Review: literally worth every single penny i paid for it and more - The was one of the best purchases i have made in some time, so far i have this, a passive cheap gt 730, a passive zalman fx100 (horrible to install but great when its done) and a silent series corsair case. This build was for my girl because her pc has a bad psu in it before that was loud no matter what you were doing and i mean loud like air conditioner loud... but now you literally cant even tell the pc is even on. I was so impressed that i am now making plans to build myself a passive silent gaming box utilizing the accelero cooler with an rx 470 and a passively cooled i5 6600 in the same case as her with this same power supply. I will say that YES there is gonna be some coil whine because this thing is being punished in her build by an old 95 tdp i5 that literally sits at like 80 watts thanks to its age. but other than that its great FYI the coil whine is barely noticble and completely unnoticable with the silent case so yeah its just wonderful to do use a powerfully fast computer with no noise to bother you in the back ground. 10 stars if i could award it so! Silverstone, keep doing what you do! cause you doin it right!
Review: Quiet, but gets too hot in an HTPC case - Used this in my HTPC slim case to reduce the noise (PC sits 2 feet from my seat in the family room). Totally quiet, but when I touched the side of the PC, it was too hot to touch. Ended up returning it before it damaged the PC components. The HTPC case (Moneual 320) may not have sufficient air flow to cool the power supply, but this is the exact application where a quiet power supply is needed.

### ⭐⭐⭐⭐⭐ A fine power supply
*by M***N on November 17, 2012*

Just installed this beauty into an older rack mount PC. The aluminum frame is solid and the set of connectors were more than needed. Four screws bolted PS into place into the 3U case matched. Good documentation.
