The FSP Twin PRO is a redundant power supply unit, which is designed for standard ATX or PS2 housing. No front-end holding device is required. Perfect for email, web or home servers. The hot-swappable design of the modules ensures a stable power supply. If one power supply unit fails, the other power supply unit immediately takes over the complete power supply. From now on, you don't have to worry about a power interruption in PC/server operation. https://elecena.pl/product/18617521/ppa5008601-fortron-twins-pro-500w 2021-05-29 https://elecena.pl/product/18617521/ppa5008601-fortron-twins-pro-500w 2021-11-13 https://elecena.pl/product/18617521/ppa5008601-fortron-twins-pro-500w 2022-07-26 https://elecena.pl/product/18617521/ppa5008601-fortron-twins-pro-500w 2022-10-26 https://elecena.pl/product/18617521/ppa5008601-fortron-twins-pro-500w 2024-07-15
