Cons: Two days ago I pressed the on button and nothing happened. I opened it up and checked to see what was the matter. I thought it could be the on switch. Couldn't get to the switch. Quickly put in a power supply I had around and the machine fired up. Put the Antec back in and it still wouldn't fire ...
Summary: Mine whined when the PC was turned off, was pretty annoying. Especially after spending 2 hours getting it installed and wired up nice. It's not the most quiet PSU around either at high load. I sent it back and purchased a Seasonic X-650. Still waiting for it to arrive...
Pros: Affordable, Semi Modular, DC-DC, fairly quiet, well reviewed
Summary: I went to my local Best Buy and purchased a Thermaltake power supply which I am not having problems with.
Pros: Cables are long to reach to the top of my large case (psu mounted on the bottom). 9 SATA power connectors was awesome (I used them all).
Cons: Just a day or two after installing it began to give an intermittent loud high pitched noise. I would have to shutdown the PC and wait a few seconds before it would go away. It could be heard throughout the house! I did some more research later to find that this was common with Antec power supplie...
Summary: As soon as I turned my computer off I got a very loud frequency noise that was coming from the PSU. When I would flip the switch from the back of the PSU off I could hear the frequency noise dwindling down. It didn't take rocket science to find out the souce of this problem.
Pros: Solid design, modular design, Antec brand.
Cons: High pitched frequency from a loose coil on this unit as soon as I turned off my computer.
Summary: Newegg usually rocks on getting replacements though!
Pros: All the features and price with rebate!
Cons: Arrived DOA. Booted for a couple seconds then died. It is terribble that I have to pay for shipping when the product doesnt work. This went from a great deal to a mediocre one in two seconds not to mention the down time wasted to get a replacement.
