What kind of power output do I need for a fully loaded x1900 crossfire system?

post #1 of 5
Thread Starter 
I am looking to replace my piece of crap Antec TP-II 550 watt power supply with something that actually works and runs like it is supposed to. I really don't know what kind of power supply to get exept for the information the OCZ, Ernemax, and PC-POWER AND SUPPLY are good vendors. I know what the type of watts that I need but don't know how much amps on each of the pins that I need. I want to go out and buy a 700 watt OCZ power supply but it only has 36 amps on the +3.3V. Someone I talked to told me that I need at least 38 amps on the +3.3V and I have to agree because I am overclocking and am also looking into buying 2 more gigs of DDR3200 Supertalent ram. I am also running a fully cooled system with 3 80mm. fans, 1 120mm. fan, 1 slot VGA cooler, 1 aftermarket VGA cooler, a TT Big Typhoon VX CPU fan. I want a power supply that is going supply all these needs and have some left so that I can do some modifications later this year or early into next. Does it matter what amps I have for the +3.3V and the others as long as there is plenty of power(watts)?

The +3.3v and +5v rails don't matter as much as the 12v rail, whoever told you that you need 38amps on the +3.3v rail is flat out wrong

What is your budget?

My budget is around $100-$200 for a power supply. I need something that will allow me to upgrade without any worries of being without enough power.
