all of my psu are seasonic.. ive purchased others in the past, thermaltake, corsair, and those have not stood the test of time as well as my seasonic.
my prefered psu
Seasonic PSUs have never failed me and continue to provide my workstations with clean uninturrupted power. They have easily handled the many brown outs I face daily at work and I have yet to hear the fan turn on. Thanks to Seasonic for making such great products.
Seasonics are the beefiest and most durable power supplies that can take on even 4x480 GTX SLI and my computer falling down the stairs while moving it. It still works!
