-usable plastic fold-over bag for the modular cables
  • They are made of stiff black plastic, and some are ribbon shaped, which is a bit harder to work with and looks less tidy (circular cables can be tied easily in a tube shape, but the ribbon ones are flat and wide)
  • Everything works as it should, I find it very useful to be able to measure the consumption of the PC in real time, efficiency, each voltage and its temperature

Reviews around sound (1.69 of 5)

  • When I start playing games on my computer it starts making an annoying sound
  • , I can still here the annoying sound coming from the power supply
  • Although, with the size of the power supply, I doubt you won't have other components that will have more than enough fan noise so that you will never know how good the low sound is of the Corsair
  • I realize that sounded like a add and this sounds like a fake review for this product with those first two sentences
  • Initially made a very loud chittering sound at first and began the RMA process

Reviews around burn smell (1.41 of 5)

  • worked great for about 6 months and then it started producing a burning smell that filled the whole room.
  • and now I am getting a "burning" smell from this power unit
  • We do use the TX750M for the systems we build at my work, which stay on near 24/7, and those don't fail all that
  • 6 months later, on April 25th, I started smelling an electrical burning smell from inside my computer, and shut it down promptly
  • Was pretty good and quiet, but after only a little over a year of use it suddenly decided to get really loud and emit some kind of burning smell

Reviews around drive (1.27 of 5)

  • Suspecting there may be something wrong with the new drive, I pulled a known-good drive from a decommissioned system and connected only the mobo leads and the drive to the PSU
  • required power-supply capacity (watts) will depend on the CPU, video card(s), storage drives (hard drives or solid state drives), and disk drives (blu ray or DVD) that you are using
  • I was able to connect only one of my hard drives because the SATA cable is not
  • As soon as I turned it on it sounded like a REALLY BAD hard drive going out
  • I bought the HX1000i when it first came out, and it ran in my main system for a while, but I moved it to my server as I gained more drives in the server and more power efficient components in my main system.
