Final Thoughts and Conclusions
To stand out in today’s PC power supply market; a unit must really excel in the areas of performance, functionality and cost. High Power’s new Astro Series GD 1200W power supply performs well in some areas (like voltage regulation) and is more average in others (AC ripple and noise suppression). The Astro GD 1200W PSUs main features are having fully modular cables, being 80 Plus Gold certified for high efficiency, and it’s relatively quiet operation at low to mid power. While High Power claims the power supply starts out operating in silent mode, it’s really not silent as the cooling fan is spinning at all times and generating a little bit of air noise. Quiet yes, silent no. Personally, I like to have a power supply fan spinning all the time (although very slowly at first) to keep a little air moving through the unit. The build quality this time around from Sirfa is very good and the AGD-1200F PSU is constructed with high quality components (like all Japanese made capacitors).
The new High Power Astro Series GD-1200W power supply is currently available and shipping. The MSRP is $239.99 but you can currently find it at newegg.com for $224.99 USD (November 2014). This puts the Astro GD-1200W pretty much in the middle of the pack for value. You can find 1200W power supplies for less money and there are others available at a much higher cost. It’s a tradeoff between cost and performance; you have to decide where your particular sweet spot lies. Last but not least, we aren’t thrilled with a 3-Year warranty; a good power supply deserves better.
