Magnum 600 External seems to be a great product. Its aluminum case helps dissipating its heat and its fanless design is a plus for helping lowering the noise level produced by the PC, but your PC won’t be completely silent, since you still have fans on the motherboard and video card (and maybe extra fans on the case).
Since it is an external power supply, it should help lowering the PC internal temperature.
Its LCD panel is really awesome, since it shows not only the power supply temperature and voltages, but also the power that is really being consumed by the PC.
It carries two PCI Express auxiliary power connectors for feeding two high-end video cards, running on SLI or Cross Fire configuration, which is great since you don’t need to use any kind of converter cable.
Another important feature is that it has two separated 12 V rails, i.e. these two 12 V outputs are produced using two different circuits inside the power supply. Usually when we have two outputs they are simply a division of one rail (i.e. output circuit) inside the power supply.
Making the math to check if this power supply is really 600 W or not, a surprise. Its maximum power is of 650 W, accordingly to our calculations (5 V x 30 A = 150 W + 12 V x 18 A = 216 W + 12 V x 22 A = 264 W + 12 V x 0.8 A = 9.6 W + 5 V x 2.5 A = 12.5 W). To learn how to do this math, read our

The only constructive criticism we have to MGE is to use only one name as the brand name. Using MGE and XG at the same time is confusing. As you can see on Figure 1, XG is the brand name on the box, but on the power supply itself the brand used is MGE. Even though XG is a brand name of MGE, the vast majority of users don’t know about this and can question if they bought the correct product or not.
