Change MSI Gt70 Dominator power supply

Hey everyone !
I was wondering if its possible to change the standard 180 watt power supply of the MSi GT70 to a more powerfull one. Since I dont like how its constantly drainiing the battery to gather enough power for utilizing the GPU and CPU and also I have the feeling that the power supply is kinda bottlenecking the GPU (Gtx870m) correct me if I am wrong.
Thanks in advance.

 

As far as I know, the system is setup in a way that it won't utilize any extra juice you add to the PSU. That situation has been in place since the previous GT series with the introduction of the 780m series. The 180w PSU technically is enough to power your machine, but indeed when peak performance is reached, it will drain part of your battery over time.

I find it odd that you have this particular situation "constantly". I have the older GT60 with 780m overclocked to 880m speeds and I don't have my battery drained that much at all. I use my machine plugged to the wall and to an external monitor, so maybe the little power it saves from the screen helps me power through a bit more without always using the battery.

Edit: I forgot to mention that users have tested with 240w PSUs for my GT series and they found out the same behaviour as the 180w PSU.

 

Thanks for the reply I checked the energy draining sitatuon again and can conform that it really doesnt drain energy that often. I thought it would constantly because I always checked the battery percentage after I played games. One more question whats the point of using the 180 w PSU?

 

High capacity bricks are larger and require a new pinout.

 

Ok so they save money by using standard pinout for all models?

 

There's also not a real practical benefit for most folks to go to a larger PSU on this system. It would add weight, bulk, cost, and unused capacity for 99.9% of it's users. Even with heavy gaming and brightness maxed out I'm rarely drawing more than 150-160W with my GT70 w/ GTX870. It took running combined CPU/GPU burn-in utilities to actually max it out at 180W.

MSI's higher capacitiy AC adapters use a different pin-out, although other manufactures have managed higher wattage adapters without changing the pin-out. I'm sure they had a good reason though.

 

I've run some tests with 3DMark 11 and 3DMark Vantage and my machine. Uses up to 225-228 w on watt monitor on the wall. I also see that MSI has one setup with i7 4930mx and gtx780m (880). It can not be any good with a 180 watt power supply with that setup. There is impossible to overclock this machine. The Machine have not enough power. Also destroys the life of the battery. This is hopeless. Must have bigger power brick.

 

The max adapter rating for a 5.5x2.5mm jack is 180w, there are no larger ones.

 

Yeah, if the system really needs that much power, I could see a top-end config maxing out the 180W much easier. At least for my setup, i7/870m, it seems to be more than adequate.

I guess I knew that, but it's really more of an MSI choice to use that small 5.5mm connector on their notebooks. They could just go to a larger and more "standard" 7.4mm round connector that many of the big OEM's use. They've got AC adapters anywhere from 45W - 330W+ out there. Then they'd have a nice range of power supply manufactures that would be an easy swap without the need for adapters or splicing.
