Introduction & Specs
A little over a month ago Corsair announced two new PSU's to join their extremely popular HX line-up. The HX750 and HX850 are two models designed to bridge the rather large gap between the original HX620W unit released in 2006 and the HX1000W released almost two years later. As anyone who's looked into purchasing a PSU recently will tell you, both of these PSU's are widely regarded as being the best in their class, with Corsair not only using only the best factories to build the units, but also specifying upgraded components and various other modifications to improve their performance. In fact, in the case of the HX1000W, Corsair not only picked one of the best OEM's in the industry (Channel Well Technology), but also conservatively labelled the units 1200w output as 1000w just to ensure flawless results.So today we've been given the pleasure of being one of the first sites in the UK to check out the HX850W. Once again both the HX750W and HX850W models are built by CWT, but in a recent conversation with Corsair they confirmed to us that these units are no 'off the shelf' models. They are instead a completely custom design and specification, built after several months of co-operation between Corsair and CWT. However, before I get ahead of myself and start blurting out all of the juicy details let's check out the specs listed on Corsair's website:
- Guaranteed to sustain its full rated wattage at an ambient temperature of 50°C

(Queue Slobber)....Yes, if the specs are anything to go by then the HX850W is certainly going to shape up to be one drool-worthy unit. We have 105c solid state caps, a single +12v rail rated at 70 amps and up to 90% efficiency. Basically everything neccesary to certify the HX850W as PSU porn. Additionally, while I was bashing away at this page Corsair also received word that the HX850W had met 80PLUS Gold Certification. Stellar stuff.
However, I'm not going to let these mere words seduce me. After all the proof of a PSU is in the testing. So let's move swiftly on to the next page for a closer look.

Any info on this. would be interesting to hear as i need to upgrade my screaming PSU.
To be honest I'd totally forgot. I'll try and remember to dig the case out of the garage tonight and give it a whirl.
"Both the Corsair HX620W and HX1000W PSU's were massive hits among enthusiasts, but how does the recently released HX850W perform? Today we find out."
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.
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..

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 :)
