Cons: 80mm fan, Rounded cables

Pros: Quiet, small, decent price point, Gold Standard, modular
Comment:
Not much to complain about this product. It does what it was meant to do and that's to provide power.If you're looking for an SFX power supply, this is pretty much the only one that's a Gold Standard. It's fairly quiet as I have version 2.0.If I had to nit-pick on this, I would have preferred flat cables as working with an ITX setup, rounded cables makes it much more difficult to route the cables. The cables that come with it are fairly rigid making it difficult to work with.The 80mm fan is decent, but time will tell how it will hold up. I wish it did come with a 92mm fan, but it may have been a space issue with the design.If you're building an ITX system, this is the only way to go!

Cons: Fan is more noisy than it should be during idel useage. NCIX is shipping ver 1.1, while ver 2.0 has supposedly fixed the fan noise problem.

Pros: Modular wiring helps reduce clutter. Small size. Relatively low noise but could be better, see cons. Fits in ATX case with supplied adapter.
Comment:
The model I received had a wire routed into the fan blades causing a terrible noise on power up. Luckily I was able to push the wire out of the way without voiding the warrenty seal, but it means that Silverstone is not testing these units before shipping since there's no way this unit would have passed.I was dissapointed to receive ver 1.1, it really is more noisy than necessary during idel - see other reviews about this problem. If you buy this power supply, make sure it's ver 2.0 or greater. The noise is faint, but could be annoying for an HTPC build. In another type of build it probably would be silent.I tooks away 1 star for quality (improper routing of a wire into fan blades) and 1 star for the idel noise levels. Note this is for ver 1.1, ver 2.0 is supposedly better.

Cons: Modular cables are too snug, fan rattles initially

Pros: Small, tiny, modular, powerful
Comment:
Got this for a SG05 case and I found that some of the modular cables are so snug that they don't "clip" into the thing they should and just dangle at the edge of it. Beyond that it works perfectly. When I first got it I had issues with the PSU because it made ticks but I shook it and the obtrusive fan noises stopped.

Cons: VERY tight fit in an ft03 mini but it was expected.Cable sleeving could have been better, but only corsair really gives premium cables with their power supplies so its not a big deal.

Pros: 80+ Gold RatingSmall cables for small casesAdapter included which allows you to install it in standard ATX power supply cases.
Comment:
This is the best SFX power supply you can buy. Amazing for mini itx builds.
