PC power supplies
A power supply must deliver enough power for the build, with a sensible margin for the graphics card. Its efficiency, shown by a certification, cuts heat and energy use. Modular cables make building easier, and a fan that stops under light load keeps the PC quieter. Choosing far more power than needed brings nothing except extra cost.
