Installation:
Installation was quick and simple for this power supply. As illustrated in the diagram below it's very compact, even slightly shorter than a standard size ATX power supply. This certainly makes things nice when squeezing it into tightly packed, small size ATX towers. I was disappointed to see that Nexus chose to not include both a power cable and installation screws. For most enthusiasts this isn't a problem because we have tons of spares laying around, but I foresee this being an issue for general home users who won't have quite the hardware and parts collection on hand. When replacing an existing power supply you will already have the necessary parts as well from the old supply.

Testing:
Testing Disclaimer: To truly test a computer power supply to it's fullest extent would require equipment far beyond the budget of any part time reviewer. For that reason, our power supply tests are simple real world tests done by measuring it's performance when running in an above-average computer system as well as observing overall noise levels. Since any good power supply should be able to regulate it's voltages, I never expect to see much of a change in terms of voltage measured. Therefore, the testing portion of our power supply reviews should be taken as some overall, real world feedback on the power supply.

I decided the Value 430 would make a great addition into a Pentium 4 system another family member of mine is using. Being the only system in the house that lacked a high efficiency power supply, it was a match made in heaven. System specs are as follows;
Intel Pentium 4 2.6Ghz with Hyper Theading
1.0gb PC3200 RAM
2x100gb and 1x100gb hard drives
1xDVD Burner
1xATI All-In-Wonder 9600 graphics card
Nexus Value 430 power supply

Showing signs of a good quality power supply, the voltages remained stable at 4.99V, 12.18V and 3.42V under both idle and load situations. Without using testing equipment far beyond the budget of this site, we don't have a way to properly bring the power supply to a 100% load situation (system load does not equal 100% power supply load as some sites think).

Noise levels were just as impressive as the Nexus charts show. When the system was powered up, I couldn't hear the Value 430 over the noise generated from the CPU cooler, GPU cooler and hard drives. Stopping all the fans with my hand and allowing just the hard drive noise and PSU noise, it was still nearly inaudible in this sytem.
