What can I say about the Cooler Master 850W power supply?
For one, I was quite impressed with its stability during CrossFire
testing. It isn't often that we see a power supply that has such minor
variations between its idle and load phases. That being said, the
Cooler Master 850W could defiantly tame even the most demanding of
rigs. Whether it be CrossFire or SLI, the Cooler Master RS-850-EMBA
screams "Bring it on!"

The Cooler Master Real Power Pro 850W PSU impressively dishes out
constant power during our benchmark test. 4 PCI-e connectors may be
considered by some as overkill but for gamers who want to power an
8800GTX SLI setup,they are necessary.......

With each successive generation, the power requirement of a typical
enthusiast's PC goes up another notch. The emphasis today for
processors may be on thermal efficiency but adding more cores to the
equation is also equally popular, leading inexorably to an increase in
power demands. AMD's quad core 4x4 platform is an extreme example of
such a trend and makes power supplies (PSU) of 1KW and greater, a
necessity rather than a luxury. Such a scenario is probably more
pronounced for the graphics scene, where two GPUs in a system is no
longer the cutting edge. We now have quad GPU configurations, thanks to
NVIDIA's Quad SLI technology and that means up to four high-end power
hungry graphics cards. The usual answer to such escalating power
requirements - higher wattage PSUs.
