Installation / Testing / Results
Installation of the Real Power 450 went
as easy as any other power supply, unit we got to the video card. As I mentioned
about the Molex connector, the easy grip tab will require some manipulation, or
you can just use the "Y" cord that came bundled with your video card. The cable
length and connector arrangement is very smartly designed so there isn't miles
of unused wires. The Watt meter fits into a 3.5 inch drive opening and there is
a very small set of wires that needs to be connected to the power supply. Again,
this wire is very smartly designed with plenty of length and with a small
diameter gauge as to not promote cable clutter.

Using
SiSoftware Sandra's Motherboard Information module, the above information is
displayed. At 0% CPU utilization the +12 Volt line is very low yet the +3.3 and
+5 Volt rails are exactly where they should be. The voltage set in the BIOS for
the CPU is 1.6 volts. I would call 1.58 volts to be close enough due to
the amount of fluctuation as a CPU draws more or less power depending on its
current processing load. While the CPU utilization meter may read 0%, Windows
processes and services vary the utilization rate almost constantly.

One of the
built-in features of Motherboard Monitor is a high/low page that shows the above
information. Current, lowest, and highest readings from the many
sensors and in our interest, voltage levels. The sample rate of
Motherboard monitor has been set to 10 seconds and was monitoring the system
from 4:00 AM to about 12:33 PM with a total of 3073 readings. During the first
hour, the system was used very little - performing only minor net surfing.
The remaining seven hours were spent crunching on a Prime95 Torture Test.
The utility voltages of +3.3v and +5v are within +/- .03 of their target
voltage. Ther 12 volt rail averaged 1.02volts higher than the intended setting.

The Human
Computer Interface (HCI) is one of the most unique mods that I have seen bundled
with a power supply. The HCI is simply an analog style meter that indicates the
total power in Watts (Voltage x Current = Watts / Power) that the Real Power 450 is
producing. Indicator marks are ticked off every 100 Watts with the red line
at the 400 Watt mark. This small meter fits within the 3.5 inch drive
bay of your PC enclosure and has its own small wire to connect it to the power
supply. The gauge is illuminated with a soft blue light and the swing needle has
a fairly quick response time. The needle shown in the picture above is
indicating just over 200 watts of power with the system specs referenced above.
Software running at this time was: Prime95 in a benchmark run, 3DMark 2003 in a
benchmark run and a hard disk defrag being performed, all simultaneously. The
Real Power 450 still has plenty in reserve to meet even this systems demands.
Conclusion
The 12 volt power supply readings
certainly peaked my interest. Sandra says one thing and Motherboard Monitor says
another. Being at the mercy of a motherboard's onboard sensors isn't always the
best way to see things as they really are. So, a multi-meter came into action
and I re-measured the power output across a Molex connector that was on a power wire-bundle that was in use, across a CD-ROM. The voltage with
only normal system processes in action (system mostly idle) read 12.31
and when a Benchmark routine was begun, to put stress on the system, the voltage
dropped to 12.29. The 5 volt side of the connector showed the same minute
change, actually increasing from 5.01 to 5.05 volts when the benchmark routine was initiated.
I call that a passed check.
The Real
Power 450 has a lot going for it. The easy grip Molex kits built-in are a very nice
touch, and the power meter certainly adds its own touch of class. Solid power
performance that, given the power meter readings, still has plenty in reserve.
The power is obviously clean enough to keep an Overclocked Pentium-4 chugging
along. The only thing I would like to see included on future revisions of this
power supply is a manual adjustment knob to raise and lower the speed of the
fan. Since the fan is controlled automatically by a thermal sensor, you will
still get higher fan RPMs when the need arises, but having a manual over-ride is
never a bad idea either.
