To follow
up on the success of the Real Power 450W PSU, Cooler
Master has released the new Real Power 550W SLI.
It complies with both the Intel standard ATX 12V
V 2.01 and SSI standard EPS 12V V2.1. They recommend
the Real Power 550W as a viable solution for high
end workstations and gaming rigs that contain those
power hungry dual graphic card solutions based on
SLI or Crossfire technology. The Real Power 550W
PSU has dual output connectors for PCI Express VGA
cards and has intelligent fan speed control and
“real power" capacity that will help
to maintain the stability and reliability of your
computer system even at the most demanding moments.
As with every
item we receive from Cooler Master, the packaging
of their products is top notch. The Real Power 550W
PSU even has a handle on the package to make transportation
a breeze. The contents come tightly packaged in
an “egg crate” that contained everything
required for installation as well as a small 3.5”
front panel display unit that shows the total power
consumption your system is using in real time.

The casing
of our review unit is polished black enamel; this
type of finish looks great but is notorious for
showing fingerprints. The Real Power 550 has a 120mm
blue led fan to exhaust the heat created by the
PSU. The fan will help draw and exhaust some of
the warm air out of the inside of the case as well.
Power supplies
like the Real Power 550W SLI include a circuit board
that contain thermal sensors. This heat sensitive
circuit board controls the speed at which the fan
spins based on the temperature recorded by the thermal
sensor. This effectively manages the power supplies
heat and noise levels.
The rear
panel of the PSU is a steel mesh honeycomb style.
This honeycomb design is efficient when it comes
to exhausting heat from inside the power supply.
The two side
panels of the power supply contain the usual stickers
showing the unit output specifications and the relevant
cautions regarding the dangers associated with opening.
