Final Thoughts and Conclusions

Seasonic has once again taken a very good power supply and made it even better. The enhancements made to the X-Series XM2-1250 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 great assortment of all modular cables, really tight voltage regulation, clean DC outputs and you have one very good power supply!

The Seasonic X-Series XM2-1250 power supply should start entering North American retail channels in August 2014 with an expected MSRP of $239~$249 USD.

•    Up to 1250 watts continuous power output
•    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 (Hybrid S3FC Fan Control)
•    Seasonic X-Series DC Connector Panel with integrated VRMs
•    Single +12V output can deliver over 100A (1248 watts)
•    Ten PCI-E connectors (6/8-pin) and two 4+4 pin/8-pin ATX/EPS12V
•    7-Year warranty
•    Active PFC with universal AC input
•    All modular, flat ribbon-style cables with gold-plated connectors
•    Very competitive pricing

Minor Weaknesses:
•    Not available in NA yet, but coming soon! (August 2014)
