Usually when building a system, the first thing I do is look at the user. If the user wants to do heavy gaming, lots of graphics or videos, the user needs to have a top tier system. However, if the user mainly wants a system to do e-mail, Internet, and some gaming, their system needs to be built with quality components, but it does not need to be top tier. Do you need a high end power supply in a system that mainly does e-mail, and Internet? Probably not. You still want it to be reliable and provide clean power though. ArrowMax has a new power supply, the PSF-500SP, which offers 500W of power as well as a PCI-Express power connection. I am going to see whether this is a good power supply to meet the demands of the modern computer.
