Small weaknesses in quad-core CPUs

I use the dock for 3 months with a Lenove Edge E540 (Core i7 processor), a 24 "monitor which I connected via HDMI and Windows 8.1. All in all I'm very happy. It could use some more USB be ports. The housing acts on the photos much larger than it actually is.

One problem is that to small-sized power supply (65W) for me. Under full load the power supply with 65 Watt is not enough to load the computer - that is, in this case, it switches off at some point, because the battery is empty. The standard power supply of the computer has 90 watts. The (expensive) Pro variant of the dock has the 90 watt power adapter and should be able also under full load to charge the battery (I could not test).

Pro:
- Small housing
- Fast docking and undocking
- Under Windows 8.1

Cons:
- A little bit USB ports
- Power supply with 65 Watt with slow performance for Quad-Core CPUs

Conclusion:
Good value for money, better for quad core take the Pro version.
