Experience: 20 Days
Well built.
Some coil noise, which I don't think was noticeable when I first installed it.
While considered by others to be quiet, it is the component in my pc that I can ear all the time. While certainly not loud, I was expecting a more quiet psu. Perhaps the unit i got is below average ...
Remains at same low sound level even under load.

Good quality, nice packaging
one of the best PSU around 500-600w range with 80 gold plus. Definitely worth the price.

Good quality,silent half-modular.
24 pins and the 8 pins are a bit small.
Overall its a solid product I cant remove a star for the small 24 and 8 pins since most of people will have enough length to plug everything with a mid ATX case or mini ATX.

Experience: 2 Days
Seasonic quality, looks great, feels solid, 80+ gold
does NOT come with 3pin male fan to molex connectors....I needed these for all the fans in my case.
Overall decent PSU, no longer-term experience yet. If you don't have enough fan connectors on your motherboard, and you have a lot of another PSU or buy some nGear (or others) 3pin to molex adapters......

550w from seasonic, great build, high price, if you have money to blow, and a low power requirement, get this.

Experience: 12 Months
Good power supply with the 80+Gold rating, helps cut down on the Electric bill. Comes with a neat bag that comes with the cables, zip ties and velcro straps. the twist ties came in handy as well
for the money you can get at least a 80+bronze/silver rated PSU with more output if you want more head room with your upgrade path, other than that its perfect for something like a mild gaming HTPC
For what you get it's good, clean power going through that won't make the magic smoke come out/burn your house down and saving you the headache of replacing damaged parts, Defiantly don't skimp out on the Power supply.

the Bag the cables and straps came in come really handy for storing the unused cables and screws.

Semi modular power supply
80Plus Gold
Good price
Quiet fan
None that I can think of
Very satisfied with the power supply, no problems with it since the PSU was installed.

-Cables seem thinner than usual might be my imagination
-Does not support dual GPU
I have owned this G550 for a month, so far I have no complaints. It runs fairly cool when loaded and even when the fan comes on my video card is usually abundantly louder. This is undeniably great value for someone who wants an energy efficient and silent beast of a power supply. The cables seem thinner than usual but as a result they are very flat and flexible making cable routing easier but I am not sure about it's duribility yet only time will tell.
This power supply doesn't support having two high-end GPUs but granted it only has 550W. I don't hold it against Seasonic because I don't really need it nor want it but I had to say something negative.
This truly reaches a new gold standard for cost-effective power supplies.

Well built
Not to long
Used this guy in my hackentosh build, fit in a Bitfenix Prodigy with little issue, Has plenty of power for an i7 3770, 4 hardrives + 1 SSD with power to spare for a mid range video card. The power supply has the main connecter attached but everything else is modular witch is fine. You need to use the attached cables in 99% of the builds anyways.
This was my fist Sea Sonic PSU and wont be my last.
