Summary: The Corsair HX850 Gold is just one in a long line of 850W products we have seen from
. Indeed, currently,
Corsair has 4 different 850W products
. Among these current offerings we have seen all of these and so far all have been good products. However, this product, like the
, is a refresh and the track record for refreshes outperforming Corsair’s initial offerings solidly has not been great so far.
Summary: Corsair, a brand we have come to trust when powering our enthusiast desktop PC systems, brings to us an 850 watt power supply unit that touts quiet operation, a modular configuration, and "gold" rated power efficiency. How does the new Corsair HX850 fit into Corsair's current power supply lineup?
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.
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.
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.
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.
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
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.

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.
