2 out of 5 eggsLoud cooil whine

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: worked excellent for a few months

Cons: after a while I started noticing a loud buzzing coming from my case which turned out to be the PSU. It only happens under full load which points to poor craftsmanship. Hopefully I can RMA

Other Thoughts: none

5 out of 5 eggsSimple. Beautiful. Powerful.

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: This power supply is very sexy, if they can be classified that way. The packaging was elegant and very well thought out. The cables came neatly organized and nicely labeled on the box. It was such a simple install, I was wondering if I did something wrong. It is extremely powerful and quiet. I can't highly recommend this enough.

Cons: None so far. Becoming a Corsiar fan boy!

5 out of 5 eggs4 years+

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I bought this from newegg in April 2010. Currently powering SLI GTX680's, 2 HDD, and a full water cooling loop. I have had no issues with this PSU. It even comes with a nice, tough bag to store the extra modular cords.

Cons: after 4 years and over 6 builds with this unit, one or two of the PCI modular cables is showing exposed wire. This is because I have been bending the hell out of the cables at the base of the plugs for a cleaner look. This is easily repaired with electrical tape. More my bad than Corsair.

Other Thoughts: Still going strong after 4 years of almost daily use, lot's of OC'ing experimenting, fails, gaming, heat, power outages, removals/installs- you name it. Very solid.

5 out of 5 eggsgood psu

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I had a Gs 600 from corsair, that model is garbage, due to the noise when under load, sounded like ticking: however when I bought this psu there were no issues, modular.
easy to install easy cable management EASY

Cons: nothing

Other Thoughts: I will be SLI two gtx 660tis and this psu should be enough to handle it.

5 out of 5 eggsExcellent PSU

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: This power supply comes in a suede case. Need I say more?

This is a spectacular PSU - silent, with loads of horsepower to power pretty much anything you can throw at it.

I purchased this unit because of Corsair's high reputation in the PSU market (I previously purchased Antec units, but Corsair has been slowly winning me over). It's also a beefy 850w to power pretty much anything.

It's modular, with a very assortment of cables that come in their own high quality bag.

My biggest complaint was that it didn't fit very well in my Corsair 400r case - but this is the case, not the PSU, as I confirmed that this thing is standard and should fit just about anywhere. In case you wondering, it does fit in the 400r, it's just that one screw doesn''t line up properly - forcing you to use another hole to hold the PSU to the case by essentially creating a clamp around the case material. It's not a big deal, really.

Oh, and did I mention this thing comes with it's own suede pouch? Sexy.

Cons: Didn't align right with my Corsair 400r case - but I knew this was an issue from reviews ahead of time. It's not a huge ordeal to remedy the problem without making any changes to the case or PSU - you just need to use another screw hole.

5 out of 5 eggsNice PSU

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Voltage stable, runs two r9 290's with no issues. Packaging is nice, the modular cables are cool looking and well organized. Runs cool.

Cons: Not cheap, but it feels expensive, so that's comforting ;)

Other Thoughts: Given me no problems inside a pretty cramped case. Solid PSU.

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: *The power output is very reliable as it has been in service for well over a year. (hard years at that).
*very durable.

Cons: *None
Read other thoughts though....

Other Thoughts: Great overall Power supply. I was wondering whether to do a 4 or a 5 star only because i have NEVER seen the fan run on it. It could very well be burned up. However it does say that it is temperature controlled and my case does have a considerable amount of cooling. It is quite possible it has never needed to turn on.

None the less, it still continues to work for me(over a year so far) and that is all i care about.

1 out of 5 eggsChirping Problem x2

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: The power supply runs mostly quietly, see cons below for more detail. The power supply looks nice and the modular components make it easy to install.

Cons: I had to RMA the device once and I'm probably going to have to RMA it again. I got a replacement PSU because the first one was making occasional high pitched 'chirping' noises after a little over a week. This is a pretty high end power supply and I shouldn't have it crapping out after 1 week. (The wattage this thing supplies is well over my needs.)

I got a second PSU and lo and behold after about one week CHIRPING. This is unbelievable. Now I have to send this one in and wait for a new PSU to arrive from a more reliable company.

Will never be buying from Corsair again.

1 out of 5 eggsWhat a bust

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: none did not work

Cons: Did paper clip test and turns on for 2 seconds and then dies. Wanted to use it for bitcoin mining with my S3 bitmain device but this sucks. The paper clip should enable the 24 pin connector and turn on when loaded

Manufacturer Response:

Dear Customer,

We're sorry for the inconvenience caused by your PSU. For a replacement, please contact us directly at 888-222-4346 or submit a ticket at corsair.force.com and we will be happy to assist you.
