for the moment i have following harware in my case :
PSU : standard 300W
mobo (abit kd7a)
cpu (amd 2000+)
ram (2*256)
cooling (1*120mm + 4*80mm + 1*40)
HD (1*80maxtor)
vga (ati 9600SE) *has NO cooler on it*
i think thats everything i have to mention... i know this will probably look liek a stupid question to you guys but i'am realy new in PSU's. i know my pc will shutdown if my PSU isnt strong enough but i prefer to have enough voltage(or whatever) in reserve.
