The supplied AC adapter has the Model-No. FSP400-60APN. The electrical values are slightly different from FSP400-60MDN from, are in total But ok plug connections are plentiful (3 x SATA instead of 2 x SATA). Disturbing was the note "In enem 24pin ATX connector on the mainboard please squeeze the 20-pin and 4-pin connector and insert together in the socket on the motherboard." The mainboard (MSI 7204) in my Medion PC has a 24-pin connector, the old power supply but only one 20-pin connector. Now, if you follow the instructions, the PC does not start. So please note: If only one 20-pin connector was present before, then just do not plug the 20-pin and 4-pin connector together, but only the 20-pin. The 4-pin is then unnecessary. The power supply is now running smoothly and stable FSP400-60APN since 10.22.2014.
