PowerSupply Jitter Tests

For 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 ability 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.

Listed Voltages AMP Lower Voltage Upper Voltage Jitter
3.3V 28A 3.16v 3.24v 0.08v
+5.0V 36A 4.89v 4.91v 0.02v
+12V 20A 11.73v 11.73v 0.00v
-12V 1.0A 11.95v 12.03v 0.08v
-5.0V 0.5A 5.09v 5.14v 0.05v
+5.0Vsb 2.0A 4.89v 4.92v 0.03v

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 conscious systems.
