Alienware X51 R2 Desktop Gaming System Review

System Power Consumption

It was no surprise that the Alienware X51 R2 was pulling less power at the wall than our test system. The Alienware X51 R2 was sipping power at idle pulling only 44 Watts while the ECS Z87H3-A2X and Intel Core i7-4770K was pulling 64Watts. Loading up the CPU with AIDA64 Stress test the X51 system was pulling a peak of 94Watts while the ECS board was pulling 145Watts! Firing up 3DMark Firestrike and relying heavily on the NVIDIA GeForce GTX 670 the gap closes a bit but the Alienware X51 R2 still pulls 28 Watts less than the ECS Z87H3-A2X and Intel Core i7-4770K.
