Cons: - Many of the plugs are poorly fitted, in particular the 24-pin ATX connector will not go in all the way to the motherboard, while many others had to be given significant force to latch

Pros: + Completely silent for most of my computing, even while gaming+ Relatively small for a 650W unit+ Looks nice+ All black cables, no red, yellow and blue spaghetti+ Cables are plenty long for cable management in a mid-tower case+ Very well packaged and organized
The con is a major con for me, as getting everything plugged in was extremely painful on my fingers. I'm not also paranoid that the ATX power cable might have some issues since it is not plugged in all the way, but it simply will not go all the way. My previous power supply (OCZ ModXStream 600W) plugged in without issue.I can't imagine how bad it'll be when I have to unplug things for upgrades... plugging them in is usually the easy part, but getting this thing hooked up was a royal pain.The unit itself is efficient and quiet.. in fact completely inaudible powering an i5-4690K + GTX 760 under heavy load.

Cons: - had some trouble putting the cables in fully- would prefer more SATA cables than 4-pin molex

Pros: - 80 Gold- modular- silent
Overall a great PSU. The cables didn't fit snug though. I had to really push it in.

Cons: Flat cables, very hard to "dress" them in your case

Pros: Modular cables, very very quiet
Overall I'm pretty happy with this power supply so far. It's super quiet, and was pretty simple to install.My biggest issue is the flat ribbon cables, it makes it very hard to dress your cables inside your case.

Cons: none

Pros: - silent- fully modular- 80plus gold
Overall, this is a wonderful power supply; the fan doesn't spin until certain loads, this will have less dust accumulating underneath the power supply's filter when the computer is idle. The cables are sleek and fully modular which is great for cable management.

Cons: All flat cables

Pros: All flat cables, Silent, Fully back wires
This is a great power supply if you want silence. I put all flat cables as a pro and a con as they can be a bit hard to route if there isn't a straight path for them to follow.

Cons: Rebate is a scam

Pros: Great item at a good price.
Do not buy due to rebate listed on NCIX.com I ordered with the free ground shipping and received item too late to mail in rebate. When trying to contact NCIX I received an email response that instead of email they would chat online, but when you go to the online chat it is "unavailable". So, recommend the product just not ncix.com

Cons: SATA power cables all right-angle, cannot be used with certain drive mounts24-pin ATX power does not fit tightly in modular socket

Pros: SilentQuiet fan cools unit only when requiredEfficientLots of powerModularFlat cables
This power supply is totally silent under normal operating conditions. The effect on the total noise produced by my system is noticeable. For piece of mind, a large, quiet fan will run if the load gets high and the temperature increases, but my system may not even be capable of triggering this.It's very efficient, 80 Plus Gold with active PFC, which leads to less heat to begin with.This is my first modular PSU, I appreciate the space savings and cable simplification this brings. The cables are flat so they are relatively easy to press down to minimize obstruction.I have one very serious problem with this PSU though. All the SATA power cables are right-angle. This is disastrous in my Fractal Design Define R4 case with an SSD mounted below the motherboard - you will not be able to use a right-angle SATA power cable with this configuration. The SATA power port is keyed to come down from below but it's impossible to connect with the SSD flush against the motherboard tray.Fortunately I had an old Molex-to-SATA power adapter cable lying around. I ran a Molex line out to the adapter cable and on to the fan controller which solves the problem.My old Antec power supply had right-angle SATA power plugs along the length of the line but a straight-in plug at the end. All I had to do was use the plug at the end. I wish Corsair had done this!Beyond that major problem, a minor issue is that the 24-pin ATX cable will not fully seat in the modular plugs. There's just too much resistance, the catch will not engage. It's in tight so there shouldn't be a problem, but the catch did not lock in like the other lines did.If it wasn't for the SATA power cable oversight, this would be a perfect power supply.
