Conclusion
With the SS-1050XP3 Seasonic
released an absolute high-end power supply. There is a costly AC filtering stage, an extremely high end fan, and
the massive use of Nippon Chemi-Con capacitors, which - amongst other parts -
add up to a great product. All the components mentioned comply with highest
standards and its hard to find other PC PSU's which are built according to similar
guidelines.
Furthermore this PSU is very reliable even if you plan with it for long term usage.
Compared to the predecessor Seasonic decided to add adequate cooling for the 12
volt mosfets on the back of the PCB, which means, that nothing will be
overheating even if you drive this unit above specifications. The manufacturer
is actually under specifying this unit, since it can cope with loads of 1200
Watt without breaking a sweat. Should you be building a high-end system, that is
to continually pull around 1000 Watts, this extra headroom is going to mean
piece of mind to you.
This high-end power supply is absolutely worthy of receiving five out of five
stars.
