MSI GT70 (GTX 680M) - Where can I find a 220w+ PSW? - Cooling Mods?

[Turbosheild]

I am dabbling in overclocking, and I am reaching the maximum of what my 180w Power brick can provide.

My internal components are i7-3720, GTX 680M, Samsung 840EVO, 750GB Momentus HDD

I have searched, and cannot seem to find any power bricks above 180w. So, I am curious in regards to the possibility of splicing a higher wattage (220w?) PSU to the plug of my current 180w, 1) if this is even feasible, and 2) If this is a terrible idea than could cause damage to my laptop. Additionally, I would be greatly appreciative if anybody knows about a source for power supplies that run in the range of 220+ watts, and would be willing to share the aforementioned source with me.

Additionally, if anybody has done any aftermarket modifications to their GT70 to improve cooling performance, or any laptop for that matter, I would love to see, as I am hoping to do something of the sort to my laptop as well.

Any and all help would be greatly appreciated.

As long as the voltage on the 220W supply matches the 180W brick, which is 19.5V, then you'll be fine splicing that on there.

+1 on the cooling mods. I have looked around and haven't seen anything substantial. I kind of want to try changing to the "Cooler Boost 2" CPU heatsink, which has the extra heatpipe, but I don't know what real world impact this would have.

It's difficult to do after-market mods to cooling on these laptops, but I reckon if you had access to the right equipment you could match the heatsink's base dimensions and create one with larger area up top...

EDIT: The power supply MUST provide more amps than the current 9.2, otherwise it might it's 220W and just inefficient crap.

I do not have this laptop, but it seems to me that connection of both radiators (for example with thermal conductive silicone pad) would give a better result than the stock heatpipe thermal bridge between the CPU and the GPU.
