Seasonic Gold Series X-750 Power Supply Review
Final Thoughts and Conclusions
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).
Strengths:
• Outstanding voltage regulation
• Excellent efficiency across a broad range of loads (80Plus Gold certified)
• Low AC ripple even at 100% load
• Silent, fanless operation at lower power levels
• Very quiet operation at mid power levels
• Single +12V output can deliver up to 62A/744W
• Four PCI-E connectors (6/8-pin) and two 4+4 pin/8-pin ATX/EPS
• 7-Year warranty
• Active PFC with universal AC input
• All modular, flat ribbon-style cables with gold-plated connectors
Minor Weaknesses:

I would like to thank our friends at Seasonic for sending us the X-750 Gold PSU to review – thank you!




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.
