Yes easiest way do a google search there are a few, sata hard drive dont require a signinficant amount of power its you cpu and gfx card that require alot of power and that depends on the card and cpu themselves. I think a P4 is between 75W and 95W. i use this one http://www.jscustomp...m/power_supply/.

the site is quite outdated...... and there are something that i not really understand.
Is a one slot 256 DDR SDRAM uses the same power as a 1024 DDRSDRAM? Is a 120GB sata hardisk consume the same power as a 250GB sata hardisk? How much do 2 MSI 6600GT SLI consume?

i am using gigabyte GA-K8NXP-SLI motherboard which have a card name K8DPS which known as dual power system. It stated there that the dual power system could supply a total 6 phase power circuit design. So, did this add on the power of my power supply? what is the difference between 3 phase power and 6 phase power.
