This review is from: Corsair CMPSU-450VX 450-Watt VX Series 80 Plus Certified Power Supply compatible with Core i7 and Core i5 (Personal Computers)

Finally, a power supply that exceeds my expectations. I've been trying to achieve quiet computing on the cheap for years, thinking that the latest and greatest "quiet" $40 power supply would sound less like a jet taking off. For this one, on the other hand, I actually had to get a flashlight to make sure the fan was moving!

The construction of this reeks of quality. Everything from the classy packaging, the helpful manual, and the nice mesh around the cables to keep them from getting hot and/or tangled. This comes with a 24-pin ATX power cable, which I hadn't encountered, but they designed it so that a little grunt work will remove the extra four pins. An adapter might have been a little more elegant, but that's being picky.

Very highly recommended - this is an excellent piece of gear!

Works like a charm, easy to install and features a powerful set of fans. This PSU is a dream come true for all people with a single GPU system; the 12v rail is plenty powerful for your graphics card (will run the recent 8800GT just fine!); the only downside is the lack of customizable / removable cables that the higher-voltage versions have, but due to the excellent cord wrap, they can be tucked away safely without getting in the way of any fans or vital system parts.

5.0 out of 5 stars Excellent - Just beware if you plan to put it in an older or small case..., March 29, 2010

Overall, I was very happy with this power supply. It appears of good quality for the money and the mesh wrap around the wires made it easy to organize them within the case. Corsair even included some tie wraps so you didn't have to go searching for a few if you like to keep your routing neat and tidy. The standard drive connectors were aplenty and fit more snugly than most.

Beyond all existing reviews I don't have too much more relevant to add other than a comment on the location of this power supply's fan, which is a large fan located on the top. While that is obvious from the photos, it is not obvious that there is no exhaust via a traditional rear fan or to any other side so your case will require an opening or have significant space above the power supply for it to vent properly.

Installing this into an older mid tower case where the power supply mounts against the top of the case meant that I was going to have to modify the case so that the fan exhausted properly. This was no problem for me as I'm adept with sheet metal fabrication and already own a 5" hole saw, but I realize that is not something most people have laying around the house. The top of my case also came off easily so I could make the modification off line without having to remove the case components or risk filling it with metal filings.

So in conclusion, if you plan to put this in a smaller or older case, it either would be wise to check your case to see what is above your power supply and be prepared to modify your case or chose another power supply that vents in a more traditional location.
