slient, great functions
i always pick seasonic.

Experience: 1 Years
-Fully modular
-80plus Gold
-Fancy packaging
-Dead silent in hybrid mode
-7 Year Warranty
-Buzzing sound when PC is off but PSU still on
-Died after 1 year
I bought this PSU because Seasonic is supposed to be one of the best and all the reviews I read were raving about it. Apart from the annoying buzzing sound when the PC is off but the PSU on, it worked great and was dead silent. I've had this PSU for only about a year and suddenly died while I was in the middle of playing a game. I'm currently using my 5 year old Corsair 650w which is still going strong while I RMA this to Seasonic, hopefully the replacement PSU will last much longer. I probably won't be paying the extra to buy a Seasonic PSU after this one.

Quiet running
Hybrid fan control
So far seems to be a good quality unit.

Comes in fancy packaging with a velvety bag which contains the psu unit. The cables are flat ribbon style except for the 24 pin which is sleeved. The length could be more, they are just long enough for my P280 case. The 8 pin cpu cable might be a bit short for super towers with a bottom psu mount.

The hybrid fan switch works well, with my system idling the fan doesn't turn on at all. In normal fan mode the fan is super quiet at idle and light load.
