I-Star TC-620PD3 Power
Supply Review
When
you look at a power supply these days you need to think about what
components you will be putting into your system. The current dual core
offerings from AMD and Intel consume higher wattages, that coupled with
a high end video card or SLI/Crossfire setup and you have the makings
for a power hungry system which will be the kiss of death for lower
wattage units. Lets take a look at I-Star's 620 watt PD3 unit and see
how it stacks up.

Nice clean looking unit, I just
love the ones with 120mm fans! They move plenty of air and are near
silent. The unit feels solidly built. It comes SLI/CrossFire ready
with the extra 12 volt rail. It comes with connectors for molex and
SATA devices as well as the ever present floppy connector. The main
plug can accommodate the 20 and 24 pin connector without a cheesy cable
adapter.

Specs look beefy enough, how will
the stand up to real use? Let't take a look.

I first installed the
TC-620PD3 as part of my review for the I-Star S8 Storm seen
here. To really push this power supply we will need a bit more
of a gaming PC.
The Install:
The test system is a Gigabyte
GA-K8N Pro-SLI motherboard running 2GB of Kingston Value ram. The CPU
is a SanDiego core 3700 AMD 64 with a Thermaltake SI-97A. Rounding it
out is a PowerColor X1900XTX video card and a Western Digital 150GB disk
drive. After a run using the nTune system stability test for 10 minutes
to place the load on the system we see how this unit performed.

The idle numbers look right on the
mark and comparing them with the bios readings shows that they are
accurate. Everything looks good, the only thing I would raise an eye
over would be the +5 readings, but looking at the current and averages,
they seem to be reasonable enough. Of course I will attach the
disclaimer that software monitoring is at the mercy of the sensors on
the board and how the system interprets them, so I'm not overly
concerned.
Conclusion
I-Star brings a solid performer to the table with
this unit, the 120mm cooling fan performed as expected with very low
noise. The factory sleeving on the cables is a nice touch. The voltage
readings were within the 2.0 spec and I'm sure applying a voltmeter to
them would prove this true as well. Still, the design is nothing out of
the ordinary which explains the low marks on innovation. It would have
been nice to have modular cables, especially when it comes in at $169
retail. Still a very solid unit with plenty of juice for power hungry
systems.
