SilverStone Element power supply series is being out for some years now, and we were curious to review their popular 500 W model, ST50EF-Plus. It is important to know that models from SilverStone Element series can be manufactured by two distinct companies: models up to 600 W are manufactured by Enhance Electronics, while models starting at 650 W are manufactured by Seventeam. SilverStone uses a lot of different manufacturers for their power supplies. Besides Enhance and Seventeam, units from their Decathlon series are manufactured by Impervio and units from their Strider series are manufactured by FSP. Phew!
