How much can one power unit handle?

[Lunatic_Freak]

How do I determine how many fans,drives,etc many power unit can handle? Is it adding up the amp's?

ok, well i have a 300 watt psu that came with my enlight case...this is running my 1.33 right now(at stock speed) a cd-rw drive, 2 80mm fans, blue orb, 1 92mm, and my thermoengine heatsink fan which is the 7k fan, floppy drive, and my motherboard.....i have most of the on-board peripherals turned off and the damn thing still restarts every once and a while under full load....so my guess is, (if you have an amd chip) go to the amd website, and they have a chart that will tell you what kind of psu your speed of chip will run with......if it says 300, get a 400, and if i says 350, get a 430w. you prolly get it tho...ill look for the link real fast tho

Make sure you add 2.5 watts for each usb device plugged into the mobo. Self powered hubs don't count.
If the total is within 75% of a psu's rating, go up one size higher.

get a enermax 350watt or 430watt and you should be able to run anything you want without a problem
