1 out of 5 eggsFrustrated and mad.

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: Easy to install and I liked the connections being separate. It makes it easy to use only what you need.

Cons: Worked for a little while and then I began having trouble booting the computer. When it did boot, it would shut off and then on.Soon the computer would not boot at all. After wasting two weeks trouble shooting the computer motherboard, ram and CPU , I find out it was the PSU. i tried another PSU and it worked.

Other Thoughts: I still like the Corsair line of products. I would buy their products again if needed. I should have read the reviews before hand.

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: Quality and price if you get it on sale. Looks great, nice paint, wiring, boxing, fast shipping with NE, quiet, cool just s great PSU

Cons: It's big, was not able to place the lower fan. No other cons

Other Thoughts: The HX series is a great option for serous PC builders. You really cant go wrong. Corsair also has a great RMA program and does not require a receipt

5 out of 5 eggsHard core

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: Very hard core PSU. I built a I7 system with is going strong thanks to the PSU. I like the fact it comes with a lot of cables for all your needs. I like how quite it is. I never hear it running. Ever. I love the fact the fan is not always on and the fact the fan can change speeds depending on what kind of load is being pulled. I would recommend this to anyone with a high end system.

Cons: None

1 out of 5 eggsFailed - Disappointed

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: For more than 3 years it provided clean power. Purchased because of the great reviews.

Cons: Just up and died. Owned it for a little more than three years. I plan on submitting a warranty claim since one of the reasons I purchased it was the 7 year limited warranty. I will update this review if Corsair honors the warranty. In the mean time I had to purchase another, non-Corsair, PSU. Disappointed.

Other Thoughts: I have other Corsair PSUs. And never had an issue with them until the HX850.

Manufacturer Response:

5 out of 5 eggsGood

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: After spending way too much time researching, I settled on this PS to be able to power my dual GPU set up. To be honest, I've yet to run the dual GPU yet, so 850 may be a bit on the low end, but with one 3GB 2000 cuda core GPU, no problems. Fit nicely into the Corsair Obsidian 550 case. I like that its set up to pull air from the outside via the bottom of the case and through the back for the exhaust. This way no PSU hot air goes into the case nor does it pull air from the fresh air inside the case. Big plus IMO and the main reason I settled on this PSU.

Cons: None Really. Wasn't cheap, but as this is a part that can literally ruin your computer if it craps out, I wasn't willing to take the chance.

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

Manufacturer Response:

Dear customer,

We're sorry that you're hearing buzzing noises coming from the PSU. Please submit a ticket at corsair.force.com or give us a call at 888-222-4346 and we'll be more than happy to replace the unit for you.

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!
