Looking at the placard on the side of the Tagan SP-1000E
GuardianX gives you a pretty good indication of what this power supply is
capable of it fails to address some other things that just as important. For
example lets take a look at Over-current protection. If the current limits below
are exceeded the power supply will shut-down and latch off.
Voltage
Over Current Limit (lout limit)
+12V1
110% minimum; 150% maximum
+12V2
110% minimum; 150% maximum
+5V
110% minimum; 150% maximum
+3.3V
110% minimum; 150% maximum
If an under voltage fault occurs the supply will latch all DC outputs into a
shutdown state when the +12, +5 & +3.3V outputs drop below 85%.
Looking at the rear of the power supply you can see the 80mm fan and the
black colored fan grill that covers the opening. Some people might wonder
why the 80mm fan and not 120mm fam. I think the biggest reason they
went this route is the shear size of the power supply would have suffered if
they had of opted for a larger fan. In our experience of using the
SP-1000E for over a month the 80mm fan does a remarkable job of cooling this
power supply.
The front of the power supply has some serious holes happening
here, these holes will allow air to pass through the power supply and help keep
if cooler than normal. We did not have a means to check the speed of the
fan so we ended up using the WAG method of testing. Thanks to the clean
layout of the inside of the PSU the air will travel through the case without a
problem
Not much needs to be said about the rear of the power supply it has the
standard male plug-in found on most power supplies, below it is rocker
switch that turns the power supply on and off. Last but not least the
80mm fan and fan guard that will help remove the warm air from the power
supply.
With the cover removed from the power supply it is very evident that Tagan
is going to make absolutely sure that all of the high-end components are
covered with heatsinks to insure that they stay as cool as possible.
You can also see that the power supply has had extra care taken to insure
that all wires are carefully grouped together so as to prevent a tangle from
causing poor air flow through the case. Also of interest is the
extremely large capacitors that are used to filter the power supply voltage.
