Learn how to install a power supply today with these simple steps. With its big assortment of cables and connectors, a power supply unit PSU can appear daunting to hardware newbies, but PSU installation is often easier than most would expect. Look for the power supply cut-out at the back of the computer case - It should be located either at the topmost or the bottommost of the case:.
For tower cases it's usually easiest to place the case on its side, as then you can rest the PSU on its side. The PSU is screwed in place using four standard ATX case screw, make sure you can see all four before screwing it into place, as it is possible to get the PSU the wrong way around.
In this case the extra 4-pins can simply over hang the socket or some PSUs have a connector where the last four pins unclip. The oddly name ATX12V connector is specifically designed to power the processor with a clean 12v supply and should be powered from its own 12V rail.
