Well I finally found out why the XBOX 360 is getting so hot...Why the hell would you need 17.3 AMPS!! to run a console...what a waste of power!

First of..the 3 CPU cores take Microvolts..and almost no amps whatsoever.

The graphics card is probably going to take around 500 milliamps...but thats even way to high for a videocard...I think it might take around 5 milliamps instead of 500. (and it's not actually a card, it's two seperate chips)

The lights in the system are LEDs (Light Emitting Diodes), and they take almost no power at all.

The only thing I can see taking up the most power is the wireless 2.4 Ghz controller and the wireless lan connection (Which is also 2.4 Ghz..the bluetooth standard). Those use antennas so, I could see how it would need a good amount of watts to work.

The disk drive is negligible and so is hard drive..they don't even come close to using 1 amp.

WOW. That's pretty insane..17.3 amps for a console...I hope the next one they make conserves a little power...the Power supply is overheating in some of the XBOX 360's and that's why they're crashing and freezing.

What a waste. :x
 
Well, for starters the CPUs will use ~5v, not mv. From what I heard the thermal dissipation is on the order of 130 Watts or so. Also, bluetooth and wi-fi share the 2.4GHz band but they are not the same standard; Wi-Fi antennae put out at most 100mw. Where did you get 17 Amps from?

I'd conservatively expect the XBox to draw at most 350W at the wall - and since power is equal to voltage multiplied by current I'd expect to see a draw of about 3 amps on a 110V system or about 1.5 on our 230V.

Incidentally, the highest fuse rating you can get in this country is 13 Amps which does cast doubt on the figure you've given. I'd check the user manual, but the one on file at FCC is light on details.

Anyone with an XBox 360 should be able to read the bottom of the brick to see exactly what it draws. As for the overheating I put that down to substandard work from OEMs like Delta rather than any fault of Microsoft's.

Where did I get 17 amps from?? If you have the system, look at the seperate power supply..the transformer. The input is of course 120VAC from the wall outlet. It converts that to 17.2 AMPS DC current..which is HUGE!!
 
Haha, that's funny, especially since something like 1/3 of an amp can kill a human.
 
Hypothesis: Just because the power supply is rated for it, doesn't mean that the hardware is drawing all that current.

You're sure it's not 17.2 Volts?

If it isn't, then the power usage would be around 2kW which is quite clearly insane if you're saying that the XBox draws 17.2A @ 120V (Mind you, I never did get the hang of AC calculations).

Now we know the XBox uses 254 watts total and if it draws 17 amps then the voltage must be about 15 Volts, this is reasonably believable if you're talking about the secondary side of the transformer.

But if you're talking about what it pulls from the wall, which is of course what really matters, you'd expect to see less than 3 amps drawn from the wall socket at 120V or a little over 1A at 230V. This is more in line with what I'd expect to see and it's important to note that this peak power usage not idle.

If you're concerned about how much it's going to cost to run your XBox then look at the Power usage (254W peak), not the current. So, if you leave your XBox running all day and somehow manage to get it to work at peak power all day then you can expect your bill to be 6kWh heavier but this is pretty much academic.
