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.

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
