This is my Power Supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171018 My Computer: Dell Dimension E521, AMD Athlon 64 X2 4200+ ~ 2.2 GHZ, 2x512mb DDR2 RAM, and 1x1gb DDR2 RAM = Total 2 GB (All DDR2 RAM at 667MHz), Nvidia 8800GT, 3 USB's in use (mouse, keyboard, printer), standard 16x DVD-RW Drive, 250GB Hard Drive @ 7200 RPM, 22 inch Westinghouse monitor, one 120mm Fan using 1.4 Volts on 12volt rail, one 80mm Fan using .14 volts on 12 volt rail.

Multiple Answers would me MUCH appreciated go here to find out.Listen to Homer.

(Does that COUNT as multiple answers?)

Use that to get a rough estimate of what the power requirements of your PC are. Don't be AFRAID to add things that you're not sure you have now or you might upgrade to in the near future. It's better to have too much power now than to get a PSU that won't supply your future needs.The eXtreme Power Supply calculator only calculates total WATTS. I know i have enough watts. I need to know if my Power supply's 12 volt rails are good enough to handle what i have for my Rig. If anyone bought the eXtreme Calculator that gives amerage. Can u help me out? ALSO, anything else i need to know about my PSU before i try out my rig.electronics do not consume voltage, they consume amperage. you will be fine with only one 120mm fan and one 80mm fan on the same rail.I know that. I want to know if my 12 volt rails on my Powersupply can handle all the amps from my computer parts.Quote from: Shoota on January 02, 2008, 08:59:01 PM
