Experience: 3 Days

short cables for small cases, cables are all black, fully modular, very quiet.
Everything about this PSU is excellent. I have no complaints.

Experience: 7 Days

-more power
-fully modular
Was worried that I would get some coil noise after reading a few reviews of people getting it. The unit is next to silent that I can hear. I have it on the normal setting.
Retired after 6 years: Seasonic M12-500

I trusted going with Seasonic again after an excellent 6 years with my old PSU.

I needed more power for my HD 7870.

I guess I could have been still okay with the old one, but I didn't want to chance it as I was also overclocking the CPU and wanted to possibly overclock the video card some as well.


Experience: 14 Days
-very quite
-blowing cool air/efficient
-modular cabling
these are nitpicks:
-excessive packaging (canvass bag with velcro clasp for modular cables)
-the manual sucks (at the very least it should have a diagram with a list of the power output for each modular outlet). I don't like just trusting that if it fits, it works.
A power supply isn't really something that I would generally give much consideration to and I had only 2 requirements for a new one: quiet and durable.
This thing is silent for all I can tell - if I lean down to my computer, take the side panel off, I can hear the case fan, CPU fan and hard drive spin (if I put my ear close enough) but I don't think I can attribute any sound to the PS.
The air it is blowing is a lot cooler than my last PS. I'm guessing this is partly due to it's high efficiency (i.e. less power wasted as heat). At least that's how I understand it works.
Durability - In my experience power supplies and hard drives seem to be the first components to fail in a PC. 7 years is an extremely long warranty for anything these days. I'm hoping the fan on it stays quiet over the years.
