I dont understand what it says about Peak and sustained power, also the cable says it needs 12v DC, and the power supply gives 650 watts. I don't understand any of this, can someone please explain this to me, and if this power supply doesn't work, please give me examples of ones that will work. Longest answer will get best answer.Thanks!
That Xbox power supply cable is pretty cool! I've never seen those before. Ok, as for the power supply questions: Peak power is the maximum amount of power the unit can supply for a short period of time (a few seconds at most). A computer, during start-up, will use quite a bit more power than once it has achieved steady state. This is because drives have to spin up, semiconductors have to power up, etc. Once everything is up and running, the power draw drops to nominal or steady-state Sustained power is the amount of power the unit can supply non-stop. When purchasing a power supply, always give yourself leeway. If a supply indicates it is 650 watts sustained and 80% efficient (gotta look at that efficiency!) then it can supply 520 watts of power continuously. Even at that, I wouldn't want to run it past 450 - 475 watts continuously. 12v DC is the high rail on a power supply. Different parts of the computer require different voltages to operate. Drive motors typically need the 12v DC, where as memory needs less than 3 volts. A computer power supply has different rails or supply wires which supply the following voltages: +12 volts DC, +5 volts DC, and +3 volts DC (there are some others but those are the key ones). I don't know what the power requirements are for an Xbox 360, but it obviously needs the 12 volt and 5 volt DC rails to power it. Anyway, the power supply you've listed above is more than adequate.
