Seasonic's PSU's are excellent. The only brand I use.

Then you should maybe not judge things by their brand like a moron and start buying PSU's from other companies.

I have had this unit for a couple of months now and I have had zero problems so far. I got it at newegg on a super sale for $107.50 delivered to my door. It is overkill for my Sabertooth R2 8350 (4.5), MSI 7850 (1000 and 1250), 2 7200 rpm HDD, 1 Vertex4 128 GB, LiteON BD burner and 8 PWM fans. The most I seem to be using is a little over 350 watts and that is when I am ripping a BD disc and converting it to an MKV file about half the size. I had higher overclocks on both my CPU and GPU but I backed them down to a point where they run close to normal temps. I do believe that in order to obtain high stable overclocks you need a very good power supply and this is one.

I have this KM3 baby. Very solid power under load and keeps system running over minor power interruptions. (e.g. thunderstorms)

Really, really love this beast.
