Corsair HX850W (850w) ATX PSU

25 June 2009
  • 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.
  • Pros: 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 s...
  • Cons: 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.

Corsair HX850 Gold

31 July 2012
  • Excerpt: Three years ago, give or take a month, Corsair came in here with a new power supply based on a new platform, called it the HX850, and walked away with their first ever perfect score for performance. Today, they've come to me with the replacement for that unit in the newly redesigned HX850. This time, bearing 80 Plus Gold certification. Let's see if they've been able to keep that stellar performance the HX850 was known for.

Corsair HX850 Gold Power Supply Review

Hardware Secrets
30 July 2012
  • Summary: The new Corsair HX850 Gold performed slightly better on our tests than . Efficiency was higher at full load (at other loads it remained about the same), but the biggest advantage of the new version is that we didn’t see the high noise level on the +5VSB output that we saw with the original HX850. While noise levels with the original HX850 were very low, with the new HX850 Gold they were even lower.

Corsair HX850 PSU

18 September 2009
  • Conclusion: When you are in the market for a new PSU, one brand should always be the first on your list, Corsair. Corsair makes some of the best PSU’s, and have always combined shear power with great efficiency. With 850 watts, you can be sure that you will have enough power for future expansions, and will easily be able to run all but the most power demanding computers. This includes a huge RAID system, or a dual graphics set up, besides maybe a quad SLI system.

Hardware Canucks
5 August 2009
  • Conclusion: Considering just a few short years ago Corsair was a newcomer to the power supply market, it is truly amazing to see how far they have come. When you look on any forum across this great expanse we call the internet, you will see their units being recommended again and again. This trend led to several retailers admitted to us that Corsair’s power supplies routinely outsell their closest competition by a factor of three to one.

Corsair HX850 850W

22 June 2009
  • Excerpt: It seems an eternity since the last time Corsair released a modular power supply in their high performance HX line of units, and there has been a good deal of speculation around the net on when Corsair was going to finally release something in the 750W-850W range to better compete with the likes of the Seasonic M12D and Antec Signature units at that level. Well, the waiting is over because Corsair is releasing two new units at 750W and 850W to fill the void.

Corsair HX850W Power Supply Review

Hardware Secrets
19 June 2009
  • Summary: Corsair HX850W is an impressive power supply, being to this date the power supply with the highest efficiency that we’ve ever tested, beating and . The reason why these three models achieved 90% efficiency lies on the chosen design. Instead of having separated rectifiers for each output, these three power supplies produce mainly only one output: +12 V. From this +12 V output two smaller power supplies produce the +5 V and +3.3 V outputs.

Corsair HX850 power supply put to the test: how good is it?

12 June 2009
  • Conclusion: The Corsair HX850 is a modular power supply that currently etails for around £135, and the pricing is reasonably competitive with other big-name PSUs that also ship with modular connectors, aimed at the enthusiast space. Packaging and build quality are both excellent, thanks to good presentation and a range of connector-runs which should suit most folk. More good is to be found with the warranty on the HX850, now extended to seven years instead of five.
