Pros

Really good psu when on sale.
Cons
Better quality supplies around this price point. It's not modular. 4 pin connector was short for a mid tower case.
Summary
A good psu. I have not experienced any coil whine. Bought it half price during a sale. 4 pin connector was a bit too short for routing in a mid tower case. It's not modular, so I had extra wires in my case.

Pros

Good price.
Cons
Unreliable.
Summary
I used this PSU in my dads comp, and it died after a couple years, I was very surprised, corsair products are usually great.

Pros

looks very sleek with good cables
Cons
inherent problem with this model (buzzing noise)
Summary
Overall it's a good power supply but after a little research I found out that this model is very common to have a coil whine (which I have).

Pros

Cheap
Its Corsair
80 Plus certified
Cons
Non modular (tho its cheap, didn't expect it to be)
Summary
Bought this to replace a friends dying PSU. It has worked perfectly since day 1, and my friend is no longer having computer problems. Its also a Corsair so you know you are getting a quality item.

Pros

-Black, sleek.
-Large fan
-Not too loud
Cons
-Only 400w
Summary
I used this to replace my uncles 460w cooler master that failed. I am grateful that I could find something for 30$ that suited his needs. Its pretty good looking too, with a nice lower 120mm fan intake. I am a fan of the design. This is the perfect piece to add to any budget, non-gaming build.

Experience: 90 Days

Pros

+ Looks nice
Cons
- 4 out of 7 died within 1 week of installing.
- 1 killed an SSD
- I wanted to make this a 1-star review however they were in-store purchases.
Summary
I build & repair computers for a living. Never in my life have I seen such a terrible computer component. Out of an order of 7, 4 f these died with 1 week of installation, causing great headache to myself my clients and my staff. We have been using Corsair power supplies without issue for years, but this CMPSU-400CX model will definitely never be used again. Another 2 power supplies have not yet been used, so their fate I do not yet know.

DO NOT BUY!

Pros

Bought it on sale
Short length
Looks sharp in my black case
Cons
for a non modular, low wattage, high efficiency PSU...None
Summary
I put this in my WHS 2011 build. Since it doesn't need to power much and will be turned on 24/7 I insisted on getting a lower wattage PSU for efficiency. The cables are easily tucked away, fan is quiet, everything is black and looks good with my Lian li Q25B mITX case.

Experience: 2 Months

Pros

Good price
Good performance
Cons
None
Summary
I bought it for a friend 2 months ago for his new desktop. It works as expected and has a good price/performance, couldn't go wrong with Corsair if you're looking for a decent PSU.

Comment: Corsair CX400W is an excellent product for the regular user that is building a PC with just one video card.

Comment: There are power supplies such as the Corsair CX400W that didn't stick out too much during testing but still offer a very attractive price tag. If you do have only around $50 to spend on a power supply we suggest you have a closer look at the Corsair CX400W, or the OCZ ModXStream Pro with 400W if
