5 of 5 Great PS!! Sunday, March 09, 2008
A Customer from CDA, Idaho  

I am very happy with this purchase. It was so easy to install and the modular cables got rid of the tangled mess. Runs nice and quiet and gives ample power to my new geforce 8800GT.

5 of 5 Quiet bliss Tuesday, February 26, 2008
Jim from Glenmont, NY  
This PSU was highly rated at the web sites I checked before purchasing. I can confirm that this thing is practically silent. My wife used to complain about the noise coming from my system, which I deteremined was the PSU. After installing this PSU it is impossible to hear it outside the case. The modular cables are very nice - first time I have had those - and made installation much easier. The only nit pick I can mention is that on the 520 model the SATA cables have two connectors on each cable; as I have three hard drives that meant I had to run two cables to that portion of the case. From the manual it appears that the SATA cables on the 620HX model have three connectors on each cable. Before purchasing a PSU check one of the online PSU calculators to see what you need - - I needed much less than I would have guessed. I used http://www.extreme.outervision.com/psucalculator.jsp

5 of 5 Great PSU Monday, February 18, 2008
A Customer from CT  
It does what it promises. This is a great psu for the price and it was more then enough juice for my new Q6600 build. I love the modular psu, it really helps with wire management. Would def buy again.

5 of 5 Does it's job. Friday, February 01, 2008
robush4@gmail.com from atlanta, GA (georgia tech)  
Seems to work well. Bought based on the overwhelming reviews and the fact that corsair has good customer service if anything goes wrong. they even scout out reviews that are negative and track down the reviewers in order to rectify the situation. also, the technical reasons i bought this are: 1.modular 2.has pci-e connectors (6 and 8 pin) 3.has 3 rails. with plenty of amperage for my needs. all in all, the price here was best, though still high for a PSU. however, the proce diff between a middle rande and this was minimal for the peace of mind that it bought. whenever I am buying hardware, i look at the price difference between the components I am choosing between, not the overall price. I feel this helps, if not just psychologically.

4 of 5 (almost) very good Monday, January 21, 2008
A Customer from Durham, NC  
Pros: - Compact, fits well in my P182. - It is as silent as I hoped it would be and delivers stable power (as it is supposed to) Cons: - The ATX/CPU 8pin cables could be a couple of inches longer. The CPU 8 pin cable was a tight fit in my case - PSU placed at the bottom and cable had to get to the upper left corner of the Gigabyte GA-790FX-DS5 mobo while being routed "behind" the mobo. Also, I had to install the PSU with the fan downwards - the SATA power supply plastic (at least) is flimsy - much less robust than the one that came with my Seagate retail-kit disk. I actually managed to "break" one. Unexpected and unpleasant surprise.
