Seasonic has
taken the best parts of its previous power supplies and improved
them for the S12D 850. Thanks to low noise, great power efficiency, and good
cabling, the company has made yet another power supply that worthy of pairing with a high-end
Intel Core i7 processor or pair of dual-GPU Radeon graphics cards.
One of the standout features of the S12D 850 is its 80 PLUS rating.
Under testing PCSTATS found that even under just a 15% load, the S12D 850 was able to
maintain an 82% power efficiency ratio. This will not only generate less wasted
power and save you some money on your hydro bill, you'll also cut down on excess
heat in your system as well.
Both heat and noise were also impressive. During testing the Seasonic
S12D 850 was barely audible, and remained cool to the touch over the duration of
it being put under load. The fan itself is automatically controlled by the case
temperature, so if your PC isn't under stress or load conditions and building up
heat it will remain nicely silent.
The Seasonic S12-850 power supply retails for a reasonable $180 CDN ($160 USD, £100 GBP), which is
a little less than you'd expect to pay for a high-quality PSU of
this capacity. The S12-850 also has all of connectors you'll need to
run multiple videocards and large RAID arrays without resorting to splitters.
Being that the Seasonic S12-850 is one of the most efficient power supply PCSTATS has tested, and given
the incredible increases in power consumption with top-end hardware
these days, the S12-850 couldn't have arrived at a better time. If you're
building a high-end PC system for gaming or number-crunching, the Seasonic S12D 850
should definitely be on your short list. Recommended.
