Rail Distribution

Although most PSUs that either have a single 12v rail that gives maximum power to all components but generates a lot of heat, or multi-rail setups that may not provide the required power to hefty components, the Corsair HX620 has a different way of doing things. It uses ideas for both camps and has a versatile yet stable way of dealing with its ampage distribution. There are three 12v rails which work independently if everything is going well – and gives motherboard, CPU and GPU their own rails – but if one component should pull more power than its rail can handle, “power sharing” is enabled through electronic triggering and the other rails help out their struggling buddy. This combats the heat problem on single rail systems and the stability problems with multi-rail systems; two birds with one stone.
