Summary: A power supply should just work. This has one has given me problem free operation for over three years. It is quiet. The cables were adequate for a everything I installed in my mid-tower atx case. All cables had mesh sleeving that makes for a very clean and neat installation.
Summary: having a power supply that cranks up the fan when it gets hot is not a feature, it ANNOYING. Thing rattles around vibrating inside and outside my case. Fan control is unnecessary and sounds like a jet engine when it gets hot. If the thing just had normal fan speeds it wouldn't do that but since it's OFF until it reaches a certain temperature the fan powers up for 2 seconds of cooling then shuts back off. This is not even adequate design.
Summary: The SATA power cable did not reach the far end of Corsair 650D to plug in my two storage drives and disk drive. Not a major problem, $7 molex to SATA fixed that issue. I would get it again. This cable is also NOT fully modular, it does not show in the pictures but it does have a non-modular bundle and no extra SATA cables. Great product though, silent in my use, and looks just fine in my case. More power than I'd ever need.
Summary: I had expected that all of the cables would be detachable from this PSU, but that is not the case. Only about half of them are which is really disappointing when doing a build in a SFF case. My last build with a SilverStone modular PSU allowed me to only plug in the cables I would actually need and thus, making for a much neater build.
Summary: Bought this Power Supply over a year ago. It looked great. I plugged it in and all was fine. It went into my son's new computer. In about 6 months, my son reported strange lock-ups and restarts. After a few weeks, that computer would not boot. It looked like the motherboard. I put that computer off to the side while I picked out replacement parts (and saved up some money). My son (without telling me), decided to move the power supply to his working computer.
Summary: I plugged this in and immiediatly paniced because the fan wasn't turning... Did some research and its normal...its that efficient. So don't panic if it isn't turning when you computer Is idle. I am pulling 1050w @ the wall with a killawatt with this beast and it doesn't hic-up. I did test to make sure it would shut of if overloaded, and it does. Keep in mind power @ the wall is not power being pushed out by the Powersupply, as the PSU uses power too.
Summary: This was a perfect fit for my budget build - didnt want overkill but wanted something that would last a few upgrades for video cards and whatnot. It hasn't failed me once and has been solid with my overclocked i7 950 and gtx 570 graphics card. Quiet. Getting ready to update to a gtx 770 and think it will handle it just fine...we'll see.
Summary: Does a really good job, it will be loud at first then quiets down. I believe that is normal because it is powering up. My old PC was also like that and contacted Corsair they said it's normal (I hope). I really like the PSU however the cables it came with might be too short for other mid-size tower. Mines barely reached, but since it reached it got a 5 star.
