Attached with the power supply you find a manual, a couple cable tighteners, power cable and a bag where all the modular cables are stored. I personally like  the idea of having a separate bag for your cables, because without one they tend to be thrown somewhere and never to be found when you need them. At least with a bag all the cables are in one place. Small – but a nicely thought out detail! The power cable provided with our sample is EU cable, but customers outside EU should get a corresponding cable to their territory. The power supply itself supports 115V – 240V input voltages.

Modular cables are covered in a nylon-sock. In total there are 10 SATA connectors, 5 Molex connectors, one floppy drive connector, and two additional 8pin (6+2) PCI-E connectors. All cables are long enough for even the larger cases. Nexus edge, which is the largest case we’ve reviewed had no problems fitting with these cables.

The power supply itself is colored in matte black. There is a gold colored fan-grill attached in to it. Both sides of the power supply have NAXN stamp on them and you can see the wattage printed in it also. Our sample unit is 750W.

As you can see from the specifications of the power supply, ENM750AWT provides enough juice for even the highest end system SLI-system. ENM750AWT uses multiple 12V rails – which I personally don’t like that much – to provide enough power to the peripherals connected. Personally I prefer having one huge 12V line so you don’t have to think which connector to connect to your power hungry components.

Let’s take a look at the backside of the power supply. You can find the typical power connector and on/off switch located in the right side. To provide the optimal airflow through the power supply, Enermax uses coarse mesh to minimize objects in the way of the airflow.

There are five connectors for modular Molex/Sata cables along with two connectors for PCI-E cables. All the Molex/Sata cable connectors have same pinout – so you can plug the cables in whichever you want. Each connector provide 3,3V, GND, 5V and 12V voltages. The PCI-E /CPU / RAM connectors provide only GND and 12V.

Not all cables in the ENM750AWT are modular. Like in most power supplies on market, ATX, 4+4pin auxiliary, 8pin auxiliary and two PCI-E connectors are built in the power supply and not removable. Both PCI-E connectors are 6+2pin so they should fit in all graphics cards on market.
