PSU Power over head
What % over head should we consider when I check to see that i have not planned to use to many watts for my PSU. atm i need to about 460W. Also how many watts does as something powered by the USB port use or does it depend on what u are using on it.
Power is directly related to all the parts you put into the system and run off the system. I think you should probably post what you are running, that might make things easyer. And if you want to go much higher than 460 you might want to look into a dual power supply system.
One other thing, it is very important especailly on expensive equipment to run a UPS so that you have a clean constant source of power. That way whatever power supply you use, it will be able to deliver the power needed.

Cheers and btw do u know out of interest how many watts is used when the USB is powering something or does it depend on what it is powering??.
Well, I am not sure of the exact voltage, but it is not very much. I do know that if you try to run too many USB devices off one port with out some sort of Hub that has power, they will be underpowered and not work. It is probably around 12 volts.
