Hi everyone- hoping someone can help me out.. I have an Asus G74-SX gaming laptop and had a major issue with my last power cord (the tip-chipped off)- so the A/C Power kept flashing on / off and I would have to tilt the cord to charge my computer. Ended up going into Best Buy and bought a new power cord (9v as opposed to the old one which was 9.5)... The new charger is working and the power is not flashing, EXCEPT for when I am playing Dota 2.. I am thinking it is because it is so demanding... Do you think it's the power jack, graphics card, motherboard, or power charger?? Someone please help I dunno what to do :(
 
As you've only had the problem since changing the PSU, logically, that will be the cause. Voltage is one thing, but did you also check the wattage? If you still have the old PSU, check how many watts it delivers and compare that to the new one. Chances are the new PSU can't provide enough watts to power the game and charge the battery.
