Dell Specific PSU
Alienware PSUs are specific to Dell Alienware and XPS computers in that they use one plug for everything. They are good quality and can handle the rated wattage, but you cannot swap this with an aftermarket PSU without having to rewire your Alienware case. The good thing is that when or if you have to replace it (if you can find one), then all you have to do is pop it out and plug your wiring harness into the new one. 

The following models have this style harness plug:
Alienware Aurora - version 1,2,3 and the ALX
Alienware Area 51 and Area 51 ALX
