Equipment Cost - Conclusion

In this article I described the necessary equipment needed for a proper PSU review and the most significant tests that a reviewer should run. Nevertheless each reviewer follows his own methodology but in general most of us run some common tests (e.g. voltage regulation and efficiency at 20-50-100% load, ripple measurements etc).

In the following table you will find the equipment that I currently have in my possession. From the list I omitted my DSLR camera (Canon 500D with Sigma 18-200mm lenses).

As you have probably noticed by now PSU reviewing is a complex and pretty expensive hobby, and even if you have the necessary tools, you need to have the proper electronics background too, at least for disassembly and to provide an analysis of the internal components of the PSUs.
