Upgrading my laptop charger to go with new GPU

[Swango]

I recently upgraded my Alienware M17x R3 from a gtx 580m to a gtx 780m.
After playing games and loving the results, I noticed frame drops.

After testing, I noticed it's due to the new GPU throttling, and GPU-z reads it as a 'pwr' issue.

I've taken this to mean that the power supply isn't strong enough to run both the CPU and GPU at high loads.

If I buy a stronger charger to replace my 240w factory-provided one, will this solve the issue when gaming while charging? - Or is it not so simple with laptops?

i believe the 240w psu should be good enough for the 780m.it does use more power than the 580m thought.whats your cpu btw?maybe u need the 330w psu?

i suggest ordering the 330w adapter.for now try running the cpu without turbo boost and see if there is any differences.

Removing turbo fixed issue for now until I can buy better charger. Thanks!
