The MGE Extreme Gamer (XG) Magnum 500W PSU is a totally silent and
powerful PSU. With the fully aluminum housing, internal heatpipes and
multi-direction air ventilation which will provide the optimum cooling
solution for this PSU yet silent. With the dual 12V rails of power, it
will support many peripheral devices without any problems. The downside
for this PSU is the sleeving is not very good due to it was not fully
sleeve to the end of the cables and this PSU is not SLI ready as well.
This was a good buy power supply unit if you are looking for a powerful
and nice looking PSU although it was slightly expensive than other normal
PSU.
