Conclusion
They say that some things get better with age, and in the case of Corsair's HX series at least I'm inclined to agree. The HX620W was a great PSU, the HX1000W even better. But when it come to designing and building the HX850W Corsair have realy pushed the boat out and delivered something that is truly special.Right from the word go the HX850w impresses. The packaging, the accessories, the immaculate powder coated finish. It all makes you feel like you've got a PSU that is just a little bit better than the rest. Then there's the flat 'ribbon cable' style modular cables. They may have made their first appearance quite some time ago, but they really do look the business inside a PC, and as you'd expect Corsair have provided enough cables to hook up everything from a triple-GPU gaming system to a storage junkies RAID array that would make even Google proud.
But the real star of the show is the performance. Never before on OC3D have I come across a PSU that can laugh in the face of our load testing equipment by deliverying rock solid voltages all the way up to its rated output along while also operating as cool as a cucumber and delivering insanely high levels of efficiency.
Even in the cross load tests that normally bring most PSU's to their knees, the HX850W continuted to operate as if nothing was happening. Furthermore, the recently introduced 'Max Load' test really showed just how powerful the HX850W is with the unit hitting 1084W before starting to show signs of strain.
To cut a long story short, the Corsair HX850W has raised the bar for what consumers should expect from a PSU. No longer do you have to choose between performance, efficiency, looks, price or silence. The HX850W has it all.
The Good
- Extremely high efficiency at around 90-93%.
- Runs so cool, it almost seems like it doesn't need a fan!
- Excellent voltage regulation on all rails, even in cross load situations.
- Ripple almost non-existant on +3.3v and +5v rails. Also very low on +12v rail.
- High quality internal components.
- Great modular connector system with plenty of sexy 'flat' style cables.
- Well packaged. Hardly any chance of damage during shipping.
- Delivers so much more than what it says on the box. 1084W to be precise!
The Mediocre
- Would quite like for hard-wired cables to use the same 'flat' style cables as the modular connectors.
The Bad
- Nothing at all
In recognition of the HX850W's outstanding performance Overclock3D is pleased to award the unit our highly coveted Best In Class Award in the PSU class of 850-1000W.

Few days ago purchase coolmaster 850 modular. i thought it will be quiet and many online test reviews say that, but the actual PSU make annoying noise like small transformer what make him louder then own cooler. can you,please, tell me is Corsair hx850w have any annoying cracking/bugnoise accept cooler. will you say it is really quite PSU.
Have to say that I have being using the HX850w for nearly two months now and I am kinda sorry that I bought it. It is much louder that my last psu ( tagen turbojet 900 ).Then all I could hear were the hard drives. Can get on your nerves after a while but I am stuck with it as I sold my tagen.

I find that really surprising. Are you sure your HX850w doesnt have a faulty fan? The Tagan Turbojets are named that way for a reason...they sound like an airplane taking off.
The tagen for me was very quite.You could just about hear it when it was working hard but it had no anoying 'whine'. My HX850 on the other hand has an soft but noticable 'whine' that gets on my nerves. It just has a different sound that I dont like. But thats me and others may have no problem with it.

No, not neccissarily.
I've heard some complaints about the noise of the two new HX-Series Units.
Maybe you had the version with a Yate Loon fan and he had one with Ong Hua fan.
My HX750 is lovely and quiet.. Only thing I can hear is my pump vibrating against the foam I have it on. Hmmm have to sort that out.
I bought the HX750 just over a week ago, have to agree very quiet, I much prefer the cable connectors on these PSU's too - 7 year warranty which Scan will cover for you which is excellent. :cool:My HX750 is lovely and quiet..

That's great! That's quite a very informative post. Thanks for your share.
I myself own a HX850W , runs cool and quiet - amazing PSU .
The best PSU ever made i think !!! If u have noises seems u can stop the fan and PSU dont overheat :) And also seems it can handle even more than 1084W if u do something with protections ;-) Really verry nice PSU !!! I have it a couple of monts and will buy it again :)
