Still running strong after 2 years

Pros: - Bought this back in March of 2016 and has been running perfectly ever since.
- Fully modular (cable management is awesome!)
- All the power connectors you will ever need.

Cons: None

Overall Review: Full recommend this for single GPU systems. You might run into power issues with dual GPU setups because it's 850W

Great

Pros: modular, quiet, lots of cable options, functions.

Cons: 8pin cpu cable is short depending on how its routed with a bottom mounted cpu. The premium cables might be longer?

Cosair Power Suppies Have High Failure Rate

Pros: + Nice power modular supply with good cables.
+ Very quiet.
+ No history of failing and damaging the PC.

Cons: - High failure rate.
- Usually good, but sometimes very bad customer support.

Overall Review: Of the five Corsair supplies I bought in the past several years, four of them failed within 2 years. This latest one failed after two months of light use. It's been two weeks trying to get Corsair to complete my RMA. I'm buying EVGA from now on.

Great Product

Pros: Has the connections needed. Has the connectors needed. Let's face it. Most people needing a 750 or larger PSU are planning to have 2 Video Cards. This has the space to plug in the necessary PCI cables.

Cons: The cables. They think they are giving you something cool by supplying braided cables. Beware. These things are a pain to work with. They are too thick to deal with and hide. I felt like I would never get the back cover on my case. The funny thing is they sell the typical "flat" cable on their site. 4 eggs because of the cables.

DOA

Pros: Fully modular and looks nice. Not too big and fits nice and snug in my case.

Cons: Dead on arrival. Will try and return it for hopefully a working one.

UPDATE 12/28/17: Bumping it down to one egg for two reasons; It was returned to me worryingly quickly right after Christmas. I opened it up and it was the same exact unit. I figured they must have done something to it. I hooked it up and pressed the switch and... still dead. Except now it makes an odd clicking sound which I didn't hear before. I just want to return it now and get my money back, which leads us to my second reason I'm bumping it down. For whatever reason I'm not getting the shipping label sent to my e-mail. I click "CREATE SHIPPING LABEL" multiple times and I get nothing in my e-mail. I realize that this is probably not Corsair's fault, but it frustrates me enough to take it out on them a-la my review.
