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!
Thing never even flinches. Best power supply I've ever had. First time I've ever bought a Corsair. I'd always bought the cheaper priced but higher watt psu's and until recently I never realized I was wasting my money then I read on a forum that even buying a lower watt Corsair or even a couple of the other better brand names your getting better more consistent power throughput then you are with the cheaper ones and it's much safer on your computer cause they are made from better quality material so they won't burnout and fry any of your other computer computer components along with it. I'm sure there are others that could explain better then I can but now that I kind of understand it I'm glad I bought this Corsair psu. It's working great. Usually by now with the cheaper ones I would have had to replace it by now. Also with the cheaper ones by now I would have had hissing coming from them. So far so good.
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.
Install was very easy, remove 4 screws on existing power supply and remove from PC case, unplug existing connectors. Slide in new power supply, attach with 4 screws previously removed and make connections to your motherboard, drives and video card (as necessary). This has 8 pin connector for motherboard (12V), but is split into 2 4 pin connectors - so if you, like me, have a 4 pin motherboard just plug in one connector and let the other hang loose.
Based on it's size this should fit any case that has standard power supply. The supply is extremely quiet. It's so quiet that I the only noise I hear now is the fan on my video card.
With 2 CD/DVD drives, 2 hard drives and video area, the 450 has plenty of connections, almost twice as many as I need today! Any unused connector just tie up and tuck neatly inside your PC case. Just need to note that this has only one PCI-E connector, so if you have more than one video card you'll need to get a special connector. I'd suggest if you do have dual video cards you invest in the 750W version of this supply, it has 3 PCI-E connectors. If you, like me, have no need for dual video cards this is more than ample to power your rig.
