    Hello,

    I have done a lot of research before attempting these two upgrades, but I have a few questions so that I can avoid damaging anything, maybe someone here can help?

    I understand that the TDP for the 980m is 125W and the TDP for the i7-2960XM is 55W. My current charger is capable of 180W, so I just want to confirm that I am correct to purchase the 230W MSI charger that goes with the GT72 Dominator Pro? Is there anything that I need to consider if using a charger that is not designed for my notebook as long as the voltage is the same?

    For someone who has specific knowledge of the parts that I mentioned: my current MSI BIOS version is E1761IMS V1.0B, the 980M is an official MSI card (non-SLI) and as I understand it, this should be plug-and-play. Is there anything else to consider?

    If I make sure that the 230W charger can handle the required 180W TDP, is that everything in terms of power considerations? Do the other components have a TDP to consider as well? Is 230W enough or do I need to go even higher?

    Thanks for any help you can provide!

    IIRC, the 980M has a tdp of 100W, but again, like the 2960xm, if you OC it, the tdp will go up. Other system compenents should amount to ~30W give or take in total power draw, so yes the 230W charger was a good idea.

    Thank you Grant,

    After more research it seems that the MS-1761 (GT780DX) cannot go over 180W - so if I bought the 230W charger, I would see no greater benefit. Can someone confirm this? I am not concerned with overclocking the CPU, and any GPU overclocking would be minor so do you think that the 180W should cover me?

    Thanks

    It would be slim, but it should? 30W+~55W+~100w=185w I don't understand what you mean it can't use the 230W adapter, but the 180 should be alright

    Due to the EC controlling wattage I think it doesn't go over 180W, perhaps just some Watts.

    The GT780DX has something called NOS, which due to the EC firmware limits the TDP...but, I understand that you can go a little bit above 180W if you have the battery attached because it will pick up some extra power from that.. Can anyone confirm this... @Meaker@Sager or @omega939 maybe you can help? Thank you

    Yes i can confirm that u NEED the 230w power supply. No. There is no problem with wattage over power the motherboard. Or any throddling. I have built over 30 msi gt660 ms16f1 through ms1763 gt70. I have built a gt685 with the 2960xm and the gtx980m. It runs at 4.1ghz with auto turbo. For some reason the turbo button no longer worked maually. We thought this was odd but when it reached 3.8 it auto selected it and the turbo button comes on and it goes up to 4.1 to 4.3ghz . we use core temp to monitor temps and speed. I personally have a gt660 with a 920xm 55w chip and a gtx 880m 122w gpu. That 980m will run about 118 w at peak performance. U should definitely buy the larger power supply because lack of power is a major no no. Just look on ebay for a 230w brick with a 5.5 by 2.5 tip. They are around 35 to 40$.

    Thank you, but I'm still looking for a definitive answer on this subject. Many people here have told me that my model (MS-1761 / GT780DX) will never draw more than 180W. I think the exception is that because of the NOS feature, it may go slightly over that with the removable battery connected. The 230W charger I'm told will do nothing for me because the system does not know how to use the extra power... unless you know something different? Please describe how the MS-1761 could take advantage of the 230W
