I have 6 years old laptop ,with overclocked 2 core cpu from 2.6 to 3.2 , rams overclocked from 1300 to 1600 which is bus's maximum, and 7200 rpm hdd , in it runs avarege on 90C , sometimes even around 110C 8 hours a day for 3 years . So decided to remove cd rom , add some extra cooling and overclock gpu too ,maybe finally I can kill it , but I found out that 35w is just not enough so I need to change psu . But I am not sure if just replacing it with 45 or 50 will work . I googled but couldn't find anything. So anyone knows how to do it ? Is it bios that decides what part need how much power ,or somehow else ?
