From the Manufacturer
Quiet operation at low loads, modular cabling and 80 PLUS Gold efficiency makes HX Series PSUs a great choice for high-performance PCs.
Quiet operation at low loads
Basic PC power supplies have fans that spin whenever your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web. HX Series power supplies are smarter than that: they generate less heat, so they require less cooling, and the thermally controlled fan only spins when it’s needed.
Slay the cable kraken
The modular cable set allows you to use only the cables you need for your particular set of components. There’s no more unwieldy mythical tentacled monstrosity of unused cables to clutter up the inside of your case.
High efficiency, low heat
Efficiency is the measurement of how well a power supply converts the AC power from your outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.
HX Series PSUs are among the most efficient on the market. They help keep your PC cool and quiet, and your power bill down.
Reliable and efficient operation
- A dedicated single +12V rail offers simple configuration and maximum compatibility with the latest graphics cards and other components
- 80 PLUS Gold certification, delivering up to 90% energy efficiency under real-world load conditions

I forgot to mention that the 4 screws that comes with this unit does not fit my case because my case is surprisingly thick but the screws are short so I couldn't mount it in. The screws that was from the original 550W PSU for some reason did not fit well with this unit so I couldn't use those either. Good thing I had 4 screws long enough that fits perfectly with this unit that I found in my garage so make sure your case is not too thick otherwise you will have to buy 4 screws that will be able to fit with this unit.
I can tell this particular PSU was manufactured by Seasonic as its almost identical to the Seasonic 650 gold PSU I have in my AMD system, which is normally a great thing meaning fantastic quality, voltage regulation, noise control and many other benefits. Both are very good power supplies overall, this Corsair one simply offered a few more watts and better warranty over the Seasonic one. I've seen firsthand the incredible difference a quality PSU can make in any build and how many blue screens random lockups and other issues it can save you from. As such ever since my first build I've made certain to research and find some of the best PSU's on the market for my builds as my very first one is still running to this day 7 years later.
The biggest gripe I have about both PSU's though and particularly the Corsair version, was the cheap flat ribbon style cables it came with for connections to the motherboard, and drives which I am not at all happy with. They (unlike the PSU itself) felt thin, cheap and too ridged to allow for sufficient flexibility to reach and wrap around tight confined spaces as those you'd obviously encounter in a case. I felt that competing companies offered superior cables with full ribbon sleeves and color coatings and appeared much thicker than these ones I received. Overall I felt this seriously detracted away from the total quality feel of the PSU.
To be fair though this and the size issue have been my only major gripes with this PSU. Otherwise I've found it to be of excellent quality and have had zero problems with either one for several months of ownership and intensive use. I don't think you can go wrong with either one especially when you find them for under $100 like I did.
Update Feb 2017
Happy to report this PSU is still going strong after these years and powering my rig. I've gone through 3 graphics cards in that time with varying demands on the PSU this latest one being the most aggressive (R9 380) and so far the PSU has had no issues with any of them. One of these times when I'm really feeling it and need to I'll upgrade to dual graphics cards.
