Power Supply power draw?

Ok I am trying to prepair for a LAN party at my friends house, I want to find out if the outlets will support the PCs. What do I need to know? Things like amps being pulled vs. what the breaker can handle? What do I need to take into account? Do x watt power supples use x amount of amps? Is it a set number? I.e. a 300 watt power supply uses x amount of amps, a 400 watt power supply uses x amount of amps. Is there a site I can find these answers?

Thanks!
 
Well I dont know about fixed numbers..but I = P/E. Thus a 400 power supply would draw a max of 400/110= 3.6 amps max. or P=IxE thus as 20 amp breaker would handle 110x20= 2200 watts. But remember 400 watt PS does not produce 400 watts constantly in fact..seldom if ever. Im sure you could handle 6-8 pc's comfortably on a 20 amp ciruit and likely even up to at least 10.
