ok so here are the details... i know what causes this power save mode its whenever i higher my resolution on world of warcraft to about 1024x728 (not sure about number around there) .. my monitor will turn off saying entering power save mode. so ok i understand if i keep my resolution low i can avoid this but what i want to know is how to fix this problem. Do i need to buy a new graphics card to keep my resolution high or do i need to buy a new PSU (please new graphics canrd and not new PSU 
)
