The Cooler Master Real Power Pro 750 is painted a glossy black and it is
following the one fan design that is becoming common-place in most power
supplies we are testing lately.
Looking at the rear of the unit you will find a male power jack which is
used to provide power to the unit itself. Next to it is the On/Off
rocker switch and a single LED beneath it to tell when power has been
applied. The
Cooler Master Real
Power Pro 750W is compatible with the ATX2.2 spec standard and supports the
24 pin main ATX power connector. So a word of caution to those of you still
using a 20-pim motherboard the pins 21-24 are not detachable and there is no
24 to 20 pin converter included.
Also worth noting the
Cooler Master Real Power Pro 750W supports Active Power Factor Correction
(A-PFC) which improves efficiency, reduces heat and uses less power. A-PFC
circuitry eliminates the need for an external voltage level switch (115/230)
on the power supply since it automatically works with a wider voltage range
(115 AC of North America to 230 AC of Europe).
On the bottom of the power supply you will find the 120mm fan who's job it
will be to keep the power supply at a safe operating temperature. Of
course the Cooler Master Logo on the chrome fan guard add a nice touch to
the unit.
One nice feature of the Cooler Master Real Power Pro 750 is the fact that it
supports "Automatic Fan Speed Control", Exact CFM requirements
vary bu applications and end-use enviroment, but 60-80CFM is typical for the
120mm fan itself. For noise-sensitive applications, it is recommended
that a thermally sensitive fan speed control circuit be used to balance
system level thermal and acoustic performance.
Now let's take a look and see just how this power supply breaks down its
voltage. To start with we have 191 watts total on the 3.3V and +5V
rails combined with the 648watts on all 4 of the 12 volt rails. Then we
finish it up with 9.6w on -12V and +5V - 3.5volts.
