Long story short i maxed out the stock 180w pretty fast switched to the spare 230w and again maxed that out so i will be looking for a 330w here shortly to finish my bench runs.
Few things even when the system was getting full power before i passed that fine line the temps were never over 70c and before i hit the point of taking way more power then the psu's were pumping out i did meet up with some GTX 680m's. Then i pushed it some more and the scores took a nose dive lol. Clocks were all 100% stable but i cant say for a fact the 1500 was stable. It ran but from the score i can tell it was not getting the power it needs so i can only say the 1450 was stable since that was my last full power run.
Official scores will not be uploaded or published until i have finished if i decide to.
On a side note this is by far the best nvidia gpu i have ever had. And to be honest it beats my legendary Q6600 i had and thats really saying a lot. So much so that i decided to buy this system just because of this beyond golden sample GTX 670MX that is in it.
Also dont mind the 2gig stick i had it sitting on my desk for a few months from a system upgrade for a guy so i just thought i would slap it in and make some use out of it.
Also if anyone was wondering the memory starts to get slight artifacts at 2650mhz

So that's all till i get a 330w psu here. I dont feel like modding the one from my MX18 so it could be a week or so before i post some stable max balls to the wall benches that bridge that gap between the GTX 670MX and a GTX 680m with a slight overclock. Really pushing to hit 1700 on this gpu but if i can only get it stable at 1450-1500 im happy with it.
PS. As you can see this is why systems with GTX 680m's come with bigger and better psu's. I maxed out that 180w stock psu pretty fast.

Thanks for the input. My question would be:
If I keep my G75VX CPU at stock with 2 RAM sticks, 750HDD plus one SSD, what would be the highest clock/voltage that the 180W PSU could handle on the GTX 670MX?
And one more thing. I noticed that the ASIC quality is 83%. Some MSI laptops with the same card but with 1.5GB of VRAM can get to higher clocks at default voltage while having an ASIC quality of 73-75%. How is this possible?
Thanks.

I started looking for some 330w psu's. Found a few online i'll go ahead and order one Monday and i should have it Thursday or Friday. Depending on how we are doing in heroics this week i might be able to push it that weekend or it might have to wait until the week after.

Any tunable voltage power supply (i.e. with a knob) with enough Wattage will do: remember, DC is DC. I've even run my laptop from a 1200W tunable unit in our physics shop with no problems. Just make sure your polarity is right (i.e. + to +, - to -). Go to your local Physics or Electical Eng. dept. at a college or university and borrow a tunable unit. That way you'll never be at a loss for power.

Thanks once again. The MSI laptop and my G75VX were OCed with Nvidia Inspector running the same drivers.
The MSI went to 820Mhz max while mine hit the wall at 760Mhz. A huge difference.
OK looking forward to see your results.
PS. Regarding the PSU testing it would be interesting if you could do it. Although personally I would be most interested if I had the ability to OC much higher. Otherwise whether it has a max of 150 or 180W makes no difference.
For me it will only be possible if I have the chance to learn how to unleash the GTX 670 MX.
