testing, we looked at the voltages with the system under load. This is not the
most precise way of measuring a power supplies' electrical tolerances, and
to take load (see SilentPCReview.com to see what we mean) but
it does a good indication as to the degree of DC voltage jitter. It
is also something you yourself can check out in the BIOS. The results for the Antec
430W TruePower are shown in the table below.
The Antec TruePower 430W has its best features in what
you can't hear.
With Antec's "low noise technology" the fans rotate at slower RPM's when the
system is cool and extra cooling not required. Additionally, there are two special molex
power connectors which are for case fans only. In the past, a case fan
was simply connected to the power supply as you might any other hard drive, or device. Drawing the standard voltage it would rotate at full speed, and was often a
source of significant noise
even when the case temperatures were moderate.
The two special connectors on the Antec supply enable the power supply's variable RPM technology to also control the case fans. This helps to reduce the overall
noise of the entire
case, and not just the power supply itself.With a very comprehensive assortment of power connectors for both
motherboards and peripherals, the TruePower 430 is a pretty good unit for noise
