Pros: rock solid, no electronic noise, whine, etc
Cons: loud fan

First of all, this is NOT a modular power supply. Many reviewers on newegg and elsewhere don't seem to understand that concept and down vote it for that reason. Personally I used all but a few of the attached cords which were easily tucked away behind my hard drive bays. The sleeving on the cables is nice and they are a good length for my case.
One thing this unit lacks which I expected is a 4-pin motherboard power cable. Even my terrible quality Rosewill unit had one. However if this is necessary for your setup a molex to 4-pin adapter is available for about $1. My motherboard only recommends using it for multi-gpu configurations which I currently do not have.
Initially I thought the fan controller on this unit was defective because the noise level was so high. I even filed an RMA with Corsair but decided against that when I realized I would have to pay shipping. The included cooling solution is a Yate Loon D14-SH 12 140mm high speed fan. The noise it produced at idle was unacceptable, and surprising considering it is a large 140mm fan which generally operate more quietly than smaller fans. Upon further investigation I found that the fan was in fact going at about 30-35% speed. For reference it stopped turning at 25%.
Yate Loon makes a good fan, in fact that's all I am using in my system, and really there is nothing wrong with this 140mm fan. It has very high air flow at 100% speed, 140 CFM advertised, and has the most airflow of any fan I've had. It's just not suited to the application. I think Corsair reasoned that a large fan with really high CFM could run at really low RPM and be really quiet. Obviously this doesn't hold up, perhaps because the high RPM motor stops spinning at too high voltage, above the truly quiet range.
I replaced the 140mm with a low speed (47 CFM) 120mm Yate Loon, and even at full power load the air exhausted out of the unit is cool. The PSU is only bronze rated for efficiency but from what I have seen I think it at least matches other manufacturers' silver spec. When replacing the fan I admired the quality construction inside the unit. This is the first Seasonic made PSU I have owned, and I am a believer. I definitely recommend Seasonic products.
This review may seem overly negative but this is a great power supply. I would trust it to run well above the rated wattage and I think it would be an excellent choice for middle to high end dual gpu systems. This unit was overkill for my current system but I expect it to last for years to come. At an affordable $90, it will be hard to match the TX750 v2 for quality, current, and efficiency.
