1 out of 5 eggsStupid Stupid Stupid

Pros: Antec always fulfills their rebates

Cons: Fan on this "Bottom mount" model runs in reverse!
Obnoxiously loud fan that runs all the time.

Other Thoughts: Had this P/S for a few weeks before I realized the fan is designed to be bottom mounted only!

Newer model Power supplies should specify "Top Case mount" or "Bottom Case mount".

In my top mount build, hot air draws in from the top outside and is forced right back out out the case main evacuation fan right below it.

I used to pay top dollar for Antec because of dependability and quiet fan or no fan under normal load. Much more expensive to manufacture a high current power supply with no fan under low loads. Later Antec models, including this one are designed with cheaper components that need constant cooling for higher rated output.

4 out of 5 eggsServed its purpose

Pros: Quiet, no problems during its life

Cons: Purchased in 11/2011, failed this month. So, pretty decent and could still be under the 5 year warranty.

Other Thoughts: Glad it lasted longer than 3 months as some reviewed..probably won't purchase Antec PSU anymore.

5 out of 5 eggsUnmatched quality

Pros: Unmatched Antec Quality. What else is there to say? The case is attractive. The packaging was out of this world and this supplies a stable and steady stream of electricity to my home KVM test lab.

Cons: Not a modular design but I knew that when I purchased it.

Other Thoughts: I really liked how the power supply was packaged. It came in a very nice box and wrapped in a bag within that box. The presentation was nice and made me feel great about my purchase.

5 out of 5 eggsAmazing PSU !!!!!

Pros: What an amazing power supply this has been. I don't know what all the negative reviews are about. I've had this PSU in my PC for almost 4 years and have had no issues. Actually just about to replace my sister's (she has my PC now) GPU and RAM and this supply is still running strong.

Cons: -none
-bout to throw a 750 superclocked and another 8 gigs at this old girl.

5 out of 5 eggsMy thoughts so far

Pros: Intel Haswell Certified, active PFC and high current to ensure power hungry video card gets what it needs.
My first thought when I picked up this power supply out of the box was literally, OOOFF! This thing is heavy! Easily one of the heaviest PSU's I have ever picked up.

Other than that, its great so far, and especially for the price.

Cons: weight!
its not modular, but then again, I paid 129.99 for 900 watts.
