How to Power Up an ATX PSU without a Motherboard
Today I have a quickie guide on powering up a power supply without the aid of a motherboard. This guide is aimed at the user who needs just a little more power to get that peltier working or to get more fans in your box. A 250W may not be enough for those chores, so here we have a solution. Get another PSU just to power those specific components.

As most of you know, motherboards usually come with just one ATX plug. How that works is, the two pins on the row of your motherboard is usually connected by a momentary switch. To put it in layman's terms, the switch you press in front of your case causes a 'jump' in those two pins which in turn tells the power supply to turn on.
