From the Manufacturer

HX1050 hero

Quiet operation at low loads, modular cabling and 80 PLUS Gold efficiency makes HX Series PSUs a great choice for high-performance PCs.


Overview

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.

Features

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
  • The ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature
Superior components for better performance
  • Active Power Factor Correction (PFC) with PF value of 0.99
  • Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components
  • Engineered to meet maximum power output at a server-grade 50°C temperature rating
  • High-quality capacitors provide uncompromised performance and reliability

You can hear the chirping noise at ~3 seconds in and again at ~27 seconds in my video. The sound is very noticeable even when sitting at my desk, but I filmed right at my computer so you can see the fan. The sound seems to occur when the fan is changing speeds and is definitely worse (ie occurs more consistently) when my room is at certain ambient temperatures. Seems to happen less when it's colder.

My system is dead silent besides the PSU and it's driving me crazy. This is my RMA replacement unit so whatever is causing this is not yet fixed in production. Avoid this PSU like the plague and spend your money on something else. This is not a cheap PSU which just adds to the disappointment.

***UPDATE 1/25/2013***
Corsair will be replacing my unit with an HX750. Support says that this unit does not have the same issue as the HX650.

I'm going to read between the lines a bit based on how quick tech support was to suggest swapping to a HX750, but it sounds like there are known issues with the HX650. Crossing my fingers that the HX750 does not have the same issue, but I am pretty optimistic as amazon reviews for the HX750 do not note this issue.

I actually purchased this power supply unit before reading any of the reviews, it was dumb on my part. But it's not a bad power supply, it does exactly what it says it does. From my understand the chirping sound is coming from the gold coiling within the power supply unit. It doesn't make the sound when I'm gaming or when the computer is under heavy load, so it doesn't bother me too much since that's mainly what my computer is under anyways. It's a great unit, however it's not fully modular as stated, it's actual semi-modular, but quite frankly if you aren't an enthusiast, you aren't going to know the difference. I bought this unit for a good price so I'm not complaining.

/Edit 1/3/2013

After about a week after I bought it, it stopped powering my graphics card, the chirping sound also progressively became much louder.

Ok let me start saying that power supply performance is some how as advertised. I got first one and right after I installed it, power supply start making chicken type noises. Every time fan turn it self on to cool down the power supply and then start slowing down, the fan start getting out of balance and start the noise. That would happen every time temp. would go up to 80F in the room and start driving me CRAZY!!!
I called Corsair, they told me that they AWARE of this problem, created RMA, charge my credit card for new one (I could not send the one I had until I get new one and I could not wait for the replacement a week, so in order for them to send me new replacement they put hold on my credit card, witch was promptly returned the moment UPS conformed delivery of faulty power Suplay back to Corsair), and send me UPS tracking number for the replacement.
Perfect right? WRONG! This is where everything takes a turn to problems. First when I receive the replacement it was a wrong model, let say not the one I had Gold but older model $40 cheeper. First I called and ask what is the deference between the one I have Gold and the one they sent me, (of corse I had not told them that they send me wrong replacement, just to see if maybe replacement is better then Gold, this is how I founded out that the one they sent me is old model). The deference between this two was, Gold had better performance and it's better in power consumption. After quick conversation I had been told by Corsair costumer service that Gold is better and Gold is better buy. I hang up with this guy and called them again, this time with bitch attitude. Corsair understood my problem and overnight me another one of power supply. This time the right one, I promptly replace servers power supply with new one and power it on.

The same issues as everyone else. Loud twittering/chirping sounds when using demanding applications. With me it happened within half an hour of gaming, or 3d modelling. Sometimes within minutes. Partly my fault as I didn't read the reviews, I just went on Corsair's brand name, the wattage and the 7 year warranty.

The replacement unit had the same problem only worse. Apart from the twittering sounds under load, when idling the fan made an audible whirring noise above my 3 case fans. It would start up for about 10 seconds every minute or so. I requested Corsair for the older model and they luckily had that in stock and sent it. The bronze (older) model is working fine.

I don't know why Corsair is still selling this. They should just recall this entire line. Just buy the older bronze edition and you'll be fine.

I am very dissapointed in this power supply I have been a longtime fan of corsair power supplies as they used to be bullet proof and provided very clean power I own a few of the previous generation Corsair HX650's and they have been nothing less than stellar when I heard that corsair rebooted the HX series into a Gold rated power supply I was realy excited and passed one of my older bronze edition HX650's to my brother and bought the new Gold edition HX650 for myself.

Upon opening the package of the new Gold edition hx650 I was immediatly dissapointed to find out that for some reason Corsair only has 2 pcie cables/connections so if your GPU requires both cables you can only run one card with this supply....the old bronze edition had 4 so you could run dual card setups.

My next problem with this power supply is noise when the fan increases and decreases speed the power supply makes an annoying chirping noise which get's louder the longer you use the power supply I returned the first to the store I bought it from and the new one had the same issue....went to the corsair power supply support forum and upon noticing many others having the same problem I then filled out an RMA and was assured I'd get a supply from a good batch after waisting time and money the new RMA supply had the same issue!.

I dug into this a little deeper and found out corsair does not build it's power supplies they swap out between 3-4 different companies to build them for them with seasonic being there top producer which coincidently seasonic made the older Bronze edition HX650 and the even older HX620 which both of those were just awesome they were quiet and way underrated powerwise (ran two gtx 580's with one) but this new gold edition is just garbage...
