The Lepa G650 is one of those power supplies that many could benefit from. Even with some of the high-powered video cards being released, huge wattage power supplies are not really needed in most cases. Cards like the Nvidia GTX 580/670 as well as Radeon HD 7950/6970 would do just fine with this 650 watt power unit. And not only do you get the benefits of the power but the efficiency as well. At the Gold level there isn’t much more than could be asked for in a power supply. Ok, there are the Platinum units but at what cost. And what else that matters is in order to get to the Gold standard Lepa use high quality parts and components to get there.
