Seasonic Gold Series X-750 Power Supply Review

Manufacturer: Seasonic

Final Thoughts and Conclusions

View Full Size

Seasonic has once again taken a Great power supply and made it even better. The enhancements made to the X-Series 650/750/850W power supplies translate to excellent performance, high efficiency and the ability to operate in silent-fanless mode at lower power levels.  Throw in a 7-year warranty, a good assortment of all modular cables, really tight voltage regulation, clean DC outputs and you have one very good power supply!

The Seasonic Gold Series X-750 power supply is currently selling for $139.99 USD (Newegg.com, January 2013).

Are you going to review the x-850 too?

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.
