Inac mal by si mat ku tomu zdroju aj manual kde na siestej strane je napisane:
4 The VX550W/VX450W has an 8-pin +12V; also know as "EPS12V" cable.
a If your motherboard has an 8-pin +12V socket, connect the 8-pin cable
directly to your motherboard.
b If your motherboard has a 4-pin socket, detach the 4-pin from the 8-pin
cable, and then plug the correct 4-pin directly to your motherboard.
