With our review of the Topower 520W Power Supply, you may still be left with some questions as to just how a PSU works, and what makes a good unit. Head on over to ZephirTech as they explain all this and more!

When you think about building a killer PC, do you spend a lot of time thinking about what power supply to buy? Probably not. If you have done your homework you probably know that today's components are becoming increasingly power hungry, and you should be getting something in the 250 to 350 Watt range...

 

Generally, though, most enthusiasts and system builders pick up a generic 350 Watt PSU... Some people have picked up through online forums and online PC builders guides that they should buy a name-brand PSU from a trusted company like Enermax, PC Power and Cooling, or Sparkle. Unfortunately, there are few that actually understand what sets a higher quality power supply apart from a lower quality one.
